DustlessTechnologies Wunderbag- Shop Vac Universal High Capacity Pre-Filter bags for Wet Dry Vacuums, 2 Pack (12-18 Gallon). Commercial, Contractor, Professional, Home use. Wet and Dry

Adapt your existing standard shop-vac etc., by modifying the tube that bag slips onto if necessary, and you will never need to clean your pleated filter again (not talking about any 2nd stage HEPA).This bag will filter down to .5 micron so job site dust isn't blown right back out into the air, it's so good that the inside of your tank will be 99% dust free, you will not lose suction picking up an entire mound of drywall dust, like those similar looking paper bags lose suction, meaning the bag will last you a long time inside your 12 to 20 gallon standard vac with excellent suction the whole time.What I'm saying is that these bags are not strictly for the Dustless Tech brand vacs only. I don't own their vac but these bags will make your existing vac perform just like theirs without the HEPA 2nd stage - which is perfect for everything except 'remediation' work.Once you make this change you will never go back. If you're not collecting hazardous material or silica dusts you can actually slit the bag open, empty it into a trash container, and seal it back up with hot glue or use a long pvc pipe clip/clamp and reuse bag without the added weight. They are that good.

these things are great, never used them in the 20 years i have had my shop vac. never even heard of them before but they do a good job, makes it easier to mt the vac

They are not cheep but I love these bags. I recently had to remove some thin set, so I used my angle grinder with a dust extractor to do it. As you might imaging it makes a ton of dust that will quickly clog a traditional shop vac canister filter. So I use these bags in my shop vac with the canister filter and it works great. No only does it keep the suction high it doesn't let any dust pass through them and out the exhaust so the rest of the house isn't covered with dust. If you have a dusty job indoors or outdoors, these are the ticket.

I have been doing brick and mortar demo and using this in my Ridgid shopvac to suck up all the chunks of mortar and brick. It has done an amazing job at that and at gathering the dust from the mortar as I go along. It is very heavy duty and can withstand a lot of weight in the bag. I highly recommend these bags. Only beef is the price...wish they were about half of what I paid.

They work great. In the video they do say something about how much water they can hold. Be aware that if you don't pay attention to that you will most likely have a soupy mess to deal with after. Otherwise, workers as intended. I would reccomend them for messy jobs.

These bags are worth every cent. They will make any wet/dry vac z super hero, your vac will live double its longevity if you use these bags fromthegeh go. Highly recommend.One word on my bill of payment of My and

Hello. So far, this Filter Bag works well and we will buy it again. Thank you.

The bags are on the high side cost wise but they work great. I used mine for several months now during our Reno job. The bags protect my Hepa filter and hold a great deal of drywall dust and saw dust without hampering the filter. I would not use my Hepa vacuum without these bags.
