Guest guest Posted March 12, 2006 Report Posted March 12, 2006 On my hepa filter aircleaners I am told in brochure the odor carbon ring lasts for six months. I can tell when they are going. Janet Quote
Guest guest Posted March 12, 2006 Report Posted March 12, 2006 Carl, so you can tell when charcoal needs to be changed when it has a smell? I always wondered how to tell if charcoal needs to be changed, as you can't tell when it is 'dirty' as you can with white particle filters. --- In , " Carl E.

Guest guest Posted March 13, 2006 Report Posted March 13, 2006 Glad you answered for both. I think many use the masks thinking they are protected - as in absolutely - for as long as they intend. A few hours is about their limit because there is very little charcoal in them. 6 months for the filters is about right, especially for someone as sensitive as you are.
