I don't know which position will have a \"better\" airflow.","acceptedAnswer":{"@type":"Answer","text":"I have several of these and I could not disagree more about a central location install. Put this where you create most dust PERIOD. The main dust created from your work should be able to easily float right up into to the air scrubber, If that's your miter station you set it right over the miter station. This gets hung from the ceiling not on a wall. If you place this in the center of the shop or room it's going to try to pull that dust to the center of room and there may not be any dust ether to begin with why pull dust through the shop if you dont have to?I have one over my Miter station, one over my Band Saw and the third larger unit in the center of the shop. But if I only had one air scrubber that thing would be wherever the majority of my dust is made, not just in the center or in an arbitrary corner.And always by a few smaller units than one large unit, I made that mistake initally. If you can afford the big version of this just get two of these smaller units and put each one over the ares you create the most dust."}},{"@type":"Question","name":"It says must be mounted 7feet off floor. Is this just for safety? Are is it for proper operating of unit?","acceptedAnswer":{"@type":"Answer","text":"I never saw a notice to mount it a minimum of 7 feet off the floor. Mine is mounted about 1.5 feet down from a 10 foot ceiling so with the height of the unit makes it about 7+ feet off the floor. It is mounted over a workbench so there is no danger of hitting it with work pieces moving around, but it seems like the right height for the unit. I would think that you could mount it at any height that would make sure you don't hit it with moving your work pieces around. As for operating the unit, it seems to me that the closer you can place it to the source of dust and airborne particulates, is the best place to mount it."}},{"@type":"Question","name":"My shop is 27x27 with 20 ft ceilings. Will this unit filter the air efficiently in such a large space?","acceptedAnswer":{"@type":"Answer","text":"Could not say for sure but a couple of comments to possibly make it more effective. if you could possibly hang the unit well down from the 20 foot ceiling and position equipment that generates significant dust in closer proximity that should compensate for the large space. I have not put my unit to the test so far to give you a better feel for cleaning capacity but my 13 X 14 shop opens up to a basement storage area o that would make it a similar size to a 27X27 with about a 9 ft ceiling. So far I have not noticed any excessive dust in the storage area but again i have not really pushed it enough to be conclusive."}},{"@type":"Question","name":"Does anyone know why this the prefilter is described as \"electrostatic.\" There appears to be no electrodes or DC voltage supplies internally.","acceptedAnswer":{"@type":"Answer","text":"Here's the answer to how electrostatic filters work (from eHow.com) -- \"The secret to the electrostatic air filter's effectiveness is the polyurethane and polypropylene blends used in the filtering material. The fibers have been formulated so that when air passes by them, they generate strong static charges. Separate layers of filtration material also receive opposite charges (positive and negative). Since positively charged particles are attracted to surfaces with negative static charges and vice versa, the filtration media can actually attract airborne particles like a magnet and hold on to them until the filter is cleaned. When a particle of dust, mold, fungi or any other airborne matter comes from the HVAC system and through the ducts toward the filter, it first passes through a synthetic filter layer with a positive static charge. This positive charge gets transferred to the airborne particle. Then the particle passes through a layer with a negative charge, and it is attracted to that layer's surface. The more layers of oppositely-charged filtration media there are in the filter, the more effectively it can prevent airborne particles from entering the room.\""}}]}]}
