I’m planning to buy the HF DC as soon as I get the money together and it goes on sale again so I’m researching canister filters to replace the bag. I have been all over the internet and it’s driving me crazy. I want something that will fit this DC and give me a minimum of 99.9% but I don’t want to pay $100. Someone suggested truck air filters but not only are they just as expensive, I have read that they don’t hold up for as long as the woodworking specific ones. What do you guys suggest? Should I just cough up the money for a $100 filter?

The HF DC is on sale now for $209 and the 20% coupon makes it $167. I think you’re going to have to just suck it up on the cartridge filter and pay the $$$ if you want one.

That would be my suggestion…suck it up and cough up the money.

If it works for you, you can just exhaust outside and skip the filter altogether.

Get over all the high priced options. I have that collector, and use the felted bags from Highland Woodworking. I use ‘em top and bottom, shake ‘em out twice a year, DONE.
I don’t have an industrial set up. Home shop, but they work for me with the table saw, surface planer, bandsaw.
They are felted. Don’t wash. Empty and shake. No disposable bags which are WAY too expensive.
I’ve had this set up for almost 7 years, and would buy it again.
As you well know, you can go nutso tryin’ to get the optimum results, spend a fortune, and still wonder if you’ve gotten the “best”.
Just my way.

That could totally work for me. Any tips?

Maybe put a thein separator before exhausting outside.

About truck filters,I don’t know where you are looking but the ones I use are about 1/2 the price of the Wynn ones, rated merv 15 @99.9% (same as the DC filters), and so far are lasting better than the Wynn that I have in my Az shop. I think most of what you have “heard” about truck filters is from those who haven’t tried them.
Be aware that the price of truck filters seems to vary more with sales volume of the particular filter than quality.
You may have to shop a bit but it is worth it.

My setup is shown in this blog.

I plan to but probably can’t right away. I can vent out the back of my shop right onto the compost pile

The drawback to outside venting comes in the winter if you are heating the shop. If that’s not a problem, go for it.

I can isolate the dc to a closet and then vent to outside. That might just work

That doesn’t matter, you’re still pulling warm shop air through the DC and venting it outside.

You can’t easily buy the truck filters on the internet. I got mine on eBay, but it was a one-off purchase from a seller who was selling a few random truck parts. You have to find a local semi repair shop and buy one off them. That way you save on shipping. Shipwright got his from a local shop for about what I paid.

A few notes about venting outside from my experience:
1) I built a Thien separator. I couldn’t vent out all the dust straight outside. I’d have a mess and annoy the neighbors.
2) I have stood outside by the vent while I turned on the DC with a big pile at the floor sweep, and I have not been able to detect anything coming out, and after a year there is no visible build up. That seems like way too efficient for my separator, but that’s my experience.
3) I have no heat or AC, so venting the air out isn’t a problem for me.
4) I got a 4” hole saw and cut a hole in the wall of the shop, and put a 4” metal pipe and exhaust vent

5) I took the DC off the original cart and onto a stand that I made from scrap. I hooked the outfeed of the Thien to the DC, and then use a short piece of flex house from the DC output to the exhaust pipe.

Works like a charm.
