Bob Adams DC setup is really nice and compact. The 4 inch Super Dust Deputy is a really nice way to separate most of the particles so the filter doesn't get clogged. Minimal floor space and a filter could be attached inside or outside.

The more I do, the less I accomplish.

No link Stick. Here are some other reviews, in the order they came up in a web search:

There are many brands that are better, but they are 2.5 to 3 times the price. If you can afford one with higher CFPM air flow, you might prefer it. However, for a basic DC unit for about $170, I think the HF is a good deal. You can also find informaiton on replacing its impeller with the one made for Jet (about $120), which will dramatically increase flow rates. There are a number of posts on doing this. That is one of Stick's points, that the larger Jet, for example, already has higher CFPM flow, and with a canister filter, does a good job of collection, particularly if you use a chip collector as well.

I have two shop areas, garage and shed, so I needed two units which was doable with the HF on sale with a discount coupon. The Jet or Grizzly was more than I could manage and the HF units work great for me. I have a home shop and do light weight projects. Don't need a pro unit.

The HF unit, with modifications (dust deputy, impeller and filter upgrade) will set you back about 600-650. That’s iff you plan on the upgrades.

By itself, the hf unit is a decent, budget starter machine for one or two tools, but (imho) not for a whole-shop solution.

As long as you enter the fray with an understanding that is realistic, your expectations won’t be unsatisfied...

He already has a DC equivalent to the HF.

I do have a dust collector similar to the Grizzly GZ1028Z2. Sorry, I forgot tot mention that. I took it to work to store it (I don't have any space) and I forgot I had it. It runs on 220, which I don't currently have a plug for, which I could add fairly easily. I suppose I could keep it out of the garage and wheel it in to use.
Yes, add the plug, and wheel it to the machines you'll be using. Get some quick release connectors like the Magports. https://www.routerforums.com/woodsho...thing-new.html

Are you referring to this model? If so then one thing to be aware of is that the cloth filter bags are rated for particle size such a 7.5 micron and so on. The one I got with my Shopsmith came with a standard filter bag which I later changed out for a finer filter bag. "Our standard 12" hood is designed to capture particles as small as 7 microns in size... the 24" model will capture particles as small as 5 microns... and the super 42" model will capture particles down to an amazing 1 micron in size ! The two optional (24" & 42") hoods offer up to four times the surface area of our original equipment hood, and that helps them maintain optimum airflow, even though the internal cake is thickening and the particle size is getting smaller".

And just because you can't see it easily doesn't mean anything other than it's just plain smaller but still not good to breath. I also run a ceiling hung room filtering system with a double filter system and depending on what material I'm working with and the process it's going under (sanding, routing, etc..) I may also be wearing my EZMask or a throwaway rated for extremely small particulates. When you work outside you do have the advantage of the air currents but they may be around you or away from you. Your clothing will likely tell the tale. The DC unit is something you really need to make room for. The one I saw I think you have is on wheels so that should make it far easier than a stationary piped system but you still want to be sure of it's capabilities and that it's doing a good job. I did get the 1 micron bag filter for myself.

If you're using the planer, etc. outside, then the only issue would be what you breathe. A powered dust mask like the Trend Airshield would protect you well. It's not HEPA but filters out enough that your biggest concern would be keeping the filters clean and replacing them in the mask.

If you want to use your machines inside then a roll-around dust HEPA dust collector like Laguna makes (there are others also) could be a good investment. I believe they have a model which is 110V made for connection to one machine at a time. Oneida makes the dust gorilla which is similar. These are pricey. For my money, though, a HEPA filter is best. The lesser filters will get a lot of the dust, but not the finest, which is the dust you really need to keep out of your lungs.

Again, though, if you're just using the machines outside, I'm not sure investment in a dust collector is necessary. Look on other forums, like Sawmill Creek, WoodTalk Online, and the FOG. There are lots of posts about dust collection, but you will get many conflicting responses. I would do some research online, searching for dust collection articles, maybe dust collection and HEPA filters.

Dust collection has a lot of parts, but the most important thing is that you filter out the finest particles possible before they get into your sinuses and lungs.

Using machines outside without a filter or even a DC is not necessarily workable when a homeowner's association is involved.

Regarding the Harbor Freight dust collector, I've had one for a dozen years and it's worked great over that period. As soon as I bought it, I installed a Wynn filter and got rid of the canvas bag. The only issue, if you can call it an issue, is about a month or two ago the on-off switch quit working. Dismantled it, blew out the dust, reassembled it, and now it works again. I don't have dedicated piping. The impeller intake accepts a 5" diameter hose, which I use and then use a reducer at the various tools. It's more efficient that way rather than using 4" hose from the dust collector to the tool. Use one of Harbor Freight's 20 or 25 percent off coupons, and it's an unbeatable deal. If you're worried about longevity, buy an extended warranty.

For peak efficiency with the Wynn filter, use compressed air to blow air through the walls of the filter, thereby knocking off the dust that builds up inside the filter. Make sure the see through plastic bag is attached when using compressed air or else you'll fill the shop with very fine dust and negate all the benefits of the Wynn filter.

Default Festool Dust Deputy Setup for a really small shop

I have a really small shop and do mobile work as well. Since I have a Festool track saw for doing panel work, I decided to add a Dust Deputy Cyclone DIY setup to my existing Midi. The vac is seldom connected to my 12" portable planer runs because the chips are so large there's almost no fine dust. Initially there was no static control, but I got tired of being zapped. The Festool dust port has a metal finger that contacts the anti-static hose connector. Internally a wire connects the clip to the ground terminal. After tapering the PVC pipe to fit the dust port, I added some heavy duty aluminum foil tape for the electrical connection. Problem solved. The cyclone breaks down for easy storage or transport. Below are some pics.

Woodworkers really need a dust collector that catches the finest dust and many dust collectors, especially the bag type collectors, don't catch much of this dust. It goes right through the bag of most bag type dust collectors. The larger saw dust and wood chips make a huge mess if you don't collect them, but it's the micron sized dust that will harm you, and you can't usually see this size dust.

In my small shop I really don't have the space for large ducts and a big dust collector. I do my planing outside the shop and collect the chips in a large barrel. My major saw dust producer in my shop is my Unisaw, and I have to depend on it's base cabinet to collect and hold the saw dust from it until I shovel it out. This is pretty much the same for my band saw. The rest of my tools, sanders, grinders, drill presses, scroll saws, routers, and portable sanders all get connected to my re-purposed central vacuum unit that has a Dust Deputy connected in the line ahead of it. The Dust Deputy collected dust falls into a 20 gallon metal barrel under it. This combination removes 99%+ of all of even the tiniest dust particles from the air stream, but can't handle the large wood chips from planers, etc.. The exhaust from this vacuum is also ported out through my shop wall at the 2nd floor level, so none of even the sub micron dust ever gets fed back into my shop. I also use this system to vacuum my shop floor (after sweeping) and to clean up my tools. I also have an inlet port mounted in the outside wall of my shop next to the passage door so that I can take the 25' hose outside and vacuum my cars and trucks with it.

I now have a 2nd Dust Deputy mounted on a 5 gallon bucket and connected to my shop vac for use whenever I need a more portable vacuum system. I use this system mostly when working away from my shop, like doing home renovation, etc. For this, I have to depend on the shop vac's filter to collect the super fine dust that the Dust Deputy misses, but I only rarely need to use this system.
