Performance Series Z-7000 Air Purifier is ideal for large professional spaces such as classrooms, offices, conference rooms and businesses. Use for spaces up to 2,000 square feet. Dual-sided, True HEPA filter (replaceable) helps capture viruses and bacteria, including 99.99 percent of airborne coronavirus found by independent, third-party testing. Activated carbon breaks down volatile organic compounds (VOCs) and odors. 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. Cost-efficient, timesaving UV-C lights are designed to last the entire life of the air purifier. 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.Performance Series Z-7000 Air Purifier is ideal for large professional spaces such as classrooms, offices, conference rooms and businesses.
