Cleaning The Dust Collector Filter Bags- The Process

  1. First, try to clean up the dust from the outside of the filter bag with your hand or any tool to tap on the bag. Whacking against the wall or other tough surfaces can give you a better clean up too.
  1. You must dispose of the dust layer inside the filter bag using your hands or tools. You have to clean the bag inside out because in this way the bag will lose the caked-on dust that was reducing the suction power of the vacuum.
  1. When you are done cleaning up the inside portion, shake the bag well to remove all the leftover residue dust on the bag.
  1. After that, if you feel the bag needs a bit more clean-up, use a shop vac (like these) or dust vacuum. It will remove all the dogged dust left in the dust collecting bag. Use a vacuum on both sides of the vac to ensure a clean surface of the bag.
All done. There is nothing left you can do to make the filter bag cleaner. Oh no!!!

What About Cleaning The Dust Collector Filter Bag With Water?

If you are wondering why the process didn’t mention cleaning the filter bag in the washing machine, your concern is right. But the thing is, it’s not a proper way to clean your filter bag in the washing machine without getting rid of all the dust and small particles from inside and outside of the filter. Also, it is not recommended to wash in a home-used washing machine unless the machine is industrial standard. For home-use washing machines, there is a chance that the dust will be wriggled into the machine and damage it. Whether you can wash your filter bag or not mostly depends on the manufacturer’s suggestion. Some fabrics are not compatible with dry wash. In that case, you should not put them in the washing machine. Therefore make sure you read the washing guidelines provided by the manufacturer. If you are not satisfied with the clean-up after using a vacuum or shop vac, you can put the filter bag in the washing machine on a gentle cycle. But remember you are not suggested to put it into the washing machine directly.

Things Must Be Remembered

  • Don’t hang the bag under direct sunlight after the wash.
  • Check if the fabric is compatible with a water wash.
  • Use light detergent for washing.
  • The performance of the filter bag may subside due to the wash or clean-up. But that would be worth not spending money on a new one.

Why Should I Clean My Dust Collector Filter Bags?
