General Information
The PureAir air purification system uses photocatalytic
oxidation (PCO) technology to significantly reduce levels
of airborne volatile organic compounds, cooking odors,
common household odors, airborne dust particles, mold
spores and pollen. The PureAir system is available in
three models: PCO14-23, PCO16-28 and PCO20-28.
Each unit may be connected to either 120VAC or 230VAC
power supply. If 230VAC power supply is used, a 230VAC
power cord must be ordered separately.
Lab tests confirm a 50% reduction in total volatile organic
compounds (TVOC) within the first 24 hours of initial
operation of the PureAir air purification system. It may
take up to 48 hours after initial system start-up to reduce
the airborne chemicals that have built up in a home over a
long period of time.
For peak performance, unit should be installed in homes
with TVOC levels that are less than 1000 micro-gram /
cubic meter. Home source removal and ventilation may be
required to lower TVOCs to this level.
NOTICE
This system is NOT intended to be used for removal
of active mold growth or continuous sources of
high levels of chemicals in the air.
For existing mold growth, the mold must be proper
ly removed PRIOR to installation of the PureAir air
purification system.
