Maintenance of the humidifier element
The replacement cycle of the humidifier element varies greatly depending on the conditions of use. Refer to the
cycles below as general replacement cycles. (They are not the terms of guarantee.)
• The humidifying performance deteriorates gradually as impurities in tap water are accumulated in the
humidifying element.
• In general, replace the humidifying element when the humidifying performance of the element has deteriorated
by 20 to 40 % compared with that of a new one.
• Estimated operating hours: 10 hours per day X 20 days per month X 5 months per year = 1000 hours per year
• The amount of impurities accumulated in the humidifying element is largely dependent on the water quality
(water hardness, the variety or amount of impurities, the pH of the water, water temperature, etc.) or conditions
of use.
When the water hardness is 25 mg/L Every 5 years
When the water hardness is 50 mg/L Every 3 years
When the water hardness is 100 mg/L Every 2 years
