We have some box fans in the garage. I’ve taken them away from various Young Persons who refused to turn them off when they left the room.
I wear the box fans out. They last about two years, maybe three, depending on where I live. I like them in the bedroom because they cover the outside noises. Like my neighbor and his live-in who sit out on his back stoop (right angle to my building) and let their dog yip and yell. However, the fan doesn’t always cover their noises.
