The product has less filtering material than it used to. Not sure how this affects the filters.

I can get my hard to find air filter. These filters usually last 3 months before having to change them out. There's a place to write the date for changing your filter and arrow showing you the right direction for air flow. The usually buy 6 at a time so, I always have my filters on hand. I do get a reminder it's time to buy more filters.

Works as advertised. It is made of paper and fiber so value is really difficult to rate. So, average with 3 stars.

One filter was coming apart when I opened the box, but other than that I am pleased with my purchase. It is a great price point for six filters and am glad they were in stock and shipped super fast!

Work great. Had a hard time finding the size I needed. Glad we found you. We recently ordered water filters for our KitchenAid refrigerator. Fit perfectly. Will be ordering other filters as I need them.

A great discovery for my odd size furnace filter at a very good price. The filter fits perfect & is a much better one than my old washable filter. Will definitely order more from Discount Filters.
