How does the product work?
Ionisation
The ionisation of air can be compared to the feeling one experiences just before
and after a thunderstorm. Immediately preceding a thunderstorm, the air can seem
more difficult to breathe and you might feel tired, this is due to the air being filled with
positively charged ions. After a thunderstorm when lightning has cleared the air, it can
feel easier to breathe again. This is because the air now contains high concentrations
of negatively charged ions. Modern living standards with computers, fluorescent lights
and built-in ventilation systems generate a surplus of positively charged ions.
The air purifier described in this instruction manual draws in air through a 3-stage filter
comprising a pre-filter, a HEPA filter and an active carbon filter. This process cleans
the air of harmful particles such as dust, pollen, irritating odours and exhaust gases.
If the ionisation function is activated, the air will be ionised once it has passed through
the filter. The ionisation process causes the charge in the air to disappear. This causes
any dust particles still in the air to fall to the floor. In order to prevent this dust from
rising up and being sucked into the filter, the floor should be vacuumed about a day
(or as required) after the air purifier has been switched on. Regular vacuuming will also
prolong the life of the filter.
