The filter I removed fit snugly. One bought from you is much slimmer though the dimensions printed on it are the same. I submitted a review before. No reply when I asked if this narrow filter will allow too much unfiltered air pass through.
A 4 inch filter means more filter material and less drag on my A/C motor. it works as I hoped it would. Ill be using the 4 inch filters in the future for sure.
