Topic tags/keywords: air cleaner wen placement

Just got a wen air cleaner for the garage and I’m trying to figure out where to place it.

I only have two circuits to the garage and while I know it’s not an ideal location, this spot allows me to plug it in on a different circuit from the one my power tools will be on.

Originally I had the filter facing out with the clean air blowing against the wall, but rotated it to the orientation it’s in now. In this spot is it really doing much? Or should I try to mount it elsewhere and run an extensive cord.

I have mine (not your brand) placed approx. 1 1/2’ from ceiling midway a long wall. Air intake and exhaust parallel to wall. Helps create a somewhat circular air flow in the shop. Works well for me.

These filters are just fans, with some filters attached in front and back. Like Bill said, they will produce a flow of air around the shop. You’ve already recognized that you want it to be in a spot where it is likely to draw in the most dusty air. You then want it to have a decent exit path to push air out into the shop space. I lean to using the extension cord and getting the best flow location you can.

Mine (also a different brand) is in the middle of the shop ceiling in one direction, and about 1/3 of the ceiling span out from a wall in the other. My ceilings are only 8 ft high. It seems to do a good job there.

I taped up some little paper tell-tales in several spots around the shop so I could visually observe the air flow in multiple places. When I turn on the filter, I can see all of them flutter and move.

And I add that one of the key factors is you need to be able to use the controls, directly or by aiming the remote at the right place. In reality, I would sort of like to turn mine around to reverse the air flow path around the shop. But doing so would mean the control panel was on the “back” side, nearer the wall, where it would be quite difficult to use.

I heard the ideal is to have the unit located about 1/3 the length of the space with the air intake on the 1/3 side and the output on the 2/3 side. I’ve heard of this circular flow by putting it near one wall. I don’t believe it matters, but someone on LJ says they read something showing it did. Mine is in the middle (side to side) and it of course creates flow on both sides of it.

The air coming out of these units forms a column of air that will blow out toward the other end of the space. The intake however draws air from all directions. Get just a short distance form the intake and you won’t feel any air movement. This is pretty much like any fan works.

My point is blowing out the stirs the air farther away than the intake does. So placing the unit nearer one end and blowing out would seem to be a better way of stirring things up. However, I have no proof this is actually better.

In your case, I’d turn it around and get those ice chests out of the way. Or just move it out in the middle and use an extension cord to plug it in wherever you want.
