Review on 🔍 NaturalAire Pre Pleat 4 Inch Filter - 6 Pack for Enhanced Filtration by Tim Airy

A previous reviewer stated that the size of the filter is not quite 20" x 25" x 4". It is true. This filter measures 19.5 x 24.5 x 3.75 inches and fits my air conditioner perfectly. It seems that in the world of air conditioning filters, the size advertised is not the size you receive. I bought a 20x25x4 filter at one of the big hardware stores (blue logo or orange logo, make your own deductions) the 20x25x4 filters bought didn't fit my unit Last week when I was at the orange store I got their 20x25x4 filter measured and it was well over 20 x 25 x 4 (4.5 inches thick). The bottom line is you need to know the exact size of your device and then find the exact dimensions of the filter you are looking to buy. In fairness to the manufacturer, the exact size is printed on the filter, but the only photo on Revain didn't show this. I just uploaded a picture of this part of the filter to help our future buyers.
