Independent Lab Test Results

98.6% of airborne virus, gone in 15 minutes.

Third-party labs put PremierOne germicidal UV units to the test — for virus kill and ozone safety. Here’s exactly what they measured.

LMS Technologies · Forced-Air Recirculating Test

98.6% inactivated in 2½ air exchanges.

Model tested
PremierOne MUV7-100DR unit MUV7-100DR

The PremierOne units were installed in a 16×20 air duct. The test room was 4,000 cubic feet, equivalent to approximately a 500 square foot room. Air was circulated through the test room, and within just 2½ air exchanges, 98.6% of the airborne viruses in the room were inactivated in 15 minutes with our MUV7-100DR dual-lamp unit.

Our units purify the air in the ductwork of the forced-air system, not in the living space of a building.

The in-duct MUV7-200QR was evaluated to UL 867 (Electrostatic Air Cleaners, Section 40: Ozone test) and the UL 2998 ozone-emission standard. It tested less than 0.003 PPM in an average 8-hour run time — meaning our germicidal-only units are virtually ozone-free.

Passed CARB 8-hour ozone emissions test

The in-duct MUV7-50DR — a unit with adjustable odor control — was evaluated to CSA C22.2 No. 187:20 (Electrostatic Air Cleaners, Section 7.6). It tested 0.005492 PPM in an average 8-hour run time, with a maximum reading over 8 hours of 0.006020 PPM — far below the maximum allowed of 0.0500 PPM. Our units with adjustable odor control passed the test with ease.
