Obviously generic filters...nothing on the packaging to guarantee MERV 8 status, air 'passability', necessary flammability status, durability (appear more flimsy than Flanders), etc. I checked off Flanders filters and was referred to these...I would hope they are of the same quality. How do I know?
Your service was excellent and the filter fits as we needed, I'm glad you had the measurements we needed as we did not find any in local stores. You have our future business. Thank you.
