Do I Need Air Filters AND an Air Purifier for My Home?


This is a question homeowners often ask us when they’re looking to improve the air quality in their homes. The answer depends on the house. It helps to explain the different jobs of air filters and air purifiers and how they can work together, which we’ll do in this post.

Air filtration and air purification isn’t an either/or proposition. Many homes use both, and the successful rate of particle capture and elimination depends on how well-selected and installed these devices are. It takes professionals to perform these jobs correctly, so when you’re interested in an air filter or air purifier in Berwyn, PA, call the Michall Daimion Heating & Air Conditioning team for the best assistance.

Air Filters Are a Good Starting Point

We advise our customers to first consider air filters. Air filtration systems can help almost any home. Filters work by trapping pollutants in various media, such as fiberglass mesh, as the air moves through the filter. 

Filters come in a range of strengths, with the strongest capable of trapping minute pollutants such as bacteria and chemicals. However, the stronger the filter, the more resistance it places on airflow; not all residential HVAC systems can handle these filters. The first step when you work with indoor air quality professionals is to find the maximum strength filter that will still allow your HVAC system to operate effectively and efficiently. A filter that’s too powerful can create comfort disasters in your home and even damage HVAC equipment.

Air Purifiers Provide Special Backup

Our team may find that the right air filtration system will do the job necessary for great indoor air quality on its own. But if there are still pollutants that can get through the strongest possible filter for your home, air purifiers are an excellent addition. 

You won’t want to have air purifiers alone for your home—these devices don’t do as well with trapping larger particles like dust and lint. They instead target the pollutants that often get past filters. These include microbes, volatile organic compounds (VOCs), chemicals, smoke, carbon monoxide, odor molecules, and mold spores. We’ll find the right type of purifier to target the specific airborne contaminants circulating through your home.

You Have Other Indoor Air Quality Options

Improving the air in your house doesn’t end with filters and purifiers. There are other methods that can help you enjoy the freshest and healthiest air for your family. 

One place we often focus on is the ductwork. Poor or leaky ductwork leads to inferior air circulation and allows more pollutants to enter the air moving through the HVAC system. There’s also the concern with high and low humidity, which can have a huge impact on indoor comfort and health conditions. We have ways to help counteract all these problems, so feel free to ask us for recommendations and other ways we can assist you so you have a home that’s an oasis of both comfort and healthy air.
