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

Continuous nebulisation mode
If you push the ON/OFF ( / I) button and release within
approximately 1 second, the unit nebulises in continuous
mode.
If you push the / I button again, the unit stops
nebulisation.
The green power indicator lights up during nebulisation.
Manual nebulisation mode
If you hold the ON/OFF ( / 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
/ 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 select the nebulisation mode

15
!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 immersed in the
medication and nebulisation will start after power on.
After the vibrator has been immersed 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
14.
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.

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 11.
9. Store the unit in a dry, clean place.
How to clean the unit after each inhalation

18
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 inhalation” 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 excessive
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.

The mesh cap is a consumable part.
Omron recommends to exchange the mesh cap after approximately 1 year.
Remove the mesh cap and install a new one as described on page 11 (section “How to assemble the
unit and fill the medication container”).
Additional instructions for Mesh care
In case the performance of the unit remains reduced even after cleaning and disinfecting, use the
following methods to remove dried medication, lime or saliva which may clog the tiny holes in the mesh
cap.
Leave the mesh cap in a white vinegar solution (1 part vinegar diluted with 3 parts of water) for ½
- 1 hour. In addition, the mesh cap may be kept overnight in a cup of distilled water, in which a tablet
of dental (“false teeth”) cleaner has been added. After cleaning with vinegar or dental cleaner, be sure
to shake off excessive solution, thoroughly but carefully rinse the mesh with distilled water. Shake off
excessive water from the mesh cap and let it air-dry on a clean, lint free (paper) towel.
In case the unit nebulises poorly even after following this procedure, replace the mesh cap.
