The DustBlaster Air Cleaning Tool from Carson quickly and effectively removes dust from delicate surfaces--such as those of camera sensors, glass lenses, computers and keyboards--without contact. A safe way to clean fragile items while protecting them against damage, the DustBlaster releases air when squeezed manually. It features a Dust Block tip, which adds an additional valve that prevents dust from being pulled inside the blower. The cleaning tool is made of silicone rubber and includes a clip that attaches to a belt, camera bag strap or backpack for convenience and portability.
