Air "Purifier" Warning

[Chuck Guzis]

For those of you who get Electronic Design, check out Bob Pease's column in the current (September 29, 2005) issue.  It deals with the mayhem that retail "air purifiers" can wreak on rubber hoses, drive belts, pinch rollers, seals, etc.

Basically, these things are high-voltage corona generators whose "activated oxygen" output is nothing more or less than ozone.  Yup, the same rubber-rotting ozone that's death to rubber.

Maybe it's a good idea to steer clear of the things. 

Cheers,
Chuck
