Nothing for me to review because I made a big mistake. I ordered the 18x24x2 instead of 18x24x1. And now I can’t use them

The filters do not fit. Actually measurements are smaller than described size in every dimension. Less substantial than the honeywell filters I was replacing.

This filter purchase was so problem free and cost effective I can only recommend this as a very positive experience and for anyone purchasing for multiple locations this is an A option.
