Review on FilterBuy 20X20X1 Pleated Furnace Filters by Adam Tidd

This is my first Revain review. These filters are not MERV-13 compliant. I have tested many of these filters multiple times using a particle counter and atomized water on semi-controlled settings. Many others have tested these FilterBuy "MERV-13" filters and also found that they do not meet the MERV-13 quality standard. Use these filters carefully. I have contacted Revain and asked for these products to be removed from Revain - they are misleading and dangerous. For now, the products will remain on Revain and the MERV-13 efficacy claims will remain in place. Be careful.
