"Ordered six-month supply of filters for our system at a great price and they arrived quickly and correctly. My wife was in the attic putting the new filter in when she yelled down that it didn't fit. Impossible I said. Took a quick trip up the ladder and sure enough I ordered the wrong size.

Got on the phone with Factory Direct and my problem was corrected that instant and the new filters arrived within the next day or two.

They are now our go-to site for filters. Highly recommended."

"Lowest price anywhere on the internet. Will buy from again."

"Received these quickly, have not installed one yet since I'm waiting for pollen season to start up in March or April. Hoping I notice a difference between these M13 and the current filters I have which are M11. "

"on time and great product at a great price.

"I have a unique size filter... No big box stores have then and the local HVAC supplier i typically get them from was out and wouldn't get any for 2 weeks or more. Plus I wanted MERV 8-11. Eureka I found what I wanted at a good price! Ordering was a snap and delivered to my house for free! :)) Thanks so much!"
