I searched high and low including local hvac companies for an affordable merv 11 filter in an unusual size, and filter buy was by far the best option. Thank you!
The pleated portion of the filter is not glued or attached to the frame (card board)very well making it very easy for the induced air to bypass the filter. Size is smaller than the filter I am currently using. Again air can bypass the filter. I am not happy with the quality of the filter not the way it fits into my duct work housing.
I bought this filter to replace my Honeywell 16x20x4 filter. I did get the 16x20x5 filter as it has the same measurements as the Honeywell 16x20x4 filter. This filter fits perfectly. The quality of the filter is excellent as it is very firm and sturdy.
