[This review was collected as part of a promotion.] In 17 days my 3yr old Bryant Evo. A/C alerts for filter change, the shortest of any filter I ever used in my air conditioned home of 26yrs. The caked dust/debris is evident as usual but the half life is upsetting. I have CVID causing major immune/allergy sensitivities and really can't afford to pay for 20+ filter replacements yearly from a brand Ive trusted to do as they advertise and last for my money spent. I can only hope the next purchase of filtrete filters will be closer to my brand expectations . Thanks

Maximum Allergen Reduction Filter 1900

[This review was collected as part of a promotion.] The installation instructions state: "Insert the filter...with the arrow on the frame pointing towards the blower motor." However, both the picture and the instruction on the filter show and state that the arrow shows the direction of the air flow through the filter [which is the opposite of facing "towards" the blower motor. Please review the installation instructions for consistency. Thank you.

doesn't fit

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.
No, I would not recommend this to a friend.

Choice of MERV ratings and size

[This review was collected as part of a promotion.] 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.
