The MERV 10 media replacement performs equal to or better than original equipment performance. It delivers up to 98% efficiency on 5 micron and larger particles, effectively reducing dust accumulation on household furniture. The unique face board design lowers initial static pressure, which keeps your system's blowers running at peak efficiency.
(This can ONLY be used if you have a Media Air Cleaner of some type, i.e. Honeywell Models F100/F150/F25)
(We recommend a 5" filter change at least twice per year - September & 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.)
