One of the most important things to consider when choosing an air purifier or humidifier is the size of the room. Studies show that people generally buy air cleaners too small for the rooms they plan to use them in. For example, if the room has ceilings higher than 8', you'll want an air cleaner rated for a larger room.

These products are designed for use in small rooms (0-150 sq ft), and for personal use (humidifiers worn around the neck and desktop purifiers). Most bathrooms will fall into this category.
