   Do not know any details of the Honeywell unit, own house has an old sears filter.

   Anyway, as to factual - you asked for it:

   Ozone (O3 vs atmospenric O2) is produced by partial ionization of oxygen molecules in the air when corona is present. Corona being present means that a partial discharge of the air in your air cleaner is occuring (typically a faint blue glow vs a crackling arcing).  Usually the air cleaner design is such that there is an electric field strength between the wires and plates in the cleaner that wil pull dust particles to the plates without corona (a precursor to arcing) being present.  A number of factors could come into play here.  If you live in Denver or other high altitude area, the breakdown voltage of air is lower than in LA or Tampa for instance, and you are getting continuous corona and that could be the cause of the ozone.. I recall Winnepeg (thanks for posting a profile, that helps) is on a low plateau at only about 1000 ft (300M) so simply being at a high altitude with less dense air is likely not the cause; however, is the ozone more prevalent when the barometric pressure is really low?

   The other possibility is to look for a deformation in the air cleaner unit where a plate and wire are closer than other places -- may be producing ozone 'cause one of the plates is bent.

   Paul,

    I dont know if your Honeywell is the same as mine but ... if you have the instruction book, mine has a jumper on the cirquit board that you can move to lessen the ozone effect. It has three different settings.

   Hope this helps,
