Less filter capacity

Less surface area due to number of folds and depth of filter. Not worth the money since it is NOT comparable to other quality filters.

Good filter, good price

My HVAC system was replaced last summer and I had to start buying filters which were much larger than my old ones. Filterbuy offered the right size for a very reasonable price. I'm now going to order more!
