HOW SHARP AIR PURIFIER WORKS

An air purifier draws in room air from its air intake, lets the air pass through an Active Carbon Filter (Deodorizing
Filter) and a HEPA Filter (dust collection filter) inside of the unit, then discharges the air from its air outlet.
The air purifier unit repeats this process by moving its internal fan.
As air passes through, the HEPA Filter can remove dust particles. The Active Carbon Filter gradually absorbs odour
elements as they repeatedly pass through the filter.
(Odour elements are absorbed by HEPA Filter as well.)
Some odour ingredients absorbed by the filters may become separated and may be discharged through the air outlet
and result in additional odour.
Depending on the usage environment, this odour may become strong in a shorter period than expected.
In this case, purchase the optional replacement filter kit FZ-28SEF.
NOTE
The air purifier is designed to remove air-suspended dust and odour, but not harmful gases (for example, carbon
monoxide contained in cigarette smoke). Neither can it completely remove odours that are always present (for
example, odours from construction materials and pet odours).
