People often associate air pollution with the outdoors, perhaps envisioning a sunset turned unearthly colors by smog. But the air inside homes also carries contaminants that trigger allergies and create health issues, but almost never turn the light from table lamps into the same neon colors of a smoggy sunset. The bilingual, extensively trained technicians of Air Fraicheur Plus prevent these issues by suctioning build-up from air ducts with a negative pressure machine, removing contaminants that would otherwise circulate in the home. They suction away bacteria, mildew, and a shocking amount of dust—as much as 40 pounds can collect in ducts over the course of a year. Purer air isn't the only benefit of the company's services: they can also increase the efficiency of furnaces and air-conditioning systems, lowering energy costs.
