"One of the big advantages of the Dustless HEPA Wet/Dry Vacuum is the optional Micro Pre-filter that greatly extends the life of the HEPA filter. The Micro Pre-filter is an inexpensive disposable filter that captures the vast majority of the dirt and dust before it reaches the more expensive HEPA filter."

Near HEPA Filtration

Have a vacuum that spews dust out the exhaust? Turn it into a dustless vacuum with this bag.

Our micro pre-filter bags captures 99.97% of particles at 0.5 microns. That is 0.00005 centimeters across, much smaller than most dust particles. Although this bag is not HEPA rated, it can make any vacuum have superior filtration.

Use Wet and Dry

This bag can be used with wet applications, including water and slurry. The user can go between wet and dry materials and the bag will not lose its filtration nor its strength.

Filtered water will slowly leech from the bag while all of the contaminants remain inside the bag. This allows you to throw out the bag and dump out or reuse the filtered water for quick and easy cleanup.


1. Place the bag evenly in the vacuum

2. Pull the cardboard opening tight around the port

3. The quick installation is complete
