Default Fan ventilation - in or out?

Ta.

My brain immediately says 'neither' - or maybe 'both'.

If you have positive pressure that will tend to help keep dust levels
lower by pushing air out.

If you have negative pressure that will tend to draw air, and hence
dust, in.

In either case, if the pressure difference is significant, you might
find opening/closing doors and windows becomes, umm, interesting.

My brain says, have two fans, one pushing in and one sucking out -
balancing each other. If anything, a slight positive pressure.

My brain is probably broken by trying to cope with 30C. :-)

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.
