The Merv 11 Air-T-Rex™ Universal Replacement Filter is a Real Game Changer

The Air-T-Rex™ Universal is a Merv 11 filter. This means it will catch 95% of particles as small as 3-micron plus 75% of one-micron particles. This is considered hospital laboratory-grade filtration. To achieve this superior level of filtration, the Air-T-Rex™ works differently than common pleated filters. Thanks to its ‘Depth-Loading’ technology, the Air-T-Rex outperforms traditional pleated filters It also offers a longer service life.

The purpose of any air filter is to let the maximum quantity of air pass through the filter while holding back the most-significant amount of micro-particles. Until now, to be effective, a standard air filter had to be tightly weaved. But, tightly weaved filters easily clog at the surface as you can see in the video below. In the end, a clogged filter doesn't work and dust starts to build-up again in your house...





The Air-T-Rex™ Depth-Loading filter is NOT easily clogged because particles penetrate deeper into its loosely weaved filter media. They become prisoner of a polymeric adhesive trap.


Tightly woven air filters are easily clogged. This means less ventilation, more dust on your furniture, an increase in energy costs and higher replacement costs.

The secret: Three levels of defence

Yes, the Air-T-Rex™ has three filtration levels. Unlike standard filters that are enclosed in a rigid cardboard frame, the filtering material of the Air-T-Rex is thermally fused around a galvanized wire ring.

Bypass unfiltered air resolved: This is a huge undetected and costly problem in most HVAC systems. Cardboard-framed filters do not seal at the perimeter thus allowing unfiltered air through. The Air-T-Rex is self-sealing. For a perfect seal around the perimeter, the filtering material has a flexible fringe of about one inch that exceeds the galvanized steel frame.



The first line of defence is provided by the synthetic filter fibers. From coarse to fine, they catches particles such as:

•  Mold
•  Spores
•  Spray paint and lacquers
•  Dust
•  Powders and flours
•  Fibre (fabric and carpet)
•  Pollen
•  Sawdust

The second line of defence is an exclusive particle-catching treatment (a polymeric-based adhesive) that works in synergy with the filter media to trap particles up to 40 times smaller than a human hair. This includes micro-particles like:

•  Anthrax
•  Legionella
•  Auto emissions

The third line of defence is a unique antibacterial treatment that eradicates microbials, molds and mildew and ensures a fresh and continuous healthy environment.

Cardboard-framed filters are vulnerable to the effects of moisture. Moisture can cause premature filter failure when the frame becomes wet and buckles under the pressure of the system (as pictured at right). If the filter remains wet and conditions are correct, mold and other microbials can easily grow. Since the Air-T-Rex™ uses no cardboard but relies on an internal wire ring for support and a proven antibacterial treatment, this creates a filter that is resistant to moisture/mold.

Should you consider an Air-T-Rex Premium + Carbon with an active carbon layer to control odours?

An Air-T-Rex™ Premium + Carbon (with an exclusive active carbon layer) is a good choice in neighborhoods near highways or where fireplaces or wood stoves are popular. In the house, an Air-T-Rex + Carbon will rapidly catch unwanted odors and gases.

The Air-T-Rex™ Premium + Carbon is a particularly good choice if you have an air exchanger and there are some outside odours or gases that you don't want get into the house.

Active carbon comes from a vegetal source. It should not be confused with mineral coal. It is a light black powder, constituted primarily of porous carbon matter. It is in fact a type of spongy charcoal with a very large surface area that gives it a very high 'adhesive' power.

The cavernous surface of active carbon is huge: one gram of active carbon has an equivalent adhesive surface of 2,500 to 25,000 square feet!

Active carbon has no taste, no odour, and no undesirable side effects. The spongy capacities of active carbon are used in a variety of applications. In addition to odour control, active carbon is used to filter water, white wines, and decaffeinated coffee. It is used to stock hydrogen and in the health care field it is used internally in cases of food intoxication.

It is easy to order

Unilike other brand name filters, the Air-T-Rex™ Universal is made to measure so it will fit perfectly into your HVAC unit. This removes the biggest problem for ordering replacement filters. You cannot be wrong.

Many people are confused by nominal dimensions, complex filter codes, furnace model and manufacturers' serial number and as a result they often order the wrong filter. This cannot happlen With the Air-T-Rex™. Just give us the real dimensions of your old filter and we will do the rest.

The Air-T-Rex™ Universal can easily fit any filter track (from 3/4" to 5"+ thickness) because it does not have a rigid cardboard frame. Its perimeter is flexible. Its thickness is 3/4 ". In this case smaller is better!

The Air-T-Rex™ Universal frees you from exaggerated 'brand name' prices: It is well known in the industry that furnace and air exchanger manufacturers sell their original filters at a high markup. They know that you are a captive client so they manufacture their filters with odd dimensions to be sure you cannot find them elsewhere. You don't need to be captive any more. You now have the opportunity to save a lot of money by ordering your garanteed-to-fit, made-to-measure, Air-T-Rex™ Universal Merv 11 filter right here!

The price will appear automatically after choosing the filter type and the dimensions. You can choose between the Basic Air-T-Rex or the Premium Air-T-Rex with a Carbon layer.

Shipping schedule

Depending on the distance, you should receive your custom Air-T-Rex™ filters between seven to ten working days after placing your order.

Tip for measuring in-between sizes

Example: If your old filter measures more than 15-1/2" but less than 15-5/8", order the smaller measurement (15-1/2" in this case). Don't worry; the flexible fringe around the perimeter will ensure a tight seal.

Tip for very large filters

If you aren't able to slide a very large filter into place because of the presence of a wall or other obstruction, divide its length by two and use two smaller filters to fill the space instead. The fringe will assure a tight seal between the two Air-T-Rex™.
