The fi lters are consumable parts. The standard life of the dust fi lter is about 8 years and that of the
deodorizing fi lter is about 10 years. Testing was conducted according to JEM1467 of the Japan Electric
Machine Industry Association. If 5 cigarettes are smoked per day:
[Dust fi lter] Years until the air purifying time is double that of when the fi lter is new
[Deodorizing fi lter] Years until the deodorizing rate is reduced in half when the fi lter is new
The dust fi lter should be replaced early if its color shows the resemblance to the color on the dirtiness
label attached to the purifi er body.

earlier any time the fi lter performance is degraded.
