  10.      Poor ventilation causing accumulation of biological contaminations and other air pollutants 


Q: How can we improve the IAQ in our home or office?

A:   To Improve Indoor Air Quality (IAQ) in our home or office :

  1.      Open the windows often to increase ventilation, if air-conditioners are used, maintain good ventilation with sufficient fresh           air supply.

  2.      Clean regularly the ventilation system including air filter and ducting, and maintain the system in good working condition           at all times.

  5.      Dispose of perishable food products properly to avoid generating unpleasant odour.

  6.      Avoid unnecessary partitioning of the premises.

  7.      Select products with no or low volatile organic compounds.

  8.      Move in new furniture only when it has been “aired-out” adequately.

  9.      Provide local exhaust to polluting activities such as heating and cooking, redecoration activities, photocopying, and                   smoking as far as possible.
