There is a difference between permanent filters and washable filters. Washable filters can be washed with water and soap, while the other needs to be vacuumed. 

Washable Filter Cleaning Process

The cleaning process is simple and is not complicated at all. First, just unplug the Air Purifier and remove its filter. Then see if you want to wash it or vacuum it. If you want to wash it then use a cloth, warm water and soap. After washing, dry the filter before putting it into the air purifier. If you are owning a vacuum filter, use the brush attachment to clean it. The outlets and the air vents should be cleaned properly. 

What is the Lifespan of an Air Purifier with Washable Filter?

The longevity depends on various factors like how you maintain it, clean it and how polluted your air is. It is wise to have an air purifier with at least two filters so that the pre-filter protects the other filter and extends its lifetime. Usually, an air purifier with washable filters lasts easily for around five years. 

 How much does it cost?
