HG-1500 Hydroxyl Generator – Odor & Air Treatment for Occupied Spaces
The HG-1500 Hydroxyl Generator uses advanced photocatalytic hydroxyl technology to eliminate odors and treat airborne pollutants inside its reaction chamber. Compact, lightweight and ozone-free, it’s safe for continuous use in occupied areas such as offices, schools, hospitality spaces and maintenance rooms.
How the Technology Works
The HG-1500 creates hydroxyl radicals—highly reactive molecules that naturally occur outdoors when sunlight reacts with moisture in the air. Indoors, the HG-1500 replicates this process using UVC 254 nm light and a catalyst, generating hydroxyls that react with smoke, odor molecules and airborne contaminants as air passes through the unit.
Hydroxyls are extremely short-lived (less than 2 seconds) and break down pollutants on contact. They remain inside the treatment chamber, making the process safe for occupied environments.

Photocatalytic Hydroxyl Generation
-
Hydroxyl radicals (*OH) are known as the “detergent of the atmosphere” for their ability to break down pollutants.
-
They are formed when UVC light energizes water vapor, creating reactive ions that neutralize contaminants.
-
The HG-1500 uses UVC at 254 nm, which does not create ozone.
-
A catalyst surface is required for true hydroxyl production—this is what differentiates hydroxyl generators from ozone generators.
UV-C Spectrum Clarification
-
UVA (315–400 nm): Black-light range, no ozone.
-
UVB (280–315 nm): Tanning lamps.
-
UVC (100–280 nm): Germicidal range.
-
254 nm: Germicidal, ozone-free (used in HG-1500).
-
185 nm: Produces ozone (not used in HG-1500).
-
Why the Catalyst Matters
-
Units using UVC without a catalyst = UV ozone generators (not hydroxyl generators).
-
Units using UVC 185–254 nm + catalyst = produce hydroxyls but also ozone; for unoccupied use only.
-
HG-1500 uses UVC at 254 nm and a catalyst to produce hydroxyls inside the chamber, without ozone.
