If I Have Air Filters, Do I Need an Air Purifier As Well?

pleated-air-filterYou’re concerned about the indoor air quality of your home. Many people are right now, since we’re spending much more time indoors and the summer won’t change that. So along with a reliable air conditioning system (which we can help you with), you’ll also want to know you have clean and healthy air to breathe indoors.

But are the filters you have in place enough? And by this we mean special air filtration systems, not the basic filter on the HVAC cabinet, which isn’t designed to clean the air. The right filters can do a fantastic job removing major air pollutants from circulating in a house. But they sometimes need help from air purifiers. Let’s take a look at air purifiers in Cary, NC and when they’re useful.

When Filter Strength Is Too High

The strength of indoor air quality filters is measured as MERV, minimum efficiency reporting value. The higher the MERV rating, the smaller particles the filter traps. Special high-MERV filters are used in hospitals and computer clean rooms to filter out minute contaminants. However, these filters will ruin a home’s HVAC system because they won’t let air through either. If you have professionals install the filters, they’ll know the maximum MERV the HVAC system can handle … and it may not be strong enough to stop some of the smaller pollutants in your house.

In these cases, an air purifier is invaluable. You wouldn’t want the purifier to take on the cleaning job on its own, but for trapping small pollutants that make it through the mechanical filter, they’re ideal. The right teaming of filters and purifiers can eliminate more than 99% of unwanted airborne pollutants.

Stopping Odors

Standard air filters are often ineffective at reducing odors in a house from a range of sources. Odor molecules are tough to trap in filter mesh, and filters can themselves become sources of odors if too much gets trapped in them. Many air purifiers deal directly with odor molecules, helping to create a more pleasant living environment.

Targeting Mold Spores, Germs, Viruses, Bacteria, and Microbes

This is a whole range of “nasties” that nobody wants inside their home, and people are more worried than ever today. Strong HEPA filters can stop many of these organic pollutants—but HEPA filters are rarely appropriate for residential HVAC systems.

We recommend using a UV air purifier in conjunction with your filters to deal with these pollutants. UV air purifiers destroy the cellular function of organic pollutants, either killing them or rendering them inert. And they do it without any chemicals.
