Dunno what your setup is for air exchange etc. but, you don't even need the filter yet. MY stuff runs 24/7 but I didn't add the filter until just before flower.

Looks fine , but if you mean leaving fans on , then yes .

I thought u had to keep filter on for the air to change it even tho there so tiny.. just wanted some advice from more experienced growers

The fans are your air exchange, the filter is for stink. I'd keep the fans going in a tent at lights out.

so leave oscillating fan on and turn filter off

I've been running filter as it keeps temp down

they need fresh air the exhaust goes through the filter.
