Ken, I couldn't agree more.  Odor masking fragrances just compound the problem.  And ozone generators and negative ion generators put ozone in the air at levels that are hopefully so low that they are ineffective at breaking down odorous organic chemicals because ozone is toxic.  Ozone has the same 0.2 ppm TLV that phosgene has.

Find the odor source and get rid of it or exchange the air fast enough to dilute or exhaust the contaminated air.

Odor eliminator or odor masker ?   Not referencing this product at all, but as a general point when  I hear "air freshener" I think of "air polluter".We had a speaker from a department on campus providing small and inexpensive hangup "air fresheners" as a gift to the attendees at a presentation. I was obliged to ask them to not use them here and think twice about using them in their cars and home.. or at least do some research first.
