Great Filter- Fits and #1 Quality

At last! A filter that actually fits my 20x20 inch filter holder! Many vendors sell 19-1/2x19-1/2 inch filters that just fall through. PLUS the pleats are evenly spaced and the product well built. Thumbs up!

Easy to install. Easy to

Easy to install. Easy to replace. One large filter, in my system at least, works better than a thinner one.
