Features and benefits
In the MicroAIR U22, aerosol is generated by pushing liquid medication through fine holes in the
newly developed metal alloy mesh. This is realised by a titanium vibrator, oscillating at high frequency. This unique technology offers the following features and benefits:
True portable, pocket size
The device will fit in any handbag or briefcase. Running up to 4 hours on just two penlite batteries,
your medication is always within reach wherever you go, whatever you do.
Inhalation is possible at various angles
The device enables inhalation at various angles with stable nebulisation. Therefore the device can be
used even while in bed or can be used for a baby/child, laying in the arms of the care-taker.
Soundless operation
The soundless operation of the device enables discrete use.
No loud frightening noises, meaning calm treatment even while using it on a sleeping child.
Simple one-button operation
Wide medication compliance
Low medication waste and residue

Battery life and battery replacement
The unit can operate with alkaline batteries or with nickel-metal-hydride (NiMH) rechargeable batteries. Depending on the capacity and condition of the batteries, the unit can operate upto 8 days on a
set of batteries based on usage of 30 minutes a day.
• When the battery low indicator (orange) flashes, the batteries should
be replaced. Replace both batteries with new ones.

How to select the nebulisation mode
Continuous nebulisation mode
If you push the ON/OFF (O/ I) button and
release within approximately 1 second,
the unit nebulises in continuous mode.
If you push the O/ I button again, the unit stops nebulisation.
The green power indicator lights up during nebulisation.
Manual nebulisation mode
If you hold the ON/OFF (O/ I) button
for approx. 2 seconds or more, the unit nebulises
in the manual nebulisation mode.
The unit only nebulises while you keep on pressing the
O/ I button and stops nebulisation when you remove
your finger from the button.
In this mode, nebulisation may be synchronised with
your Inhalation/exhalation cycle and medication waste is
minimized.
The green power indicator lights up during nebulisation.
How to assemble the unit and fill the medication
7. Install the mask adapter on the main unit
8. Install the mask or mouthpiece on the mask adapter
The device is now ready for use.
Refer to the next section on how to select the nebulisation mode and how to inhale.

How to clean the unit after each inhalation
Note: if the device is not cleaned and disinfected correctly and frequently, micro-organisms may
remain in the unit, causing risk of infection.
The following items should be cleaned after each use:
Medication container, mesh cap, mask adapter, mouthpiece and mask.
1. Remove the mask adapter from the main unit.
2. Remove the medication container from the main unit:
3. Remove the mesh cap from the medication container, discard the medication and open the medication container cap. It is recommended to nebulize clean water to remove medication left in the
mesh holes after discarding the medication.
4. Remove the mesh cover from the mesh cap.
!Caution: Do not touch the mesh.
How to inhale with the OMRON MicroAIR U22
!Caution: Only use type and amount of medications as prescribed
and instructed by your doctor.
1. Slightly tilt the unit as illustrated in the figure.
In this position, the vibrator is immursed in the
medication and nebulisation will start after power on.
After the vibrator has been immursed in the medication,
the unit can be used under any angle.
!Caution: In some positions (e.g. upright), nebulisation may
stop after a short while. In that case, briefly tilt the unit again
in order to re-immerse the vibrator in the medication.
2. Place the mouthpiece in your mouth or place the mask over
mouth and nose.
Always be calm and relaxed when you inhale. Breathe in slowly
and deeply so that the medication can reach deep in to the
bronchial tubes. Hold your breath briefly, then breathe out slowly
while removing the mouthpiece from your mouth. Do not breathe
too quickly. Pause when you feel like having a rest.
You may synchronise the nebulisation with your inhalation/exhalation cycles by using the unit in ‘manual nebulisation mode’. Refer to
page 13.
Note:
If high-viscosity medication is used, nebulisation may be reduced.
If excessive medication collects on the mesh, nebulisation may
stop. In that case, turn off the power and remove the mask adapter.
Absorb the medication by means of a lint-free cloth.
!Caution: Do not poke the mesh with a cotton swap or a pin;
the mesh may be permanently damaged.

How to disinfect the unit each day
Note: if the device is not cleaned and disinfected correctly and as frequently as indicated, microorganisms may remain in the unit, causing risk of infection.
The medication container, mesh cap, mouthpiece, mask and mask adapter should be disinfected
• before using the unit for the first time,
• after the unit has not been used for a long period of time, or
• daily during normal use.
Before disinfection, always first clean the parts as described in the section “How to clean the unit
after each use” on the previous page.
Disinfection of the individual parts can be done, using one of the following methods:
1. Disinfection by boiling.
Note: Main unit, medication container and flexible mask can NOT be boiled. For these parts, use
other methods, as described below.
Mesh-cap, mouthpiece and mask-adapter can be disinfected by boiling in distilled water. After 10
to 30 minutes of boiling, shake off excessive water from the parts and let them air dry on a clean,
lint free (paper) towel.
2. Disinfection by using alcohol.
All parts can be disinfected by using alcohol.
Note: Alcohol is highly flammable; do not use alcohol in close vicinity of open fire; do not smoke.
Soak the parts (NOT the main unit) in 70% ethyl alcohol for approx. 1 minute. Shake off exces
sive alcohol from the parts and let them air dry on a clean, lint free (paper) towel.
Alternatively, disinfect all parts by wiping them off with a lint-free cloth, soaked in alcohol.
3. Disinfection by commercially available disinfectant.
Note: Do NOT soak the main unit in any disinfectant.
Do not use disinfectant containing Sodium (Natrium) Hypochlorite; this may affect the metal parts.
For disinfection of the parts, refer to the instructions as supplied by the manufacturer of the disinfectant. After disinfection, thoroughly rinse the parts with warm tap water. Shake off excessive
water from the parts and let them air dry on a clean, lint free (paper) towel.
How to clean the unit after each inhalation
5. Wash the parts (not the main unit!) in a warm soapy solution.
Rinse the parts in warm tap water to remove the soap residue.
Some types of medications can easily remain on the mesh, therefore pay
close attention during washing.
Do not touch the mesh with a cotton swab, or with a pin.
6. Shake off excessive water from the parts and let them air dry on a
clean, lint free (paper) towel.
7. Clean the main unit and it’s electrodes by wiping it off with a (moistened) gauze.
Use a dry gauze to wipe the main unit dry.
Do not use volatile agents, such as benzene or thinner.
8. Assemble the unit, refer to page 10.
9. Store the unit in a dry, clean place.
