This or That — HVAC Edition: Here’s the Difference Between an Air Purifier and Air Scrubber


The quality of the air we breathe has been important for years, but because many of us are spending more time at home due to the coronavirus pandemic, our home’s indoor air quality is more important than ever. Although both an air purifier and air scrubber can provide clean air, just like other HVAC equipment, knowing how they’re different and figuring out which is best for YOUR home is key. The clean air experts at Clay’s Climate Control are here to break down the difference between an air purifier and air scrubber, so you can make the best choice for you and your home!

What an Air Purifier Is

Air purifiers are devices that provide clean air by removing dust, pollen, allergens, and other contaminants from the air. Because an air purifier is equipped with ionization capabilities and a fiber filter that’s electrically charged, these devices capture polluted air, kill the contaminants in it and then release clean air into your home. Having a whole-house air purifier installed into the ductwork in your home is an easy way to improve your home’s indoor air quality. Stop breathing in contaminants — which can cause a variety of health issues, such as coughing, congestion, nose bleeds, headaches, and dry eyes — and start breathing in clean, healthy air!

What an Air Scrubber Is

Similar to air purifiers, air scrubbers also have an ion feature and they are also installed into a home’s ductwork. However, air scrubbers provide clean air differently. Air scrubbers constantly put out negative ions, and as air moves through ductwork, these negatives ions detect contaminants in the air — which are positive ions — and combine with them, forming a heavy particle that is unable to float. When the air turns on again, these heavy particles will blow through the ductwork and get captured in your air filters, leaving your home with better indoor air quality.

How to Know If Your Home Needs an Air Purifier or an Air Scrubber

If you’re looking to change your home’s indoor air quality standards, both an air purifier and air scrubber can help you do so. In fact, both of these devices will improve indoor air quality because they are able to remove up to 99% of air pollutants. Homeowners who like the idea of a device capturing contaminated air inside of itself and producing clean air should go with an air purifier. However, it’s important to note that air purifiers require maintenance, so expect to change its filters every few months. Homeowners who prefer minimal maintenance and would like both their air AND their surfaces clean should opt for an air scrubber. Just remember that air scrubbers do not clean the air within their device but instead clean the air in your space, so just make sure everyone in your home is comfortable with that.
