Nanofiber cartridge filters submicron dust at MERV 13

Ultra-Web® nanofiber cartridge filters from Donaldson® Torit® filter submicron dust at MERV 13 efficiency levels.

According to the manufacturer, the filter reduces emissions by 40 percent on 1-micron dust particles and 58 percent on 0.5-micron particles. The filter's nanofiber technology is a cellulose/synthetic composite media with fine fibers that form a weblike net to capture dust on the surface of filter media.

The surface-loading technology promotes self-cleaning in a dust collector and allows dust to be pulsed off during cleaning.
