Anyone recommend where to get one of these? Are they really more expensive than the whole HF unit?
thanks

Wynn Environmental Filters. Model 35a, and they now ship to Canada. This thing comes in a pretty good sized box. Maybe you Canadians can use this?

35A274NANO Cartridge Kit
Permanently closed at the top, open at the bottom with gasket, MERV 15, Nano fiber filter media, 274 sq ft., 17.5″ diameter, 23″ tall, no inner cage.
Included: Instructions, (2) clear poly dust bags, (3) FGL-U latches used for mounting the filter.
Filter price: $188.00. $150 +188 = $338. About the price of a cheapie brand name, 1hp.unit. Wish DC were cheaper, but it sure beats suffering with COPD.
What converted me was an OSHA study that found home shops have the worst level of sawdust particles, far worse than commercial shops. I noticed some breathing problems and decided to set up dust collection. I started building my own setup, but it just wasn't effective and I spent a LOT more that $338 on it. Not only does this put the woodworker at risk, but also for garage shops, the family gets exposed as well. And if you smoke, well, you're just asking for it.
This can be an expensive hobby, that's for sure, but if you're not working strictly with hand tools, do think through the question of dust collection.
