Just installed , time will tell if the price is right or not . Little pricey but so far quality seems to be good and service was ok.

The filter is smaller than a 3M Filtrete and does not fit well in the vent.

BUYER BEWARE: NOMINAL SIZES MAY BE SMALLER THAN ACTUAL
on October 24, 2024
Posted by: Anonymous
I get there are nominal sizes and then actual sizes, but in what world would you list a nominal size that is SMALLER than actual? If it's too big, it won't fit! Apparently 17x21 really means 17.5x23! 23! That is way off! Why offer this size if you don't actually make it?
