Why Are We Different? How Often Should I Change My AC Filters? What Filter Should I Buy?
Since 1995, we have been manufacturing the highest quality pleated air filters at our facility in San Antonio, Texas, USA. The air you breathe is our priority. When you buy filters from us, you get the best product available made by people who really care about quality — and clean air! The answer to this depends on your unique situation. Here are some variables to consider: if you live in an extremely hot climate where your AC is constantly running, filters ought to be changed once a month. In moderately warm climates, you can stretch that to two months. If your AC sits idle half the time, then every three months could make sense.

Another important factor to consider is the level of airborne allergens in your area. Allergens can come in from the outside — think dirt, dust, mold, pollen — or they might already be in the home — think family pets, dust mites, roaches, mice, mold. Also, think about things that are not allergens, but that can trigger attacks — cigarette or cigar smoke, wood smoke, sawdust, chemical sprays, perfumes. If you have any of the situations noted above, consider a more frequent filter replacement cycle.
Each filter has a MERV (minimum efficiency reporting value) rating. Residential ratings run from a high of 13 to a low of 1. The higher the number, the better the filtration. We offer you MERV 10, which is usually found in standard commercial buildings and better residences, and MERV 13, which is used in superior residential and superior commercial buildings.
