New Filters for New A/C System
on June 24, 2025
Posted by: Anonymous
Put in an order for new filters for a new A/C system we just had installed. Different size and MERV than I have been ordering the past 10 years and was amazed that the new filters came in the next day! Great service and great product.

The correct size was 18x18x1 at 11 MERV. They seem to be doing well. Thank you for this unusual size.

Frame is a 1/4 off

Frame is a 1/4 off in length. I return them back. They sent 6 more, still short and the actual measurements are off in length. I like your filter but I need 29 and 3/4. Not 29 and 1/2.

Better than the supply house

Even in a crunch they deliver on time, the variety of choices is much better than any supply house. I use them in my home and for my AC business.

I ordered the same size
on June 16, 2025

I ordered the same size I always order and the filters did not fit. Way too big. The size I needed was wrote on the side of the filters as usual. Im not sure if they got mislabeled somehow or what. Very disappointed at a waste of money.
