Alpha-Stat Filters
Attn: We are improving the air flow of these filters by adding more media. They will still have a MERV 12 rating, but lower pressure drop, so that will reduce static pressure in your HVAC system. Eventually all sizes will be improved, but for now only select sizes are available. Please contact us for details.

Alpha-Stat Filters come in many sizes. The Alpha-Stat's ability to capture submicron or breathable particles not only protects equipment but the fragile human lungs. Framed filters work well in in forced air furnaces, air conditioning systems, or anywhere a framed HVAC filter is required. Unframed media is excellent for use in window or wall type air conditioning units. Now rated at MERV 12 with low pressure drop, so you get the best air quality for your home, office, school, or hospital.  The electrostatic charge on the media, coupled with the mechanical filtration offers the best indoor air quality. Capable of removing dust, bacteria, mold, spores, mites, asbestos, smoke, pollen, and many other allergens. Any custom size available (minimum order of 12). Wide variety of sizes available.
Prices range from $11.30 to $27.00 depending on size & type, or if custom made. We offer a 10% discount on orders of 3 or more.
