Review on 🌬️ Efficient Air Filtration with Nordic Pure 18X24X1 Pleated Filter by Mike Carter

I spent over $80 on two six packs of these filters and found them to be too small. Since I only discovered this after the return window had closed, I forfeited that money. Revain says there's nothing they can do. I called Nordic Pure and they told me to call Revain because they sold the filters. A representative from Nordic Pure told me that the size on the packaging is the "nominal size" and NOT the ACTUAL size, which is written in small letters on the filter itself. She said this is an industry standard that all filter manufacturers use, but they all use different actual sizes. The only advice the rep would give is to either use styrofoam tape to seal the gap or sell the filters on ebay or a flea market.
