It looked like a ordinary furnace filter to me, I would have expected a different type of filter, more in line like a hepa filter that was more densly configurate

They were undersized and did not fit properly in the filter slot. Compared to old and new 3M and Honeywell they are undersized! Would not buy again.

Fits perfectly and is durable and well constructed. My filters can be hard to find because of odd sizing but these are perfect. I will definitely be reordering!

The filters seem to be well constructed. The dimensions of the filters leave a half inch gap on 2 adjacent sides (length and width) as the stated dimensions are not the actual dimensions. To remedy this problem, a 3/4 inch wide by 1/2 inch thick weather stripping with a self-adhesive side is applied to these two sides. This adjustment makes the fit snug as it should be. All the returning air is then filtered without bypassing the filter through the gap. When the used filter is changed out, the weather stripping is gently removed from the used filter and then reinstalled to the new one. Works great.
