Buying Guide
What space size should guide your choice? For large commercial areas, prioritize higher mg/h output and dual-core designs for sustained performance. For medium spaces, units around 45,000–200,000 mg/h with solid filtration and timer options are often sufficient. Is portability important? Look for lightweight housings, integrated handles, and easy maintenance access. Do you need UV purification? Some models include UV for extra purification; consider safety guidelines and occupancy timing. How important is ease of use? Favor units with clear timers, hold options, and straightforward plate cleaning or replacement. Are these units safe for occupied spaces? All units described are intended for unoccupied-use sessions; follow manufacturer instructions to ensure occupant safety. What maintenance is required? Regularly clean source odors before treatment and ventilate after treatment to revert ozone to oxygen. Always verify local regulatory guidelines for ozone use in commercial settings.
