If you're tired of breathing in allergens like dust and pet dander, turn to Aerus for assistance in areas of Montreal and across the province of Quebec. We are based in downtown Montreal (Westmount) and in the West Island (Pierrefonds). Our university-tested air purification systems are designed to inactivate contaminants like mold and viruses. With ActivePure® Technology, you can go beyond traditional air purification systems by eliminating stale odors and reducing dust, and actually eliminating harmful contaminants in the air and on the surfaces of your home. We'll install the systems you need to help you breathe easier.
