The only thing I can think of is would like to see a MERV 10. .
I cannot use anything higher because my Trane unit tries to suck it up into the upper works.

Having a six month supply of the correct size and high quality filter keeps us on schedule to regularly service the unit.

Great service. My unit requires an odd-size filter and the only stores in this area don’t carry that size. It is so convenient to be able to receive the filters on a scheduled basis without even having to think about it.
