Have you got your trickle vents open on your windows? That might be enough to stir the air. As soon as you said clothes dryer I knew that’s what it’d be.
Can I offer a bit of advice? If you’ve got the room for one get yourself a heat pump tumble dryer, we got a sub £400 Beko one a few years ago costs us about £30 a month to run with 2 adults 2 teens plus pets so it gets used a lot, every day for sure it’s so cheap to use vs a condenser dryer that it’s more efficient than a clothes horse.
