Purolator serva-cell ashrae rated hvac filter 20X20X6
This is for one new Purolator Serva-Cell filter. Filter size is 20x20x6.
These filters are roughly comparable to Hepa filters as 85% effective. Where a Hepa is 99.97% effective. However, Hepa filters are tested differently and do not have a MERV rating. Roughly, a Hepa would stop 50% for particles than this filter. Other factos must be considered such as air flow. Please see link for more details about this.
