Newaire HO3-2500 Hydroxyl & Ozone Generator — 2,500 Sq Ft

Newaire HO3-2500 Hydroxyl and Ozone Generator — Dual-Mode Air Treatment for Spaces Up to 2,500 Sq Ft

The HO3-2500 does what neither a pure hydroxyl nor a pure ozone unit can do alone: it gives you both modes in a single machine. Run hydroxyl mode during occupied hours for continuous safe treatment. Switch to ozone mode during unoccupied periods for deep-penetrating shock treatment of severe odors and biological contamination. One unit, two tools, zero compromise.

Restoration contractors rely on this for exactly that reason. Hydroxyl treatment keeps job sites safe while crews work. Then at night — or between occupancy — they dial up ozone mode for the kind of deep-penetrating treatment that breaks down embedded smoke compounds in walls, subfloor, and HVAC systems.

Dual-Mode Technology Explained

In hydroxyl mode, the HO3-2500 operates identically to the HG2500: UVC photocatalysis generates ·OH radicals that safely destroy airborne VOCs, bacteria, and mold spores. Switch to ozone mode and the unit activates a corona discharge ozone generator rated at 2,500 mg/hr — enough to shock-treat a 2,500 sq ft space in a single session. The two systems are physically separate within the unit; switching modes is a single control switch. Ozone mode requires unoccupied space.

Who Needs the HO3-2500

Property restoration professionals who run active job sites during the day and shock-treat overnight. Hotels dealing with persistent smoking-room odors that require periodic deep treatment alongside ongoing maintenance. Veterinary clinics and kennels that need continuous treatment during operating hours plus intensive overnight cycles. The HO3-2500 eliminates the need to own two separate machines and manage two pieces of equipment on every job.

Requires annual ozone generator element replacement (see Generator Replacement Kit for HO3-2500). Carbon filter shared with HG2500. 2-year limited warranty on unit.
