Aerosol therapy is also characterised by the braking down of water particles up to an extremely reduced diameter including less than three micron.

Aerosol therapy is similar to regular inhalation treatments and differs above all for the fact that the inhalation process takes place at the same temperature as that of the spring water. Regardless of the methods used to break down the water particles, thermal water is used in the same chemical conditions found at the springs.

There are also particular forms of aerosol therapy which have been developed in relation to the problems they aim to treat. Thermal aerosols with a low level of break down of water particles (which must not measure less than 12 microns in diameter) which are brought to a temperature of approximately 36 degrees centigrade are available for the treatment of rhinitis and sinusitis and bronchial asthma.

An ultrasound aerosol has been developed in order to ensure a high level of homogeneity of particles and is a much more advanced instrument compared to the equipment used normally. The method allows for optimal absorption of the water by the membranes and can be used in order to introduce the water into the eardrum cavity.

The sonic (or ‘vibrated’) aerosol is characterised by the fact that the vaporised material is vibrated using ultrasounds and then administered to the patient subsequent to acceleration using compressors.
