Bests & Worsts Reviews from Amazon

I order a box of filters at a time. So, with only a couple filters left from my last purchase I ordered these, an upgrade to a MERV 11. Well, I went to use one and noted that the first one I pulled out of the box of 6 was crushed/mangled in the corner. I should have noticed this when it was delivered. But when I went to put another one in my vent, it did not fit. Most 20x20x1 filters are really more like 19.75 x 19.75 x.75 but this one is 19.5 x 19.5 x .75 and it means I have a one inch gap to fill on two sides when I insert it. Not happy. My window to return this was 5 days ago apparently.
