Even my HVAC contractor suggested disposable filters & the quality of the Accumulair Diamond Merv 13 filters is excellent!

Excellent selection of products and customer service

Been using for years and always get the best service.

Filters fit perfectly where the old EAC system was. Packaging was good, and the size was easy to find.

Happy I can still get these filters. Not ready to give this machine out.
