Puraclenz Air Purifiers: Certified Zero-Ozone Champions

June 28, 2025

A safer, cleaner way to purify air—without harmful ozone emissions

In today’s world, indoor air quality matters more than ever, but not all air purifiers are created equal. Some technologies generate ozone, a known lung irritant. Puraclenz takes a different approach, offering powerful purification without producing a single trace of ozone, validated by the UL2998 Zero Ozone Emissions Certification.

Reinventing Photocatalytic Oxidation (PCO) for Clean, Safe Air

Many advanced air purifiers use Photocatalytic Oxidation (PCO) to neutralize airborne pathogens. But traditional PCO systems, especially those using unshielded UVC light at 185 nm can inadvertently produce ozone.

Puraclenz reinvented PCO with a patented, ozone-free design. Our technology uses a precisely engineered Photocatalytic Oxidation Cell and a shielded UVC light source operating above 250 nm, far outside the ozone-producing spectrum.

This innovation enables us to deliver the pathogen-neutralizing power of PCO without any ozone byproduct—a breakthrough that sets Puraclenz apart.

Certified Under UL2998: Zero Ozone Emissions

To prove our ozone-free claim, Puraclenz submitted its purifiers for independent third-party testing. Each model passed the stringent requirements of UL 2998, a standard created to validate air cleaners that produce less than 0.005 ppm of ozone—well below federal and state safety limits.

This certificate confirms that Puraclenz products meet the most advanced zero-ozone emission standard available today, making them safe for continuous use around children, pets, and the chemically sensitive.

Why Zero Ozone Matters

Ozone is a harmful pollutant that can cause respiratory irritation, asthma attacks, and long-term lung damage.
While some purifiers quietly produce ozone as a byproduct, Puraclenz eliminates this risk altogether.
UL2998 ensures real-world safety—backed by independent lab testing.

When you choose Puraclenz, you get certified peace of mind.

Additional Safety Credentials

Along with UL 2998 certification, Puraclenz air purifiers are rigorously tested and certified for safety, including:

CARB-certified to meet California’s strict ozone emission standards
UL 507 compliant for UVC containment and electrical safety
ETL-US, FCC, RoHS, and Proposition 65 compliant

In addition, independent lab tests confirm that Puraclenz purifiers create no harmful by-products:

A P3000 unit was tested in a large 30 m³ environmental chamber and shown to produce no harmful VOC by-products or ultrafine particles
The unit also reduced airborne VOCs including formaldehyde, toluene, and D-limonene, validating both its safety and effectiveness in real-world conditions
