How Does It Work?

Units with ActivePure Technology pull free oxygen and water molecules in the air through ActivePure's patented honeycomb matrix. The technology creates powerful oxidizers, known as ActivePure Molecules, that are then released back into the room, where they seek and destroy DNA and RNA viruses including SARS-CoV-2 (novel coronavirus), Swine Flu (H1N1), Avian Bird Flu (H5N8), Hepatitis A (HAV) and MS2 bacteriophage, regardless of their size, on surfaces and in the air.

Safe, Proven, Effective, Certified.

PuriFi Responsive Air and Surface Purification System

How Does It Work?

The PuriFi PM Sensor provides real-time feedback of particulate levels to the PuriFi Smart Hub, signaling the patented PuriFi Generator, installed in your HVAC system, to respond to air quality changes. This in-room Sensor works by pulling in air at a constant rate, drawing airborne particles through the laser particle counter, and reporting results every 90 seconds.

When the Sensor detects that particle levels are too high, based on user-determined thresholds, the Generator is notified, and the system operates until the Sensor verifies that your air is purified and again within your target air quality levels.

Cleaner Air Within Your Business

Commercial Indoor Air Quality Americans spend up to 90% of their time indoors and many spend most of their working hours in an office environment. Studies conducted by the U.S. Environmental Protection Agency (EPA) and others show that indoor environments sometimes can have levels of pollutants that are actually higher than levels found outside.

Pollutants in our indoor environment can increase the risk of illness. Several studies by EPA, states, and independent scientific panels have consistently ranked indoor air pollution as an important environmental health problem. While most buildings do not have severe indoor air quality problems, even well-run buildings can sometimes experience episodes of poor indoor air quality.

Benefits of adding an air purification system to your office or retail space

  • Help protect the health of yourself, your employees and your customers
  • Help reduce sick time from illness
  • Reduce germs and viruses from the air and surfaces
  • Reduce employee stress and increase production
  • Reduce odors
  • Reduce pollen, smoke and vehicle exhaust that may come in from the outside
  • Reduce mold and mildew spores
  • Reduce VOC's from office equipment, office furniture and building materials (flooring adhesives)
