mm, this has been making the rounds of the forum for a few days. i think it’s a nice step for people who feel concerned about venting unfiltered exhaust to the outdoors.
Apologies for the double post.
no no, i don’t think it got its own topic, it’s a neat project worth the exposure.
This is very helpful, especially as it has so much technical information rather than just a how to. And the catchy title makes all the difference!
I like it. It looks like it’s actually reasonably thought out.
I think I was more surprised that the CAN33 filter was cheaper priced Canadian than US (they’re on Vancouver Island) but even so… $140 is definitely a non-trivial hunk o’change. 
We decided to wait and see how the GF filter performed and how much the filters ran and didn’t pick one up in the preorder. This might be a good addition to our “if we never get the GF filter” list at home. Thanks.
