We received our filter quickly. The only downside is that It's thinner that the one that is in our furnace now and it's upsetting my husband to no end. I told him the dimensions are right but he is unhappy.

Wish the filter was a tad skinnier. When I slide the filter in, my unit causes the filter to squish and the cardboard on top bends upwards slightly. I can’t just check the filter because the filter tears, I have to remove and replace it
