I have two DC units. One is a Delta with the Wynn, the other is a HF with the Donaldson filter. The HF unit is hooked to my jointer & planer only. The Delta is hooked to my fine dust producers (saws, sander, router). Both filters work very well as intended. Both units have the same Thein design separator connected to them. Neither unit allow dust to into the collector bags provided the dust bin is not over filled. I have installed little windows into the side of the garbage cans to watch the levels. My shop is in the basement so effective dust collection is not only critical, its very visible! There is a physical size difference between the two filters but I believe they have the same merv rating. I have not tried swapping the two filters around but the smaller Donaldson filter tends to retain more particulates within it than the Wynn does. I have had the the Wynn setup for over 3 years now and am very pleased. I probably do more work than the average hobbyist, but less than a full time pro. I added the HF unit about a year ago but the Donaldson was just added about a month ago. The other difference between the dc units is that the HF unit has a larger collection bin as it collects mostly large sized particles. I have not noticed any differences in the amount of dust that escapes either of the filters. Which is what is critical. But I do have to do a bit of a filter cleaning with each bin full of dust I collect especially on the Donaldson. My suspicion is that the smaller filter is the reason. But at 1/4 the cost of a Wynn filter shipped, I’m more than willing to do it! It was the cost differential that had me get the Donaldson filter over another Wynn. Cost is why I have two used DC units vs. one bigger unit and why I didnt use super dust deputy cyclone units vs. my Thein separators. Both units with all modifications included cost me less than $500 total.

P.S. I used to double filter bag my HD unit which worked fairly well initially, but found out later on that once the second bag got saturated with fines, it would then send them into the air. That is the main reason why I added the Donaldson cartridge filter. The cartridge filters have better Merv rating to them and do not spew visible fines accordingly.
