Review on 🔍 Enhanced Performance Aprilaire 510 Replacement Filter by Paul Dahl

I ordered this replacement filter over a month ago so it cannot be returned or refunded. The item I received was an AprilAire 501. I just came out of a 90+ degree attic to install it and found out I had the wrong filter. I assumed I made a mistake and ordered the wrong one, so I ordered the correct filter for the AprilAire 510. When I saw the "Buy again for AprilAire 510" message, I wondered if I had made that mistake or if Revain had supplied the wrong filter. It turned out to be an Amazon. My records show that I have purchased 5 or more of the 510 filters including the last one. Having previously purchased a head thermometer which was only used for 2 events but was purchased more than 30 days before I reported it to Revain I can only assume they will refuse a replacement request for this product as well.
