The descriptions of the different MERV numbers were very helpful in helping me select the right filter for my application. I also appreciate a discount for ordering more than one filter.Filterbuy has been very active in offering to assist with reminders to replace filters as well as with reorders.

I havent used this filter very long yet (~1 mo). So far its doing the job. I appreciate the sturdy frame around the filter that makes insertion smoother.

These filters seem to do the job. House ducts are clean which to me means the filters work.

A cost effective way to replace your furnace filter monthly reducing blower workload and maximizing air filtration. You basically can't go wrong.
