When researching ozone generators on the Internet, customer may ask how is the ozone output measured for ozone generators?  There is no coordinated way to measure ozone, so the manufacturer claims are often quite bold and often misleading. 

According to NOAI, the correct way to measure ozone output is accomplished with a pure oxygen feed of the ozone cell.  Pure oxygen obviously provides a rich supply of O2, which is converted to O3 (ozone).  If the output is properly measured, we can rate the ozone cell accordingly.  This information is primarily critical to those using medical ozone that is generated in smaller quantities.  

Let's return to the real world of sanitizing rooms and building, destroying odors embedding in homes, killing mold in a building, or detoxifying a sick building.  The gross volume of air that is measured in tens of thousands of cubic feet, cannot be supplied by a very limited volume of pure ozone from bottles or an oxygen concentrator.

So, these large, non-medical applications use ambient air in the building.  We do not have pure oxygen in our shared atmosphere.  

• Ambient air typically consists of 78% nitrogen and 21% oxygen. The
  extra 1% is a combination of carbon, helium, methane, argon and hydrogen.

So, the rating of 30,000 mg/hr ozone output by an ozone generator is its "Pure Oxygen" output.  The actual output in ambient air is roughly 21% of of the pure oxygen output.  That means that the consumer can expect 6,000 mg/hr of ozone from listed ozone output power.  

Before you get deeply concerned about this level of output, 6,000 of "Actual Ozone Output" is very powerful.  

At Professional Ozone, we promote the XPRO-1000 at 1500 mg/hr, th XPRO-2000 at 3,000 mg/hr, and the XPRO-4000 at 12,000 mg/hr.  But, we are listing our true ambient air output, not the rating we would get at 100% oxygen feed.   We believe that this kind of honesty will be something our customers appreciate.

So, the XPRO-2000 rated for 3,000 mg/hr of ozone output with ambient air, is probably more effective than 20,000 competitor, but there is more to our ozone equipment.

Cold-fusion is a reference is the difference between metal screens and plates surfaces or electrodes sealed behind pyrex glass.  Professionals have come to the opinion that cold-fusion ozone is actually better than metal electrodes.  Metal surface eventually wear our, and the the ozone quality is less effective.  Some say that cold-fusion ozone is a sweeter-smell ozone and seems to do a more effective job.
