One thing every property using an HVAC system needs is a high quality furnace filter. The utilization of quality furnace filters has been proven to extend the life of most HVAC systems, as well as improve the overall quality of indoor air.

The 16 x 20 x 1" filter design comes in a large variety of sizes and MERV Ratings. This model even touts a washable furnace filter with a MERV rating of 5. The other varieties are a MERV 4, MERV 8, MERV 11 and MERV 13 variety. These great filters are compact and prevent a number of different airborne particles from entering the living space. In addition, the MERV 5 washable discount filter gives you a greener approach to maintaining clean air. Instead of throwing it out after three months and having it take up space in a landfill, you only need to remove it, wash it, and replace it back into your HVAC system.

All of these varieties of discount filters will trap lint and dust, dust mite debris and pollen, but as the MERV rating increases, they may also trap mold spores, auto emissions, smoke, pet dander bacteria and tobacco smoke. Each model can be purchased individually or in bulk, and can be shipped free of charge on both outgoing orders and return shipping. These discount filters were built to last, and in that increased lifespan will save the homeowner money by not having to replace these furnace filters as often.
