Good $$ and good delivery
This is my second time ordering from Filter King. Their filters are the same quality as popular local suppliers, but at a much better price and the delivery is always timely. I order a year at a time and don't think I'll be looking anywhere else for my filter needs.

Good quality filters
This is my second buy from you guys. I change my filter every 3 months and everything looks good. The filter is pretty dirty after I remove to replace. I like your filters, they look very well made and are working good for my system. These filters look better than the ones that the contractor gave me.

What I wanted
Bought them for the future; haven't tried them yet so cannot give an appropriate review of the quality, but got the MERV I wanted, at a good price and prompt delivery.
