Good question
Yes, I'm going to have clean air vents in the room as well, so this will be pulling in air from the room in addition to fresh air. This isn't the same as a fan, since it filters the air. My fan just circulates it.
As well, as mentioned, phase 2 will be adding heat. Filtration is only phase 1.
True, it's overcomplicating things. Thats my styleI like projects that keep me busy so that I don't have to watch the bachelorette with my fiance.
