Top 5 Best Whole House Humidifiers 2018

Buying Guide: What is a Whole Home Humidifier?

For all they do, whole house humidifiers aren’t terribly complicated. For the simplest explanation, you’ve got two major types of humidifiers that can assist in your home:

1. Strong portable units.

Portable units, not surprisingly, are movable humidifiers that can comfort homes up to 3000 square feet in size. The most common type is evaporative units that blow air across a wick filter. Water makes its way up the wick and evaporates as dry air moves over it. The wick moisturizes the air and does away with unwanted particles. The fan then pushes out clean, invisible moisture.

2. A unit attached to your existing ductwork.

While there are a handful of different types of these units, the principle is pretty much the same. Just like a portable unit, it’s going to put moisture into the air through a similar principle of introducing moisture from water and evaporating it into a warm air stream produced directly from the furnace. The difference, however, is that this unit works as a humidifier for the whole house using your ductwork, so every room that has an air vent is now putting out air with the right balance of humidity for comfort.

Best Whole House Humidifiers

Each type of whole house humidifier is controlled by a humidistat, a device that can set to a moisture level that is comfortable for you.

Exactly which kind you need is really up to you and your circumstances. For most homes, a hot-air based system will cover everything you need because your system already runs through your home, thus your whole home humidifier can get to everything easily. If, however, your heating system doesn’t completely run through your house, either because you have added an extension or you just don’t prefer to use your system at all, you would probably have more luck with a portable setup.

While both units will cover the whole home, you may find that the portable unit is easier to reach and maintain, but it does require constant emptying of the tank, usually daily or every other day at the minimum. The cost for one is also less but you may find yourself looking for the proper placement for humidity to stretch throughout all corners of the home. Either way, both types will make your home much more comfortable, whatever the season.

What Are Benefits of a Humidifiers for the Home?

Because a home humidifier makes all the air in your home more comfortable, it takes care of a lot of problems you might not have ever considered before. As we brought up earlier, an environment that’s more arid will also allow certain viruses to thrive. What this means for you is that you’re going to be putting a lot more pressure on your immune system in two ways; the dry air allows the viruses to travel more easily, as well as keeping the helpful moisture out of your respiratory system to combat them.

In addition, folks living in big cities or other areas with particularly bad air pollution will feel the effects more in dry air than in other places. Without any moisture in the air to dilute it, pollution from larger cities can really contribute to respiratory problems like asthma and allergies, especially in young children.

Would you believe that a home humidifier can also make your home feel warmer, causing you to use your thermostat less? By mixing water into the air, a whole house steam humidifier can actually make the air around you feel warmer without the need to turn up a thermostat. Particularly in the cold, dry months, this can really add up to savings on your utilities bills.

Finally, having no moisture in your air can start to affect your home as well. Because the wood in our homes still depends on a small amount of moisture to keep its shape, being in an environment that’s too dry can cause the wood to warp and crack, as well as paint to chip.

While this can look bad and cause your older wooden furniture to show deeper wear and tear, it can also compromise the strength of your home’s supports and foundation. By introducing just enough moisture to let your wood keep its shape, you can keep your home standing strong for longer, without the need for costly repairs.
