Our expert says:
It's likely there are higher levels of industrial air pollutants in your area (relative to urban areas generally, which are all polluted), and sulphur dioxide would be one of these. A variety of pollutants could be contributing to your family's respiratory problems. Keep in mind that indoor air pollution could also be contributing -mould, allergens like animal dander, and tobacco smoke. (Have a look at Health24's 'Healthy Home' section for tips: http://www.health24.com/Healthy_home/546.asp) Usually the recommendation is to promote air flow from outside and through the house; however, if you live where the outdoor air quality is really poor, there is evidence that a well-maintained air-conditioner can help (although air con should be avoided if possible because it contributes to emissions overall). Air purifiers are controversial, and I wouldn't like to recommend a brand without a respiratory expert's endorsement. For example, I would avoid air ionizers and devices that claim to increase ozone levels. I am going to make some enquiries about this, which I will post in due course on the forum. Please also contact me on email firstname.lastname@example.org so that I can follow up on this with you.
