In fairness, circulating air in a castle whose geometry is best represented by an arbitrarily connected graph (not necessarily acyclic), is a non-trivial engineering challenge. After a few student asphyxiated, they may just have gone a little overboard.
I now declare this to be MoR!canon. (That large magical dwellings in general have large highly-connected, possibly magical air-ducts, by tradition, to prevent the occasional cases where somebody asphyxiated; and that Salazar used this as his excuse for why Hogwarts’s ventilation ducts had to be so large.)
Aguamenti creates water out of nothing, which you can drink. The Bubble-Head Charm could, in theory, work some way other than creating thin air out of thin air, but personally I doubt it does.
I never, in Canon, got quite such an impression of Eerie Alien Geometries from the castle as I do in MoR. Thankfully Event Horizon hadn’t come out in 1991, or I’d wager a lot of Muggleborns would be very uncomfortable in the upper floors.

Ha!
I initially wrote ‘create breathable air out of thin air’ and then couldn’t resist.
