i have a spare smaller toilettroom...how much new fresh air do i need to transfer to this little room (ca: 0,5x1,5meter area and 1,50 to 1,80 cm height) if to use that instead of my box? the little toiletroom have an outgoing ventilationhole straight up to the roof outside...
any other thing to think of if i am gonna use that ? i am thinking about mounting HSPlamp and the filter with builtin fan directly to the outgoing open valvehole that leads directly up to the outer roof through a channel) in that room if that could work...
