The best type of whole house humidifier
The three basic types of whole house humidifiers are the bypass, fan powered and steam humidifier.
1) Bypass humidifiers:
These humidifier type work by taking in air from the furnace duct and passes it through a water panel, before delivering it back into the duct then your home. The air that passes through the water panel comes out with a high level of moisture which it carries to the atmosphere. This type comes with the option of a drainless bypass if you don’t have a draining floor, which also helps to minimize water usage by circulating its water.
2) Fan powered humidifiers:
They employ the same technique as the bypass type, but with the presence of a fan that blows air across the water panel for an increased level of evaporation. These humidifiers generally can produce a gallon more than the bypass type per day and can be installed in smaller spaces.
3) Steam humidifiers:
This type of humidifiers makes use of electricity to heat water till it becomes steam, releasing it into your ducts and then the atmosphere of your home. It makes use of a blower in pushing the steam through, and offers the fastest and most naturally efficient way of raising your moisture level regardless of your heating or air conditioning situation.
The bypass and fan type are less expensive and are easy to install, but the bypass requires a lot of maintenance and frequent part replacement, while the fan type requires a constant running water line and isn’t as efficient as the steam type.
On the other hand, the steam type is the best for your whole house humidification, as they are generally more productive and poses a little risk of mold, although they are expensive and more difficult to install.

The Aprilaire is one of the best humidifiers out there, designed to release an impressive rate of about 334.6 gallons of moisture per day into the air.
The unit is well built and lack the presence of a conventional water bucket like many humidifiers, but makes use of a system that allows it to be connected to a large water source in the home. This removes the stress of having to fill the water bucket every now and then.
It contains a steam generator that works effectively with either a hard or soft water, eliminating the constant need for distilled water in a modern humidifier. In fact, hard water is even more advised due to its high conductivity; this is tagged electrode technology because electrodes are used for heating and hard water aids the steam producing canisters in steam production.
According to room size coverage and the amount of steam released per day, we would recommend this unit as one of the best for you. Although its initial cost is expensive, it’s a worthy investment. Be sure to expect some running costs still, as the filters would need to be changed regularly.

The honey well HE360A1075 is a really portable looking humidifier but is very efficient in performance. It allows for options to be mounted in the home, preferably a furnace or AC system where it’s moist can quickly be circulated round the house. Like the Aprilaire, it also makes use of the continuous water system that eliminates the need for a water tank.
This unit is built to maximize efficiency while conserving water usage and therefore, giving you a lower electric bill per month than you would normally have with a humidifier.
Although the unit lacks the presence of an inbuilt humidistat (it comes separate from the unit) for auto or local regulation of humidity level, a salient switch can be purchased separately that can be attached to control the board, alongside a pressure switch.
These switches ensure that the furnace is running and the air is flowing correctly before the unit is allowed to engage, but you still have the option of running it without the furnace, by switching the fan on the thermostat on.
In all the unit would work well in most conditions and is an excellent pick for whole house steam humidifiers, working mainly as a furnace humidifier that puts out a right amount of moisture. Its installing is quite easy if you are handy with the required skills, and would take about 2 – 3 hours at an average.
Special features: humidistat, dimensions 18 x 18 x 27.25 inches, auto regulation, good looking piece of furniture, caster wheels.
The AIRCARE EP9 800 evaporative humidifier is unlike the first two units reviewed before, with the size of a mini water dispenser without the tank on top of the course and control buttons by the side.
It is a portable complete humidifier because you don’t have to accurately install like the others, as it is just to be placed in a suitable corner of the home where it can quickly add both beauty and moisture to the environment in the home.
If you intend purchasing a humidifier for that really large whole home of yours i.e., whole house humidifier, then this is probably not best for you. The unit does a decent job in putting out moisture but has a very small coverage area, and with the water tank built inside, you might have to refill every now and then, unlike the others that can be connected to the water system of the home. You can always check the water fill line at the front side to know the current water level at any moment.
In all, the evaporative humidifier looks beautiful and does the job of getting water into the air well, using a standard wick which can be easily replaced if need be. It can run for a long period without much issue and possess caster wheels for easy moving around the home.

This water is then wicked up. Other models just keep running water until it is told to stop by the humidistat.
The humidifier is compactable and can be installed with a furnace, possessing two valves that should be installed along the hot water line, although many have reported problems with these valves. If you would purchase the device, be sure to ready a separate budget to purchase those items.
Although the 500M isn’t as powerful or possessive of many features like the 800 model, it does a decent job, with the advantage of being installed with a furnace. It can cover homes with bigger sizes unlike the AIRCARE EP9 800 and would be a good buy at the price it goes for.
Special features: blower safety switch, 12.1 pounds, 7.6 x 12.5 x 12.6 inches,
This is a steam type humidifier that is quiet in operation, efficient and is recommended for low budget manageable purchase. Although it is certainly not as good as the rest, according to the degree to which it can increase the humidity level of the home or the size of houses it can cover, it still does a pretty decent job.
It is designed to serve a home of about 1,400sqft but has been tested to serve slightly larger capacities depending on the way the house is built and insulations, keeping the humidity level at 45% +.

How do whole house humidifiers work?
A whole house humidifier is installed directly with your heating system (furnace), being placed just close to the duct at the supply or return end. It also has no provision for water bucket like a portable humidifier but is instead connected directly to your homes water supply.
The humidifier contains a pad that could be located above or underneath; this continuously collects water that is then misted into the device and pushed out by a spinning drum, into the atmosphere.
Hot air from the furnace also enters the humidifier, which exposes it to the water inside. This water evaporates into the air and is released back into the air flow and later the house as a whole.
The air that went through the humidifier comes out, containing a high amount of moisture and when it joins back with the rest of the air flow in your home, it increases the humidity by a high degree effectively.
Evaporative humidifier vs. Steam humidifier vs. Ultrasonic humidifier
The evaporative humidifier works by drawing in air from the atmosphere, then passing it through a wick filter that absorbs water from the reservoir. The air then absorbs moisture into itself and is released into the atmosphere, therefore raising the humidity level. They are generally noisy and requires frequent filter replacements.
While the ultrasonic humidifier makes use of vibrating metal plates that brakes the water particles in the reservoir which is then emitted as a fine mist, the major drawback is its tendency to leave white mists on furniture surfaces in the home, although they are very quiet and more efficient but also more expensive.
The steam humidifier uses a natural heating element to boil the water until it becomes steam and then uses a blower to release it into the atmosphere. They are the most effective type ho humidifier, although they are mostly the whole house and could be more expensive.
Furnace humidifier maintenance
Carry out these procedures per month
- Turn off the unit
- Unscrew the humidifier to check the pad and drum. Clean or replace it depending on its condition.
- Clean the foam pad with a solution of water and vinegar, then rinse with clean water. If there is wear, replace the pad.
- Check to see if the water level is alright by allowing the reservoir to fill up after turning on the tap. If the drum rotates and dips into the water, then it’s on an ok level, if not adjust the float arm with the adjusting screw.
- Make sure there are no leakages and tighten using a wrench if there are any. Clean the outer portion of the unit also with the same solution
