This filtration system effectively captures 40% of particles at 1.0 micron and larger, which is 11-times the efficiency of standard pleated filters. This filter also resists moisture found in air conditioning systems, and does not support microbial growth on the pleats.

(We recommend a 1" filter change every month or 12 times per year. For DIRTY environments or most efficient filtration, you may need to change filters more often...do twice-a-month visual checks for the first few months.)
