Hydroxyl Air Purifier vs Ozone
Hydroxyl Air Purifier vs. Ozone: What's the Difference?
If you're researching professional odor removal equipment, you've probably come across two technologies: hydroxyl air purifiers and ozone generators.
Both are used in professional odor-control and remediation applications, but they work in very different ways.
A hydroxyl air purifier such as the Titan® uses a photocatalytic process involving UVA light, a titanium catalyst and humidity.
An ozone generator intentionally produces ozone (O₃), a powerful oxidizing agent.
Understanding the differences can help you choose the appropriate technology for your application.

What Is a Hydroxyl Air Purifier?
A hydroxyl air purifier is an air-treatment machine that uses a photocatalytic process to generate highly reactive hydroxyl species.
Titan hydroxyl systems use three important components:
UVA Light
UVA light activates the photocatalytic process.
Titanium Catalyst
A titanium-based catalyst participates in the reaction.
Humidity
Water vapor in the air contributes to the hydroxyl-generation process.
The Titan's fan then circulates air through the system and back into the surrounding environment.
What Is an Ozone Generator?
An ozone generator is a device that produces ozone, a molecule made up of three oxygen atoms.
Ozone is a powerful oxidizing agent and has long been used in professional odor-treatment applications.
However, ozone can be harmful to people and animals when concentrations are sufficiently high.
Because of this, ozone treatment requires appropriate safety procedures, including controlling access to the treatment area and following applicable exposure limits and manufacturer instructions.
How Hydroxyl Technology Works
Titan hydroxyl technology is based on photocatalytic chemistry.
The process can be simplified as:
Air → UVA light → titanium catalyst + humidity → hydroxyl generation → treated air
Hydroxyl radicals are highly reactive and can react with certain airborne compounds.
This makes hydroxyl technology useful as part of an overall odor-control strategy.
Titan systems can be incorporated into applications such as:
-
Cannabis odor control
-
Grow room odor control
-
Former grow house remediation
-
Smoke odor remediation
-
Fire restoration
-
Commercial odor control
-
Property remediation
-
Hotel odor control
-
Gym and locker-room odor control
How Ozone Treatment Works
Ozone treatment works differently.
The ozone generator produces O₃, which is released into the treatment environment.
Ozone reacts with susceptible compounds through oxidation.
Because ozone is itself a respiratory irritant and can be harmful at elevated concentrations, professional ozone treatment generally requires the space to be appropriately controlled and unoccupied during treatment.
After treatment, the area must be managed according to the applicable safety requirements before people or animals return.
The Biggest Difference: Occupancy
One of the most important distinctions between hydroxyl and ozone technology is the question of occupancy.
Hydroxyl
Whether people can remain in an area during Titan operation depends on the specific Titan model, operating conditions and manufacturer's instructions.
Never assume that every hydroxyl generator has identical operating requirements.
Ozone
Ozone treatment requires much stri
