Keep in mind that exhausting dust collection air outside will not only impact the ability to heat your shop (much like having an open window, which is something not very economical in colder regions), if you are using propane, natural gas or wood/coal for heating, you will also negatively impact the flow of the bad stuff (i.e. carbon monoxide) out of the building with the dust collector sucking make-up air through the heater exhaust. If you are using an electric or heat pump for heating, there can still be a lot of $$ flowing out with the exhaust over time.

I agree on avoiding the bag-type filters and after researching the options, I decided to wait until a canister filter unit was in the budget. I also wasn’t too keen on buying a HF unit and future upgrades.

It might be worthwhile to check out Facebook Marketplace and Craigslist for the option of acquiring a used dust collector. I was lucky and found a new 2hp Grizzly G0458Z Dust Collector with one micron canister filter at a great price. The seller had bought the Grizzly, but before assembling he bought a larger DC at an auction and the Grizzly sat in the corner of his building until he needed the space for something else. He posted it on FB Marketplace for $250 but when we arrived he wasn’t able to find some of the unassembled parts (while he was searching, I checked Grizzly’s website for parts availability and cost – $40) and when he wasn’t able to locate the parts he gave me the machine for $200 (I had the replacement parts installed less than a week later) and it has been a great unit. The Grizzly is $535 new (plus $99 shipping).

I had previously missed a good buy on a Jet DC w/ canister filter a few weeks earlier, so good deals do pop up. The key though is to do frequent and diligent searching because the best machines at the best price don’t last long (I had the Grizzly in my shop the same day it was listed).

My shop is in a 30’ x 40’ x 10’h building, though my woodworking area is basically contained in a 12’ x 28’ area with the rest reserved for my tractor w/ implement, equipment maintenance & metal / general working area and my pick-up when the space isn’t needing for larger woodworking projects. I have a Mr. Heater Big Maxx heater (propane) that does a sufficient job of heating, though it will be much better once I insulate the ceiling area (the only present insulation is 1/2” on the walls). I ran two sections of 4” PVC with two blast gates and flexible hose to my machines on each. I also have a Super Dust Deputy that I have yet to install in my system. I still use my shop vac / Dust Deputy for my sander, router table & scroll saw at my workbench / assembly area, though may plumb that into the main DC at some point in time.
