BETTER RESULTS W/ UNIQUE PULSATING FEATURE: Enerzen's O-777 circuit board with 11,000 mg/h adjusts fan speed and ozone output to create a "pulsating" effect. This aids in destroying any lingering "musty" or imbedded odors and results in longer lasting treatments.
DESTROYS ODORS YOU CAN'T REACH: Ozone reacts directly with contaminents in the air, water, fabrics, and walls to destroy instead of mask them. Unlike other types of air purifiers, it does not require air passing through the machine to eliminate odors.
