I'm moving my shop and trying to make the new shop as healthy as
possible. I've never seen one of these in action but it looks like
it could be a healthier alternative to my old simple soldering
hood/fan set up.
Karen i would think that a traditional ventilation hood with fume
vented outside would be preferable. If you are concerned about the
loss of heat/cooling then I would suggest that you discuss this with
your HVAC contractor, there are heat recovery units which should
help. This avoids the need for filters which will add to the cost of
running an air recirculating system.
Ask yourself how you are going to test whether the filters need to
be changed, or are you going to assume that they will last for a
predetermined amount of time regardless of usage.
