Review on 🔍 Highly Efficient Pleated Furnace Filters - FilterBuy 20X24X1 by Richard Miller

The filter I ordered should be 1x20x24. The actual size is 3/4 x 19.5 x 23.5, which is too small for my device's filter hole. It lets air flow around it and wiggles back and forth every time the fan turns on. I didn't keep the original packaging so I can't return it without purchasing a new shipping box. This is my fault and the $30 tutorial. Now I use tape to hold the filter in place and prevent air from getting past the filter. Buy at your own risk but I will not buy again and will not advise anyone.
