It all started with the Standard Air Purifiers and accessories. Our focus was to create an air purifier that is beautifully designed, simple to use, and beneficial to your living space. So that’s what we did. We combined exceptional functionality with a sleek, contemporary design. TruSens Standard Air Purifiers feature PureDirect bi-directional airflow and a control panel to set preferences, like fan speed. The Medium Z-2000 and Large Z-3000 Standard Air Purifiers also feature an LED display to alert you of changes in your air quality, and a remote SensorPod air quality monitor to sense air pollutants and communicate across the room to the air purifier.
