Airwash MultiPro Pleated Pre-filter MERV 8
The Pleated Pre-filter sized at 13"x13"x2" is included with the Airwash MultiPro Air Scrubber. This is a replacement. The pleats significantly increase the surface area the pre-filter has to contain particulate. As a MERV 8 filter it is a thick cotton polyester blend for holding large particles.
