Shop Vac Water Filter
While this is not a new idea, many of you may have never seen anything like this. Thoughs of you who have or have seen the Rainbow vacuum knows that it uses water as the filter. While building our house and tired of cleaning/buying filters for my shop vac, I decided that I would figure out a way to make a water filter for it. My set-up uses the smaller shop vac and hose, a 5 gal bucket with a lid (the lid I use has a rubber seal in it), and some assorted pieces of shop vac hoses accessories. Drill 2 holes in the top of the lid just big enough for the hose connector to pop in. Then you will need to connect a long tube that will extend down into the bucket (about 2” from the bottom).The other tube will only extend down a few inches. Hook one hose to the shop vac and then to the SHORT tube. Hook up your other hose to the LONG tube…this will be the end you use.Now put enough water in the bucket to cover the end of the long tube by a few inches. The vac will pull a suction through the water, and all of the dust and dirt will be trapped in the water. I don’t have a whole shop vacuum system, and I hate paying $12 dollars for the pleated filters..This system works awesome. You will hear lots of bubbling and gurgling while it is running, and there will be some water carry over into the shop vac (so only use the foam sleeve). If you use this for Sheetrock dust cleanup (this is the best damn thing in the world for this BTW) you will need to clean the water out fairly frequently. For sawdust removal every few days (depending on how much you use it). Mine is not fancy or pretty, but it works fantastic. One of these days I will make a better one, fixing the water carry over issue, and I’ll put it on some sort of dolly so it can roll with the Vac. Check out the pictures. I hope this helps some one.
Oh, BTW, about 6 months after I made this thing, I saw something similar in the Sheetrock section at HD. It was only there for a short time, and I don’t think they sell it anymore, so much for me making any money off this idea.
