The TruSens Small Air Purifier improves 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. Touch-control display is not only easy to use, but it's also easy to keep clean as well.The TruSens Small Air Purifier improves air quality in your personal space with 360-degree, DuPont HEPA filtration combined with the power of ultraviolet light.
