Airionization. Many air purifiers are equipped
with a special device of air ionization.
Ions are atoms or small groups of atoms
having an electrical charge. They are mainly
generated in nature under the influence
of the ultraviolet radiation. While selecting
a purifier with an ionic filter, it is
to be taken into consideration that some
ionizers emit ozone. Formed by an electric
discharge ozone is a b oxidizing agent,
which may cause serious respiratory ailments
such as bronchitis and asthma.
Productivity. Your choice of the air purifier
should also depend on the volume of the
facility the device will be used in. Household
purification systems are normally designed
for rooms 10-40 m 3 in volume (with ceilings
2.5 m in height). Productivity of an air
purifier is measured in cubic meters per
on hour. Thus in order to calculate it,
the air is to pass through the purifier
at least 3 times per one hour.
Noise level. The factor you should certainly
pay a certain amount of attention to is
the noise level of an air purification
system. This characteristic is not always
indicated in the technical specifications
of a product.. Normally the larger filter
is, the less noise it produces. Most air
purifiers feature several speed modes.
The main mode is usually the low-speed
one, which is the quietest. High-speed
modes are generally used for a short period
of time, i.e. after doing up a room, etc.
