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.

Filters4Air news

The nose knows

The nose knows

Air filters can do more than keep the air inside fresh. Besides eliminating (or significantly reducing) airborne allergens like mold, dust, and pet dander, good-quality carbon/charcoal filters can actually remove odors from the air. 

If you've flooded and are rebuilding, or if you're just overwhelmed by odors - think dirty laundry, cooking "aromas," pet odors, mildewy stink - charcoal really makes a difference. Its porous surface absorbs all of those smells. Instead of covering odors up with sprays and other scents, charcoal actually gets rid of them.

Recently we shipped several boxes of charcoal filters to a very good restaurant in Houston that happens to live right under some very lovely apartments. Needless to say, while residents liked the idea of going downstairs for a great steak, they didn't want their home to smell like day-old dinner come morning. Charcoal to the rescue. 

Charcoal filters work the same way as standard air filters, only they're black. Pop them in where you'd normally replace your filters when you're ready to clear the air of smelliness.
