The filters are a littlelsmaller than normal and won't stay in place, therefore all 3 areas are whistling unfortunately :confused:. I really wanted them to work. .

Size matters

While I should have paid more attention to the dimensions, the 1/2" difference in height and width means that the so-called 20x20 flops around in my filter cabinet. Just buy a 3M which will actually fit. The blue filter color is nice.

Poor boxing

While the products seems fine, there is much room for improvement in the boxing of the filters. In truth it makes the company look unprofessional. We received two big "boxes" which were actually to boxes each stacked on each other. Inside the filters (3 per box) were placed diagonally inside rather than fitting along a box edge - basically the filters didn't fit the size of the box. As a result we got two huge boxes for 6 filters. Perhaps by jamming them in diagonally the company saved on cushioning materials but I have never seen this approach before. Again seemed both wasteful and unprofessional. Could be a supply chain issue but the size of the filters seem very standard

I bought these filters in the past and I think they are very well made. I don't know if they compare to the lennox brand but they seam to work just fine
