Beware of "Hydroxyl Generators" That Also Produce Ozone

Not every product marketed as a hydroxyl air purifier uses the same technology.

In today's marketplace, some manufacturers advertise their equipment as hydroxyl generators while their machines also produce measurable amounts of ozone during operation. While ozone is a powerful oxidizing gas, it is fundamentally different from hydroxyl radicals and requires different safety considerations.

If a machine intentionally or unintentionally generates significant ozone, users should understand how that affects where and when the equipment can be operated. California, for example, regulates indoor air cleaners through the California Air Resources Board (CARB), which limits ozone emissions from indoor air cleaning devices and requires qualifying products to meet strict certification standards before they can be marketed as indoor air cleaners in the state.

Titan Hydroxyl Air Purifiers Take a Different Approach

Titan Hydroxyl Air Purifiers are engineered around advanced photocatalytic oxidation (PCO) technology that combines:

• High-output UVA lamps

• A premium titanium dioxide (TiO₂) catalyst

• Ambient humidity (water vapor)

When these three components work together, they generate hydroxyl radicals that help oxidize smoke residues, odor molecules, VOCs, and many airborne contaminants.

Rather than relying on intentionally generated ozone for oxidation, Titan's technology is designed to maximize hydroxyl production through its titanium catalyst and humidity-assisted reaction.

Why This Matters

Many buyers assume all hydroxyl air purifiers operate the same way.

They do not.

Some systems marketed as hydroxyl generators may generate ozone as part of their operating process or as a byproduct of their UV technology. That is why restoration professionals should ask important questions before purchasing equipment:

• Does the unit intentionally generate ozone?

• Has the ozone output been independently tested?

• Is the product certified to applicable indoor air cleaner standards, such as California's CARB requirements if marketed there?

• Does the manufacturer publish ozone emission data?

• Is the oxidation process primarily driven by hydroxyl radicals or ozone?

These questions help buyers compare products based on measurable performance rather than marketing claims.

The Titan Advantage

Titan Hydroxyl Air Purifiers are designed to deliver professional-grade air purification by leveraging the natural chemistry of hydroxyl radicals generated through UVA light, a titanium dioxide catalyst, and humidity. This approach helps reduce odors and airborne contaminants without relying on intentionally generated high concentrations of ozone.

For restoration contractors, remediation companies, property managers, healthcare facilities, and homeowners, choosing equipment built around true hydroxyl technology can provide effective odor control while aligning with applicable safety guidance and regulatory requirements.

When evaluating any air purification system, ask for independent performance data, ozone emission information, and certification documentation. The best air purifier is one that combines proven technology, transparent testing, and reliable performance—not just impressive marketing claims.
