Great. Love the way it fits securely into my ACs ceiling return. The filter from a previous manufacturer would fall out before I got the grill up. This one fits snugly making replacement easy. Love it.

I really like the filters. Disappointed when I had to make a return because I have a unique size and there was a charge.

I have not had them in for only a couple of weeks, so really can't review them properly. They are thicker than the cheap ones I bought, so seem good for the price.

Our first order arrived in 2 days. Amazing! The filters are a perfect fit. We had been unable to purchase this size locally except through our Heat & Air contractor. Filterbuy offers the filter at a fraction of the price we were paying. Were very pleased.
