This came up in Drew's thread and Rennie was interested. So am I. Where on the ceiling?
I am thinking the floor plan has a part to play as well. I am drawing house plans and laying out electrical needs, so this is relevant. In Nevada the big (600+ SQFT) garage was a squarish rectangle. I put the air cleaner on the ceiling against one long side wall and it worked real well there. Also was not in the way of swinging boards, etc.
The new shop is longer and more narrow so I am now wondering if that will still work. It is an attractive idea for a number of reasons, not the least of which is aesthetics. My basement shop will have 8' ceilings, so cluttering up the ceilings will large objects contributes to the claustrophobic feeling of a cave, though it will be brightly lit. I don't want to go higher with the ceiling because I am already flirting with a looming exterior effect of a two story house on a tiny lot. And the next owner may not use that space in the same way.
Heating is not an issue for me, so I am unconcerned with combustible air and possible air starvation of a furnace or stove. I wil have a small propane furnace for the house but the combustible air will come from the outside. Most of the heat will come from solar heaters.
So what thinks the brain trust with regard to the location of an ambient fine particulate air cleaner in these circumstances?
