My Harbor Freight 2hp Dust Collector "manual" advises to "replace the lower dust collection bag if it becomes torn" but--of course--they/it are/is no help sourcing the bag to do so.

The website represents it as "70 gal."[1] which an online converter tells me is 18816 cu.in. (US, dry) which an online calculator tells me is a bag 20-in diam. x 59.8 in. long. Well, that ain't it. Perhaps HF optimistically means to include the upper cloth bag as well because my calculation of a bottom bag of 20-in diam. by, say, 34-in tall is 39.7 gal.[2]

I think, generally speaking, most of these 2HP bag-over-bag designs use similar bags.

Can someone recommend a source for 6-mil replacement lower bags, in small quantities?

Thank you.

Thank you, Gerry, for doing my homework for me. Again. I had actually searched amazon and ebay (and the rest of the web :^) ) extensively, and even run across these very Powermatic bags, but I failed to notice the comments below, which specifically approved them for my HF model 97869.

I went ahead and emptied my existing bag because I don't want to wait for new ones.

It measures 31"W x 40"H and fits fine, length-wise. I wonder if instead of rolling down the top of a longer 43inch bag, the excess could just be left underneath. I guess there is a danger that it would want to "blow out" initially to one side or another to reach its full-length, but after there was some weight in it, I expect it would stay put. (Or I guess I could put something smooth like a bowling ball in it.)

Heavy plastic. Way heavier than mere "trash bags". A double thickness measures (by pinching outside the bag) 0.24mm=0.0095in, according to a digital caliper, possibly including some microns of sawdust inside. Taking it at 0.010 inch, a double thickness is thus 10mil, implying the (worn) thickness is 5mil. It's possible then that it really is/was a 6mil bag originally.

Here's a good "path" to hunt for them in Amazon at least (I can't fathom ebay's search "algorithm" which seems only to jump on the first word it recognizes):
7 results for Tools & Home Improvement : Power & Hand Tools : Power Tool Parts & Accessories : Vacuum & Dust Collector Accessories : Bags :
"clear 20"

I just searched for "dust collector bags" at Amazon and it came up first.

I've been emptying mine into heavy garbage bags, but I think I've only done it 3 times now, as I don't use it that often.
