NewAire HG2500 Air Hydroxyl Generator
The HG2500 Hydroxyl Generator Air Treatment System is a commercial-grade air purification solution designed to neutralize odors, VOCs, and airborne contaminants using hydroxyl radicals generated through UVC photocatalytic oxidation technology. Unlike ozone shock treatments, hydroxyl systems operate continuously and are suitable for use in occupied spaces when properly installed.
With coverage for spaces up to 2,500 square feet, the HG2500 is ideal for odor remediation, indoor air quality improvement, and surface decontamination in residential, commercial, and industrial environments. Carbon pre- and post-filters help capture particulates and odors, while a built-in timer and continuous operation mode provide flexible deployment options.
This system is commonly used in restoration, property management, hospitality, healthcare, and commercial facilities to reduce persistent odors from smoke, pets, mold, chemicals, and other sources.

Ozone vs. Hydroxyl Generators: What’s the Difference?
Ozone generators and hydroxyl generators are both advanced air treatment technologies used to eliminate odors, bacteria, viruses, and volatile organic compounds (VOCs). While they share similar goals, the way they operate—and when each should be used—differs significantly.
Ozone (O3) is a highly reactive molecule formed by splitting oxygen atoms. Ozone generators intentionally produce elevated ozone levels that aggressively oxidize odor-causing compounds and microorganisms. This makes ozone extremely effective for rapid odor remediation in unoccupied spaces such as smoke-damaged rooms, fire restoration projects, and severe contamination scenarios. However, because ozone can be harmful at high concentrations, treated areas must be vacated during operation.
Hydroxyl radicals (•OH), by contrast, are short-lived, naturally occurring molecules often referred to as the “detergent of the atmosphere.” With an average half-life of less than two seconds, hydroxyl radicals react immediately upon contact with pollutants and then dissipate. In nature, they are formed when UV light interacts with water vapor, continuously cleaning the air we breathe.
Hydroxyl generators replicate this natural process using UV technology to safely produce hydroxyl radicals inside a controlled environment. Because hydroxyls are instantly neutralized during the reaction process, they can be used for continuous air purification in occupied spaces, including hotels, offices, healthcare facilities, schools, and residential environments.
Choosing the Right Technology
The primary difference between ozone and hydroxyl generators is speed versus occupancy safety. Ozone works faster and is ideal for shock treatment in empty spaces, while hydroxyl generators operate more gradually but allow people, pets, and equipment to remain in the area during treatment.
- Ozone Generators: Best for unoccupied spaces, heavy smoke damage, fire restoration, and severe odor removal. Fast and aggressive oxidation.
- Hydroxyl Generators: Ideal for occupied areas requiring ongoing odor control, air purification, and microbial reduction without operational downtime.
In many commercial and restoration environments, both technologies are used together—ozone for initial deep remediation and hydroxyl generators for long-term, safe air treatment—providing a comprehensive approach to odor control and indoor air quality management.
FAQ's
Is the HG2500 safe to run while people are present?
Hydroxyl generators are designed to treat air inside the unit and are positioned as suitable for occupied areas when used according to manufacturer instructions.
Does the HG2500 produce ozone?
The unit uses an ozone-free UVC wavelength (254 nm) and is marketed as a hydroxyl system rather than an ozone shock generator.
What maintenance is required?
Carbon filters and UVC lamps/photocatalytic chambers are consumable components and should be replaced based on runtime hours and environmental conditions.
