Indoor air is often worse than outdoor air

Hong Kong is a world city — but its air pollution index regularly climbs past 100, and the government advises against outdoor activity. The real problem, however, is indoors: studies show indoor pollution can be 2 to 5 times the outdoor level.

We spend over 90% of our time inside. Dust mites, pollen, bacteria, viruses and volatile organic compounds from renovation and furniture accumulate quietly, breath after breath.

Better indoor air starts with three things: control the source, increase ventilation, and specify the right purification equipment.
