UVC AIR PURIFIERS OF THE STERIWHITE
AIR Q-SERIES DISINFECT THE AIR QUIETLY,
RELIABLY AND WITH HIGH EFFECTIVENESS
The Corona pandemic has brought the transmission of
infection by aerosols and thus the importance of disinfected
indoor air for preventing infection to the attention
of society for the first time. With more than 30 years of
experience in the field of UVC disinfection, Dr. Hönle AG
has developed the SteriWhite Air Q series of mobile air
purifiers, which are a fast, safe, and effective solution
for indoor air disinfection.
SteriWhite Air Q units are available in four versions,
which differ in air flow rate per hour (115 – 900 m³/h)
and thus in size. All models reliably inactivate viruses,
bacteria and other germs in the air and reduce the
germ load of indoor air sustainably and inconspicuously.
Because with a sound pressure level of only 35 to 39
db(A), they are demonstrably below the concentration
threshold.
The SteriWhite Air Q is available as a stand-alone unit
or for wall or ceiling mounting. It meets the highest
photobiological safety standards and produces neither
ozone nor other harmful substances. Lamp replacement
is simple and is only required after 16,000 hours of
operation. No other maintenance is needed.
Based on “COVID 19 Aerosol Transmission Risk Calculator“ of the Max-Planck-Institute for Chemistry:

Assumptions: Room height= 2.5 m; persons performing sedentary work; persons not wearing face masks; percentage of time
talking 20 %; example calculation office for 4 persons: Risk of at least one further person being infected if one person present is
highly infectious; without air cleaner 50 %, with Q600 air cleaner 6.6 %, which means a reduction in the risk of infection of >80 %
