I keep a box fan with a furnace filter taped over it running constantly. It works great to keep air clean.
Two things a woodworker never has enough of: Clamps and floor space!I've got a hanging Wen box filter with a remote control but so far haven't bother putting it up. As for garage space I was lucky to find a garage 2-car deep and 2 car wide 20' x 40' roughly. Still park 2 cars in the front but use the back half for shop tools. My challenge though is finding floor space or even clear bench space to work on new projects. Add that to a 15 x 20 basement room that has my 25" x 50" CNC and some support tools like benchtop drill press, bench with a router built in, benchtop bandsaw, and small benchtop jointer.
I have a wall mounted roof exhaust fan pulling warm air coming off my wood heater through a pleated filter. The heater, air compressor, and D/C are in a separate room. Filters the air as it heats my shop with recirculating warm air on cold mornings!I keep a box fan with a furnace filter taped over it running constantly. It works great to keep air clean.
You've got a great start. To control the dust you have two choices. First is a self contained filtration unit that is mounted on the ceiling. The second would be a large exhaust fan blowing the dust outdoors. They are rather inexpensive even with filters. I've seen people mount a couple of inexpensive box fans from the hardware store in a widow. You can tape home HVAC filters to them.Today was a great day. I am using a two car garage and splitting as one side containing a workshop and the other side the gym and most often than not the wood dust goes to the gym area. Additionally I was having an extremely hard time finding stuff. So I first built a French cleat wall and got all my tools on the wall. Next I wanted a partition to minimize wood dust going to the gym area. So today I installed a curtain track and two tarps as curtains. Getting the curtain track level over 20 feet required the use of a laser level. Since the depth of the garage is about 20 feet, I got two tarps and attached them together with ball bungees (linked below). It looks great. I am happy to provide additional information if anyone needs it. Also for dust collection I already integrated a cyclone dust collector with my shop vac.
Even with the cyclone it does not collect 100pct of the dust and I see particles floating. Any recommendations? Also any recommendations for a good ventilator I can wear that's not too expensive?

I really like your design for the frame that holds everything, but I took a simpler approach. I drilled a hole in the center of each of the lower corners of the fan, and attached some 1/4x20 eye bolts with washers and nuts. Then I mounted some more eye bolts to the ceiling using plastic drywall anchors, and hung the fans upside down, with a lightweight chain, to give me easy access to the switch, but then later put them on a remote with a timer. I used short pieces of duct tape to attach a MERV 13 filter that is 2 inches thick, to the backside of the fan. Be forewarned, these filters are not inexpensive, ESPECIALLY at big box stores. No filter is going to get everything, but these do a dam good job. Amazon has the best prices I have been able to find. I have 1 of these in my shop in each of the 4 corners, and they keep the dust, mostly under control. I turn them on medium when I'm going to be cutting any lumber, and let them run for an hour on a timer, on high, after I'm finished in the shop. I replace the filters as they fade from white to a dark gray on the intake side of the filter. The nice thing about the shop furniture, jigs, and accessories that we build is that, it doesn't have to look good, but it MUST work good. The key component in your design, and mine, is the filters. The typical household furnace filter will not capture fine dust particles. By the same token, a MERV 13 filter will not work with most in home furnaces, because they restrict A LOT of air flow, and will drastically shorten the life of your furnace, unless the furnace was designed specifically for that filter. If these filters bring my 20 inch box fans to their knees, it's just $20 to get a new one. I'm not sure which filter you used in your solution, you didn't mention any specifics, but I have seen other YouTubers use filters that you could read a book through. Those see through filters are like the stop sign on the corner of my street, it just a suggestion. BTW, I subscribed to your YT channel.This is what i came up with for about 20 bucks.

At least until your neighbor starts complaining about the sawdust.If you re-circulate the air from the box fans (i.e., in a closed space) you need the filters.
But if you put the box fan in a doorway, or window or two (if you have windows in your shop) and the fan is blowing directly outside, you don't even need filters.
If you're not using a MERV 13 (or higher) filter, for the most part, you're just recirculating the dust.I keep a box fan with a furnace filter taped over it running constantly. It works great to keep air clean.
