About Filterbuy 20x25x5 Air Filter (2-Pack, MERV 11), Pleated Replacement HVAC AC Furnace Filters
88% praised for improving indoor air quality, but 12% didn't notice a difference
The filter size is not as per the specifications and it is not fitting properly in the housing.
84% liked its compatibility, but 16% had issues with compatibility
The filter fit perfectly into my standard heater with a 20 x 25 x 5 opening, without any issues.
Sometimes I have to push the filter hard because it doesn't fit perfectly in the slot. The vendor should be careful with the size cuts.
The filter is not compatible with furnace-filters as the door barely closed on the housing.
The first order had wrong sized filters and was longer by about 1/2 inches, so they did not fit.
86% found it easy to install and replace, but 14% had difficulties
I was surprised to find that the filters were too loose to fit properly, causing inconvenience during installation.
90% liked the long-lasting filter, while 10% thought it needed frequent replacements
I am dissatisfied with the filter longevity of this product and would not recommend it to others. It is not worth saving $10 or so over a name brand, quality filter.
92% appreciated its high filtration efficiency, while 8% thought it was mediocre
I love that the filter is Merv 11, which is the standard rating for filter quality. A level 11 MERV filter can remove 60 to 65% of dust particles.
The filter lasts for about a year and then needs to be replaced.
