How do I know if my air purifier is working?

You can tell if an air purifier is working well if you see debris, hair or dust in the filter, but not enough to completely clog it up. If it's too dirty, chances are it needs replaced. Keep in mind that this only works for HEPA purifiers, as carbon filters won't show any outward signs of aging.
