Food and Drug Administration (FDA) recommend air filters that can remove at least 99.97% of airborne allergens and pollutants, including mold spores and dust that are as small as 0.3 microns. To measure filter efficiency, experts use the Minimum Efficiency Reporting Value (MERV) rating system, which classifies filters based on their ability to capture particles. The rating ranges from 1 to 16, with 16 given to the types of air filters with the best filtering capacity. Fiberglass air filters are the cheapest on the market, but they are also the weakest option and are recommended only as “pre-filtration devices” by the National Air Filtration Association because of how ineffective they are.
Pleated filters consist of a medium fabric made of polyester or cotton, organized in pleats to increase the surface of the filter. These filters are slightly more expensive than fiberglass filters, but they are also more effective against pollutants and even capture smaller air pollutants, such as pollen, pet dander, and mold spores. UV light filters remove bacteria and viruses from the air, but they do little against contaminants such as dust. As a result, these filters are generally part of a more advanced filtration mechanism, such as HEPA filters.
One of the best air filters for household furnaces is the MERV 8 HVAC pleated AC furnace filter that will help you breathe healthy indoors. If you are looking for the best household air filters that are easy to install, you won't have any problems with Filtree. However, if the particulate load in the air increases due to having pets, leaving windows open, lighting candles frequently, or other activities, you may notice that the filter becomes more dirty and requires a quicker replacement. The Rheem indoor air filter is an economical option if you are only concerned about capturing large particles for the sake of the longevity of your HVAC system. On the other hand, if you want to improve indoor air quality, experts recommend media filters instead of other types of air conditioning filters.
The Honeywell Home pleated air filter is a 4-inch oven filter that is electrostatic and easy to install. It captures particles such as dust, dirt, and dander that would otherwise clog the oven or settle in ducts and lasts up to a year. When it comes to choosing an air filter for your home, there is a lot of controversy about air filters due to so many filtration options available. To make sure you get the right fit for your HVAC system, take out your current air filter and check the size printed on the frame. The industry standard is to use the Minimum Efficiency Report Value (MERV) air filter rating system.
