Better Air through Science

Solving indoor air challenges – safely and effectively.

We solve indoor air challenges – safely and effectively.

Pro has partnered with Global Plasma Solutions to deliver a patented technology that cleans indoor air without producing ozone or other harmful byproducts. This revolutionary technology fights pathogens and provides safer, cleaner air by reducing airborne particulates, odors and pathogens, as well as saving up to 30% on energy consumption and lowering your carbon footprint. GPS’ patented needlepoint bipolar ionization (NPBI®) products—UL registered and CE compliant—clean the air by introducing ions into the space via the airflow in your ventilation system.

NPBI technology can be found in more than 250,000 installations worldwide. Click the image below to learn more about how we help clean the air in your buildings.
