The air filter you use for your heating and air-conditioning system has two important functions, according to the National Air Filtration Association (NAFA). In a normal comfort air-conditioning system, the filter helps to:
1) protect the mechanical equipment
2) provide the degree of cleanliness required for normal occupancy and space usage.
Some of the airborne particulate contaminants which may be present indoors include dust, pollen, mold spores, pet dander and residue from building materials and household products.

True, there are many other air filters on the market. But a close inspection of other filters will reveal that some of these air filters rely on some type of foam or porous pad as their primary filtering media. Even though they may show specifications that seem impressive, foams may become infused or impregnated with particles and become hard to clean, as well as deteriorate over the years. This could lead to restricted air flow and potentially harmful additional stress on your unit.

But the A+2000 is made of space-age synthetic materials and N) FOAM, allowing it to be effectively cleaned and reused indefinitely. Its stage-loading configuration allows it to be easily cleaned with simple backwashing (reverse direction of air flow) with cold water. Because it can be cleaned effectively and will not corrode, degrade or deteriorate, it is truly your Filter for Life!

If you've been holding your breath waiting for a quality, dependable air filter, now is the time to make a move and get the A+2000 Permanent Air Filter. Simply stated, the A+2000 gives you the quality you and your family deserve.

With the A+2000, you'll enjoy the comfort of knowing your A+2000 Permanent Air Filter is your Filter for Life. Because of quality construction and superior design, we are proud to offer a Full Warranty* for the life time of the original purchaser. Ask your dealer for a copy of our warranty.

Layer E (Back)
Fine material, tightly woven and made of high density polypropylene. This final layer provides more stage loading to help the filter capture some particles as small as .5 to .6 microns.
Layer D
Medium mesh peak and valley design containing material made of high density polypropylene. This is the third layer of filtration material designed to hold particles in valleys allowing air flow through peak areas.
Layer C
Eggcrate design made of polystyrene material. The physical properties of this glass-like material are its strength, stability and electrostatic holding capabilities.

Layer B
This patented first layer has a proprietary peak and valley design with large openings to allow maximum air flow with filtering capabilities to capture larger particles. Made of high density polypropylene, this layer starts the electrostatic reaction that holds particles to the fabric.
Layer A (First)
Polyethylene webbing designed to hold fabrics in framing under high velocities of air flow.
Framing
High density polystyrene designed for strength and durability. Physical properties: Non-corrosive and non-conducting.
