The TruSens Medium Air Purifier features a separate sensor to detect pollutants throughout the room, not just by the purifier. The SensorPod detects common pollutants in the air more accurately to improve coverage of cleaner air. Place the SensorPod away from the air purifier to optimize clean air delivery throughout your space. The purifier automatically adjusts fan speed in response to the SensorPod air quality readings. Improve air quality in your personal space with 360-degree, DuPont HEPA filtration combined with the power of ultraviolet light. The filter helps capture airborne viruses, allergens and certain VOC gases from all directions. The UV-C light kills germs and bacteria trapped in the filter. PureDirect technology uses two airflow streams to distribute air more comfortably. Bi-directional airflow delivers purified air more effectively throughout a room, and in some cases, has proven to be up to 24 percent more efficient than traditional air purifiers with vertical airflow. <p><a id="gfk-spex-minisite" rel="nofollow" href="javascript:void(0)" onclick="javascript:window.open('//content.etilize.com/mini-site/en_us/1067824867.html', '_blank', 'height=800, width=780, resizable=yes, scrollbars=yes, toolbar=no, menubar=no, location=no, directories=no, status=no'), return false, ">More from the Manufacturer</a></p>
