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 High Performance Allergy (MERV 10), which is usually found in standard commercial buildings and better residences, and High Performance Allergy-Plus (MERV 13), which is used in superior residential and superior commercial buildings.

Who is Merv and why does he care about my air filters?

Who is Merv and why does he care about my air filters?

Good question.

Merv is not the name of a talk show host (if that goes over your head, you'll just have to Googlize it). Hint: think Griffin.

Actually, MERV stands for Minimum Efficiency Reporting Value, which is a rating system established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

Say that five times fast.

I know – “that, that, that, that, that.” Sorry I said anything.

MERV is designed to let you, the consumer, know the purpose for which the filter is intended.

This is a chart I “borrowed” from Wikipedia. Hey, I donate money to support them.

At Filters4Air we give you a choice – MERV-10, or what we call High Performance Allergy, and MERV-13, or what we call High Performance Allergy Plus.

If you start sneezing due to pollen, grasses, smoke or whatever – you need a new high-quality filter.

Hey – we sell high-quality filters. Who knew?

Anyway, we deliver right to your door. We also install, if you need help. Win-win.

Just go to our website and get your order in because winter is coming and that means your heater is on all the time, and that places as much strain or your air filters as air conditioning.

I mean, they are called “air filters” not “air conditioning filters.”

Just saying.

Aaargh, I hate that expression.

Hope you check us out at filters4air.com and thanks for the ear !!!
