Without the right upkeep your humidifier will quickly become ineffective, to keep your appliance in great working order and to prevent the device from becoming noisy and expensive to operate it must be cleaned and maintained on a regular basis. However, for many homeowners who have already invested in humidification equipment, maintenance can be a mystery and can cause their newly purchased unit to fall into disrepair.

Whilst the use of a humidifier is well known for its benefits to both health and home, an incorrectly maintained appliance can become a real hazard. Take a look at these top tips from the Air and Water Centre, the UK’s leading specialist in humidification and air quality.


Replace stagnant water

The water in your humidifier must be replaced and the reservoir cleaned once daily to prevent the build-up of bacteria and the growth of mould. Failure to do so can have serious side effects with the inhalation of infected vapour causes an illness often referred to as ‘humidifier fever’. Whilst the effects of the fever carry temporary symptoms it can be particularly unpleasant.

To prevent your humidifier becoming a bacteria breeding ground, empty old water and wipe down the tank with a cloth and mild anti-bacterial cleaner. Add fresh water before humidifying your home once again.

Thoroughly clean

As well as emptying, cleaning and refilling the reservoir once daily, the unit will need to be thoroughly cleansed regularly to prevent pipes and other components becoming clogged and inefficient, especially if you live in a hard water area. How often you have to thoroughly clean your appliance depends on the type of humidifier you have, consult the manufacturer’s instructions for details.  If you have a filtered evaporative humidifier, the filter must be replaced once yearly to prevent dust pollution and mould growth.

Your water choice
