New Ways to Tackle
Old Problems.

Solve your Indoor Air Quality problems efficiently and affordably.

Are Harmful Particles Lurking in
Your Breathing Zone?

Are bad odors threatening your reputation?

Are invisible pollutants compromising your indoor air?

Create Cleaner, Healthier Spaces with GPS Air

 Our NPBI technology reduces even the smallest particles that linger in the air or slip past filters.
Protect Your Air from Small Particulate Matter

Learn how NPBI helps remove small particles that filters leave behind.

Flatten the MERV Curve with NPBI

Understand filter's reduction in efficacy against particles smaller than 1.0 microns.

Learn How Ions Improve IAQ

Keep your indoor air clean with soft ionization through NPBI.

IDF-2™ Ceiling Mounted Ionization Fan

The IDF-2 is a low-profile, quiet operation ceiling tile fan with NPBI™ soft ionization technology removes particles from the air to provide cleaner air where you need it the most.

DM-2® Duct Mounted NPBI® System

Duct mounted soft ionization with auto-cleaning feature to deliver ions where you need them.

CI-2® Easy Fit NPBI® System

Auto-cleaning, no-maintenance, NPBI™ system designed to fit where traditional air ionizers don‘t.

Are Outdoor Pollutants Compromising
Your Indoor Air?

Reduce Even the Smallest Particles and Pollutants in Your Air

When outdoor air jeopardizes your indoor air quality, super charge your filtration with GPS Air OptiLok technology.
Protect Indoor Air Quality from Wildfire Smoke

Improve particle removal, like smoke, so you get the most from your filters.

PF-i™ Filter Enhancement System

This self-cleaning filter enhancement system is built with Opti-Lok™ technology to improve an air filter’s efficiency and ability to capture sub-micron particles. The unit is designed for mounting inside ducts and air handling units upstream of system filtration.


The PF-i can enhance your current filters or be paired with GPS Air Opti-Lok filters to achieve optimal very fine particle* reduction, with the removal performance of our proprietary MERV 11 filter being equivalent to a standard MERV 13 filter.

PF-e™ Filter Enhancement System

This self-cleaning filter enhancement system is built with Opti-Lok™ technology to improve an air filter’s efficiency and ability to capture sub-micron particles. It’s low profile design allows for mounting on typical outdoor air and return ducts.


The PF-e can enhance your current filters or be paired with GPS Air Opti-Lok filters to achieve optimal very fine particle* reduction, with the removal performance of our proprietary MERV 11 filter being equivalent to a standard MERV 13 filter.
