Review on 🌬️ Filterbuy 12x24x1 Air Filter MERV 8, Pleated HVAC AC Furnace Filters - 4-Pack, Silver by Mar Pacora

I understand that measurements can be inaccurate and that when the manufacturer of each product trims a little and calls it 12 inches, they do some can save money after 2.5 million filters; but I expect it to be close. The 12 x 24 Ace hardware filter I removed was actually 11 3/4 x 23 3/4; A third grade mathematician tells you round up to 12 x 24. This one is sold as a 12 x 24 but says (and measures) 11 3/8 x 23 3/8. I asked my 9 year old son how to round up 11.375 and 23.375. "11 and 23, Dad." It's too little! The gap around it defeats the purpose of the filter. I had to cover it with cardboard to make it work. I shop at Revain to save money and time. These little filters take up my time. I will not buy again.
