- MERV 7
- Premium Quality
- 10 pleats per foot (2")
- 25 - 30% efficiency
- MERV-7

- Proprietary Media - Assures Rated Efficiency
The heart of the product. Airguard medias are manufactured to exclusive specifications produced only for Airguard. Nobody pays more attention
to media specifications than Airguard. Rigid requirements for resistance, efficiency, MERV values and dust holding capacity are verified by
QC checks on incoming raw materials, production line sampling and field audits of finished goods.

- All DP filters are designed with a consistent pleat shape on
predetermined centers causing dirt to collect evenly over the entire
surface of the media. Fully utilizing every square inch results in a
slow steady rise in resistance for maximum dust holding capacity.

- Consistent pleat alignment enhances dust holding capacity for longer service life.

- Galvanized Steel Pleat Support - The Airguard expanded metal pleat support grid is made of galvanized steel for maximum rust resistance. The metal grid maintains pleat shape and prevents fluttering in operation.

- Two Piece Frame Construction - Double wall thickness around the outer edge and integral die cut cross members provide strength and rigidity.
DP filters will not rack, warp or bend under normal handling or operating conditions.

- Heavy Duty Beverage Board Frame - Moisture resistant, sturdy frame material stands up to rough handling, difficult service conditions, long service life.

- Water Repellent Adhesive - The adhesive used to bond the frame and media pack into a unitized assembly is highly water repellent. The pleats hold together even when wet. No delaminating, no excessive buckling, no collapsing.

        These filters are use in my Geo Thermal Heat pump and they work very good. My wife says she never sees any dust on the furniture anymore. I will be ordering again when I need more filters.

            This is my second order of these filters. When I had my furnace replaced, the installer recommended these thick filters. He said they sold them for [$] each, but I could get them at local home improvement mega-marts. Not the case and [$]is way too much. I tried the thin filters, but they restricted the air flow so much, after ~3 weeks my system couldn't hold temperature and I had to replace them. I was happy to find these filters at a reasonable price. I've been changing them every ~3 months with no decrease in system efficiency.

                Filter chamber of the Air Handling Unit was redesigned to accommodate the 20x20x4 filter to seal against carbon monoxide infiltration for garage application.
                To help with the removal of the filter, I add adhesive tape to sides in aiding removal of filter.

                  Comments about Airguard Air Guard 20" X 20" X 4" DP-40 Max Pleated Filter:

                  I had my air handler replaced and the crooks that did it talked me into a thick filter. The one that came with the install worked fine, but when I tried to replace it, I couldn't find any local suppliers except the installer, who would gladly replace it for $50/filter. Yeah, right.
                  I learned three things about these filters: 1) If the HVAC in you house is not designed for a high MERV filter, don't get one. The system, can't handle that level of air resistance. 2) The furnace filter is meant to keep the furnace clean, not the air in your house. 3) If you use a high MERV filter, expect your furnace efficiency to drop dramatically. I learned I had to use a cheapie MERV 0 (well, maybe not that low) filter in winter otherwise my house couldn't stay warm!
                  So I was glad to find these filters with a lower (7) MERV rating and at a reasonable price. I hope I can get by with changing them every 3 or 4 months. If not, it's back to 1" cheapies.
