It is essential to replace air filters regularly to ensure that they are able to remove bacteria and dirt from the air. This helps to maintain good indoor air quality and reduce energy costs. In industrial settings, air filters are used to preserve the quality of products and materials, as well as protect critical equipment from damage. The Home Depot uses the FPR rating system, while the industry standard is to use the Minimum Efficiency Reporting Value (MERV).Air filters become more efficient as particles form a layer on top of the filter medium, helping to filter out other particles.
Fiberglass, polyester, washable, pleated and electrostatic filters all offer different air filtering capabilities. Ultra-low Particle Air Filters (ULPA) can remove particles as small as 0.12 microns in diameter with an efficiency of at least 99.99%.Aluminum air filters are strong and durable and can be washed or cleaned and reused multiple times. MERV ratings range from 1 to 16, with higher ratings trapping small particles more effectively than lower ratings. Pleated air filters are made from flexible materials such as paper, polyester, fabric and cotton. Foam air filters are made from artificial porous foams made from polyurethane, polyether, polyester or a combination of these materials.
When using HVAC filters, it is recommended to use furnace filters with a MERV rating lower than 13 in residential spaces. The Home Depot also offers a full range of air filter accessories to keep systems running at peak performance. Subscription services make it easy to always have the best air filters for home use on hand.
