Operating instructions

Before getting started, remove the Clean Air Optima® CA-607W from its box and allow it to become accustomed to the room temperature for at least 30 minutes especially if the machine is cold from the outside air. Place the device on a solid, level and front water insensitive surface, approx. 60 cm from the floor and at least 20 cm from the wall.
The CA-607W is designed to operate at temperatures between 5 -40 ºC and relative humidity of less than 80%.
To get started, grasp the water tank by the handle at the top and lift from the base. Next, flip the tank over and unscrew and remove the water tank lid and filter.

Then place the water tank under the faucet for filling, grasping it from the handle under the water tank. Fill the tank with tap water (or other clean water source with water temperature under 40ºC), re-insert the lid and filter. Flip the water tank once again until it is on the right side up. Ensure that the basin is clean and then carefully place the water tank back on the lower body.

Wait a few seconds until the water tank lid starts to release water into the basin. You will hear a bubbling sound as the air enters the water tank. Plug the power plug into a suitable power outlet, a signal sounds to indicate that your device is in standby mode. If the humidifier is switched on/off, the values for temperature (margin of about 2-5 degrees difference from the room temperature) and humidity will now be displayed.

Power Button:
Press the Power Button to activate the humidifier. The machine is now operating in manual mode. It will release cool mist on a constant basis with the mist intensity level automatically set to medium.

Manual Button:
The Manual Button changes the mist level (low, medium, high). There are 3 levels of mist output available.

Child Lock:
Child lock protects from unwanted use of the device.
The Child Lock is switched on / off by pressing the Manual Button for 3 seconds.
If the child lock is switched on, a red lock icon appears in the display.

Humidity Button:
Pressing the Humidity Button, you can select the desired humidity level by pressing this button repeatedly until the required humidity level is displayed (from 40% to 80% in increments of 5%). Once you select your desired humidity level, simply stop pressing the button and your humidity level will be set.
When the humidity level in the room reaches the set humidity level, the machine will go into automatic sleep state and stop producing mist after 1 minute. When the room’s actual humidity level drops below your set humidity level, then the machine will start producing mist again.

Mode Button:
Pressing the Mode Button once, this will activate the Sleep mode, press 2 times for Auto, press 3 times for Baby, press 4 times for Health. (Sleep-Auto-Baby-Health-Sleep…..).

Sleep Mode:
When the sleep mode is activated, the display will turn off in 10 seconds. Only the sleep mode light is on.

Auto Mode:
Depending on the temperature, the humidifier sets the optimum humidity

Temperature of the air, degrees Celsius Humidity %
19 and lower 65
20-21 60
22-23 55
24-25 50
26-27 45
28-29 40
  • The device determines the temperature in the surrounding of the device (margin of about 2-5 degrees difference from the actual room temperature).
  • The optimal humidity levels with different temperatures are taken from the data base of the device.
  • The device works at maximum power until the optimal humidity is achieved.
  • If the optimal humidity is achieved, then the humidification will stop.
  • The device checks the accordance of the temperature level and the humidity level every 10 minutes.

Baby Mode:
When the Baby Mode is activated, the device turns on the function of warm mist & UV-Light and starts to achieve 55% humidity at maximum power. If the 55% humidity is achieved, then the humidification will stop. The device checks the humidity level every 10 minutes.

Health Mode:
When the Health Mode is activated, the device turns on the function of warm mist & UV-Light, it will calculates the optimal humidity and starts to achieve it at maximum power.
The optimal humidity in Health Mode is calculated as in the Auto Mode, the only difference is that the device add 5% to the result.

Optimal humidity in Auto Mode = 50%, Optimal humidity in Health Mode = 50 + 5 = 55% When the optimal humidity level is achieved, then the humidification will stop.
The device checks the accordance of the temperature level and the humidity level every 15 minutes.

Negative Ion Button:
Pressing the Negative Ion Button will activate the negative ion generator with a total capacity of > 3.000.000 negative ions / cm³ that are spread through out the entire room and thereby neutralize pollutants and smells. Negative ions attach onto dust particles, microorganisms and other unwanted particles in the air and connect them to each other. This way, the particles become heavier than air and fall onto the ground so that you can no longer breathe them in. Negative ions are most found in the forest, mountains and by the sea. Negative ions ensures fresh and healthy air.

Timer Button:
Pressing the Timer Button sets the timer. The timer function determines how many hours the humidifier will operate. You can set the timer simply by pressing it once for each hour that you would like to run the device. The timer can be set from 1 hour to 12 hours. As time passes, the time value decreases until it goes to 00:00 and the device shuts off.

Heating Button:
Pressing the Heating Button activates the warm mist function and is shown on the LED display with three wavy vertical lines. The water is heated in the basin by a PTC heating element and will be heated up by over 65 degrees for killing effective bacteria (Legionella). Heating the water makes the mist output finer for faster and more efficient humidification.

UV-Light Button:
Hold the UV-Light Button for 3 seconds, the device starts the UV Sterilization function, which kills the bacteria in the mist output airflow, bevor the mist enters into the room. The UV-Light icon is shown on the LED display. Press the button again and hold it for 3 seconds to stop the UV-light function.

Automatic shutdown when water tank is empty

Should the water tank be empty, a threefold acoustic signal sounds. The corresponding symbol lights up in the display while the remaining indicators go out. The device will automatically stop humidifying. In this case, turn off the device with the ON / OFF button. Let the device cool down before pouring any more water in the tank.

Caution: The device and the water in the nebulisation chamber (basin) might be very hot.
When lifting the device or removing the water tank right after operation you risk scalding yourself with the hot water!
Ensure that the water tank is always completely refilled.

Preparation Clean Air Optima® Water Filter W-01W

The Water Filter W-01W reduces the limescale in the water and the undesirable emission of limescale particles into the room surroundings. Effective for one to three months, depending on the water hardness. Hard tap water accelerates saturation of the granulate faster so that the Water Filter W-01W must be replaced earlier.

  1. Rinse the Water Filter W-01W for 2 minutes under cold running tap water.
  2. Screw the Water Filter W-01W to the water tank lid.

Determining water hardness:

  1. Dip the enclosed test strip into a glass of cold tap water for 1 second.
  2. Read the water hardness test strip after one minute.
  3. Refer to the table to determine the expected duration of the Water Filter W-01W.

Dispose of the saturated Water Filter W-01W with your regular household waste.
The Water Filter W-01W should not be used longer than specified.

You can order the Essential Oils in our online store at www.cleanairoptima.com


The use of other essential oils not made for this air humidifier or other additives (for example: fragrances and water purification products) can damage the air humidifier and must NOT be used! Never put other pure essential oils or other additives into the water tank resp. the water basin! Even a small quantity can damage the plastic and cause cracks.
The material is not made for the use of additives. One drop is enough to damage the water tank/ water basin and disable the device. Devices that are damaged through additives are excluded from the guarantee.

Cleaning and Maintenance

You can ensure many years of trouble free operation of your Clean Air Optima® CA-607W humidifier by following a few simple maintenance procedures. If your water is hard, containing high concentrations of calcium and other minerals, then over a period of time white dust will start to deposit on the various surfaces in the room. A white, film-like substance will also start to develop in the water basin, on the transducer and on the inner surface of the water tank.
This white film will impede the proper function of the transducer and the operation of the machine.

We recommend the following

  1. If you are using the device on a daily basis, clean the transducer, water tank and basin once a week.
  2. When the water tank needs a refill, empty the remaining water from the tank and fill it with fresh water.
  3. Clean the whole device and make sure to keep all the parts completely dry when the device is not in use.

How to clean the transducer

  1. Place 5-10 drops of vinegar on the surface of the transducer and wait for 2-5 minutes.
  2. Using a small brush, cotton swab or tooth brush, gently clean the mineral film from the surface of the transducer.
  3. Rinse the transducer with clean water.
  4. Never use sharp or solid objects for cleaning the transducer

How to clean the water basin

  1. Clean the water basin with a soft damp cloth. If there is excess film on the surfaces, then soak the cloth with vinegar and repeat the process.
  2. If there is a film in any of the depressions along the basin, drop a bit of vinegar into depression and clean it out with a brush.
  3. Rinse the basin with clean water.


The following is a troubling shooting guide to help you solve any issues that you may have using the Clean Air Optima® Ultrasonic Humidifier CA-607W.

Problem Possible Cause Solution
No mist diffused. Power plug not plugged in.

ON / OFF button not activated. Empty water tank.

Not enough water in tank.

Plug in device.

Press ON / OFF button. Fill tank with water.

Refill tank with water.

The mist has a strange odour. A new device.

It either has dirty water or the water has been stagnant too long.

Remove the water tank, unscrew the lid and let it air out in a cool area for 12 hours.

Clean the water tank and refill with clean water.

The volume of spray mist is too low. Too much mineral scale in the water basin and on the transducer.

Water is too dirty or water was kept too long in the tank.

Clean transducer.

Clean the water tank and refill with clean water.

Device is noisy. Water tank not positioned correctly.

Not enough water in the water tank.

Device is on an unstable surface.

Correctly position water tank on the base.

Refill water in the water tank.

Place device on solid and even ground.

Spray mist is coming out of the area around the mist nozzle. There are gaps between the housing around the nozzle and the top of the water tank. Remove the nozzle from the top of the water tank and clean with a damp cloth. Reattach to the water tank.

If your water is very hard (containing abnormally high levels of minerals) the humidifier may produce white dust. This is not a malfunction. The solution would be to replace the Water Filter W-01W more often or use softer water, like distilled water. Or we can recommend Clean Air Optima Air Washers, more info in our online store www.cleanairoptima.com

If the above recommended solutions do not work, please contact Clean Air Optima technical support at the telephone number for your region. Do not attempt to disassemble, reassemble, or repair the device as this may void the warranty.
