Customer Reviews:
These are the best AC filters. My AC man highly recommend them .
Collected by Trustpilot.comWell manufactured product.
Collected by Trustpilot.comAlthough the purchased size was identical to other brands (20 x 20 x 4), the actual size of the filter was about a 1/4 to 1/2 inch smaller in all directions. It seems misleading to round up the size in the advertising. There is a gap around the filter that will allow a small bit of unfiltered air to pass through to the HVAC and reduce the effectiveness of the filter. I will use these up, but will not be buying them again. It's too bad because the filter itself and construction seem decent, but the skimped size makes it not worthwhile or effective.
Collected by Trustpilot.comIt arrived on time and in good condition and fit our furnace.
Collected by Trustpilot.comTried to save some money by buying the generic “Filters Fast” brand 20”x25”x4” filter to replace my Honeywell filter, also 20” x 25” x 4”, and it’s the wrong size! Don’t market it as a replacement product if it’s not equivalent!!! How was I supposed to know the actual dimensions were different than the size advertised? The actual size is not listed when you're viewing the product. Very disappointed.
Collected by Trustpilot.comThese are exactly the same filters that the local HVAC company sells for 2x-3x the price. Also less expensive than the local HVAC supply company.
