Humidifying Filter Unit
If water scales are not removed and the unit continues to be operated, reduced humidifying capacity and water
leakage may result.
Attention
Dirt buildup varies by the usage environment of the humidifying filters.
It is recommended that you clean the parts if you notice an odor from the air outlet or a reduction in humidifying capacity (water usage rate).
About every 1 week
Clean by soaking in lukewarm
(about 104ºF (40ºC) or less) or room
temperature water.
About every 1 month or when smell, dirt, or water scales (white and brown) become an issue
Soak in lukewarm (about 104ºF (40ºC) or
less) or room temperature water mixed
with citric acid or lemon juice for about
2 hours. After soaking, rinse with water.
Soak in lukewarm (about 104ºF (40ºC) or less) or room temperature water for an additional 1 hour.
Also, there is a possibility that odor may be coming from the carbon filter, so try following the instructions on
►Page 26

Usage quantities for citric acid:
approx. 20g of citric acid (2 tablespoons) in 3L of water
• Citric acid may be purchased at a pharmacy, drug store or super market.
Usage quantities for lemon juice:
1/4 cup of lemon juice per 3 cups of water
• Bottled 100% lemon juice can be used. Use only 100% lemon juice
with no pulp (strain juice if necessary).
• If you squeeze a lemon, make sure there are no pieces of peel or pips.
• To prevent bad odors and discoloration, be sure to
thoroughly rinse off the parts with clean water.
(Even if discoloration results, it is not a problem for use.)
• The parts can be used even if still wet after cleaning.
• If not to be used for a prolonged period, leave the parts in
a shaded area to dry off thoroughly, then attach.
When dirt inside the unit is an issue
When the water tank is removed, you may find that the
inside of the unit is stained white. These are water scales
caused by dirt in the water which adhered when the water
vaporised, and they are not a problem.
If the stains are an issue, they can be removed.
• Wipe up dirt with a soft damp cloth.
• When dirt buildup is severe, wipe up the dirt with a cloth
which has been moistened with kitchen-use neutral
detergent.
• Do not use a hard brush etc. (Damage may result)
