Switch off the appliance and 

unplug it from the socket before 

cleaning it. Clean the water tank 

and the base regularly. Use water 

only, no detergents. 

For best results use EZCal custom 

cleaning agent for AIR-O-SWISS 

products to remove deposits from 

the water base regularly. Do NOT 

run the unit when using EZCal. This 

can cause damage to the product 

and voids the warranty. 

EZCal from AIR-O-SWISS is an easy and safe 

cleaning and descaling agent recommended for 

all humidifiers. It cleans mineral build-up in the 

water base.

There is a sample of EZCal included in the packaging of your humidifier!  
Only use 1 packet for 32oz of water. Do not change the ratio. Thoroughly rinse the base with tap water and make 

sure no EZCal residues remain in the base. Instructions for use are on the packet. Please note: EZCal from AIR-O-

SWISS is the only recommended cleaning and descaling solution. Do NOT use any other cleaning solutions since  

it can damage the product. Any use of cleaning solutions apart from EZCal will void the warranty.

AbOUT THE UNIT  

White dust particles are minerals that are broken up in tiny 

pieces by the ultrasonic process. Solve the problem:

•  Soak the demineralization cartridge in a bowl of water for 

a minimum of 24 hours. If the cartridge is soaked in the 

water tank, the water in the tank and the base needs to be 

replaced before using the unit. 

•  Exchange the demineralization cartridge after 1– 2 months 

when you use very hard water, for softer water after 2– 3 

months. No matter how hard your water is, exchange the 

cartridge at the very latest after 6 months.

•  Don’t use water from a pre-installed water softener, or 

sodium instead of calcium will be emitted from the unit. Use 

distilled water instead and remove the demineralization 

cartridge.

•  For very hard water areas use only distilled water and 

remove the demineralization cartridge. 

•  Use reverse-Osmosis water (R-O water) instead of distilled 

water and remove the demineralization cartridge.

•  Switch off the unit and unplug it. Empty the water in the 

base. Rinse the base with hot/clean water. Do not sub-

merge the base! Visually inspect the base for dirt or mineral 

build up. If soft water is used decalcifying the unit every 4 

weeks with EZ Cal is suggested. If hard water is used the 

unit should be decalcified every 2 weeks. Do not forget to 

reset the clean light after resetting the unit.

•  The cleaning light does not automatically reset. Hold down 

the power button (button A in instruction manual) until the 

light stops flashing. The light automatically comes on ap-

prox. after 14 days of plugging in the unit.

•  For best results with your ultrasonic humidifier use distilled 

water and remove the demineralization cartridge.

• Not all hygrometers are calibrated the same, and most are 

off by +/- 5%. Plus the humidity level is not the same in the 

whole room. The air circulation and temperature are diffe-

rent in every corner of the room and may affect the humidity 

level. The unit should not be placed near a heat vent or a 

radiator as the heat will absorb all of the moisture.  

•  If the water tank needs refilling more than once per day, 

the unit is working properly and the climatic condition in the 

room has an influence on the humidity.

Reasons for low humidity level:

•  air circulation is very high (air is fully exchanged several 

times per day – the humidifier needs to starts its work from 

scratch)

•  insulation of home (see air circulation)

•  open space with high ceilings (not only the footage of 

the room counts but also the height) – high-rise buildings 

require more humidification.

•  open windows – works similar to air circulation (if it is very 

cold outside don’t open the window more than 2 times per 

day for 3 minutes)

•  big difference between outside temperature and inside  

temperature – the colder the air the less moisture it is ca-

pable to hold and the more the air is heated up the lower is 

the percentage of relative humidity (= the amount of water 

vapor in the air, compared to the amount the air could hold 

if it was totally saturated)

•  position of the unit – if it is placed close to a door, window 

or air vent. This increases the air circulation.

•  Fill up the water tank. Check if water is flowing through the 

demineralization cartridge (attached to the water tank cap). 

If the water tank is full but there is only little water in the 

base it indicates that the water is now flowing through the 

demineralization cartridge.

•  Wait for 15 minutes to allow the mist to come out of the unit.

•  If the unit is not working and the empty light is not flashing 

you might have set the desired humidity too low and the 

current humidity level in the room is higher. That is why the 

unit switches off automatically.

•  If the empty indicator keeps flashing and the tank is full, the 

water is not flowing through the cartridge. Exchange the 

cartridge or the granules in the cartridge after 2– 3 months, 

in areas with hard water exchange the cartridge after 1– 2 

months. However the demineralization cartridge and or the 

granules must be exchanged at the latest after 6 months or 

the unit does not reach its full performance anymore.

•  If the granules are new, see the following instructions: 

Make sure the cartridge and/or granules were soaked 

for 24 hours, dry granules take even longer for water to 

filter through the cartridge and into the base. Next, please 

remove a tablespoon of granules from the cartridge, and 

throw them away. When there are too many granules in the 

cartridge it does not allow water to flow from the tank to the 

base.

•  How long has it been since the contents of the cartridge 

were replaced? If 2-3 months have passed, it is time to 

replace the contents of the cartridge. However the demine-

ralization cartridge and or the granules must be exchanged 

at the latest after 6 months or the unit does not reach its full 

performance anymore.

•  If the contents of the cartridge were just replaced there are 

probably too many granules in the cartridge. Remove a 

tablespoon of granules from the cartridge.

ACCESSORIES

•  Yes, always keep the water tank cap (this is the piece that 

attaches the demineralization cartridge to the water tank).

•  The ISS is effective in preventing the growth of bacteria and 

molds in standing water. It needs to be replaced once a 

year. The ISS can be used in all AIR-O-SWISS products plus 

in all other humidifier brands.

•  The ISS is effective in preventing microbial growth in stan-

ding water. Please see the quick set up guide for more 

instructions.

•  In each ISS box and on all the new products there is an 

ISS lifecycle indicator. Check the box of the month when 

starting to use the ISS and write the year on the line in- 

dicated. Exchange it after 12 months.

Do not submerge base in water! The 

cleaning indicator still appears on 

the display after cleaning. To reset 

hold down the ON/OFF button 

until the clean light stops flashing. 

Thoroughly rinse the base with tap 

water and make sure no EZCal 

residues remain in the base!
