Get premium indoor air safety designed for dental surgeries

Real-time protection for doctors, hygienists, and patients from airborne germs, pathogens, and allergens.

The air in our dental practices

Just as oral hygiene is an important part of our overall health, so too is the quality of the air we breathe. Dental surgeries — particularly those in urban areas — are highly susceptible to poor indoor air quality, while the flow of patients and staff in waiting rooms and surgeries puts practices at high risk for airborne germs and bacteria. Raising the quality of the air in our shared spaces is crucial, especially in sensitive medical environments, and requires more than just a simple air purifier.

Dental Surgeries 1

Dental surgeries need complete indoor air safety.

With patients unmasked, splash and splatter from aerosol-generating procedures, and traces of anaesthetic gases, the indoor air in dental surgeries needs to be treated with the utmost care.


The number of known pathogens1 found in dental plaque, including bacteria from the respiratory tract2, which can be released into the air during aerosol-generating procedures.

1000 ppm

The concentration of nitrous oxide (N2O) in uncontrolled exposures in dental operators. System maintenance, ventilation, and work practices can effectively reduce concentrations to approximately 25 ppm — the recommended limit3.


8 hrs

The amount of exposure to N2O per week4 that can lead to adverse health effects including liver and kidney disease, as well as decreased immune response and generalized neurological disorders.5

Dental Surgeries 2


Dental surgeries are high-risk spaces, where potentially ill patients exhale pathogens that can linger in the air for hours6. VIRUSKILLER™ helps prevent the spread of germs between patients and staff.

We Share Clean Air

Welcome to the family

We’re spending more time inside. But instead of being safe from pollutants, we’re more exposed than ever. Indoor air is on average two to five times more polluted than the air outside8 — yet despite greater awareness of airborne diseases, we continue to share the same contaminated air.

Embrace clean air technology and bring fresh air back inside, and join the community that is committed to turning the tables on poor indoor air.
