Check the listing for details. SheMax filter for dust collector PRO and V PRO. Condition: New with box. Listed at 29.99 USD. It is highly recommended to change the filter every 2 months if you have a full time clientele. SheMax came up with a technology that allows you not to accumulate dust on the walls of the motor, harming it, but to instantly absorb all the dust into the compartments without residue. It's all about the filter, which is installed directly above the dust collector motor, so it "catches" it before the "entrance". The compressed dust loses its “mobility” property and is easily disposed of without residues. That is why SheMax began to use closed compartments instead of the traditional dust bag.
