A question for the non-smokers.
My upcoming MVHR install, in an apartment, has only two possible places where the outside air intake can go:
Within 1m of an external landing, where people sometimes smoke - and the smoke will sometimes get draw into the inlet. This option would have a short intake pipe, but a significantly longer exhaust (x 4).
Within 1.5m of the top of a neighbouring SVP - and the smell from that will also sometimes be drawn into the inlet (not so often, but for longer). This would reverse the pipes - a short intake and a much longer exhaust.
Due to space restrictions, the exhaust can only go in the other location to the intake, so I have to decide between a choice of smell-source vs exhaust pipe length. The pipes will be well insulated, but can only run through the ceiling space.
In theory either smell should be eliminated by the carbon filter that I'll be installing, and if so I have a preference. But has anyone got experience of how well either smell gets filtered in practice?
