During winter the dry heated air in homes and offices can irritate the nose and the throat. This irritation is reduced by use of humidifiers. However, humidifiers, if not used properly, can create perfect conditions for mould and bacterial growth. Use of humidifiers in confined areas with the doors and windows closed could result in condensation and mould growth on the walls. Mould is a recognized health hazard. Humidifier water can also support bacterial growth.

What to do:

1. Monitor the humidity level to ensure it is between 30 and 50%
2. If you must use a humidifier, buy the kind that uses steam or boiled water
3. Regularly clean the humidifier as per the manufacturer’s instructions to prevent microbial growth in the water.
