3. Washable Filters
Washable air filters are environmentally friendly. Unlike other disposable air filters, washable can save money as you can wash and reuse them later. Since you can use them multiple times, the price is typically higher than many other filter types.

However, they could be more effective in screening against dust and dirt. They are also ineffective in eliminating gases, fumes, and smoke from your house.

Media filters are famous for low maintenance requirements, as they need to be replaced only twice or thrice a year. The excellent filtration system of media filters helps in capturing air pollutants. These filters are easy to maintain, but they need to be professionally installed.
