Short answer: look at what the ozone cell is made of, whether the output is calibrated in µg/ml, what gas it needs, whether every part the ozone touches is ozone-safe, and what the warranty covers. Words like "professional" and "high output" on a listing tell you nothing on their own.
1. What the ozone cell is made of
Ozone is a strong oxidizer. If the gas touches ordinary metal on its way out, the metal slowly oxidizes and that ends up in your output. A quartz glass cell keeps the discharge away from metal.
Ask: is the cell quartz, and does the ozone touch any metal before it leaves the unit?
2. Whether the output is calibrated
Ozone concentration is measured in µg/ml (micrograms per milliliter). "Adjustable output" without numbers means the unit has a dial, not that the dial means anything. A calibrated unit comes with an output chart: for a given setting and oxygen flow, here is the concentration you get. Without one you can't repeat a result.
Ask: does it come with a calibrated output chart, and over what range? See what µg/ml means on an ozone generator.
3. What gas it runs on
Ozone is made from oxygen. Room air is about 78% nitrogen, and running air through a corona discharge also makes nitrogen oxides. Units built for pure oxygen, from a cylinder or a concentrator, make clean, higher concentrations. Only feed a generator the gas its maker specifies.
Choosing a source: oxygen tank or oxygen concentrator? and what you need to run an oxygen-fed generator.
4. Whether every part the ozone touches is ozone-safe
Ozone breaks down most rubbers and many plastics. A unit with a good cell can still deliver contaminated gas if the tubing or fittings perish. Look for silicone or PTFE tubing, 316 stainless fittings and an ozone-rated diffuser. The details are in ozone-safe materials.
5. What the warranty covers
The ozone cell is the part that ages. A one-year warranty on "the unit" is worth much less than lifetime cover, and cover that transfers to a new owner keeps its value if you sell the generator.
Ask: how long is the cover, which parts does it include, and does it transfer?
6. Who made it, and can you reach them
A generator lasts years. Buy from someone who builds the unit and answers the phone when you have a question.
Checklist
- Quartz cell, no metal in the gas path
- Calibrated output chart in µg/ml
- A clear feed-gas requirement, and a matching regulator
- Silicone or PTFE tubing, 316 stainless fittings, an ozone-rated diffuser
- A warranty that says how long, what's covered and whether it transfers
- A maker you can contact
How Synergy generators measure up
Synergy Ozone Generators has made ozone generators in the USA since 2005 and sells them direct.
- WPS-100: a quartz glass cold corona tube that does not touch metal, up to 80 µg/ml, oxygen fed, 100-240v.
- WPS-120: a quartz cell, 8 to 128 µg/ml with a calibrated output chart, 316 stainless luer lock connections, components A-rated against ozone degradation, lifetime warranty on all parts and labor.
Every Synergy generator has a lifetime transferable warranty. Questions? Call or write to us.
