Making the right decision when it comes to selecting an air filter for your home can be a challenging task. But with the right information, you can make an informed choice and ensure that your air filter fits properly and provides the best air quality for your home. The first step is to identify the size of the air filter you need. You can usually find this size on the side of the air filter you already have in use.
This size will be the nominal size, which means that it is rounded to its actual size. If you can't find the size of air filter you need at a local home improvement store, you may be able to locate it in your HVAC manual. It's essential to make sure that the air filter fits snugly into the air filter compartment, leaving some space around the edges. If the filter is too large, the frame will wrinkle, air flow will be restricted, and longevity will be compromised.
On the other hand, if it's too small, room will be left for debris and particles to enter. Once you know the required filter dimensions and the desired Minimum Efficiency Reporting Value (MERV) rating, it's time to pick out the type of air filter for your home. Fiberglass, polyester, washable, pleated and electrostatic filters offer different air filtering capabilities. In a home with average air quality, fiberglass filters should not be replaced more than once a month and pleated filters every 30 to 90 days. The Home Depot also offers a full range of air filter accessories, making it easy to keep the system running at peak performance. With all this information in hand, you can make an educated decision and choose an air filter that meets your needs.
