The Glasfloss Z-Line 400 HW & HWR
(Honeywell) is
a replacement option for the Honeywell F-100 and FC40R air filters. The ZLine 400
HW & HWR incorporates 100% synthetic fibers that are
thermally-bonded, and manufactured in an engineered gradient structure. The
Z-Line 400 HW & HWR achieves a MERV 8 rating when tested in accordance with the ANSI/ASHRAE
52.2 Test Standard. Pre-applied gaskets on the assembled filters helps prevent
air bypass. Each filter is sealed in plastic to avoid contamination before
use.
