Review on 🌬️ Nordic Pure 14X20X1 Pleated Air Filter - Superior Performance and Durability by David Romo

They worked but not as well as they should. I bought the 14x20x1 size thinking it was the same size as other brands with the size listed. The website lists 'actual dimensions' as 13.5 x 19.5 x 0.75 and I thought it matched other brands. I was wrong. The 3M Filtrete brand filters fit my oven slots perfectly, these Nordic Pure brands were half an inch smaller on all sides and I had to get creative to make sure they seal well enough for the job. They did well, but a bad landing definitely reduced their effectiveness. When considering these filters, be sure to check the "actual dimensions" and measure the physical slot for your filters at home to make sure they match. They're a great price and seem to filter the air well, but I won't be buying them again due to the fit.
