Customer Reviews:
Met my needs and delivered on time
Collected by Trustpilot.comGreat service, easier and cheaper than the big box stores.
Collected by Trustpilot.comWell, the air-conditioning Contractor said I should use a Merv eight and that was working OK but I was still getting dust so I went to the 11 and I believe the 11 is working very well. I will keep you guys informed.
Collected by Trustpilot.comWith FF I never have to worry about going out and getting filters. They're delivered on schedule
Collected by Trustpilot.comFast service with good quality product.
Collected by Trustpilot.com2 of 12 filters were smashed and had clearly been wet. The remainder was fine.
Collected by Trustpilot.comWork pretty well
Collected by Trustpilot.comDid not reorder anything. I am done
Collected by Trustpilot.comLoved it but it was impossible to fit in my unit. I had to bend it in and the cover was so hard to close. The size was correct but I guess because it was a better filter it was a bit too large.
Collected by Trustpilot.comI change furnace filters (we have two complete HVAC systems) every 90 days. I have no problems relative to furnace filters and the filters are reasonably priced.
Collected by Trustpilot.comQuality is great!
Collected by Trustpilot.comYour filters met my expectations. Very pleased with the filters. Priced right and very easy to order.
Collected by Trustpilot.comGood quality at a fair price.
Collected by Trustpilot.comThey seem to be well made. It's almost time for us to switch out the filters for these and we'll know more later
Collected by Trustpilot.comGood quality filters. Have used them for several years.
Collected by Trustpilot.comWe have been using this product for some time now. Good product and pricing is good also. ALL PERSONAL ARE really good and have good ideas. Thank YOU all. alan trabert, in Va.
Collected by Trustpilot.comFilters work great and really trap the dust and other airborne particles. We live in an area with dust during the spring and summer and we change them out every 3 months.
Collected by Trustpilot.comThese are very good filters. They keep my ductwork spotless!
Collected by Trustpilot.comThe price and quality of this product are good but I had to throw out one of the filters as it arrived dented during transit.
Collected by Trustpilot.comGood basic filters. Cheaper than box store filters. Good service in regular delivery of filter packets, keeps me on schedule to change filters regularly. I have been using Filter Fast filters for about 10 years and will plan to in the future.
