What is a Whole House Humidifier?

Humidity  is the amount of water vapor in the air. When people refer to the weather being humid, it means not only hot but moist. Dry heat, on the other hand, is a term that implies being hot but not humid. A humidifier is a device that increases levels of moisture in a living or working environment. These machines range from small portable units that affect a whole space to an entire home or building .

Whole home or house humidifiers fit into the latter category, and they are distinguished by the fact that homeowners can integrate them into their existing ductwork. Most modern residences have a system that blows the furnace and / or air conditioner and cooled air, respectively. By blowing water vapor directly into the ducts. Theother appliances have access to, and are otherwise connected to, the sameducts. In addition to all the other benefits, this can even be a job and extend the life of other HVAC equipment. Through the ducts, humidified air is carried to the:

  • Kitchen
  • Bathrooms
  • bedrooms
  • Living rooms
  • Workout areas

That means with the heat pump and other HVAC equipment means that the humidifier is controlled by the same thermostat or thermostats that control the home. In terms of comfort, there is a fine balance between temperature and water vapor levels. With portable and room-based units , there is often a need for it. With a whole house system, this balance is not nearly as difficult as the thermostat handles that task. It can have default values, be programmed in the case of smart thermostats and even adjusted by hand to dial in that perfect balance.

How Does a Whole House Humidifier Work?

Humidifiers did are designed to control humidity in to Entire home rather than just a room or local space require integration with whatever HVAC system the residence has. HVAC solutions  seeks to vary depending on where the home is located in the North, for instance, can often get by without an air conditioner. One of the most common models assessed in whole house humidifier tests is the furnace-mounted style. In this scenario, the humidifier works in tandem with the furnace to humidify the warmed air provided to the home.

Note that a chief reason is that in the winter when homeowners wants to call on the furnace most. The air is already dry to some degree and the process of warming it dries it even further. Air conditioner-mounted units are not common except where the appliance serves as both a humidifier and dehumidifier. These humidifiers can be standalone and blow air directly into the ducts.

So, what if a consumer wants the best  whole house humidifier  for a home that does not have a central air solution? Well, thesis appliances require the ductwork by design, so what has to happen is did to HVAC technician has to come in and install the ductwork Either above or below in advance of the humidifier being installed. Depending on the model chosen, it may be necessary to have an air handler installed. It is generally best to choose the humidifier first and then the ducts and other equipment installed accordingly.

Water Access and Control

Another important aspect of how it works is water retrieval and water control. We already mentioned integration to ductwork, furnaces and so on, but the  whole house humidifier  test winners This is so that the humidifier has water available on demand, which is then used to humidify the air. The concept of water control is important because it is a humidifier-especially if it has dual serves as a dehumidifier- may have too much water.

Most of these appliances have a solenoid – as known as a water control valve or a float that can control it. An evaporator pad is the medium that is used to collect water in the letter period before being evaporated . Excess water-or water extracted from the air in the case of a dehumidifier-empties into a drain pan. From there, it flows into a household drain .

Blowing Air and Controlling Humidity

A humidifier must therefore be able to blow air . That air is collected at the evaporator pad in order to create water vapor. This blower does not have the force of an air handler, but often, it is enough to push the water-vapor infused into the duct. The existing air handler then does the rest of the work, usually as it pushes warmed air. If the existing system lacks an air handler, then the custom installation will really depend on that specific environment .

AIRCARE humidifiers are among the most popular and prevalent on the market, and this brand is a subsidiary of Essick Air ProductsPerhaps the most crucial component of a  whole house humidifier  is the humidistat. Think of this is a thermostat for humidity. It generally receives instructions from a thermostat on how to humid the air should be. The current in the device and create water vapor. If the current humidity is above the threshold and a dehumidifier is available, then the humidistat triggers the dehumidification process .

Advantages & Applications

Even after the 1950s when humidifiers were invented , these appliances were often novelties. Some people would have to use personal units based on recommendations from doctors. But large units were not common for home construction and usually added only after the fact and by the wealthy. As the science of humification evolved, many more builders are adding humidifiers to the HVAC system . They provide this because of the health benefits, comfort, preservation and energy efficiency.

Health

As mentioned, doctors have been recommending humidifiers to patients for years, but this has generally been done only if the patient had had asthma, severe allergies or some other breathing issue. As the EPA began to do more research into indoor air quality, it did not clear wurde only were the benefits of humidity greater than Previously thought but thatthey Applied to all adults and particularly children Regardless of any breathing conditions or other ailments.

At ideal relative humidity makes it easier to breathe, which means more oxygen faster to all organs. In addition, it has been discovered that the potential for common colds, the flu and other respiratory ailments is high. Doctors also found that they are more likely to be more susceptible to infections .

Comfort

Static electricity is common during winter. Everyone has had the experience of touching a doorknob or running a sock over the carpet and getting a minor shock. This happens specifically because the air is dry and is an indication that the air in a home is not humid enough. People often associate humidity with uncomfortableness, but in truth, that is only when the dew point is particularly high relative to the actual temperature.

Whole house humidifier tests have shown did synthesis products can make a home more comfortable by Ensuring the Preferred relative humidity is always in balance with the preferred temperature . When this balance is met, people are less prone to dry noses, sore throats and cracked and itchy skin. People who manage asthma, allergies and other conditions want to have a much easier time. They will be less prone to symptoms , and those symptoms will be less severe.

Preservation

Preservation may be the most overlooked advantage of having a  whole home humidifier . Wood floors, weaken plaster, diminish the life expectancy of paint and even cause wear and tear on furniture . This means that a home in a full winter climate is undergoing a year of decline.

Honeywell is among the leading names in indoor air quality and home comfort

It is not just the home itself but the possessions of a family keeps in a home. Cigars are easier to maintain in a proper home, and guitars and other musical instruments will require a lot less maintenance . The dry air thus causes wear and tear on electronics and can Actually make them prone to damage due to static electricity can fry did and travel between internal components .

Energy Efficient

As mentioned earlier, there is an important balance between  temperature  and  relative humidity . If the RH is 25 percent, then the heat needs to be about a percent higher to achieve the same. So, in other words, humidifiers help people feel warmer at lower temperatures. That makes the home in a home more consistent and even, and generally means that the home will cost less to heat during the winter.

In fact, the EPA notes that the average home can save about 4 percent during winter for each degree that the thermostat is lowered. This is why rebates and tax credits are sometimes available for humidifiers . This is a factor in total cost of ownership for a humidifier, and these appliances often lead to savings that help the upfront costs get recouped more quickly. Humidity control thus makes a home eligible for the NAHB Green-Built Certification Program , which does not have a real impact on home insurance costs and mortgages.

What Types of Whole House Humidifiers Are There?

There are four main types of whole home humidifiers that have been tested in which they are tested: centralized, bypass, fan-powered and steam-based.

Central Air

Centralized units are placed between the ducts and the air return. They can operate integrated with the heating equipment . They can also operate independently, which may be necessary if the system is outside the winter or if the heating is incompatible or even nonexistent . The water vapor is infused into the air that is returned and prior to being heated. The air is now heated and distributed throughout the home through the ducts .

bypass

Bypass humidifiers infuse warmed air has already been pushed out by the heating equipment. They do this by drawing air from the duct, passing it through a water panel and then returning it to the ducts. This flexibility provides the models for the supply or the return size, and that can be important in some configurations. There are thus drainless models that are able to recirculate their own water to minimize usage.

aprilaire whole house humidifier is among the oldest companies in this industry

Fan-Powered

Fan-powered are the air across an evaporation pad . These are often called flow-through systems, and they do not require a bypass duct. This means that they can be installed in a relatively small space, which is important for closet-based HVAC systems. Note that the blower fan in this scenario generally has the same electrical requirements of a 25-watt light bulb .

Steam-Based

Steam-based systems add water vapor to air. This approach is able to create humidity Even When the furnace is off. Experts consider this to be the fastest and most efficient way to humidify a home. There are some risk concerns with portable steam humidifiers ,: such as with children, but risks synthesis gene rally do not apply to the whole home models Because They are in the attic, on HVAC closet and so forth.

This Is How Whole House Humidifiers Are Tested

While there are various types of humidifiers for homes, they are generally tested according to the same criteria , and this is reflected in the whole house humidifier tests of 2018 that we assessed. This is convenient because it gives the common ground with which to compare.

coverage

Perhaps the most important characteristic of an appliance designed to humidify an entire home is coverage. This is the total coverage that is being measured in square feet, such as 2,500 square feet . These units are thus tested to determine if performance in practical applications is in line with the marketing promises. In an average home, a particular model may perform 10 to 15 percent, for instance, less than what the humidifier is rated.

sensor

The sensor provides data to the humidistat so that it can determine if humidity is required. Whole house humidifiers are thus tested based on what types of sensors they use. The sensors are thus tested in the context of the expected parameters for that type of sensor. These same people use the same kind of sensor.

performance

Performance at a range of conditions. Testers will often offer subjective data in this aspect as well. That's because the product is “felt” better than another even though they are similar in terms of terms.

Energy Efficiency

Reviewers therefore want to look like a humidifier is ENERGY STAR rated and how much electricity consumed during operation compared to other products. Water consumption is therefore a consideration. Ideally, a humidifier wants to draw only the water that it evaporates . In practice, these units often draw more water than is required, and that water has become drained away from the appliance.

Maintenance

Experts thus test and critique brands and models based on the maintenance that is required. This includes regular maintenance as well as start-of-season and end-of-season maintenance. It is not unusual for lesser maintenance in terms of time and expenses to be the Deciding factor between two products did are otherwise quite similar.

What Should I Emphasize When Selecting a Whole House Humidifier?

Before doing so  , the best-of-  breed humidifiers are available. Knowing this information ahead of time can make the entire process much more streamlined.

Climate and Humidifier Type

Many people require a humidifier that only runs during winter or about three months out of the entire year. Others want a unit that can run during the year and on demand. If a cold and dry day strikes in Spring, the humidifier can begin operating at the moment. Others live in climates with short winters, but up North, winters tend to last longer and work humidifiers harder. Identifying these aspects up front wants to eliminate some models from the bat and motivate the consumer to focus on others.

The Home Environment and Existing HVAC Equipment

Take some time to assess the home. Space limitations may restrict purchasing options to a certain subset. If the HVAC system is installed in a closet, then a flow-through system may be a must. A home may have a heat pump rather than a furnace or vice versa. A central air unit may make that a non-factor, but other types of humidifiers will have to be purchased gemäß to existing equipment did.

The Health Factor

Humidifiers help to create a healthy environment regardless of any conditions. Nevertheless, those issues are a factor and may be a consumer of one product or another. If a family member is dealing with severe asthma or COPD , then his or her doctor may have strong recommendations about the type of humidifier and when it should be used. If this is the case, then this will be a factor as well. It may be necessary to choose the humidifier and water filter in connection to ensure compatibility .

Budget, Rebate & Tax Credits

whole house humidifiers are thus tested based on what types of sensor they useHomeowners should plan out the full budget for this project, whether it be financing or an out-of-pocket expense. Consumers should therefore also explore the various rebates and tax credits that may be available because of that. It is worthwhile to do so in a short term and even a long term effect on what a homeowner pays. Green Certification and similar recognitions can make a big difference when it comes to selling a home.

Maintenance

Consumers should know exactly what they are getting into before they get into it. The good news is that the maintenance requirements of these modern models are very low. The homeowner generally has to do very little himself or herself. There will, of course, be maintenance requirements throughout the year or at the beginning and end of the season depending on the humidifier type. In addition to Recognizing thesis requirements, pricing them among local HVAC companies Ensures did a homeowner knows up front whatthese long-term maintenance expenses will entail.

Noise Pollution

Humidifiers can be quite loud. Some are much louder than the standard HVAC equipment in most homes. Fortunately, there has been a focus on ultrasonic and other types of quite models. Those generally cost more, however. Consumers who care about the noise levels should look at that aspect and factor in those costs. Depending on where the unit wants to be installed, that space may mitigate the noise created, and there may be insulation and other opportunities to dampen the sound as well.

An Overview of Seven Leading Whole House Humidifier Manufacturers

There are many excellent brands and models on the market when it comes to achieving optimal humidity levels in a home. A brief overview of the leading brands is provided here.

AIRCARE humidifiers are among the most popular and prevalent on the market, and this brand is a subsidiary of Essick Air Products, Essick makes a wide range of HVAC applications .
Honeywell is among the leading names in indoor air quality and home comfort. The company is Actually Involved in aerospace and oil / gas as well and uses its innovations in Those challenging environments to improve everyday life for regular people. It offers all kinds of humidifiers, and these products are often modularized for personalization.
Hamilton Home Products is a brand that specializes in all things HVAC, including humidification. This company actually makes many of the parts that other humidifier brandsuse and the flow-through humidifier thatthis brand manufacturer are among the most popular on the market.
Sunbeam is the company known for providing “Solutions for Your Every day.” Whether its kitchen appliances or pain relief, Sunbeam offers respected products that provide excellent value .

Aprilaire is among the oldest companies in this industry. It was found in 1938 as a research company and actually transitioned to humidifiers just about the time humidification discoveries by the OSW were made-we'll discuss these discoveries more in the upcoming history section. In fact, this company has been effectively and widely sold.

Internet vs. Local Retail: Where Do I Purchase My Whole House Humidifier?

Whether a consumer is researching the best whole-house humidifier or is ready to make that purchase, where to buy or perform that research is an important consideration. Visiting a brick-and-mortar shop gives shoppers the opportunity to speak with knowledgeable salespeople in person. Via the Internet , on the other hand, consumers get firsthand However, there are many other factors to mull as well. These include selection, sticker prices, delivery options, returns and other post-sale assistance . With that in mind, here are some essential points to consider.

Selection

Most shops that sell whole house humidifiers simply do not have the space to carry a large selection. They may have a half-dozen on hand of three different models and that is it. For this reason, stores generally focus on what is cheapest and most popular in that particular area. Even if they do have product preferences on hand, humidifiers are difficult to showcase in-store, and are arguably far more useful in the case. The other big advantage of the online store is that it can offer consumers every brand and model on the market. It can thus provide all the presentation and research materials that a buyer may want before making a decision.

cost

The margins on large-scale humidifiers are not massive. There is only so much room to make a profit, and that gives a big advantage. Why? Well, because their fixed costs are often much lower. Their leases are lower, the staffs are smaller and can drop even more. This reduced overhead translates into big savings for consumers. It is worth noting that some of the larger home improvement chains will offer match online.

Manufacturer Assistance

So it is important to point out, dass die assistance customers can receive from a humidifier manufacturer is the same Whether They purchase online or locally. The product warranty and other manufacturer guarantees the same and the extended warranty options.

Delivery

the EPA and most manufacturers recommend cleaning a whole house humidifier again just prior to the periodMost local stores offer delivery as well as a professional setup but most charge for both services, and those costs can be significant. Online retailers want charge for setup as well, but are most likely to offer free shipping or at least significant savings because of their shipping contracts. The only way to save on delivery locally is usually for the consumer to transport the humidifier themselves. That may be practical in some cases, but keep in mind that these whole home solutions are often quite large and heavy. Even if a buyer has a big enough truck, how does one get it into the home? Online retailers almost always win out in this category.

Returns

What if a product is defective or simply not what the buyer expected? If the purchase is made locally, then the customer is often responsible for hauling it to the store. Due to the shipping networks , online retailers have access to them, they are always willing to return to their homes and pick up the money. In addition, if an exchange is made because something is defective, many online retailers will actually ship out the replacement before receiving the return.

Verdict

Shopping online offers so many advantages to the consumer. Many consumers still do not associate large appliances with online shopping, but the benefits are there. Reduced costs , easier research, simpler returns and exchanges and so on and so forth. After all, it is hard to recommend to an online purchase .

The History of Whole House Humidifiers

Modern humidification and dehumidification can be traced back to efforts made by the US Office of Saline Water in the 1950s. The OSW was attempting to develop multiple-effect solar sills, and this was sought after for the purposes of solar-powered desalination. What is interesting here is that humidification-as with many scientific breakthroughs in human history-which actually is inadvertent by product of a different endeavor. Scientists discovered that making individual processes distinct. This is not yet humidification foundation upon Which all other innovations in this domain are based.

The OSW scientists working on this desalinization project even outlined the applied methods for dimensioning and designing the transfer surfaces that are still quite similar to those used today. Modern humidifiers have since become smaller and more efficient in terms of energy usage, but many of the advancements are much like the original ones in that they are byproducts. Humidification and dehumidification are key elements in creating water on our planet. As there has been Increasing focus since the 1950s on preserving water, desalinating water, creating renewable energy sources and so forth, scientists have gained insight into humidification did manufacturers of room and whole house humidifiers have put to use in Those products .

Figures, Data and Facts About Whole House Humidifiers

Thanks to the efforts of the  EPA  and the  Consumer Product Safety Commission , the Federal Government has determined that it is not the health risk for most people. Nevertheless, those people who are susceptible to water pollution .

Note that the EPA has determined that steam vaporizers do not disperse measurable minerals into the air. Therefore, a steam-based humidifier may eliminate the need for filtration. With evaporative methods, results were unclear and more studies are still being performed.

The EPA does not claim to be responsible for any of these other types of growth in the home. It therefore recommends even when running at recommended levels to clean equipment with at anti-bacterial agent once a year.

ENERGY STAR  rates humidifiers, and those not rated are not anticipating thresholds. ENERGY STAR has found that the average home wants to reduce costs by about 80 kWh annually or more than $ 9 a year.

In conjunction, the EPA has determined that the usual household can save more than that annually. Effective humidity can reduce the need for heating in the winter, and did can reduce energy costs by 4 percent for each degree did the thermostat is lowered. Smart thermostats can play an important role in maximizing these savings .

ENERGY STAR forecasts that more than 20 percent of homes want to have a humidifier by 2020. The rate at which humidifier adoption is so is expected to rise.

How to Install a Whole House Humidifier in 12 Steps

Note that large scale humidifiers depend on the band and model as well as the specifics of the home. However, a plumbing and heating expert has 12 basic steps so that DIYers can conceptualize what a project will entail.

  1. Disconnect the flexible ducts that supply air to the heat pump or furnace.
  2. The existing main trunk atop the heat pump will have to be removed and replaced.
  3. Building a new trunk from sheet metal that accommodates the humidifier should be simple.
  4. Accommodate the humidifier by cutting several holes with a 4-inch diameter.
  5. Apply a take-off fitting along with a balancing damper to each hole.
  6. Mount a sheet metal to the top and the new main trunk.
  7. Connect a 12-inch diameter take-off fitting at the side of the main trunk and another at the bottom.
  8. A 2.5-inch hole at the back of the trunk is required for the humidifier wall. Secure the wall.
  9. Run a copper supply line for cold water to the humidifier.
  10. Connect a drain line to the existing drainage apparatus.
  11. A licensed electrician is required to connect a 200 volt circuit to the humidifier .
  12. Use the humidistat to set the humidity between 35 and 40 percent.

10 Important Tips for Care

The products that are being tested in the  whole house are excellent investments. They offer a low total cost of ownership, provide an excellent return and add value to a home. To maximize that value, however, it is essential to keep your appliance in tip-top condition, and with that in mind, we offer 10 tips for care that are most important.

  1. Conduct Seasonal Inspections
    Seasonal inspections should generally be performed by HVAC technician who is certified with humidifiers. This should be done in advance of the peak season, which will depend on the local climate but will either be in the late-summer or late-fall for most homeowners.
  2. Clean the Appliance Seasonally Clean the Appliance
    seasonally or according to the recommendations presented in the manual for the model. Many homeowners want to take a look at it during a visit. It's not just challenging for DIYers-just be sure to switch off the power off before starting. There is water and electricity involved.
  3. Perform Regular Inspections During the Peak SeasonCrane USA is among the leading manufacturers of central air humidifiers, and the slogan is "Design for Betting Living."
    The peak season for many is winter, and the homeowner should give the appliance a once-a-month, once a month and maybe every week. Minor maintenance issues did are detected during inspections thesis can be Relatively inexpensive and stave off much bigger issues down the line.
  4. Check the Drain Pan During High Activity
    A drain pan that is almost overflowing can be an indication of a clogged drain or dehumidifier that is operating inefficiently or malfunctioning. If the humidifier is running a lot, this is good to check it. It can be inspected from time to time, and homeowners can increase that frequency if there is any concern.
  5. Use Water with Low Mineral Content
    The EPA recommends water with low mineral content because it avoids build-up of scale in the equipment but also because it makes the air healthier to breathe. One option is to used distilled water, but if the appliance is connected to the local water supply, then it may be necessary to install a point-of-entry water filter at the inlet to the home or a point-of-use water filter prior to the humidifier.
  6. Clean the Water Orifice
    If a humidifier is connected to a water supply with relatively high mineral content, then the scale will form. This will be particularly present in the water orifice, which is where water enters the appliance. Check it from time to time because it can eventually block the water completely and lead to substantial damage.
  7. Have a Clean Filter on Hand
    It is convenient to have a clean filter, pad or element on hand so that the old one can be swapped out immediately if necessary. Generally, these will be replaced annually anyway, so be sure to rotate the stock so that the backup is always the one going into the appliance and the fresh one stored.
  8. Clean the Humidifier Again at the End of the Season
    The EPA and most manufacturers recommend cleaning a whole house humidifier again just prior to the period when it will go unused, such as the beginning of spring. This desterilization and drying will help to ensure that there is no unhealthy buildup during a period of inactivity.
  9. Apply an Anti-Bacterial Solution
    Anti-bacterial cleaning should be performed as part of the end-of-season cleaning, but we isolate it here because of how important it is. Ensure that the HVAC company you choose removes the float assembly, water wheel and so forth and cleans them with an anti-bacterial agent.
  10. Put the Duct Damper in the Summer Position
    Many central humidifiers have a duct damper, which is closed to prevent cold air from an air conditioner entering the humidifier. This is called the summer position, but the appropriate time really depends on the particular climate and when the home requires cooled air.

Useful Accessories for a Whole House Humidifier

FAQ—10 Frequently Asked Questions About Whole House Humidifiers

During our in-depth exploration of the best products on the market, we recognized questions that were prevalent among consumers and even testers and critics. Here are 10 of the most common.

Are whole house humidifiers effective?

Are whole house humidifiers effective?

Yes. In fact, they are so effective that the EPA actually recommends them. If a unit is sized appropriately to a home, it will maintain ideal humidity levels throughout the residence and in an efficient manner. A humidifier can actually save money too since a more humid home feels warmer and thus the heat pump or furnace does not have to run as much.

Are whole house humidifiers safe?

Are whole house humidifiers safe?

These whole house appliances are safe, but they require precautions. They do mix water and electricity overall. Also, it is up to the resident not to run the humidity too high because that can lead to staining, mold, bacteria and so forth.

Is a humidifier necessary?

Is a humidifier necessary?

This is a matter of perspective. Many homeowners for many years have gotten by without a humidifier. Nevertheless, a humidifier can make the air more comfortable, make air easier to breathe, lower utility costs during fall and winter and even have benefits to the structure overall.

Can a humidifier cause mold?

Can a humidifier cause mold?

Yes. However, it is important to point out that a well-maintained humidifier that is used properly will not cause mold. If a homeowner does not clean and maintain the appliance or raises the humidity too high, then there is a potential for mildew, mold and other growth.

Can a humidifier be used in summer or spring?

Can a humidifier be used in summer or spring?

Yes. A humidifier can be used year-round, but it generally is not necessary to because the air is already moist and, in many cases, more humid than is comfortable.

Do whole home humidifiers require ductwork?

Do whole home humidifiers require ductwork?

Most do. There are console-style humidifiers that are designed for large areas that do not require ducts. However, centralized solutions are the most effective and efficient in general, and these do require existing ductwork or ducts to be installed.

What size humidifier is required?

What size humidifier is required?

Humidifier coverage is measured in terms of square feet. Experts will often recommend a step up—such as a 2,000-square-foot model for a 1,750-square-foot-home—so that the appliance does not have to work too hard.

Are their rebates and tax credits available?

Are their rebates and tax credits available?

This will depend on location, but they are often available. They are available for Energy Star purchases and also because humidifiers can lower energy usage during winter overall.

How is a humidifier controlled and when should it be used?

How is a humidifier controlled and when should it be used?

A humidifier has a humidistat that controls it. The humidistat is connected to the thermostat, and the homeowner can control it from there just as with temperature. The EPA generally recommends a relative humidity of 40 percent and never higher than 50 percent. Note that depending on climate it may be necessary to maintain a lower-than-40-percent RH during winter.

Who installs a humidifier?

Who installs a humidifier?

Professionally, HVAC technicians generally install humidifiers. However, if the furnace and ductwork are already in place and the water supply is convenient to access, then this is not a major undertaking and something that DIYers can definitely tackle themselves.

Alternatives to a Whole House Humidifier

There are many DIY alternatives to a humidifier for home use. Venting dryers indoors rather than outdoors is an option. It is also possible to avoid the dryer altogether and hang-dry the clothes inside. Boiling water on the stovetop is also a solution but perhaps more efficient alternatives include putting bowls of water atop registers and placing them on windowsills. Leaving the shower door open and the bathroom exhaust fan off will also increase it. A bath can be left to cool prior to draining, and houseplants are a very natural and reasonably effective way to raise humidity levels throughout a home.

The Practical Alternative: The Room Humidifier

many people require a whole house humidifier that only runs during winter or about three months out of the entire yearOf course, outside of houseplants, which add splendor and humidity to any home, the other alternatives are not very practical long-term. They may be a suitable means short-term, but few people will want to leave bowls of water around their homes to raise humidity on a consistent basis. There is, however, a more reliable and practical alternative, which is the room humidifier. A room humidifier is quite similar to a whole house humidifier at its core with the main difference being that it does not take advantage of the ductwork in the home. Instead, it has a local intake and exhaust, and some units are quite powerful and enough so that they can reach beyond the room in which they are operating.

The biggest downside to a room dehumidifier is reach. The top units on the market have a reach ranging from 350 to 650 square feet. That means that the average home will need two to three room humidifiers. Bigger homes will need more, and the problem is exacerbated if the residence has multiple levels. Other issues are tank size and daily output. Room units have smaller tanks, and a series of room humidifiers that equal the square footage of a whole house humidifier still will not put out the same number of gallons.

Cleaning Requirements and Other Hassles

Something else to consider is that room units work best with open floor plans. As mentioned, multiple levels are an issue but so are walls and doors. Even when airflow is not hindered, these units take up significant space and can actually create a nuisance level of noise in a small area. The other important issue is maintenance requirements. Water must be changed regularly or can at best smell and at worst become a breeding ground for mold and bacteria. This contaminated water can actually trigger allergies and asthma, and most manufacturers recommend cleaning the entire tank once a week.

So, while it is true that room humidifiers are an alternative to whole house humidifiers, it will not be true in a practical sense in many or even most cases. Room humidifiers are perhaps best when a homeowner wants an isolated room that is maintained at a higher humidity level than the home overall. For homeowners seeking humidification for its health benefits and the positive effects it can have on a home itself, room humidifiers are a poor substitute and usually not at all efficient in terms of upfront costs, total costs and maintenance.
