According to the *EPA (2021), indoor air averages about 5 times more pollutants than outdoor air. What are the solutions to creating a healthier environments? Learn how to:

1. Eliminate unwanted air-borne particles.
2. Reduce allergens, odors, and smoke.
3. Kill viruses, bacteria, and mold.

Breath Cleaner, Fresher Air

NeedlePoint Bi-Polar Ionization (NPBI) creates both positive and negative ions that release into the air. When added to the air, they break down passing pollutants and gasses into harmless compounds such as oxygen, carbon dioxide, nitrogen, and water vapor.

When the ions come in contact wit viruses, bacteria, or mold, they remove the hydrogen molecules leaving the pathogens with no source of energy, ultimately killing them. NPBI takes care of these issues creating a healthier environment without producing any harmful byproducts.

Surface and Air Decontamination

Installing UV Lights provide additional health safety through air supply decontamination for building occupants.

When passing through UV light, pathogens are effectively killed by the ultraviolet light. The UV light reacts with titanium dioxide infused into carbon, which degrades the captured contaminants, leaving only harmless water vapors and carbon dioxide is released back into the air.
