HEPA filter clarification
    #10292441 - 05/05/09 06:49 PM (14 years, 10 months ago)

Looking at getting a HEPA filter with which to build a hood.

Any idea if filters with collars on the back for attaching duct work to, apparently for use in ceilings of clean rooms, are appropriate/useable? Uncertain if that part is removable, or if it even matters that it is on there. Seems like if air was being pumped through a duct to that point in the filter and it still managed to produce laminar flow, it should still be reasonable for the positive pressure in the box to basically have exactly the same effect, right?

first off, it is not a laminar filter, it is designed to blow air in every direction, and the duct would have to be removed and a LARGE plenum built, and you'd have to buy a POWERFUL fan for such a large filter. (ceiling clean room filters  are standard 24x48)

Best bet is to use one of the laminar filters designed specifically for flowhoods from fungi.com
