Review on 🌬️ Enhance Indoor Air Quality with Nordic Pure 10X20X1M8 6 Pleated Furnace Filter by Glen Needham

Very disappointed that these filters fit. They are at least 1/4 inch shorter in each dimension than the "filtrete" filters I substitute. These 10x20 filters are 9.5" x 19.5" while the filters I used are 9.75" x 19.75". , they don't fit snugly to the camera. My cameras are mounted in the ceiling, so every time the HVAC fan stops, they fall on the air vent. They're sucked back into place as the block rotates, but they barely seal around the perimeter. and make an annoying whistling noise when the return air flows around the filter.
