Nominal size of HVAC filters is a problem for some users. The problem is made worse by the lack of standardization in return air grille sizes. For example, filter manufacturers print 18"X18" on a filter, but the nominal size can make it impossible to use them in a return air grille, if the builder bought cheap odd-size grilles. For the past two decades, I have had no problem with the Filtrete size in my house. Not true for other filters I tried. I have a large return air grille that I have to tape two 18X18 together to use. 18X36 is not a common size to find and I do not think Filtrete makes this size (with 18X24 the largest I could find). Once I bought another big-name brand. After taping the two together, the length of the filter was too short. [This review was collected as part of a promotion.]
I have no idea what to do with this BETTER AND HIGHER END filter... this is the first time a 16 x 20 x 1 inch filter purchased at the local hardware store DOESN'T FIT. I have an AC unit with a more precise slot in which to insert the filter. No matter how I try, it just won't slide down the frame as required. I can't return the unit for a lower grade filter because I didn't save the receipt.
I have used nothing but Filtrete Allergen Filters for the past 15 years. I trust them to keep us healthy and allergy free in the home. My wife has asthma so its imperative we have the best air filter we can get. That is why I buy Filtrete. [This review was collected as part of a promotion.]
