We sell five product options of 14 x 30 x 1" furnace filters: MERV 4, MERV 8, MERV 11 and MERV 13, as well as a reusable washable filter that's rated MERV 5.

The pleated MERV 11 filter catches more pollen, dust and dirt than standard panel type HVAC filters. Its medium efficiency filtration protects expensive HVAC equipment from the effects of dirty air, significantly lowering your building maintenance costs.

Next is the fiberglass MERV 4 rated panel filter that comes in a 12-pack. This disposable panel filter has been engineered for affordability and performance. It can also be used as a pre-filter to extend the life of higher efficiency filters.

The MERV 8 pleated filter comes in a six-pack and typically lasts for about three months. Excellent for high velocity equipment, this affordable chemical-free filter is great for helping you reduce airborne allergens.

Another option is the MERV 13 rated pleated filter that's able to capture airborne allergens smaller than 1 micron. It features a moisture resistant double wall beverage board and has been rated as U.L. Class 2 by Underwriters Laboratories.

Finally, the permanent washable filter is rated MERV 5. It's easy to install and maintain and comes with a full warranty.
