Customer Reviews for Dustless Technologies Wunderbag Micro Pre-Filter (2-Pack) for Dustless Wet+Dry Standard and HEPA Vacuum

Dustless changed the bag design from previous generation to this garbage. The yellow seal w/ rubber gasket has detached from 2 different bags now out of the same package set. Each bag was only ~30% full also. Then all the dust material gets sucked into the HEPA Filter Cover which clogs very quickly if your not watching carefully which affects vacuum performance. I have the D1606 so I know I’m using the correct bag as well. Why change what was working before??

As close as you can get to a HEPA without a HEPA keeps the machine clean. It keeps the air clean.

bags work as expected, they contain over 90% of the dust.

Have used these bags for several years. they are great. hold an incredible amount of drywall dust and concrete dust.

I purchase these bags for prote ting my expensive hepa filters. This is a great way to contain drywall dust and make cleanup a snap. I love the fact they put up with any mess, wet or dry. I have sucked up sawdust, drywall dust, and nails along with spilled water and have had no issues with leaking. Great invention. Its also a plus that the inside of your expensive shop vac remains clean.

Fit great work great for sheet Fock dust

Only buy these genuine bags

Work perfectly. Well worth the price.

The Dustless Technologies Wunderbags are quality prefilter bags that do their job without failing. Easy to insert and remove. I’ve had multiple bags weighing more than 40 lbs and the bag has not torn/split.

Drywall work is very very dusty, Dustless Tech is the answer, been using it for years.

Was the best online price for sure. Also beats prices to buy locally

2 out every 5 bags blow apart seams are sown very well.

bag was to large (12-16 gallon) and i needed 8-12 gallon

These bags elevate nearly any vacuum that accepts the size. .Helps preserve the main canister HEPA filter, which can be expensive to replace. Would not run a HEPA vacuum without a containment bag like this. Still see some manufacturers selling HEPA vaccums without making bags available. Total racket, as you can imagine what happens when you try to empty..... Get some..-R

One time use only then it ripped as I was trying to empty it, needed a zipper to make it re-usable, otherwise it is too expensive, great quality though

Essential for the dustless hepa vacuum

Great bags to use in the dustless shop vac

Its works extremley well so much better than the cheap ones
