There are many kinds of portable humidifiers on the market. Basically there are three types: ultrasonic, warm mist and cool mist. The ultrasonic or 'cold spray' humidifier can create an odd problem. In areas with hard water, the hardness minerals (mainly calcium carbonate) are left hanging in the air in the form of a very fine white powder that settles on everything. If the water is hard, it is recommended that distilled water be usedinstead of tap water.
Room humidifiers must be well maintained to prevent health problems.
According to Health Canada, cool-mist humidifiers could pose a health risk if water is left in the tank when not in use. Bacteria can accumulate and multiply in the stagnant water. Persons suffering form asthma, serious allergies and other respiratory problems risk having their condition aggravated.
The residual water should be trown out after each use. The tank has to be cleaned and disinfected regularly to remove any lime and to prevent mould and micro-organisms from forming. Also check and clean the filter often, or replace it if necessary; otherwise, the coating of particles deposited on the
