Reduce exposure to airborne viruses in professional large spaces. TruSens Performance Series Z-6000 Air Purifiers are recommended for spaces up to 1,750 sq ft at two air changes per hour (ACH). AHAM-certified smoke Clean Air Delivery Rate (CADR) value of 485 cfm is ideal for large professional spaces such as classrooms, offices, conference rooms, and businesses. AHAM uses 4.84 air changes per hour, so AHAM values are slightly different. The True HEPA filter helps capture viruses and bacteria, including 99.99% of airborne coronavirus. Activated Carbon breaks down volatile organic compounds (VOCs) and odors. (Results from independent third-party testing using aerosolized airborne concentration of human coronavirus 229E over a two-hour period in a sealed chamber. HCoV-229e is a well-established surrogate for SARS-CoV-2.) The TRU-BEAM UV-C system provides exceptional coverage of the True HEPA filter using an engineered array of custom-designed optical reflectors and UV-C lights. The TRU-BEAM UV-C lights are designed to last for the entire life of the product, saving time and money and eliminating the need for replacement. Each air purifier comes with dual-sided filters comprised of a True HEPA filter with highly efficient Activated Carbon honeycomb granules and a durable mesh pre-filter. Filters are specially designed to last at least one year, operating 12 hours per day, under typical operating conditions. No electrical installation or wall mounting required. Simply plug in the TruSens Performance Series Air Purifier, position SensorPod, and it's ready to work. Casters make it easy to move the air purifier from one area to another. Energy efficient and independently certified. The high-performance air purifier is Energy Star rated and independently verified for CADR by Associations of Home Appliance Manufacturers (AHAM) and certified with the California Air Resources Board (CARB). Know your air quality with enhanced SensorPod and the air quality display. SensorPod measures particulate matter (PM1.0, PM2.5, PM10) and volatile organic compounds (VOCs) in the air, communicating real-time readings back to the air purifier. The air quality display on the front of the air purifier reflects the readings from SensorPod with a color-coded ring and air quality number, with details on particulate matter (PM) and VOCs.
