Product Overview

Dust from sanding, cutting and grinding concrete, stone, fiberglass and drywall is extremely fine and extremely hazardous. These tiny particles can go straight through typical shop vac filters. Watch the cloud of dust that's coughed out the exhaust port when you turn on a typical shop vac. That does not happen when using a Dustless Wet Dry Vacuum. The optional Micro Pre-filter is NOT just another vacuum bag filter. It captures particles down to 0.5 microns - incredibly close to a HEPA filter that captures particles down to 0.3 microns. That's important because the Micro Pre-filter is an integral part of the patented filter system. It fits inside the main canister and is designed to hold as much as 60 lbs. of dust, dirt and debris. It also retains its strength when wet. The Micro Pre-filter helps keep the primary and secondary filters clean, extending their life. Other vacuum systems lose suction after filling with just a few pounds of dust.

  • Micro pre-filter provides five extra layers of filtration in addition to the two provided by the primary and secondary filters
  • Greatly extends the life of a HEPA filter
  • Captures dust down to an almost HEPA 0.5 micron
  • Retains its strength when wet
  • Peel-and-stick port flap keeps dust from escaping when changing filters
  • Designed to hold as much as 60 lbs. of dust, dirt and debris
  • Large capacity allows for strong airflow with as much as 30 lbs. of dust and debris
  • What's in the bag:2 Wunderbag micro pre-filters
  • Fits all Dustless Technologies 16 Gal. wet/dry vacs

Customer Questions & Answers

Would this fit a 14 gallon Ridgid?

Does anyone know if these fit the 14 gallon Ridgid wet/dry vacs? The Ridgid bags are terrible but say they fit 12-16 gallon units... are these the same (flexible to fit that size)?

Wunderbag Micro Pre-Filter (2-Pack) for Dustless Wet+Dry Standard and HEPA Vacuum is rated 4.8 out of 5 by 25.
Rated 5 out of 5 by from once you try them Once you try using a bag in your shop vac you'll never use it without the bag. It costs a little more to use the bags but keeping the dust contained is what it's all about. The Wunderbag is way better then the regular shop vac bags, much stronger and filters dust a lot better.

Rated 5 out of 5 by from Awesome! These prefilter bags for concrete griding are awesome! The last time I had to grind, I was stoppign to take the cylinder filter out and shake it into a wastbasket every 10 minutes or so (~20 sq. ft.). This time, I ground my whole job (200 sq. ft.) only stopping to check the bag 3x and switch bags once. I'm sure these bags are even better in a Dustless Technologies Vac, but I used my regular 4.5 amp vac and they did awesome. I highly recommend them.

Rated 4 out of 5 by from Great filter bag The bag works as seen on the video. An absolute requirement when using a shop vac during diamond grinding concrete. They kept my vacuums filter clean while grinding 720 square feet of garage floor in preparation to using epoxy. The only down side is as the bag fills keep checking it to adjust the bag in the vacuum or the weight from the cement dust will tear the bag at the location it is attached to the suction location on the vacuum.

Rated 5 out of 5 by from Dustless tech wunderbag These are fantastic. Home Depot missing the boat not handling both vacuum and bags in house. I drywall sand dust free. These bags hold 80 lb of any fine powder. Most drywall installers don't know it exists.

Rated 5 out of 5 by from An excellent product The vacuum itself is excellent, and your price on the pre-filter bags was the best around. One clamp did break off the vacuum, but the system is perfect for our cellar cleaning.

Rated 5 out of 5 by from Awesome dust collection bag I was having serious issues with trying to clean up drywall dust after sanding. Bought this bag and all is well now. Still get great suction out of my shop vac and there is zero dust that seems to make it through the bag. Only thing is I wish I could buy it in the store instead of online only.
