Indoor Air Quality · Hong Kong · Since 1990
Environair (HK) Limited is Hong Kong's authorized distributor of Honeywell air purification products. From system design and supply to installation, rental and maintenance, we return every breath to the clean it should be.
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.



Every breath should be one you can trust.
