Review on 20x20x1 Reusable Furnace Filter for Home by Bradley Wacks

9/19/20 - Two filters installed, ordered today. I needed the perfect air handler gasket, so I added a 3/4" x 5/16" Frost King foam rubber gasket. I'm not sure what effect MERV 11 filters will have on fan motor airflow restrictions over time since that information is unavailable, but we'll see. Right off the bat the build quality is great, I used WEB MERV 8 reusable filters and you can literally see through the filter if you hold it up to a light, you can't see through a K&N filter. The frame is made of plastic, but is much more rigid than the WEB filter. I will update the product specification information regularly. A little hint: The filter size 20x20x1 is actually 19.5x19.5x1. The 20 x 30 x 1 filter size is actually 19.5 x 29.5 x 1.10/2/20. Update: There are no air restriction issues or signs of the fan motor struggling for MERV11. I just ordered another set of filters to replace immediately while I clean the first set.
