Some ozone generator vendors do not state vital information on their websites or even products that one needs in order to guage their machines capabilities or even make an informed buying decision.  For instance, most buyers would shy away from the Bio3Blaster if they knew it used almost 900 watts of electricity due largely to the fact it utilized a spa blower instead of a 100 CFM cooling fan.  The blower they use is rated at 105 CFM by the blowers manufacturer, something else me as a consumer would like to know.  I only mention this to show you why it is VITAL to get accurate and informative product specs for any product you purchase, but especially for an ozone generator!  It's already very difficult to make an "apples for apples" comparision of ozone generators without having said specs in hand. 

The ozone generator comparisions below simply provides vendor claims and known specs.  The most important variable of course is the ozone output or milligrams per hour (mgph) rating of a machine.  Since there is no industry wachdog or standard yet in place right now (we're working on it and will have one in place within 4 months, check back to learn more),  what you'll need to do to determine the actual ozone output of the ozone machine in question is to figure every KV of transformer power will create around 1000 milligrams of ozone per hour.  Forget about how many plates or UV lamps, that's meaningless.  If you put 10 plates on a 4KV transformer, from our experience, you'll still only create 4000 mgph.  Period!   Whomever coined the phrase "the devil is in the detail" must have had ozone generator vendors in mind.
