How Many Air Cleaners Do You Need? effectively clean your indoor air pollution?

Find out how many and what size air cleaners you need for your application.  Effectively cleaning your indoor environment depends on:

  1. How much air pollution you have (Heavy, Medium, Light)
  2. How big your space is you are trying to clean
  3. How much air can be moved through your air cleaner (we call this CFM - cubic feet of air per minute)

To help you figure out which air cleaners you need or if you need more than one air cleaner, we have built this Air Cleaner Calculator so you can easily determine how many of which size air cleaners you need.
