THE LEGENDARY SENTINEL PURIFIER

UNDERSTANDING NPBI TECHNOLOGY

Needlepoint bipolar ionization works to safely clean indoor air and hard surfaces, leveraging an electronic charge to create a high concentration of positive and negative ions. These ions travel through the air continuously seeking out and attaching to particles. This sets in motion a continuous pattern of particle combination. As these particles become larger, they are eliminated from the air more rapidly.

 

What exactly does that mean? 

 

As the positive and negative ions are released by The Sentinel Unit, they attach to particles, pathogens and gas molecules. The ions help to agglomerate fine submicron particles, making them filterable. The ions neutralize pathogens by robbing them of life-sustaining hydrogen. The positive and negative ions are proven to reduce VOCs including BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes). The ions produced travel within the air stream into the occupied spaces, cleaning the air everywhere the ions travel, even in spaces unseen.

Positive and Negative Ions delivered by Needlepoint Bipolar Ionization

What is an ion? 

 

An ion is a molecule or atom that is positively or negatively charged, meaning that it has electrons to give or needs electrons to become uncharged, thus becoming stable.

NPBI TECHNOLOGY IN FIRE APPARATUS AND VEHICLES

Once installed in a vehicle, The Sentinel delivers the NPBI-generated ions that circulate, actively seeking out contaminants and pathogens – neutralizing, deactivating and reducing them in the breathing space.

  • Neutralizes VOCs, viruses, bacteria, and mold in the air

  • Hard surface sanitizer

  • Only attacks single-cell organisms, safe for humans and pets

  • Easy installation – simply mount with supplied brackets, hard wire or plug in with supplied cigarette plug adapter

  • Allows responder vehicles to remain in-service longer 

  • Unlike air filtration systems, NPBI activity works on all size particulates, even smaller than .3 microns

  • UL 2998 Certified for No Ozone Production. Link Here: UL 2998
