It’s old news that humidifiers are good for your health, especially in the colder months during cold and flu season.

But did you know that humidifiers are good for pretty much everything in your home? Your pets, your plants, your electronic devices, your furniture, etc.

And did you know that you could install a humidifier on your entire house instead of using the small humidifiers you place in every room?

Keep reading for a 5-minute guide to central humidifiers.

What is a Central Humidifier?

A central humidifier (also known as a whole-house humidifier) is a humidifier unit that connects to your home’s heating and air conditioning system to moisturize the air with water vapor in your entire house; this differs from smaller portable units that only treat one room at any given time.

Why Should You Install a Central Humidifier?

Central humidifiers range in price from $150-250, and you must hire a professional contractor for the installation because both HVAC and plumbing work is required.

That’s pricey and a bit of a hassle; you might ask, ‘Why not just use portable units in multiple rooms?’ Central humidifiers have unique advantages.

Advantages of Central Humidifiers

The reason most homes get dry in the first place is their heating and cooling systems, so by installing a central humidifier, you’re stopping the problem at its source.

Because the central humidifier connects to your plumbing, it gets its water directly from the pipes. It treats your entire home all the time, and you never have to refill any tanks!

A secondary benefit of the central humidifier’s connection to the plumbing vs. a water tank is that it has no standing water, so it’s less likely that bacteria will collect and release into the air.

Different Central Humidifier Models

The three basic models of central humidifiers are bypass humidifiers, fan-powered humidifiers, and steam humidifiers.

Bypass model humidifiers connect to your home through the furnace. With this model, warm air passes from the heating ducts through a tray of water, where it collects its moisture before going back into the ventilation ducts.

Fan-powered models work the same way as bypass humidifiers, except a fan pushes the air through the tray to create maximum water evaporation. Fan-powered humidifier models are more energy-efficient and generate up to one gallon more water vapor daily.

Steam humidifiers use electricity to boil water, producing steam that it pushes out into the ventilation ducts. Steam model humidifiers are the model that most quickly and efficiently maintain optimal humidity in a home, and they are compatible with any quality of heating and cooling system.
