Portable Air Purification Technology

The technology in Field Controls' air treatment products are backed by science. The CDC, WHO, and ASHRAE all recommend UVC and HEPA filtration to improve indoor air quality and reduce airborne disease transmission. Independent lab testing confirmed TRIO Plus unit reduces virus1, bacteria2, and fungi3 due to the H13 HEPA filtration, capturing >99.97% of 0.3-micron particles, two powerful UVC lamps, and photocatalytic oxidation (PCO) technology, reducing Volatile Organic Compounds (VOCs). These harmful chemicals are converted to odorless, harmless water vapor and Carbon Dioxide. VOCs are released by common products like:

  • Paint
  • Pesticides
  • Solvents
  • And other chemicals

All of Field Controls Portable Air Purifiers do not generate harmful ozone and pass the strict California Air Resource Board (CARB) ozone requirements. Field Controls’ lamps convert ozone back into safe, healthy oxygen. Ozone is a toxic gas which can damage the lungs when inhaled. Even low amounts can cause chest pain, coughing, shortness of breath, and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.

WARNING: This product can expose you to chemicals including Mercury, which are known to the State of California to cause birth defects or other reproductive harm. For more information go to
