Operation Instructions
• Switch off while cleaning the room
After cleaning, it is important to
properly ventilate the room
before using VirusKiller again.
• Switch off while cooking
Oils released while cooking may
reduce the lifespan of the
sterilizing module. After cooking,
the room should be ventilated to
remove oils. VirusKiller can then
be used to remove the remaining smell.
• Ensure airflow is not restricted
Do not position VirusKiller so
that airflow to and from the unit
is restricted by large items
such as furniture, electronic
items or curtains.
• Position at least 3 metres from the bed
To avoid excessive cooling
caused from sleeping in direct
airflow, we recommend
positioning VirusKiller at least 3
metres away from the bed.
• Maintain proper ventilation – 30 minutes per day
VirusKIller is designed to purify
and sterilize your indoor air, and
will do this very effectively if used
correctly. Good indoor air quality
also requires proper ventilation.
We recommend opening
windows or doors, or operating A/C units, for at least
30 minutes a day.
• Maintain regular servicing and maintenance
