Proper Fit
on November 3, 2024
Posted by: Geoffrey J.
I needed filter exactly 21x23. Previously bought from another company filter 21x23 and it was actually 21x231/2 and would not fit. So I bought yours 21x22 and it was actually 201/2x211/2 and too small. So then I bought yours 21x23 and it says on the filter that it is actually 211/2x231/2 and I was upset it wouldn't fit but it truly was 21x23 and perfect fit. Wish I could return smaller ones I don't need (have 3 left)

I needed a filter size

I needed a filter size exactly 21x23. I previously bought another company filter sized 21x23 and it actually was 21x231/2 which didn't fit. So I bought yours 21x22 to besure it fir and it actually was 201/2x211/2 which was too small.So now I bought yours size 21x23 and I was worried because it was labelled actually 211/2x231/2 but it really was 21x23 and fit perfectly. You should correct the labeling. The previous purchase is wasted and wish I couod return them.
