The present invention is a three stage water-from-air-filter system which can be used in combination with substantially any household vacuum cleaner. The system includes a main cylindrically shaped body and a hollow cylinder within the main body. The main body and cylinder form a ring-shaped chamber. The chamber has a spherical bottom partially filled with water. The hollow cylinder is made of a large pipe and a small pipe. The large pipe has an areohydrodynamic separator. An entrance nozzle may be located on either the main body or on the small pipe. Regardless of where the nozzle is located, polluted air enters the ring-shaped chamber through the nozzle. In the chamber the air mixes with the water. The air and water mixture is centrifugally separated several times through the concentric cylinders within the filter system to ensure a high quality of cleaning.
