Experts recommend a permanent electrostatic filter with a rating of MERV 8 and microns 1 for those with allergies. This kind of filter captures particles in the air with self-charging fibers. They can also catch smaller contaminants without getting dirty too quickly. These filters have washable versions, but when you clean them, be sure that they’re completely dry before placing them back where they go. 

The importance of changing air filters in your home is something that many people tend to underestimate. Air filters are either disposable or reusable, and you’ll need to replace or clean them every one to three months. They’ll aid in improving the efficiency of your heating and cooling system as well as your indoor air quality. If someone in your household suffers from allergies or asthma, you want to be sure to replace or clean them regularly. 

While air filters are one of the most vital components of your heating and cooling system, they’re often overlooked. They often look like a large cardboard box, and are usually made of a spun fiberglass material framed in a cardboard frame. Air filters can also be made from cloth or pleated paper.
