If the fines went in the shop vac the filter would plug up right away. Don't put off the purchase because you can make something that works for cheaper. You normally never get around to make anything. Meanwhile you are burning through your filter life and/or going through shop vac bags quickly. How well each system works for coarse, medium, and fine dust as well as with a large vac vs a small vac. I have a dust collector that I hook up to my jointer or planner and that helps a lot.
I had put a new filter in my vacuum and so this was a perfect time for a test. I tested the system with no extra seals but i would recommend putting a thin weather seal around the bottom edge that contacts the bucket. That may improve the performance a little by not allowing air to leak through which pulls dusty air up through the cyclone and into your vac.

Yours looks to have one hose going into one side of the lid and the other in the center of the top? I think most all of them systems would work descent with larger chips but that fine scroll saw dust maybe needs a better system.. I need to check my canister and my vac bag etc..
As you see, the Dustopper reduces flow significantly more than the Dust Deputy. The higher flow rate Ridgid vac drops 45% using the Dustopper and 35% using the Dust Deputy. I was VERY surprised to see how much both cyclones reduced the flow rates of both vacs.

Shop vacs produce enough pressure to implode most 5-gallon buckets. There are a couple ways to prevent this... Using the very fine dust starch, the Dustopper passed 2.5x to 7x more dust than the Dust Deputy. The Dust Deputy was 4x to 10x more efficient across the board.Both cyclones were very efficient at removing coarser dust. Coarse, medium and fine particles which represent the full range of dust produced in most shop. I have removed the DD and yes indeed there is an incredible amount of dust and the larger particle matter is inside the vacuum.
For table saw dust and corn meal the systems seemed to perform equally well with the lower flow rate Vacmaster and the higher flow rate Ridgid vac. The last photo does not show the pink sawdust very well but actually has quite a bit of the dust on the entire filter. I am disappointed on that amount of sawdust.

But no matter what I do there is still going to be sawdust on the floor. So I'll keep doing what I have been doing for years... Sweep it up with a broom and then run the shop-vac over it. This doesn't take very long to do seeing as the shop is so small.
Otherwise, neither cyclone seemed to be sensitive to whether or not the dust bin was empty or near full. ObservationsBoth cyclones performed well with table saw dust and coarse dust . The Dust Deputy passed almost nothing. The Dustopper passed between 0.4% and 1.1%. Not much but still at least 10x more than the Dust Deputy. Owning a Dustopper means rarely having to worry about cleaning the inside of your wet/dry vacuum, or its nasty filter.

I'm not sure how well any of these dust separator things work.. You have to figure that the dust from a scroll saw is very fine dust and not much weight to it.. Easily blown around or sucked up.... Maybe just me but I would think it'd take a decent filter to stop that dust from passing through the hoses and separators.. The problem is that I fill up a 5 gallon bucket of sawdust in 1 day, and then the sawdust goes right into my shop vac, which defeats the purpose of using one of these.
The Dust Deputy passed about 5x more corn starch dust than the Dust Sherriff and the Dustopper passed over 10x more fine dust than the Dust Sheriff. If you collect a lot of fine dust this is significant because the more dust the cyclone separates out the less often you will have to clean your shop vac filter. That means up to 10x longer filter life using the Dust Sheriff. The first one I have hooked up to a craftsman shop vac.
Cyclones use a lot of energy via air friction on the walls as the air spins as well as friction due to the series of direction changes the air encounters along its path. The following chars illustrate how much each vac was affected by connecting each cyclone. The Dustopper passed significantly more coarse dust when it was 3/4 full with the lower flow rate vac.
To replace that specific filter is pricy even when it's on sale. I have used and they work just fine. Don't hook up a dust collector with 500cfm, just use shop vac and it works great.
I put edge of clear tape on fleet farm 5 gallon bucket extra tall and it works fine. You don't need Home Depot Bucket for it to work. If you plan to use a cyclone for sanding or other very fine dust then the Dust Deputy is the clear winner. This chart shows how much of two kinds of dust each system passed using the large shop vac.
As an aside, I use a furnace filter with a 20" fan to trap some of the sawdust from the top of the saw. I am impressed. The filter is pink. We may get paid by brands or deals, including promoted items. It saves your filter, but yeah it depends on your use. If one filter last you many years, it's not worth buying. It's worth buying even at original price.
Not sure if I got a dud but based on my experience I wouldn't take another one of these at any price. All of the cyclones reduced the vac flow rate. With the large shop vac the Dust Sheriff flowed 32% more air than the Dustopper and 28% more air than the Dust Deputy. More airflow means you collect the dust faster so you spend more time on your projects and less time cleaning.
