The PJ-2 Air Circulation Deodorizer by PDM Inc. is an advanced device engineered to instantly purify various unpleasant odors, such as cigarette smoke, feces, urine, and solvent odors, through the powerful deodorizing action of ozone. Its operational process involves air intake, ozone deodorization, ozone concentration monitoring, and the emission of clean air. Key features include a specialized lamp-based system for ozone generation and an integrated ozone concentration monitoring sensor that continuously ensures safe ozone levels. An automatic odor detection sensor intelligently activates the deodorization process upon sensing odors. For enhanced safety, the unit incorporates a secure driving function that automatically deactivates the ozone lamp if concentrations exceed the safety standard of 0.05ppm (compliant with Japan Air Purification Association indoor environmental standards) and reactivates when levels fall below this threshold. The PJ-2 boasts a simple, compact, and maintenance-free design, featuring a durable silver anodized aluminum body that resists deterioration from UV rays. It is energy-efficient, with an estimated electricity cost of approximately 200 yen per month for 8 hours of daily use, and offers flexible installation options, being suitable for walls, ceilings, or tabletops. Technically, the device measures 70 cm x 12 cm x 15 cm and weighs approximately 2.3 kg. It operates on AC100V, consuming 30W of power with an 18W UV ozone lamp. It is recommended for spaces of approximately 6-8 tatami mats, processing about 60 m²/hour of air.
