Setup, Compatibility & Care
To install, align the filter cartridge with the intake port on the BB3000 mask and rotate until you feel the locking mechanism engage. Always perform a negative pressure seal check by covering the filter intakes with your palms and inhaling slightly; the mask should collapse against your face if a proper seal is achieved. Regarding care, store unused filters in a clean, dry, and cool environment away from chemical vapors or excessive humidity. Do not attempt to clean or wash these filters; if they become damaged, damp, or difficult to breathe through, they must be discarded and replaced immediately.
