The hygienic humidification mechanism and Aera Sense Technology makes the Philips AC3821 Air Purifier what it is. For starters, we have a suggestion- You must be using a steam-console when you catch cough and cold right? Try once to use it for a different purpose. Use it in a closed room and keep it running and spewing steam for 1 hour. You’ll feel a marked decrease in pollution levels and haziness in the room. A humidifier is a much more intelligent version of the steam console. It helps maintain the optimum humidity levels as it senses it and alters its evaporation rate accordingly.
The ideal relative humidity level is between 50-70%. Anything more or less than this range is problematic. Greater humidity may result in growth of fungi or molds and foul damp smells. Unusually dry air may cause irritation in the respiratory tract or other skin related issues.
