Guidelines for replacement
● Replace the cartridge in the following situations even when the cartridge life indicator has
not reached the "End (Replace)" position.
When either of the following events has occurred:
● When the volume of purified water has decreased
● When the odor of the water cannot be eliminated
When 1 year has passed since the cartridge started to be used
Cartridge performance
Filter (cartridge) replacement (change) timing
In approx. 1 year if the product has been used to make 10 liters of
purified water a day
● How long the filter is good for (usage period) differs significantly depending
on the content of the organic substances contained in the water and the
extent to which the water is cloudy.
● The usage period may be shorter if well water is used.
● When the product is used to supply fresh water, water for tea, coffee and other
drinks, water for cooking rice and so on for a family of 3 or 4, approximately 10
liters is normally used a day.
● When purified water is also used in washing rice, vegetables or dishes and in other
kitchen jobs, the volume used will increase so the usage period will decrease.
Notes
● The volume of purified water may be less in the following cases:
– When the water temperature is low (because it is then harder for the water to pass
through the cartridge)
– When the product is used in an area where the water pressure is low (under 70 kPa)
– The pressure of city water constantly changes depending on how much water is being
used in the area so the volume of purified water may decrease at certain times of the
day.
– After a suspension of the water supply, for example, immediately after water service
work has been done, the volume of purified water may decrease.
● The cartridge is made of plastic.
Dispose of a used cartridge in accordance with the applicable local laws and
regulations.
