Exactly what I was looking for. The best quality fabric shop vac bag for my large capacity shop vac. Searched everywhere for a fabric wet/dry bag that keeps dust and everything secured in which tremendously helped with having allergies.Please bring these back! I came to order more and they are no longer available and especially for the larger capacity bags. Please let me know where I can find and order them!

Great filtersMy original brand name filters developed large holes in 5 days these filter much better and have lasted months without breaking down

I used this on a DeWalt 9 gallon stealthsonic to vacuum concrete grinder dust.The connection is sealed well with very little concrete dust escaping to the filter element.

Strong, doesn't get punctured even with nails and wood chips being vacuumed.No dust gets out. The inside of the vacuum is as clean as when I first bought it.

These are good replacement bags for the Turbo ll dust vac. The flippable lid is a nice feature that minimizes the "dust in your face" when disposing.

If you aren't using a bag when using a shop vac... you are doing it wrong. And this is the best bag.I had the dustless vac and loved it. I moved and gave it to my brother in law, now the vacuum is substantially more... substantially..But I had me very spoiled. I could fill my entire vacuum with drywall dust and still have suction a normal shop vac would last a minute before you have to go shake the filter off.I'm going to use these bags In a normal shop vac that has the self clean feature and I should be able to fill the whole shop vac again like I used too, this will protect my "washable" filter that gets super expensive to replace. The bigger the vacuum you have the more economical this becomes. The amount of drywall that one bag can hold without suction loss is as much as the five -six 1/4 full clogged bags you would throw away trying to suck drywall or concrete dust. And obviously you can't put a price on your lungs, wish I was using these when I was younger

I bought these for a basement waterproofing remodel with plenty of mold. Combined with a 5 layer shop vac filter the air coming out of the vac was more fresh than the air in the room. Highly recommend for anyone who cares about doing a cleanup job right.

The HEPA Dustless Technologies Wunderbag is...wonderful!! #D1351.Extremely good with fine dust. 3 bags so far, and each bag I vacuumed about 15 pounds of concrete dust, tile glue, linoleum backing, and inside the shop vac was 99% clean including primary filter. The bag did not tear when lifting it out of the vac, another good sign of quality. The $14/bag might be considered high compared to others, but considering I am not wasting 30-minutes cleaning the vac can or blowing out (or replacing) the primary filter as I did every time I changed the other collection bags, greatly overshadows the cost. After two weeks of trying bags, I am getting 3-4 times the use of each Wunderbag compared to the next best one, and no clean-up time when changing HEPA-Wunderbags just adds to its good design.Note, the key to max use out of the bag is to shake the bag when you feel the suction becoming weak. I turn off the vac, lifted lid, grab top/unfilled parts of bag and lightly shake loose parts of the bag to knock down dust inside, close up vac, turn on, viola, excellent suction again.I bought 12-18 Gallon Dustless Technologies HEPA Wunderbag pre-filter bags (#D1351) in tandem with other bags (paper and fabric). The problem is finding bags that fit the hose nozzle inside my Craftsman 16-Gal 6.5-HP vac (model 113.170660), which is 2-3/4” OD over the retention ribs that secure the bag. The retention ribs create a groove (2-1/2” OD) the elastic seal of the bag seal fits inside; the Wunderbag fits my Craftsman inlet nozzle, a tight fit, but good fit. See photo of half full bags, and the well made seal.HEPA Dustless Wunderbag is quality through and through. The Wunderbag seal is not thin, it is very robust and thick; unlike the others that are very thin and tear when stretching over the nozzle, or did not fit the inlet nozzle (too small in diameter). This seal at the inlet nozzle is the most important part of a collection bag’s performance, if it is a loose fit, dust and debris will escape by the seal as the bag fills and the suction becomes diminished or weak.The Craftsman paper bag is good for debris but not for dust, fine or coarse, it passes through or around the seal and cakes up the primary filter; their seal around the nozzle is adequate at best.I'm working in my basement “cleaning” the concrete floor by removing old linoleum backing, tile glue, some thin set, and paint, and MUST keep the dust down to 'next to nothing'. I’m using the 7” DiamaBrush scraping wheel on my 7" angle grinder with a DiamaBrush shrouded vacuum attachment. The wheel scrapes everything clean and lightly cleans or removes concrete like a regular diamond concrete removal/grinding wheel, and generates just as much dust.The Shop-Vac paper or fabric 9021633, and unknown brand VF2008, did not fit the nozzle inlet of my Craftsman Shop-Vac so I cannot determine how well they filter (or pre-filter). The seals are too small in diameter or the seal tore when trying to fit it over the inlet nozzle.I’ll be using the HEPA Wunderbag soon on the next project, drywall sanding…we’ll see 😊
