Z-Line Series Pleated Filters are now upgraded to MERV 10!

Recent changes to the ASHRAE 52.2 Test Standard have resulted in our current MERV 8 pleated filters being upgraded to MERV 10, with no change in pressure drop.  The new MERV 10 upgraded filter models include SB, ZXP, ZL and HV filters as well as 400HW, 400HWR,500/300AB, 700SG and 600GA Air Cleaner replacement filters.
