When it comes to finding the best reusable HVAC air filter, the K&N lifetime filter is a top choice. This popular filter has a solid frame and a powerful filtration plate that can effectively prevent dirt, lint, pet hair, and smoke from circulating around the house. Another great option is the Trophy Air HVAC oven air filter, which has an impressive 95% absorption rate of air particles. This self-charging electrostatic filter requires no additional energy and has a MERV rating of 8.It is lightweight and durable, and comes with an installation guide and a long-term warranty.
The Filtrete 20x25x1 AC oven air filter is also of unbeatable quality and performance. It has a MERV rating of 8, making it more efficient than most other filters. Air-Care filters are made of 5 layers of filter material that have been certified by a third party, and they offer minimal air resistance while capturing large particles. Washable air filters can be constructed in a variety of ways, but the biggest difference is in the MERV classification.
The pleated filter design consists of a large surface area for air filtration and the entrapment of more particles suspended in the air. If the washable filter is poorly designed, it may only last a year or two and can even damage the air conditioning system. The MERV rating will tell you how many particles the filter can capture, and washable air filters range from MERV 5 to MERV 11 or more. The higher the MERV rating, the better the filter traps particles (but also reduces HVAC airflow).
If you're only concerned about capturing large particles to prolong the longevity of your air conditioning system, the affordable Rheem indoor air filter is an economical option. At MERV 13, it is the highest rating you'll find for most popular residential HVAC filter sizes. Adequate air circulation helps to reduce resistance to air circulation and, therefore, to control heating, ventilation and air conditioning pressure. When HVAC filters become dirty and clogged with debris, air can't flow freely through the ducts, making your home less comfortable and eventually can break HVAC equipment.
