Dexwet Pure Air Filters allow the highest airflow stream to pass through a patented staggered rod system. These rods are coated in a non-toxic oil solution to permanently capture airborne particles of all sizes while allowing pure, clean air to flow through, making them ideal for classrooms and any other shared enclosed rooms. Dexwet’s innovative wet filter design is also sustainable, as they are entirely silent, require no energy, and can be washed annually for reuse. dexwetholdings.com.
