The importance of clean air is a matter that has been drawing more attention in the last couple of years with the haze and the increasing number of pollutants in the air. If you’ve never thought about purchasing an air purifier, it’s about time you do! SmartParents spoke with Dr Lim Kai Hung, resident physician at Lifescan Medical Centre, about things to look out for when buying air purifiers:


1. Size and efficacy (which depends on the room/area targeted).
2. Clean air delivery rate.
3. Maintainence should be easy.
4. Noise level.
5. Cost.

For patients with asthma or allergic rhinitis or other chronic conditions, it would be ideal to get an air purifier with a HEPA filter as this ensures dust and pollutants are removed effectively. Keep these tips in mind when picking an air purifier that suits you and your family best.
