Whole House Humidifier Benefits
Central humidifiers (or so called whole house humidifiers) are most recommended for home use in winters to improve the indoor air quality.
As these are specifically designed and hard-wired into a home’s plumbing and air heating systems, these let you enjoy balanced moisture in the home ambiance without any risk.
Some of the best advantages of getting these system installed into your central air ducts are:
✅ Do Not Over Humidify: As these duct based home humidification systems works automatically to provide the necessary humidification only when it’s needed, it does not over humidify your room.
This saves you from all types of mold, mildew and dust mites that may grow due to increased humidity in the air.
It has been seen that many portable units do not stop humidifying the air even when the necessary humidity level has been achieved.
This is due to the fact that these room humidifier lacks the humidity control regulators or regulating feature.
Whole house humidifiers being a smart device saves you from all these troubles of getting air highly humid.
✅ Low Maintenance: One of the disadvantages of using portable room humidifier is it requires changing the water every day.
Cleaning the reservoir (and other parts) along with thoroughly drying the tank is also required to prevent viruses and mold from growing.
Regular cleaning of filters is also essential for getting the white dust mineral deposits removed which are deposited as a result of evaporated tap water that contains minerals.
Whole house humidifiers on the other hand saves you from all these troubles of getting the unit cleaned and regular maintenance.
You can get your unit serviced once in a year which makes it run smooth all the time.
✅ Low Operating Cost: As mentioned before, many portable room humidifiers does not include a built in hygrometer to stop the unit after they have delivered optimum humidity in the room.
This can lead to wastage of power and hence higher electric bills.
However in case of central humidifying systems, these whole house humidifiers with built in humidistat come with a sensor to control humidity called humidistat.
This enables them to run automatically only when required (to achieve the targeted humidity). It does not keep running all the time 24×7!
This controlled featured to humidify the home, saves good monthly amount on your electricity bills.
Besides the power bills, room humidifier units need expensive distilled water to operate efficiently and to prevent the depositing of white dust minerals.
Whole house humidifiers on the other hand does not require any such purified water for operation and can save on your water purifier bills.
✅ Good Health and Maximum Comfort: Whole-house humidifier at your place keeps the humidity levels of the air intact thus making it easier for you to breathe comfortably.
Even when you are suffering from respiratory issues (like sinus, bronchitis, snoring and many more) you can keep yourself healthy, no matter in which room you are present in.
Other than the human aspect, air humidifiers are required to save indoor plants, pets and porous materials in your home.
Dry air can actually draw out moisture from the items (such as wooden furniture, wood floors, wooden musical instruments like guitars, etc.) to make them damaged soon.
And for this reason installing a good whole house humidifier that takes good care of all these items makes a sense.
✅ Most Convenient As It Works Automatically: One of the greatest benefits of installing central humidifiers is it can be connected to the heating, ventilating or an air conditioning system (HVAC).
These are hence bound to supply optimum amount of humidity to the whole house through your duct work (including all the rooms, kitchen, bathroom and even your small wine cellar at home).
As it works in an automated way to provide optimum humidity it is also considered as “install it and forget it humidifier device for your home”.
Simply speaking you never have to worry about the water tank getting dry as in the case of portable table top humidifiers installed in bedrooms or baby room.
Types Of Whole House Humidifiers
The main objective of installing a whole-house-humidifier (central) is to maintain ideal humidity level inside your home in an automated way.
However based on the difference in how they pump the moisture into the duct system, these are categorized differently into various different types.
Some of the major types are as follows:
Drum Type Humidifiers
This type of whole house humidifier comprises of a belt (made of foam or fabric) that takes up water when it rotates on a drum over a water reservoir.
When the air is blown by your HVAC system it passes over the drum which carries the evaporated water into your home for optimum humidity control.
Drum whole house humidifier systems are cheapest and easiest to install. You can even get them in a DIY way, without any need of a professional installation service.
However the drum needs regular cleaning and maintenance for to ensure there is no growth of molds and bacteria inside it. Also you need to replace the belt periodically for smooth working.
Flow Through Humidifiers
Flow through or bypass whole house humidifiers are among the most common ones which can be installed easily to your water supply line for efficient home humidification.
The air from your AC or furnace when blows through the dripped filter pad picks up the necessary moisture to force deliver it into your home.
Like drum type humidifier these also work by evaporating the water. But as these units do not use drum, there is no stagnant water and therefore very less chances of developing the molds and bacteria.
Based on above, the best advantage of installing a flow-through humidifier is the reduced cost of maintenance.
However it is to be noted that periodic cleaning and maintenance is required to clean away all the dust and dirt that gets clogged up to the filter pads.
Fan Powered Humidifiers
The working pattern of a fan powered whole house humidifier is the same as that of a bypass humidifier except for the fact that they contain a fan that blows air to the internal panel.
This is done to ensure that there is increased water evaporation and the electricity consumption stays at reduced levels.
Such kind of powered whole house humidifiers do not require much space for installation and are perfect for home built on slabs.
Steam or Warm Mist Humidifiers
Warm mist whole house humidifiers uses steam for adding humidity to the home. These require very less maintenance and should be installed on your supply line.
Electricity and water together works to create a warm steam at atmospheric pressure, which is then pushed into your ductwork in the form of fine mist – when your HVAC system is switched on.
Steam whole house humidifier uses the fastest and most efficient method to create and maintain a comforting level of humidity at home in a most affordable way.
However due to the risk of mold growth you need to inspect them regularly and get them serviced on time.
Evaporative whole house humidifiers generally work by passing the warm air through an evaporator pad which is saturated with water.
As this warm air passes through the pad it absorbs the water and get moistened. This moisture rich air is then passed throughout the home with the help of powerful humidifier.
Since these types of evaporative whole house humidifiers are also powered by the furnace’s fan, these should be installed in your ductwork.
Unlike steam whole house humidifier (which requires very less maintenance), evaporative humidifiers for your whole house should be replaced once or twice a year based on the usage.
If not the system’s evaporator pads may become a breeding ground for molds and bacteria due to over saturation.
As compared to other models, these evaporative units uses lots of water but little electricity.
Whole house humidifier models which uses ultrasonic technology (based on transducer) are usually less common.
Water when passed over vibrating transducer, excites the water molecules to break them into fine microscopic water droplets. These droplets are forced into the HVAC system to disperse into your home evenly.
Ultrasonic whole house humidifier systems are often costly as compared to other models and requires frequent cleaning due to the produced white dust.
Console whole house humidifiers are one of the bestselling in the market due to its low cost and portability.
Although these are not integrated to your duct system these are highly efficient in humidifying the larger areas, most of the times which may cover your whole home.
Just place them at your most convenient location in your home or building, sit relaxed and forget you even own a humidifier device to care for on regular basis.
Some of these console whole house humidifier models can also be installed like a window or a wall mount unit much like your room air conditioner.
As these are portable in nature, people also prefer using them for single large room, living room, large business meeting or conference space, banquet halls, etc.
Which Whole House Humidifier Is Best?
While the above are the most common types of whole house humidifiers used, there are also few additional types of whole house humidifiers for baseboard heaters, geothermal, air conditioners or for gas furnaces.
Well, if you are confused about which whole house humidifier is best to pick?
It may again depend up on various different factors.
Depending on your specific requirement, space and budget; you can pick the whole house humidifier that is best suited for your living.
How Do Whole House Humidifiers Work?
Investing in one of the above devices can help eliminate the need for several humidifiers around your home—saving you money.
But how do these more energy-efficient humidifiers work?
Unlike traditional humidifiers that are plugged into separate rooms, whole house humidifiers are installed directly into heating ducts.
This provides whole house humidifiers access to every room in your house, giving you ultimate control over the humidity of your home.
To control the humidity, your whole house humidifier will add water vapor into the air. This water vapor rests inside your home’s heating ducts and waits for traveling air.
When the system is running, this traveling air will make its way through your heating ducts and join with the water vapor.
The result is that the air being dispersed throughout your home has a higher humidity content.
Because this moisture-filled air travels through your heating ducts, it can effectively reach every room in your house. This makes it a much more energy-efficient option over traditional portable humidifiers.
It also means that you can enjoy even humidity levels throughout your house for the ultimate comfort.
But for those looking to install a whole house humidifier, one question remains.
How Much Water Does a Whole House Humidifier Use?
How much water does a whole house humidifier need to serve your whole house?
It’s a reasonable question for anyone wishing to cut down on their water bill—and for those concerned for the environment.
The good news is that whole house humidifiers are incredibly efficient in both areas.
But before we answer the question, let’s take a closer look at how whole house humidifiers get their water.
These systems are typically installed to tap straight into your water source. When the humidifier is on, it will be able to automatically draw water from your system.
This saves you the time and hassle of having to manually fill the tank yourself.
But does it take too much water? Are you going to be paying for this added convenience with high water fees?
The truth is that your humidifier’s water usage will vary.
If your home is rather dry, or if you haven’t used a humidifier before, you can expect the humidifier to use more water at first.
Many first-time whole house humidifier users are shocked at the initial amount of waste water produced—with some claiming it can be in excess of five gallons.
The good news is that once the home has adapted to a more humidified state, you can expect this to drop to two gallons or less per day.
This helps make whole house humidifiers an incredibly-efficient product.

Freezing water can cause failure in your ducts, pipes, seals and joints and it is therefore important that you do not install this type of device at basements or attic where the possibility of dropping the temperatures is quiet high.
✓ Maintenance needed: It is often very tempting for people to choose a device that needs very less maintenance.
