Dustless HEPA Wunderbag (12-18 Gallon) – Universal Pre-Filter Bags for Wet/Dry Vacuums (2 Pack)

The Dustless HEPA Wunderbag rethinks prem filtration for wet/dry vacuums, delivering enhanced filtration before your main filters. Designed for 12- to 18-gallon vacuums, this two-pack acts as a sturdy first line of defense against dust, hair, and debris.

With five filtration layers, the bag targets particles as small as 0.3 microns at up to 99.97% efficiency. Its design lets it work even when you pull liquids and slurries into the barrel, reducing the frequency of filter replacements and downtime between jobs.
