Product is exactly what I need.Collected by Trustpilot.com
They are very expensive, but they are expensive everywhere. I love the service, quick and efficient, from FiltersFast.Collected by Trustpilot.com
Filters were all under sized by 1/2 inch so the air would just take the low resistance path rendering the filters useless. Called customer service an it was obvious the rep did not care to hear about it. She refund the purchase price and told me to trash them. Such a waste to my time and just more junk for the trash. If you need a furnace filter go with a reputable company not Filtersfast.Collected by Trustpilot.com
