Ozone Generators Suitable for Therapy
Cold Plasma Ozone Generators
The first cold plasma ozone generator was designed and constructed by Nikola Tesla. Plasmafire International, headed by Saul Pressman, re-engineered the first cold plasma generator suitable for therapeutic use by studying an old Tesla model. Today's true cold plasma ozone generators utilize pure oxygen as the input source, and produce a maximum concentration of about 5% ozone.
These generators are sold under the pretense that no heat is generated in production. Cold plasma generators have a very long useable life span, and are good all purpose ozone generators.
However, to quote the enlightened words of Den Rasplicka, owner of the immaculate ozoneservices.com:
So, cold plasma generators are very acceptable. However, it is debatable whether or not such units are superior-- in any way-- to other quality ozone technologies. The retail price for cold plasma generators is usually between $1700.00 - $3000.00 US.
UV Ozone Generators
UV ozone generators are constructed with tube chambers that use the same narrow-band ultraviolet light ( ~ 185 nanometers ) which is responsible for the sustenance of the ozone layer in the stratosphere of the Earth. The ozone layer is created by the bombardment of the Earth's atomosphere by the sun's radiation.
While standard UV ozone generators are more affordable, nearly all of them produce ozone at a 2% concentration or less.
Benefits: No nitrous oxide produced, therefore pure oxygen is not required. UV is the cleanest way to produce ozone. UV Ozone generation is the only ozone generator technology that produces Hydroxyl Radicals ( OH-)
Down-sides: No standard commercially available UV generators can achieve the minimum 5% concentration required for true therapeutic value ( we can now custom build an ozone generator for interested parties that produce 5% ozone ).
"Hot Spark" Corona Ozone Generators
Many variations of the "hot spark" coronal discharge method of ozone production exist, including medical grade and industrial grade ozone generators. However, these units CANNOT be used without 100% pure oxygen for therapuetic purposes, due to the high levels of nitrous oxide produced by the machines if fed with any "normal" air.
Ozoneservices.com offers the best high quality medical grade generators for experimental research use. However, full kits can be expensive, as the ozone generator itself costs a minimum of $1,400.00.
Benefits: Excellent for medical facilities with oxygen supplies and professional staff. "Hot spark" corona discharge machines are perfect for all medical applications If you buy from the right manufacturer.
Down-sides: Heavy maintenance is often required, especially with the lower quality units being sold ( with high price tags ); pure oxygen is required for any use in therapy. Quality units can be expensive.
"Cold Spark" Corona Discharge Ozone Generators
To our knowledge, the cold spark method is a relatively new engineering method. The cold spark method utilizes the same principle as the hot spark method, but the chamber is completely isolated from the spark which is responsible for the majority of nitrous oxide produced with the hot spark method. The result is that almost no ( ~ 0.003 PPM ) nitrous oxide is produced when using ambient air. This makes these machines safer to have around, even though, when using cold spark generators that produce concentrations above 3%, they must still be oxygen fed.
Why do they call them cold spark generators? Simply due to the fact that a spark is still used in the cells which produce the ozone.
Benefits: Cost effective engineering. A properly engineered product, with high grade components ( not the cells coming out of Tawain and China ) will last a minimum of five years.
Down-sides: While suitable for therapy purposes, many of these units cannot be said to be "medical grade", and some do not produce therapuetic levels of ozone. There are many variations of this technology available. Many of the cold spark units are very poorly designed and have a very short production life. Most of these units cannot produce a high enough concentration of ozone. Be certain that you research any model carefully before investing to ensure that therapeutic levels of ozone are actually produced.
Other Ozone Generators and Technologies Not Suitable for Therapy
PEM - Produces ozone using a polymer electrolysis membrane. A correctly engineered PEM unit can produce up to 20% ozone concentration ( by weight ) in water.
This is the newest method of ozone production, and the process is incredibly clean. No air or oxygen is required in the feed, as the units create ozone in purified water.
This technology shows the greatest promise for applications that require ozonated water.
Tabletop Water Ozonators
Ozonators such as the "Nature Kleen" cold spark ozonator, which produces ozone at a rate of 250 mg/hr., are very nice to have sitting in the kitchen to ozonate a glass of water or even ozonate fruits, vegetables and meat. However, these units do not produce NEARLY a high enough concentration of ozone for use in sauna therapy, bagging, or for other true therapeutic purposes.
The cold spark units that are engineered well sell for just under $300.00. Poorly manufactured units sell for as little as ~ $80.00.

Calculating Concentration of Ozone
It can be confusing to calculate the true ozone concentration based on different measurements used by different companies. Here is a general guide on converting concentrations:
