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.

Do I need to change filters in the winter?

Do I need to change filters in the winter?

 

It’s winter and if someone mentions air filters in a polite conversation most of us would be thinking, “Hey, it’s winter and I don’t have to worry about replacing my air-conditioning filters until summer.”

The truth is your home’s air filters take a beating in the winter. Some times worse than summer.

That’s because running your heater is running just like your air-conditioner in summer – and your air filter is working hard to keep the air you breath clean.

And winter air is NOT clean.

Think pollen, cedar, mold, dry grasses, dead and dried leaf dust plus the dust and dirt from the cold winter dirt. Kind of like that line from the movie Groundhog Day – “It's gonna be cold, it’s gonna be grey, and it's gonna last you for the rest of your life.”

Truthfully, it’ll only last until you change that filthy air filter!

Don’t trust me? I have a science experiment for you.

You know what our weather is like around here. 45 degrees one day, and you’re running the heater. Then 77 degrees, and you’re running the air-conditioning. Do this first — make sure you have a clean and new filter on hand. Then, after a month of running your system, pull that nasty filter out and compare the two.

Imagine you and your family are breathing the air coming out of that dirty filter. Yeah, not healthy. {insert harsh cough}

So, winter is here. Big deal – you still need to be buying air filters!
