Is a porous bag used on a vacuum?

Yes, a porous bag can be used in conjunction with a vacuum, particularly in vacuum cleaners designed for filtering dust and debris. The porous material allows air to pass through while trapping particulates inside the bag. This helps maintain suction power and improves air quality by preventing dust from being released back into the environment. However, the specific design and purpose of the vacuum will determine the type of bag that is most effective.
