Review on 🌬️ Nordic Pure 18x20x1M8 6-Pleated Furnace Air Filter by Tyler Owens

I bought a whole box of these filters and they get half an inch smaller on both sides and 0.75 inch deep instead of an inch. This causes the filter to rise every time you turn it on, lifting the filter and pulling it up tight. Obviously, it lands awkwardly when switched off and falls through. When I installed it it seemed small, but I had no idea it was so small it could fall out. I ordered and used the size indicated on the device. Never had a problem with other filters but this one really bites me. It must have fallen out shortly after installation because when I went to change it yesterday I noticed the fall. I put it back in because it looked clean and fell out again today. I went under the device, looked at the vents, and my vents were covered in dust and even some kind of mold. I had a double lung transplant and mold is the last thing I need. I am very angry with this company. I have had pneumonia for two months and am currently on intravenous antibiotics at home.
