AIRTEVA Filters are the next generation in air filtration, they are unlike anything you've seen in stores.

Once installed, this air purifying system will transform the quality of the air you breathe. We guarantee you will love this air filter.

You'll receive the patented AIRTEVA air filter frame. This permanent, 100% aluminum frame features a unique Leak-Guard Seal to eliminate bypass. To enhance performance, we have incorporated an electrostatically-charged screen into the frame. We'll make your new frame the exact size that you need to ensure that you will always have air filters that fit perfectly! You won't need to make any modifications to your existing equipment, it fits all makes and models.


Your frame includes a supply of BioPleat filter refill(s).
BioPleat is an extended surface filter media produced from a high quality blend of natural and man-made fibers. BioPleat utilizes mechanical filtration to effectively capture airborne particles. This air filter combines superior air filtration with low pressure drop for maximum efficiency.

leak guard seal

To ensure that all the air and pollutants go through your air filter and not around it, AIRTEVA Filters feature a patented Leak-Guard Seal. When your air conditioner or furnace turns on, the difference in pressure causes an airtight seal. No bypass means you're filtering 100% of the air. That means the harmful particles get trapped in the air filter, rather than in the lungs of you and your family.

odor control

carbon filter

How do Activated Carbon filters remove odors?

Activated Carbon filters have the ability to capture gas molecules and hold them. The Activated Carbon filter surface is made up of millions of tiny pores, the gas and odors fall into these pores and are trapped there until the air filter is disposed.
A single Activated Carbon filter has a flattened surface area of a football field.

zeolite air filter

How do Zeolite air filters remove odors?

A three dimensional, micro-porous natural earth mineral, thermally bonded to polyester. Zeolite has the ability to remove Volatile Organic Compounds (V.O.C.) and gases. They are trapped in the void porous cavities in the filter. It is especially useful in removing Ammonia and ammonium compound odors such as pet odors and urine odors.

Choose a Frame that Works for You.We hand make your permanent custom sized frame of sturdy aluminum and a permanently attached electrostatically charged screen. They won't bend, melt or warp like plastic or cardboard furnace filters. All filter frames are backed by An industry - leading 10 year warranty!

This unique 100% aluminum air filter frame, utilizes 4 hinges on the front of the frame. Opening the hinges allows you to place the filter media into the frame. When you close the hinges they lock, securing the air filter media. The Hinge frame makes using pleated filter media quick and simple.


The Snap filter system utilizes a two part frame. The two frame halves are held together by 8-12 neodymium magnets. To replace filters, just pull the frame apart. It’s so simple! As an added bonus, for systems that use multiple filters, Snap filter frames will cling to adjacent Snap frames, eliminating air bypass.

I bought a house and the panel on the HVAC unit said it used a 16x20 filter, but it was almost an inch to small all around and had to much bypass. I couldn't find a filter that fit properly until I ordered a 16-3/8 x 20-1/2 from here, and it fits perfectly.

Filter system
Even the manufacturer stopped making filters to fit factory air return, never had an acceptable selection of grades anyway. Provided dimensional needs to Filter Factory and custom made frame and replacements delivered within a week. Much better quality than any product I had purchased in the past. Have no regrets on initial investment and will likely be less expensive in the long run anyway. Happy to recommend this product to anyone looking for something that fits and works as it should.

Spending $50,000 when AC failed and mold took over in my Florida condo. I highly recommend calling Alissa to learn which filter is best to fit your need. Her advise was excellent and I'm ordering a similar filter to meet different needs in my Virginia home.

So far, so good
We live on a gravel road so I suspect we'll really test these filters this spring and summer. So far, though, I've found ordering and installation to be accurate and easy, respectively. I like the construction of the frame and filter media. Given what I've seen thus far, I'm optimistic about the performance of the HealthSmart AC filter system that I've installed.

I have used these filters for about ten years and find them to be of excellent quality and provide excellent filtration. They arrive promptly and undamaged due to their packaging. I would recommend them to anyone who is looking for filtration that lasts longer and does an excellent job.

Been using for years!
We've been using these custom filters for years no - no problems at all. For us, they do last 3 months each (4/year). Seem to keep our A/C running just fine - no complaints!

Year Round A/C required
I have been using these filters since I had my Trane A/C installed about 10 years ago. Since South Florida requires cooling almost the entire year I have found these to be the best filter for the climate. They do an excellent job of trapping dust and allergens. Filter Factory does a great job in filling your order and shipping it in a timely manner.

Works heaps better than the Filtrete!
When we had the duct work replaced in the house, the contractor put in the HealthSmart frame and filter. It works heaps better than the Filtrete furnace filters we were using before. And I really appreciate the fact that I can get odor controlling pads to go with my filters as well (with three kids - one in diapers, and four pets - one a very old lady of a boxer, it can get kind of stinky in here)
