Multilayer 3D bag specially designed for the Max Ultimate free-standing aspirator. The filter bag holds dust well. Thanks to the lower edged part and a special notch on the upper part, it takes the form of an aspirator body. The filter bag is reusable. The average life of the housing is 1.5-2 months (with regular care). In order for the vacuum cleaner to work effectively, it is recommended to replace the bag with a clean one at the beginning of the working day. Clean the filter bag with a gentle wash at a water temperature not exceeding 40 degrees. Dry before use.
