Review on 📦 Packaging for Honeywell FC100A1037 Filter Media by Hector Liamsi

All 20 x 25 x 4 inch filters have slightly different actual sizes. every dimension. These are the closest to the actual sizes you will find. The specifications listed on Revain's product description page (‎19.9 x 4.3 x 24.7) are correct. These fit my block much better. The AC company that installed the unit installed Floglas filters, which are smaller in every way. They fit as snugly as possible without snagging during installation. In short, they are perfect for my application. I'm glad I got them.
