What should you look for before buying?

If you want to be sure you buy the best whole house humidifier, you need to know how to look at each product and see what will make it effective for your home. We have done some homework for you!


The capacity of the humidifier is the first thing you need to consider. You need to match the capacity of the humidifier to the size of your home. If the humidifier is a small capacity unit, it can work well for a room, but it will not work for a home that is 3,600 sq. ft.

Amount of Water Required

Humidifiers require water to operate. Make sure you know the minimum and maximum amounts the humidifier you select requires for operation at certain speeds and levels. There are efficient humidifiers you can purchase that don’t waste water and they will give you exactly what you need.


Some types of humidifiers require ventilation of hot air for operation. Make sure you know how your new humidifier installs and whether it requires ventilation outside your home. You may need to do home construction and modification for correct installation if that is the case.


Many humidifiers do multiple things aside from humidifying the air. Make sure you know whether the humidifier you purchase will require you to maintain and change filters for allergens and other airborne particles such as dust.

There are also special filters that can catch dust mites, pollen, and viruses, so if you need to add features like that to your home, you can be prepared.

Energy-Saving Features

Saving energy can help you save money and help protect the environment. In this matter, make sure you know the good and the bad about the humidifier you are looking to purchase. You don’t want to end up wasting water or pulling more energy in higher settings. Check carefully the information about how many volts the system draws. Automatic shutdowns can help your system save water and electricity.

Long term cost

Purchasing price is not the only thing you need to consider for your home humidifier. You need something that will cut down your other bills to make your purchase cost-effective for the long term.
