Buying Guide: Smoke Protection for Less
Keep these points in mind before you buy.
Pick a high smoke CADR
EPA says to remove small particles, choose a purifier with a high CADR for tobacco smoke, which represents the smallest particles, sized for your room.
Set up a cleaner air room
EPA suggests one room where people spend time during smoke; one air cleaner may be enough for that room, or you can move it room to room.
Count the filter cost
Check the price and life of the replacement filter before you buy. A cheap purifier with expensive filters can cost more over two years.
