We have been using the Portor Cable vacuums for about 15 years as a drywall company. We started with the previous model 7810. The new 7812 is a vast improvement over the old one, excluding the bags. The old bags you could empty and reuse until they were wore out maybe 5 times. The glue to hold them together held well. The 7812 bags are glued with extremely weak glue. If you're not careful when installing them the flange will separate. The seam on the back of the bag often blows out while vacuuming. Even with extreme care dumping the bags is next to impossible without ruining the bag. I believe the new bags were engineered so you could not reuse them and they succeeded.
There isn't that much exciting stuff to say about vacuum bags, but these are well engineered and even have a nice little flap that seals the hole so dust doesn't escape after you take the bag out of the vacuum. I highly recommend using bags with this vacuum as it allows you to suck up a lot more dust between emptying, and saves wear and tear on the HEPA filter. These seem to last a long time and hold a lot of sawdust or drywall dust.
Price is right and they arrive in time but they seem to be ripping or coming apart at the seam very quickly. Bag will only be 1/4 filled and we have to change it.
Dust has not always been my enemy, but I got tired of it and decided to do something about it. I really dislike sanding dust, especially from dry-wall mud. I tried various shop vacs, wearing them out while wondering if the noise was better than the dust. Porter Cable to the rescue. I bought their first shop vacuum when it came out perhaps 15 years ago. It is still going strong, although I can no longer buy parts (or bags) for it. That old model had a few design faults, as the plastic attachment holders would last for only a day or so, but mine is still running strong, and the filter is still working. However, I needed to get a new model so I could buy bags. The old model works pretty well without bags for wood sanding dust and cleaning the shop, but dry-wall dust needs bags. Porter-Cable 7812 10 Gallon 1-1/2 Horsepower Tool-Start Wet/Dry Vacuum So Amazon to the rescue, as they had a great price on the new models of the Porter Cable vacuums. And now I get to use bags again. I buy them six at a time, and use them for all the dry dust I am picking up, not just dry-wall mud. The nasty stuff is easy to dispose of without making a mess. And I can convert from dry to wet and back to dry quickly when needed. The filter stays clean far longer, and since I am not handling the filter as much, it lasts longer. So get a Porter Cable shop vacuum and buy the bags. The vacuum is quieter than most, there are two sizes, it turns on with your sander, there are great Porter Cable sanders that work with it, the end of the hose can be quickly changed to fit the tool dust port, and the attachment holders now work and don't easily break. Oh, and it does what vacuums should: pick up dust and keep it in the vacuum, not spew it back out into the air. It shows when the bag or container is full. It must be pretty hard to crush the hose, as I have not been able to do it. The Fein vacuums are a little quieter, but there are other trade-offs. It is still a great vacuum company. Here is a link: Fein 9-55-13 Turbo II 9-1/2 Gallon 1-1/3 Horsepower Wet/Dry Vacuum with Auto-Start). I also strongly recommend them.
Bags provide good filtration, but when in use the main seams often open leaving dirt and debris in the vacuum. So far every bag in use has done this. From now on I will reinforce the seam with staples and/or duct tape.
Made of heavy-duty, ultra-strong paper that stands up to wear and tear, these filter bags are compatible with the Porter-Cable 7812 five-gallon wet/dry vacuum. The two-ply design guards against rips, while the 10-gallon size means less bag changes. Another plus is that these bags can be immediately sealed as soon as you remove it from the vacuum, helping to prevent spills or messes, and making clean-up a snap.
