operation. They are designed to prevent injuries or damage to this device.
Safety Precautions
The inner ultrasonic transducer is highly sensitive. Do not touch it with bare fingers or
scrape it with metal tools, or it will reduce mist output. When cleaning this area please use
a small cleaning brush, cotton swab or tooth brush. Do not use hot water as it may damage
the misting parts.
Use proper voltage - AC 110~120V 60Hz in Canada/USA; AC 220~240V 50Hz in Europe.
Use of improper voltage may cause fire hazard or electric shock.
To prevent electric shock, do not dismantle, repair or modify this product. Maintenance and
cleaning should be followed exactly as instructed in this manual. In the event of a
malfunction, please contact an authorized Clean Air Optima maintenance center.

Do not place this device in direct sunlight or near objects that generate high temperature
heat. The heat may cause deformation or warping of the outer casing.
Do not use the humidifier in a room that already has humidity levels above 50% relative
humidity. Excessive humidity in the room gives rise to condensation on cold surfaces such
as walls or windows.
Do not operate the unit without water in the basin.
Do not insert foreign objects into the device. Do not touch the transducer or the lower
water basin when the unit is operating. Do not scratch the transducer. Do not touch the
mist output when producing warm mist.

Diagram humidifier CA-601
The Clean Air Optima CA-601 is equipped with a Permanent Reusable White Dust & AntiMicrobial Filter. It consists of an inner cylinder, an outer cover and a number of small plastic and
ceramic balls. The plastic balls are embedded with nano-silver, an anti-microbial agent designed to
purify the water and destroy microbes such as bacteria and mould. The ceramic balls function to
soften the water by adhering to minerals that cause white dust. They also serve to remove any
unpleasant odour from the water. The filter requires cleaning about once a month or 1,000 hours of
use. See the Maintenance section of more information.
Operating Instructions
Before getting started, please remove the Clean Air Optima CA-601 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. The CA-601 is designed to operate at temperatures between 5 -40 ºC
and relative humidity of less than 80%.
To get started, first remove the nozzele than flip the tank over and unscrew and remove the water
tank lid and filter.
Then place the water tank under the faucet for filling. 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 cord into the electrical outlet
Turn the ,,Mist adjustment Knob" to the right to turn the humidifier on. The water will be turned
into micro-fine steam trough high frequency vibration, which will be dispensed into the indoor air
and directly evaporates. Make sure that the steam does not face electrical sockets, walls or other
Push the ,,ION/Light” button to turn the Ionizer and Led light on.
The air will be enriched with additional negative ions. The integrated ionizer cleans and refreshes
the air with additional negative oxygen ions. The effect is completely natural: After a summer
thunderstorm the air is filled with negative ions and especially fresh.
Amount of ions per cubic centimetre air:
In high altitude: 8000 ions /ccm
At sea level: 4000 ions / ccm
Countryside: 1200 ions / ccm
In the city: 2000 ions / ccm
In the office: Only 20 ions / ccm
In case there is no or too little water in the tank you will hear a signal.
The percentage of water steam in a room and the temperature are the relative air humidity. The air
contains more or less air humidity. The ration of water steam to the air varies with the different
temperature. The higher the temperature in the room, the less water steam will be in the air. In
winter the cold air from outside enters the room, the relative air humidity decreases. The air
humidity can be increased with the Clean Air Optima air humidifiers.
The relative air humidity should be:
Bed and living room: 45 -60 %
Examination room: 40 – 50 %
Library: 40 – 50 %
The following is a troubling shooting guide to help you solve any issues that you may have with the
operation of the Clean Air Optima CA-601.

Too much mineral scale in the water
Clean transducer.
Water is too dirty or water was kept too
long in the tank.
Clean the water tank and refill
with clean water.
Vibration in the water tank because
the water level is too low.
Fill the water tank.
Machine is on an unstable surface.
Move the unit to a stable flat
There are gaps between the housing
around jet nozzle and the top of the
water tank.
Remove the jet nozzle from the
top of the water tank and clean
with a damp cloth. Reattach to
the water tank.
Abnormal noise
Spray mist is coming out of the
area around the jet.
The following is not considered faulty operation:
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 clean the
filter more often or use softer water.
If you stand very close to the humidifier, you will hear the gurgling sound of water. This
is normal.
The machine operates very quietly but it is not completely silent. Noise levels less than
25 db is considered normal.
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, repair
and reassemble the machine as it may void the warranty.
Cleaning and Maintenance
You can ensure many years of trouble free operation of your Clean Air Optima CA-601 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 your water is very hard, we recommend that you boil it first, allow it to cool completely
before use in the humidifier. The boiling will reduce the mineral concentration in the water.
The other option is to use distilled water if your mineral level is still too high.
2. If you are using the machine on a daily basis, clean the transducer, water tank and basin
once a week.
3. When the water tank needs a refill, empty the remaining water from the tank and fill it with
fresh water.
4. Clean the whole machine and make sure to keep all the parts completely dry when the
machine 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 transduce
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.
How to clean the White Dust & Anti-Microbial Filter
Remove the filter from the water tank.
Put some white vinegar into a glass. Soak the filter in the vinegar for about 10 minutes.
Remove the filter from the glass and shake it several times.
Clean and rinse the filter once again with fresh water.
If you don’t plan to use the humidifier for a long time, remove the filter from the water tank and let
it dry thoroughly. Then wrap it in protective packaging and keep it next to the humidifier in a cool,
dry and dark storage space.
Why humidify the Air?
When the air is dry, especially in the winter months, it can become unpleasant and even unhealthy,
leading to increased levels of static electricity, dry skin, cracked lips and even noise bleeds.
Optimal humidity is between 45 to 55% relative humidity. During the winter months though,
relative humidity in the average home can drop to below 20%. Low humidity can lead to a variety
of conditions that cause ill health. Dust particles, bacteria, viruses, dust mite feces that are
normally trapped by the moist nasal membrane lining in the nose can more easily get into the
lungs when the air is dryer and thus reduce the body’s natural defence mechanism. These invaders
overload the immune system and irritate the mucous membranes resulting in more coughing and
susceptibility to disease. The Clean Air Optima CA-601 is an ideal ultrasonic humidifier for
homes, apartments, offices and anywhere where is low humidity. Ultrasonic water vapour is highly
beneficial to individuals. Their biggest advantage is high performance combined with low energy
Do not use additives
Water additives (e.g. essential oils, fragrances, water conditioners etc.) must NOT be used! Even a small
amount can cause damage to the tank material. The material is not suitable for the use of such
additives. One drop is enough to damage the tank and render the appliance unusable. Appliances that
are damaged by such additives will not be covered by the manufacturer’s warranty.
