Expected Filter Replacement Cycle / Recommendations / Filter Arrangement

Expected Filter Replacement Cycle

The filter replacement cycle is determined based on usage of 10L per day in a common household, and may be affected by the state of the source water.

Recommendations

Filter Replacement Cycle

Filter replacement cycle refers to a period during which a filter is expected to demonstrate its inherent performance as a result of a thorough review of the filter. This is based on tap water where the inflow water and daily usage amount is about 10L (drinking water for 4 persons) so, if the amount of usage is greater than this, the replacement cycle may become shortened.

Filter Arrangement
