Questions, Answered

How quiet does a bedroom purifier need to be?

Look at the lowest figure in the maker's published range. Machines here that start at 18 to 23 dB can run beside a bed on their lowest speeds without becoming the loudest thing in the room. A unit whose range starts at 46 dB, like the Medify MA-40, belongs in a daytime room instead.

Should a bedroom purifier run all night?

That is how the published figures assume it will be used: continuous running at a low, quiet speed keeps the room's air turning over steadily. Use the sleep mode and timer or schedule features listed for each model, and keep the intake clear of bedding and curtains so the low speed can do its work.
