I have Nordic Pure 14x30x1 filters as I need the fastest possible filtration speed and MERV 14 is the best I can find. I used to buy 3m Filtrete 2100 filters but nowadays they are almost impossible to buy. The filters appear to be high quality, dense fibre, well made etc, but typically the 14 x 30 x 1 dimensions should be slightly smaller than the hole they fit. in (and they claim they are) but they're definitely a little over 3m so they were tricky to install, basically had to pinch the edges and bend the filter to get them in. Eventually I was able to fit them and they seem to filter better than the top 3m. A star was deducted for that and also for the box being twice the size of the filters which is really a waste.
