Safer Indoor Spaces
Begins With Clean Air.

ActivePure® Technology is an active air purifier technology that puts back into the air the same therapeutic molecules that make our outdoor air pure – molecules that actively neutralize pathogens and volatile organic compounds (VOCs) as they enter the space. ActivePure® provides a layer of protection that reduces airborne and surface pathogens quickly and effectively. ActivePure® has been extensively tested for both its safety and efficacy against airborne and surface contaminants in occupied spaces.
