    Lots of videos on YouTube and ideas on Pinterest on upgrades to the HF system. Essentially all of them add a pressure drop canister to the incoming air to drop heavy particulate out before it gets to the impeller.

    The angles of incoming air and the cone make a difference of how fine dust it will collect. This system collects talc-fine powder and I used one as a pre-filter for many things from my woodworking tools and sanders, to my old Grizzly dust collector. They just flat out work. They're not exactly cheap, for a 2" inlet and 5-gal bucket size, the $49.95 version would be just fine.

    They even have 5” and 6” system now. That would be awesome for use before the harbor freight collector w a high efficiency bag filter, for those of you who can’t exhaust outside. Would catch a lot before it ever got to the collection bags.

    But of course if you can extract he large particles then exhaust outside? Then it’s a non issue. If you have to exhaust into your shop? I think a dust deputy first, then the harbor freight w the high quality replacement bag would be the way to go.

    Good ones of someone using the 5" in front of their dust collector

    This, in my research, is the best bang for your buck. That is, if you're very serious about dust collection. It is designed by Bill Pentz. I found his site after a bout with Exotic Wood on my lathe. I used African Blackwood, Desert Ironwood, Querbracho, stabilized Exotic Woods and THE worst, Cocobolo as well as some others. I got very sick and researched dust collection and lung damage at Bill Pentz' site. You can Google it. These are professional systems for the smaller shop. I bought their most powerful model. I think initial investment can be lower that $1k. Clear Vue Cylcone Dust Collection is a fantastic company to work with. I haven't got sick since. Well, that and a Trend Airshield Pro (around $300) to protect me as well.
