Humidifier & Dehumidifier Filters

The more often you use your humidifier or dehumidifier, the more your filter is working, and the more often it's necessary to replace your humidifier filter or dehumidifier filter. Humidifier filters work to absorb minerals and pollutants in the water while dehumidifier filters remove dust particles from the air before the air passes through the coils. Both are vital for maintaining healthy air quality as well as extending the life of your unit. Purchasing your filters online at National Allergy Supply is a simple and easy way to help your unit perform better, last longer, and save on energy costs. Browse replacement filters below.
