What’s the Difference Between Air Purifiers and Dehumidifiers?

AIr Purifier vs Dehumidifier in Littleton, CO

Air purifiers and dehumidifiers are often described in similar ways when marketed. They both benefit the home but have completely different functions that should be considered before purchasing either one.

Air Purifier

Air purifiers pull the air around your home through several filters that remove contaminants. These filters work like the filter on your furnace, essentially cleaning the air and improving the air quality on a smaller scale. They can remove dust, allergens, dander, and other particulates that may cause irritation and illness.


A dehumidifier lowers your home’s humidity level. Wet environments often have a lot of moisture in the air, which can lead to increased mold and mildew spores. Dehumidifiers remove the moisture from the air and collect it in a container inside that you can empty when it’s convenient for you. This appliance can remove harmful spores from the air but doesn’t filter the air or directly improve air quality.

Benefits of Using Both

Dehumidifiers and air purifiers are great additions to any home. If you have younger children or sick family members, an air purifier in their bedrooms could improve their ability to breathe and relieve congestion and irritation. Dehumidifiers are great for basements to keep the air dry and avoid damage to electronics, carpets, and other belongings. Make the best decision for your household based on your air quality and health needs.
