I was initially going to vent inside with twin Wynn Nano filters. The more I think about it I am thinking to just vent outside and forget the filtering. My questions are:
1) is there a "big" loss of heat?
2) venting outside, should it be into a drum?
My heat source is radient hot water in the floor and I will be using a ebay cyclone connected to a Jet 1900 DC. I would then sell my Wynn 1425 filters instead of setting that up and it would save space.
