Is It Safe?

Yes. BioShieldUV™ is CE, FCC, and RoHS certified and has been independently tested and verified by the EPA.

BioShieldUV™'s ozone output measures at 0.014 ppm, well below every relevant safety standard.

How UV-C Works

01

Germicidal Protection

UV-C light at 253.7nm irradiates the coil surface 24 hours a day, disrupting microbial DNA and preventing biological growth from establishing.

02

Biofilm Eliminated

Dead biological matter washes away naturally with condensate during normal cooling cycles, restoring airflow and heat transfer progressively.

03

Efficiency Restored

With fouling removed, the coil transfers heat as designed, draws less energy, and maintains consistent airflow without intervention.
