I ordered 4x20x20 filters from all the big box stores and you were the only one that sent the right size, everyone else the size ran for 4.5 all the way to 5 inches in height.

The filters last a long time and filter the air very well. I've kept one in my central air unit and it had very little debris.

Not 4 inches

Filter fits loosely, not snug like my old filter. I'll still use it them, but won't reorder. Four inch is should be 4 inches, not 3.5.

Not responsive to online inquiries

I have submitted multiple inquiries online to refund/exchnage for correct size and it's been weeks and no response. I will call them, but that's really terrible that they can't respond to a simple request.
