Do you have any recommendations for a room humidifier for my houseplants during winter? And , could you please tell me what makes purple leaves turn reddish and die on a purple heart houseplant? Thank you very much.

A humidifier would definitely help them out. It isn't completely necessary for them to survive, but they will be much happier with it. I believe this to be the cause of the issue with your tradascantia, also. The leaves sound like they are beginning to dry out. Just a small dehumidifier would be enough to keep them happy.
