The Atom Sanilizer 303 is a medical nebulizer which has been designed with the highest priority in order to prevent cross infection. This small-quantity nebulization set can completely and effectively nebulize even a small amount of medical fluid. Clean mist is always available from the nebulizer. It has an electrostatic filter which is able to remove over 99% of airborne dust which is as small as 0.1µ in size. The Atom Sanilizer 303 is easy to clean and disinfect as all parts of the air-flow path can be removed easily. The water-level sensor float and drain hose are detachable, making them easy to disinfect and replace. As well as the air-flow path and chamber, all other parts of the device, such as the bottle and the body, can be sterilized with alcohol or sodium hypochlorite.
