Great product and my mother needs clean air as she has some surgery that need clean air flow in this house as to not get Bacteria floating in the air..
We shopped for filters and these were one of the best prices we found for MERV 11 filters. My allergies feel much better after a week of running new filters. We ordered a case of them and are very happy. Thank you very much.
The purchasing progress was easy as expected, but I ran into some serious walling when I asked about returning the wrong sized filters. I expected a return tag or something but was told that returns are on my own.not to happy about it.
