- Use our "Ozone
worksheet" to create your own comparison sheet,
don't trust the one's that you'll find on a variety of web sites, some give
improper information or fail to include appropriate competitive equipment.
- 2. Output and
- Make sure any ozone generator you consider
purchasing has a "mg/hr" or a "g/hr" output rating.
Any reputable ozone generator company will have had there ozone generators
tested on a photometer. Here at Crystal Air we use a Dassibi 1008 PC ozone
tester that costs about $8,000 - $12,000, the same brand and model used by
most government agencies. Ratings in "ppm" are a simple concentration rating
and do not tell anything about the overall production. Click

video comparisons between our ozone generators and some of our competitors. Our
PRO 4000 is 2.5 times the output of our competitors 4000, our 2800 is 2.16
times the output of our competitors 14,000.
- Be very careful about purchasing any ozone
generator that claims:
- A. "ABSOLUTELY NO
CLEANING OR MAINTENANCE REQUIRED". We have tested several
different brands and models as well as speaking with several of the sellers,
they are either disposable or you MUST purchase costly replacement plates,
or other parts instead of cleaning. These replicable, unclean able plates
cause the ozone production to slowly reduce over time until they finally
stop working. Crystal Air ozone generators are designed to last for years to
come and carry a 6 year warranty to prove it. When maintained properly the
plates will last up to 4 years maintaining a steady amount of ozone
production, the unit itself will last much longer.
- B. or "NEW
PATENTED DESIGN", we have yet to truly see a "new" ozone
generator plate design, they are simply a different ground electrode shape,
mounting design, etc. A plate by any other name is
still a plate.
- -Some companies even try to fool you into
thinking that the patent covers nitrogen oxide and states that they are
nitrogen oxide free. We have researched all such patents that we have been
able to find. WE HAVE NOT FOUND ANY NITROGEN OXIDE
MENTION IN ANY OF THEM UNLESS THEY ARE USING OXYGEN. Click
here to do a US patent search for yourself or insist that the supplier
supplies a laboratory test sheet.
Low grade disposable plastic ozone generators
- Be very careful of the "
small all plastic
ozone generators" that are for sale on various web sites. Most
are a very low grade, very low output, disposable generator. We regularly
receive orders from customers who complain that they bought a small plastic
ozone generator only to find out that it is pretty much useless except for
in the car. Crystal Air ozone generator chassis are built using high grade
stainless steel, the outer cabinet on the PRO series is made from high
impact extruded PVC that will withstand a lot of abuse.
Zero nitrogen oxide claims
- Do not believe claims about corona
discharge ozone generators that claim "zero" or "no nitrogen oxides".
ALL CORONA DISCHARGE OZONE GENERATORS CREATE A SMALL AMOUNT OF NITROGEN
OXIDES" unless they use pure oxygen for feed gas and have
absolutely no steel of any kind in the generation chamber. The amount
produced is negligible, approximately 1/100 of the amount of ozone being
produced. In an ozonated area that is safe to occupy (>0.04 ppm) the
nitrogen oxide level would be around 0.0004, well below the safe level.
- Some companies have used a testing method
that does not work, Draeger gas testing tubes and
Matheson gas detector tubes for nitrogen are not usable in an ozone
environment. Both companies state in their instructions that they
will not give an accurate reading in an ozone environment. Draeger say's
that the nitrogen oxide tests are "not compatible with an ozone environment"
and Matheson states that "the stained layer is decolourized by ozone"
- We have tested our equipment with the
Matheson gas testers and came up with 0 nitrogen oxides, However we know
that, THE TESTS HAVE ABSOLUTELY NO MEANING WHEN
DONE IN THE PRESENCE OF OZONE so we do not claim zero.
- The Draeger and Matheson gas test tubes
use a small glass tube that contains cotton type batting inside that is
soaked in a special chemical regent. The tubes are inserted into a special
pump that draws a calibrated amount of air through it. The regent discolours
up the length of the tube which is marked with concentrations. The problem
is that as soon as the regent changes color it is
bleached or " discoloured" by the ozone and shows no reading,
thus zero nitrogen oxide readings are obtained.
- 6. New
type of air claims
- Some companies marketing ozone generators
are claiming to have invented a new type of air,
such as "a higher form of oxygen" and have given it there own name. Ozone is
ozone no matter what name you stick to it.
- - one claims to make more 04, 05,
06, 07, etc than 03. They fail to mention
in there information that it is a well known fact in the ozone industry that
this is a characteristic of corona discharge.
- Some companies have tried to
copy our PRO series ozone generators, they use a cabinet that
looks similar. The problem is that the cabinets are a much thinner plastic
or aluminium and the components are inferior, usually imported from Taiwan
or? Just checkout the warranty, this will show if they actually stand behind
the quality of the product they are selling.
- 8. How long
have they been in business
- Check how long they have been in
Crystal Air has been in Business since 1993 (13 years). If they
haven't been in business for at least 5 years then it is risky to purchase
from them unless the equipment comes from a reputable ozone supplier, there
is a very good chance that they will go out of business before they reach 5
years and then you will have trouble getting support or replacement parts.
Remember, it is a well known fact that most small businesses do not last 5
Where are they manufactured?
- Be sure to ask where they were built. All
Crystal Air ozone generators are designed and built in Canada, this means
that if you have a warranty problem there will be absolutely no problem
getting I t repaired. BE VERY CAREFUL ABOUT BUYING
AN OZONE GENERATOR THAT IS BUILT IN AN OVERSEAS COUNTRY. Warranty
repairs are hard to get and time consuming if you are able to get it
repaired at all.
- 10. Ozone
- All Crystal Air ozone generators are built
to the highest quality standards, using the highest quality materials. We
use stainless steel and PVC, the only cabinetry
materials that withstand ozone
and do not corrode.
- *Also make
sure that that unit is not made entirely of PVC. PVC will not withstand the
high voltage that is used in ozone production, ALL
COMPONENTS MUST BE MOUNTED ON A STAINLESS STEEL BASE FOR SAFETY.
