ALEN BreatheSmart Flex for bedroom
I have an Alen 35i, which is a smaller and newer model than what you’re looking at. It runs very quietly for the bedroom. This brand is pretty high-end, though, and if you’re not picky about which boxes need to be checked, you can certainly find something cheaper that filters the air equally well.
