Honeywell Ultimate Filtration System
FC40R 5" Return Grille Filter by HONEYWELL
(This can ONLY be used if you have a 8" deep return air filter grille and register box.)
(All pricing INCLUDES taxes and UPS Standard Ground shipping.)
(We recommend an FC40R filter change at least twice per year - September and March. For DIRTY environments or most efficient filtration, you may need to change filters more often... do monthly visual checks for the first few months.)
The FC40R delivers up to 98% efficiency on 5 micron and larger particles, effectively reducing dust accumulation on household furniture. The unique face board lowers initial static pressure, which keeps your system's blowers running at peak efficiency.
