What’s the Difference Between Air Filtration and Air Cleaning? 

It’s a mistake to assume that the standard air filter in your furnace, heat pump or air conditioner will guarantee clean and healthy indoor air.

Unless the air filter is rated as high-efficiency, the filter probably won’t capture anything but the largest dust particles. While this will protect sensitive HVAC components, it won’t do much to clean the air. This is a problem if anyone in your family suffers from allergies and other respiratory issues. Increasingly, households are considering a two-part strategy when it comes to ensuring indoor air quality – air filtration and air cleaning.

The Limits of Air Filtration

In a typical central heating or cooling system setup, a standard flat-panel filter fits into a slot between your home’s ductwork and the furnace, heat pump or A/C. Before air goes into the equipment to be heated or cooled, the filter, depending on its quality, removes some amount of particulates from the air. While certain air filters are designed to remove the vast majority of airborne contaminants, this comes with a negative consequence.

The same thing that makes the highest-efficiency air filters so effective at cleaning the air, dense filtration media, also slows the movement of air through the filter. Your central heating or cooling equipment will have to work harder to push air through the filter. This wastes energy, stresses parts, and may lead to breakdowns. It also can lead to poor air circulation in the home.

While most HVAC systems can be modified to accommodate a high-efficiency air filter, a whole-house air-cleaning system that works with your equipment may be preferable.

Consider an Air Cleaner

Several different technologies can be incorporated into modern air-cleaning systems, with the best models combining strategies to purify indoor air. A good system can remove up to 99 percent of the contaminants from indoor air. The more effective air-cleaning systems work with the home’s central HVAC system to treat all of the air that circulates through every room in the home.
