Best Practices for Drywall Dust and Other Fine Dust

The Dustopper will work with drywall dust and other fine dust, but you will more than likely end up with some very fine dust still in your wet/dry vacuum. This is something that all compact cyclonic separators have an issue with. We continue to work on ways to improve efficiency, but here are our recommendations and best practices to ensure your filter stays clean while working with drywall, sawdust and other fine dusts.

Horsepower is very important

More horsepower is better for cyclonic separation, that is why we recommend using a wet/dry vacuum with 5.0 HP or better. You may see some of the finest dust get through, but if everything is running and connecting well, you will see good results.


Use a pre-filter

We encourage this for anyone working with fine dust, including drywall, concrete, etc. Fabric or foam pre-filters help you stop the last bit of dust from entering into your filter and are easy to clean. You can knock it off and keep using it, or you can wash them after use. We highly recommend the FilterPal – CLICK HERE TO LEARN MORE

Use a vacuum bag

If you do not have a pre-filter or do not wish to purchase one, we recommend using high-efficiency dust bags as a substitute. The Dustopper will stop the majority of the dust, so you will rarely have to replace the bags which means even less time and money replacing the filter. You can find them at Home Depot or any other hardware store. Click here to see different sizes. If you are in Canada, click here.

For the Original Orange Dustopper Use Gasket Tape

If you have the Dustopper PRO, skip this step. For the original orange Dustopper only. The less air leaks, the better the separation. When it comes to fines, we highly recommend using Adhesive, Closed Cell 1/16″ Neoprene Foam Tape – 3/8” Width as a gasket on the bottom of the Dustopper. This will create a tighter seal that will help with fine separation. Simply place the tape around the flat bottom part that touches the ring of the bucket. Click here to purchase some tape.

Use a 2.5″ Vacuum Hose

Connect your Dustopper using a 7-foot, 2.5-inch hose. This will help maintain good airflow. Better airflow helps improve separation efficiency. A skinnier hose causes restriction, which impacts fines separation. A longer hose also negatively impacts the airflow, so avoid extra-long hoses.
