The first batch of 3 filters were very slanted and unusable. You sent me a second batch which is almost as bad. Is there any quality control? Also the media which traps the dist is much thinner than the one i was replacing.
when I started with you. your 20X24X1 used to fit perfectly. then the last two prior to me cutting off .5 inch to small now. I give up. help?????? maybe 20X23.5 X1
These are wonderful and they work great. I have asthma and my husband puts the filters in for me. If you have asthma, this is what you need. Thank you.
