@melanie@bv.umbrellix.org Agreed. The basic 20"x20" box fans available from stores like Home Depot, WalMart, Canadian Tire, Target, etc. are mostly all reasonable. However, when ordering from Amazon or similar, I'd stick to known brands like Lasko, Utilitech, Pelonis, Mainstays, etc. (Some of those are house brands for particular stores, but still good.) All that said, with the way costs have risen on box fans in recent years, they're now the same price in the US as the 5-pack of quieter Arctic PC fans. Wild.
