Thanks for all the input so far, I really appreciate it.

I think I may have to change the way I work. I've been using the table saw, bandsaw, planer and sanding in the garage with a dust mask on. I think I need to start using them outside. The table saw is on wheels. The bandsaw is not (it's a bench top model) but it does have a dust collection port that will fit a shop vacuum. The routing, planing and sanding can be done outside with some sort of DC system attached.

Just to clarify: the Wynn filter that goes on the dust collector makes it so I can use the DC inside the shop and no dust will get out, correct? I may go to a work system where I hook the DC up and just use it to collect any dust, even when I'm outside. I thought of using a fan to blow it away, but it often blows back at me or in the garage. I can put the DC I have just outside the garage in the back yard. It will not show from the street so I can store it there since there is no room in the garage. I just need to make sure the hose will reach into the garage. It's on wheels, so I can move it into the garage (provided I move the cars out), hence my question about making sure I can use it with the Wynn filter inside.

I can't have anything that has ports exiting out of the garage walls; the dust will show and the HOA will not approve. I can work with the portable tools outside, though. I think having a DC hooked up will mollify the one neighbor who complains about this sort of thing and be good for me as well.

I use MDF and oak, so I really need some sort of DC system. When I look behind stuff, it's covered with a fine layer of dust. Not good.

Maybe I'll post pictures of my shop so you can all see what I'm dealing with.

I had a thought the HOA would be a problem, especially with an annoying neighbor. I wonder if you can get a metal, or build a wood-framed "Water Heater" cabinet to attach to the back wall, then run a "pipe" back into the garage? You'll need to make sure it has a vent so you don't develop back pressure, but you could line it with sound absorbing material to avoid annoying the neighbor and generating complaints. If you show you mean to make it nice looking and paint it to match the house, you might be able to get it approved. Let them know the alternative is for you to haul all the saws out into the driveway for use, which will be noisier and disturbing to the neighbors. I suspect they will prefer a nice looking, noise canceling enclosure to having your saws out on the driveway.

This is not only a dust collection, but a local politics issue. So if you make it clear, in writing, that you only have a few options to continuing your hobby while being a good neighbor. Most garages have air vents, and you may be able to use part of one to pass the pipe through. I'd be a little less happy about cutting through a wall, but the cabinet will conceal that. Politically I'd present my plan as trying to be nice to the neighbors. I believe most HOAs members know who the annoying people are and will be more likely to approve a small, out of sight solution that reduces the number of noise complaints. Both you and the association know full well that pulling your saws out is guaranteed to set off the easily annoyed. And that you are having either a stock cabinet or a pro carpenter build one, tells them you are doing your best to conform to HOA rules.

You will need to have a sizable air exhaust in that cabinet, and you can buy a cover that holds a large filter, but has vanes that keep rain out. The second filter will completely stop wandering sawdust from triggering a complaint.

One other alternative to consider is to put the filter where it returns the air back into the garage. This will preserve your conditioned air, and also allow you to soundproof the DC cabinet, which may appeal to your HOA. If you can build the cabinet, you can keep the garage door closed when using your noisy tools, and you can soundproof the garage door using heavy, spongy material that, again, won't be visible to neighbors. WIN WIN. If all else fails, you could set up a chamber with non supporting walls INSIDE the garage, which will eat a little space, and still give you the double filtration I spoke of.

I looked at the Wynn filter (https://wynnenv.com/products-page/wo...ilter-pricing/).

1. Should I get the MERV 10 or MERV 15? Is the extra 0.009% worth it/make a difference?
2. Closed top or removable top?

Good idea! All good points. I hesitate to involve the HOA because they might just say no because they really have no idea what this is. However, I might be able to show them pictures/sketches so they can see it will look nice and include your suggestions about the other option being to drag it out in front and make noise, soundproofing, and the other mitigation solutions you mentioned. We are supposed to get approval even for stuff in the backyard, but I don't think anyone does, especially if it doesn't show. I only have one neighbor who is a problem; all the other ones think my hobbies are really cool. In fact, when they hear the saw, they come over and ask, "Watcha buildin'?" The guy down the street has a shop-built cyclone DC system.

I thought I might make an enclosure right outside my garage to store my existing DC in. It would be hidden from the street by a wall. The DC is 58" tall and the wall is 65". I could wheel it out to use it, or even use it in place. Does the type I have (the typical bag type) need a huge exhaust vent? How would I calculate the size needed?

Not sure of the exact size you'll need, but If you used 20x20 filters, the opening should be enough to keep back pressure from building up. In my setup, I have a 20x20 Return Filter Grille, like the one in most houses, to hold a filter for the air returning to the shop. To me, that extra filter can't hurt.

You might be able to get an electrician to hook your DC up to the Electric Dryer outlet that's in most modern houses. Heck, our house was built in 1986 and has one rated at 50 amps. I'm still inclined toward the idea of building an enclosure outside in the back. But you have to live with it, not me.

The more I do, the less I accomplish.

Your table saw is going to be the worst offender. Some are now available with an overarm blade guard/dust collector for that reason. A lot of the sawdust they throw is produced above the table where there is no way for a DC to deal with it without that guard. Plus there is the noise issue.I recall one member several years ago who came looking for sound deadening ideas for them. They are very noisy and the noise is an especially annoying frequency. Using it outside eliminates most of the dust problem for you but that and the noise may be a problem with your neighbors. I suggested erecting a curtain around it at the time which could have a DC drawing air from it to get rid of the residual hazard. A styrofoam box around the saw was also suggested as very low density panels do a great job of deadening sound and the really annoying whine they make is muted significantly.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I got the removable top figuring it would be easier to get really clean if I want to go to the effort. And I have removed it a few times to use the shop vac to clean the insides but it's easy to just blow air from the outside. Even though I don't remove the top often I wanted the option. Also, if you ever wanted to stack two together you'll need the removable top on at least the bottom one.

I don't have a homeowner association, but live in an up-scale neighborhood with doctors, lawyers, etc. so I try hard to be a good neighbor. My saving grace is that I live on the end of a peninsula in a lake, so I try to make my noise on the lake side of my home and shop. The Canadian Geese don't complain, and I wouldn't care if they did, but if the fabric cover comes off my barrel while I'm running my planer outside, the escaping chips sometimes end up in my neighbor's pool, so I then need to work quickly to clean the pool for him.

The exhaust from my central vacuum is piped out through the lake side wall of my shop, up high near the 2nd floor roof, again aimed toward the Geese, who don't complain. It sounds like a small jet plane, so they move to the other side of the lake when it's running. At least they aren't grazing and crapping on my lawn and sidewalks then.

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.

So I'm guessing your not a big fan of Canadian Geese. I hadn't heard a table saw referred to as a Unisaw in years. Had to look that up just in case......

Here's a sketch of what I'm thinking of making. The filter on the side is 20" x 20". The round circle is where the intake hose goes. The door on the narrow side opens for access to the inside of this cabinet. Ill paint it to match the house.
