I was wondering if anyone uses an air purifier for their home? I live in LA and my 1 bedroom apartment is carpeted. The apartment can get stuffy most of the times and we face a major intersection so we don't leave our windows open a lot. Our baby is due next month and I'm starting to get concerned that the air quality in our apartment might not be good for him.

Do you recommend using an air purifier? and if so which one?
