– CONS


– O2 flow is given in L/h (liters per hour) instead of the more common LPM (liters per minute), so some calculation is required

This machine is something else.

It took me a while to understand what I was dealing with here. I had to experience professional medical ozone devices like the German Zotzmann, Herrmann, or Humares machines in order to catch on that the Ozonette is not your average consumer ozone generator.

This machines doesn’t really belong on this list. Together with the ones I mentioned above, it belongs into a different class of ozone generators.

For one, it has the highest quality certificate of CE IIb which all medical ozone devices in Germany have to fulfill.

It is a dual dielectric ozone generator, something unheard of even among the best German generators. This means that both metal electrodes are shielded from the ozone stream by an insulating material, in this case glass and ceramic.

It has a built-in ozone analyzer, so the machine checks if there is a discrepancy in the O3 output and issues a warning if there is.

The ozone output is not regulated through the O2 flow, you can directly choose any O3 concentration you want on the machine.

If you want to administer ozone modalities which call for a continuous gas flow like insufflations, you can do that, too. In which case you can additionally set the oxygen flow down to ⅙ LPM.

Or you choose the manual option which gives you full control over ozone concentration, oxygen flow and amount of ozone.

So you can do everything: you can fill syringes for any type of injections, or for major autohemotherapy, you can hook up a line and perform insufflations, or ozonate water. You can set your ozone concentration and oxygen flow, and it will calculate the ozone dosage in mcg for you.

It is self-calibrating, has a built-in oxygen regulator, and it has a perfect ozone range which true medical devices have: they go to max 80 mcg/ml. More than that and you are running the risk of damaging red blood cells.

SimplyO3 offers a wide selection of ozone accessories and ozonated oils in its online shop.

Summary: This machine is a class of its own. If you are an ozone practitioner or a true OG, ozone gangsta, and only want the best for your money, this is the machine to splurge on. The next comparable O3 generator would be a German model for around $2,000 more.

If you’re looking for an ozone generator of great quality then you can’t go wrong with a machine from Longevity Recources.

The Canadian company has been making high quality devices for over 21 years. I personally have seen Longevity ozone generators in the offices of four different medical doctors in the US. Their machines are dual dielectric which means that the gas chamber in which ozone is created is made entirely of glass, guaranteeing the highest purity possible. They say that they are the only manufacturer of ozone generators which have only 100% ozone resistant materials in its path, without any metal components.

Longevity is very proud for being the only North American ozone equipment maker which is supported by the American Academy of Ozone, presided by Dr. Frank Shallenberger, one of the foremost ozone therapy pioneers in the US.

What is important to note that despite its medical chops, Longevity generators are not certified medical equipment. They are officially sold as water purification devices.

Recently, Longevity Resources has implemented a few changes: their most popular ozone generator EXT120 now comes with a digital potentiometer, the ozone concentration is adjusted not via a dial knob, but by pressing on up and down arrows. For $205 extra one can have an all digital model with a built-in timer, the EXT120 T “Ultra”.

Both models are powerful ozone machines with a maximum ozone output of 120 ug/ml at the lowest flow of 1/32 LPM. You can do anything with them: from ozonating oil, ozonating water, to insufflations or saunas. Longevity says its machines are made to run 24/7 without risk of burn out. Ozone professionals use them also for invasive ozone therapies like IVs or various forms of injections.

One possible downside to buying from Longevity is the lack of an online shop. Every order is processed on the phone. You can ask for a current price list which does not come with pictures of all the equipment, only a select few. If you’re new to ozone therapy and do not know which equipment you need for which ozone modalities you can quickly find yourself spending a few hundred to a few thousand dollars more than you anticipated after talking to the sales personnel. On the other hand, if you don’t mind spending extra money on ozone gear, but in return know that you will receive the highest quality possible from one place, then Longevity Resources is the right company for you. They will always give you kind and thorough phone and email support, and give a lifetime warranty on the quartz glass chambers.

The generators do not come with any extras besides one foot of tubing and quick connectors attached to its oxygen and ozone ports.

Longevity Resources does not give any discounts.

Once you bought a Longevity generator you can apply for a referral program and be paid up to $150 per newly generated sale, but not before.

The EXT120 T “Ultra” allows to set a specific time for the production of ozone. If for example you want to ozonate your water for only 30 min, then you program the timer accordingly and the machine will turn itself off after the 30 minutes have expired. One can also choose seconds and hours as units.

Both EXT120 and the EXT120 T “Ultra” come with universal voltage, which means that they can run on any power supply anywhere in the world, from 110 to 240 V.

Summary: Longevity Resources is a well established company which has been on the market for over 20 years. It is the only company which produces all glass ozone chambers. It has recently upgraded its best-selling EXT120 model which now comes with a digital “dial” and a built-in timer (“Ultra” model).

I absolutely love this company: Promolife has been selling ozone gear since the 90s. If you followed them for some years as I have, you will recognize one of their most striking features: how readily they respond to their customers’ needs and even seem to anticipate them.

You bought an ozone generator at a yard sale and would like to know if it still works properly? Not a problem: Promolife has the solution: the Ozone Generator Testing Service.

You live in the UK or the EU and can’t buy a pediatric regulator which would fit your UK or EU tank? Not a problem, Promolife has the solution: a regulator which will fit onto a UK tank. Or get an adapter.

You don’t want to spend extra money on a humidifier AND a water bubbler? Not a problem with Promolife: just buy the Ozone Water Bubbler/Humidifier Combo. It allows you to ozonate your water without creating excess ozone in the room – all you need to do is attach the destructor unit. Or you can use the same glass bottle as a humidifier – all you need to do is disconnect the destructor and connect the bubbler to an earscope or catheter. E voila!

Not to speak of the new hard-shell sauna, now back bigger and badder. Or the build your package service, or the all-Teflon earscope, or the ozonated oil suppositories, or the glass syringes with luer lock fittings. Promolife always comes with new exciting stuff, always reaching out to its customers, seemingly eager to fulfill each of their ozone dreams.

That same mind set seems to have been applied to their line of ozone generators.

The O3Elite Single Stage ozone machine is a small, light, quiet ozone generator. It is the perfect ozone device for home use. If your main goal to get an ozone generator is for personal health care purposes, this generator offers all you need.

Both ozone generators (the O3Elite Single Stage and the O3Elite Dual Stage) are endowed with little details which show how much thought and care went into their design. The ozone output dials are elegant metal knobs with a smooth feel to them and a subtle “click” when the output is turned off. The oxygen in and ozone out connectors are luer lock attachments which come with caps to protect them from dust if you don’t use them. A luer lock is like a little screw. Once it’s connected, you don’t need to worry about it accidentally getting loose. It sits airtight.

The generator comes with a number of extras, including additional luer lock and quick connectors so you can easily attach anything from humidifiers to catheters.

[A drawback of the Single Stage, as opposed to the Dual Stage, is the missing chart on top of the machine. It only comes with a printed version]. – SCRATCH THAT!! The new single stage machines come also with a chart printed on top. You have one of the old ones? Contact Promolife and ask them for a chart and they will send you one.

Here a video by my friend Teresa Caballero how to best attach the new chart on top of your chartless single cell O3Elite.

The O3Elite Ozone generators are unique: they use ceramic in their oxygen gas chambers. They are single dielectrics, which means there is ceramic on one side of the ozone chamber and an aluminum oxide electrode on the other side. Both materials are highly ozone resistant with aluminum oxide being approved even by the most stringent German industry standards and ceramic being used in high powered industrial grade water ozonaters and being known for their high ozone resistance.

Another great extra feature of the machine are the different electric plugs: whether you’re in the US, EU or UK – you just select the corresponding plug and can start insufflating yourself internationally. No transformer necessary and you don’t have to worry about accidentally damaging the machine with too high voltage. This, plus its light weight makes it the perfect ozone generator for traveling.

Are you still concerned about a possible contamination? Buy a line filter, also available at Promolife.

Another great thing about the generators is that they can be completely cleaned. Should you accidentally get water into the chamber, just run oxygen through it.

Oil is a little more complicated matter. One should always take careful precautions not to get any oil inside an ozone generator. The simplest and best solution is a trap.        

The single components of Promolife generators have various quality certificates, the ozone generators themselves, don’t.

I absolutely love Promolife. And not only because they send me a bunch of free stuff (thank you guys!), I’ve actually had a crush on them for a number of years. Ever since I learned about ozone therapy, I’ve been ogling their ozone products and salivating over them. But I, often living on a super low budget, could rarely afford them. “One day, I will get one of their glass humidifiers” I used to dream. Some people dream of a new Mercedes, I was dreaming of Promolife ozone gear.

I’ve had one of their generators, the O3Elite Dual Stage, for a number of months now and I am surprised by how much I like this machine. I use it for anything from insufflations, making ozonated water to ozone IVs. Just like the Single Stage, this machine is small, light, quiet and elegant. You can tell how much love and care Promolife put into designing both generators. There is thought behind every detail. It has the same elegant ozone output dials with a smooth feel to them which make a subtle “click” when the dial is turned off.

The Dual Stage is so-called because it has two ozone chambers. The oxygen goes through two stages of electrification: it first is subjected to an electric field in one chamber, and then if the resulting ozone concentration is not enough, you can turn on the second chamber to achieve an even higher ozone concentration.

Each chamber can be used independently. You can choose to use just one cell so that you essentially have the output of the O3Elite Single Stage ozone generator. If you use both cells, you increase the ozone output up to 120 ug/ml. If you’re thinking about making your own ozonated oil, this machine will help you save time.

Both O3Elite ozone generators have a number of characteristics in common:

They come with luer lock attachments with caps to protect them from dust. Thanks to the luer locks you do not need to worry about your tubing getting accidentally disconnected by pulling on it. The connectors sit air tight.

Both chambers of the Dual Stage are single dielectrics with ceramic and highly ozone resistant aluminum oxide. The ceramic chamber assures low heat and hence a stable ozone generation.

They’re cleanable: If water enters the ozone chamber you just run oxygen at 1 LPM through it and the machine can be operated again. Oil is a little harder to remove. Great caution should be taken to not allow oil to enter. Best solution is a trap.

They come with multiple electric plugs, so that the machines can be used with a variety of voltages and plugs. Damage due to accidentally subjecting it to a too high voltage, is virtually impossible: you just select one of the adapters which come with the machine.

One of the features I’ve been enjoying the most is the ozone output chart on top of the O3Elite Dual Stage Generator. The Dual Stage allows for around 50 different settings between the oxygen flows of 1/32 to 1/2 LPM. Thanks to the chart you don’t have to look at a separate output chart while you operate the machine. You can verify the correct setting just by looking at the machine.

Promolife generators do not have a any quality certificates.

Summary: Quiet, light, durable, and very powerful, there is little this machine cannot do. From luer locks, to the cleanable cell, to the multiple electric plugs – this generator has been designed to make its use as convenient as possible for you. If an “all-glass” machine is not a priority, this model will fulfill each of your ozone wishes.

 

5. Longevity EXT50

“Most affordable all-glass unit on the market.”


 US$ 995

65 mcg/ml


 

 

+ PROS


– all glass ozone chamber
– light weight
– ETL approved and backed by American Academy of Ozone
– found in many doctors’ offices
– lifetime warranty on glass chamber
– low EMF
– many quality certificates

– CONS


– no online shop, orders are placed on the phone
– no discounts
no extras

exclusively for visitors of the Power Of Ozone website until 31st of October 2017 every ozone generator comes with the following:
– 6 Feet of oxygen tubing
– 6 feet of Ozone Tubing
– 8 Pairs of Quick Connectors or Luer Connectors (your choice)
– Ozone Output Chart
– Two free ‘recalibrations’ service valued at $100 each  

The EXT50 is a classic. It is a bare-bones, simple, and beautiful machine. It is the most basic generator Longevity sells which has been recently upgraded to make it even more attractive. The maximum ozone output at an oxygen flow of 1/32 LPM used to be 55 mcg/ml, now it has been bumped up to 65 mcg/ml.

At US$995 the EXT50 is the most affordable all-glass ozone machine on the consumer market. Longevity sources pride themselves for producing what they claim is the purest ozone production: there are only highly ozone resistant materials in the ozone path and no metals. Something which many home users value a lot. Many people feel overwhelmed by the different types of ozone generators and different claims about quality. Longevity puts those worries to rest.

I’ve had an EXT50 for around 4 years now. I’m very happy with the machine. I decided to buy it because I wanted to have peace of mind when giving myself ozone intravenously. I wanted to make sure that the ozone going into my body would be free of any possible contaminants, and I felt that a Longevity generator could provide that.


The machine itself is small and very light-weight (it has been recently made even smaller). It can be mounted on the wall, although I personally prefer to keep it on a little side table.

The EXT50 is regulated entirely by the oxygen flow, there is no dial knob. The lower the oxygen flow, the higher the ozone concentration. The higher the oxygen flow, the lower the ozone concentration.

There is around one foot of each PVC and silicone tubing attached to the ‘oxygen in’ and ‘ozone out’ ports. One can choose between quick or luer lock connectors. Other than that, the machines comes with no extras. Anything else: from humidifiers, catheters, to extra connectors has to be ordered separately.

And that’s where in my opinion one of the downsides of Longevity’s services start: Longevity does not have an online shop. Every order is processed on the phone.

This can be a good thing or – not such a good thing.

It is a good thing if you’re new to home ozone applications, have no idea what you need to get started, which connectors go with which equipment and which regulator with which oxygen tank. In that case, the Longevity support staff will help you figure out what you need and put together a customized package for you.

On the other hand this could also be to your disadvantage, since after talking to the very persuasive sales staff you might find yourself buying equipment which you either might have bought at a much cheaper price elsewhere or which you don’t really need.

So the purchase of a $995 ozone generator can result in additional expenses of several hundred to a few thousand $.

If you have a large budget and don’t mind paying extra as long as you get everything you need from one source and do not need to shop around, then this is certainly the right place for you. You will get friendly, thorough phone support which will ensure that you get the highest quality products from a one-stop-shop: they have everything you need.

Longevity recently started uploading some pictures onto their website of the many accessories they sell. There is possibly also a full online shops in the works for the future, but as of now, one is still largely at the mercy of the sales staff.

The EXT50 110 V costs $995, the 240V version is available for $1,100.

It comes with a lifetime warranty on the quartz glass chamber and a 5 year warranty on electronics.

UPDATE! Until the 31st of October 2017 Longevity offers the following extras for visitors of thepowerofozone.com:
– 6 Feet of oxygen tubing
– 6 feet of Ozone Tubing
– 4 Pairs of Quick Connectors or Luer Connectors (your choice)
– Ozone Output Chart
– Two free ‘recalibrations’ service valued at $100 each

Make sure to let them know you have been referred by thepowerofozone.com!

 Did you call Longevity? If so, please let me know how it went at thepowerofozone@gmail.com. Thank you!

Summary: The EXT50 is an ozone classic: controlled entirely through the oxygen flow it is a simple no frills generator with an all-glass chamber. With the recent upgrade in ozone output from 55 to 65 mcg/ml makes it an even more attractive investment, suitable for any ozone application.

– bigger and heavier than other machines
– needs time to run at full ozone concentration
– some accessories are of low quality

The Canadian company Plasmafire Intl over the last 25 years has perfected Nikola Tesla’s cold plasma technology for ozone generators. It makes their products stand apart from all other ozone generators on the market which use corona discharge. The exact construction of the generators is kept secret by their designer Saul Pressman. What we do know is that it involves glass tubes with noble gases. It is a singular type of a dual dielectric ozone generator. The gases are excited by high voltage creating a plasma field through which oxygen flows. The oxygen picks up energy in the plasma field and some of it reassembles into ozone.

Other dual dielectric ozone generators also use glass as the dielectric material, but their electrodes are made of metal, usually stainless steel, aluminum or titanium. When metal is subjected to high current, considerable amounts of heat are generated. Cold plasma generators on the other hand are electrostatic devices which use voltage and do not create heat.

Consequently, they produce uncontaminated ozone and are extremely durable. Saul Pressman alleges that in the 23 years of production no uncontaminated Plasmafire tube has ever failed. The lack of any heat during the process makes them perfect devices to ozonate olive oil: they can be run continuously without any need for cooling.

Nikola Tesla, the inventor of the first cold plasma ozone generator

Nikola Tesla: his original electrostatic ozone invention lives on in the Plasmafire ozone generators.

Cold plasma generators also have a built-in safety precaution: they do not produce ozone concentrations above 70 mcg/ml. Interestingly, it has been determined that this is also the ozone concentration above which erythrocytes (red blood cells) are damaged by ozone. Which is the reason why high end German ozone generators (accessible only to medical professionals) do not exceed an ozone concentration of 70 mcg/ml.

There have been reports that the machines of another highly regarded ozone generator manufacturer were producing much higher ozone concentrations than quoted, of up to 40 mcg/ml more than supposed. So a setting which was supposed to produce 60 mcg/ml was measured to produce over 100 mcg/ml. Thanks to the neon tube technology, this could never happen with a Plasmafire generator.

There have been some rumors floating around that plasma generators are the only ones which are able to generate the right kind of ozone in order to combat Lyme disease. This is certainly not true. Ozone is ozone, doesn’t matter what type of technology is used. The quality of ozone is largely determined by the feed gas and internal parts of the generators.

With the Promolife Mini the Arkansas based company shows yet again what it’s best at: feeling the pulse of the ozone community and responding accordingly.

The Mini is an answer to the recent emergence of very affordable ozone generators. Unlike Promolife’s Mini, most other sellers give ambiguous and evasive answers about the provenance of their machines, just to avoid the “C” word, as in Made in China.

That is not the case with Promolife. Their generators are all Made in the USA.

The Mini allows to perform all home applications like ozonate water, various insufflations and even ozone saunas. Due to the fact that the ozone concentration is entirely regulated through the oxygen flow, this machine does offer less options.

For example: at the oxygen flow of 1/16 LPM the Mini produces only one ozone concentration, namely 52 mcg/ml.

The Promolife O3Elite Dual on the other side allows for 10 different concentrations at the flow of 1/16 LPM, ranging from 21 to 95 mcg/ml.

So when using the Mini one needs to increase the oxygen flow in order to achieve lower ozone concentrations. On other generators, one simply turns down the dial knob.

The maximum ozone output of the Mini is 65mcg/ml, which is likely more than what most people will need for most ozone applications. With ozone, more is not necessarily better. Most popular concentrations lie in the 20 to 40 mcg/ml range.

It is a mini machine with a maxi potential since the rich arsenal of Promolife’s online shop allows to pair it with any available accessory.

The Mini comes with Promolife’s trademark ceramic/stainless steel cell, a slick white metal casing with the output chart glued on top, additional silicone and vinyl tubing, dust caps for the luer ports, an array of power adapters, a manual, and a check valve.

– no dial knob, so limited variability in ozone output

I love to be positively surprised. And SimplyO3 has achieved just that. I wrote about this machine a year ago and I was not impressed. There were a few things I had not liked like the confusing chart, the too high ozone concentration at moderate oxygen flows and a discount model which applied only to wholesale buyers.

SimplyO3 heard me and they fixed all that! They even removed the sharp edges on the machine.

This cute little ozone generator now comes with a straightforward output chart printed on top. It has been modified so that it produces better ozone concentrations at low oxygen flows, and it offers attractive discounts for even single machine buyers.

Win-Win-Win.

I love it!

For such a simple machine, the Stratus 2.0 displays an astounding accuracy of its ozone output.

This is really a great machine for the small budget. For members of the Facebook group there is a discount available of $50. Join the group and you will receive a code which you can use at the check out. It applies to any purchase above $550.

The machine now produces adequate ozone concentrations at the most commonly used flows of 1/2 to 1/16 LPM. It is small and quiet. There is a built in fan which makes a pleasant, whizzing sound instead of a high pitched like some other ozone generators.

The clean, industrial look of the machine might seem familiar to you since other manufacturers have copied the casing. What makes this machine stand apart from other nearly equal looking products is the now modified ozone output which makes it more suitable for home ozone applications.

According to Micah Lowe, the founder of SimplyO3, the innards of the Stratus 2.0 consist of 100% ozone resistant materials like titanium, glass, silicone, and kynar.

The machine runs on any voltage in the world from 90 to 240 V. You just need the right plug adapter which is easily obtainable for a few bucks, and you can use the machine anywhere you want. The tiny size allows it to be easily transported.

The Stratus 2.0 does NOT have a dial, so the ozone concentration is adjusted solely through the oxygen flow.

The oxygen in port has a 3/16” outer diameter, the ozone out port is a luer lock. The machine comes with 6’ of silicone tubing which fits the oxygen in port perfectly, a luer lock connector for the ozone port, and a three year warranty.

There are discounts available: If you join the Facebook group “Ozone to Health” you will obtain an discount code for $50 off.

United Ozone is a new company founded by Brandon Smith who has earned his ozone chops while working for a present competitor of his.  

Brandon has been marketing his machine quite aggressively from the start.

Often, the more aggressive the competition, the better for the consumers.

This seems to be also true in this case. The biggest plus of United Ozone are the great packages the generators come with. For the price of $675 one can get an ozone machine and enough accessories to be able to do rectal, vaginal insufflations, and ozonate one’s water. Included is also a pediatric regulator, either for industrial or medical tanks.

The generator itself seems to be based on SimplyO3’s Stratus 2.0.

Yet, unlike their competitor, United Ozone claims that their generator is made in the USA.  

If this is true, then it seems that United Ozone was able to find internal parts and an adequate assembly line in the US in a very short amount of time AND at the same time is able to offer the machine for more than $100 less (when taking into account all the extras it comes with). How is this possible? Brandon says he simply refuses to sell his machine with the common “insane markups”.

The black case of The Ozone Box is yet another feature which makes this machine stand apart from the competition.

Just like the Longevity EXT50, the Promolife Mini or the SimplyO3 Stratus 2.0, the ozone concentration is solely regulated through the oxygen flow on either the oxygen tank or oxygen concentrator.

A big drawback that I see is that one of the ozone packages comes with supplements which contain chlorella, lipoic acid, methionine, and other potentially dangerous ingredients. All those supplements are known to mobilize and redistribute mercury, often leading to a worsening of mercury symptoms and possible permanent damage, as a growing collection of testimonials attests to.

Given that ozone can lead to highly uncomfortable Herxheimer reactions, people who might experience adverse symptoms from the supplements will have a hard time distinguishing one from the other.  Update October 2017: United Ozone does not sell supplements anymore.

The Ozone Box has a built-in destructor, comes with a lifetime warranty and a 60 days money back guarantee. It runs on universal voltage, anything from 100 to 240 V and comes with free shipping in the US.

[This review has been modified to accommodate complaints by Brandon about my original posting which I found justified.]

 

Summary: We have seen the basic concept of this machine before, here it comes with a slightly new look and a great package of accessories. Give the new guy a chance, but watch out for the supplements.

    Hi Paola,
    Im considering buying the Longevity ext 50.
    the part That confuses me is the 55ug/ml . Is that powerful enough to treat and help with Lyme etc?
    I don’t get what that refers to.

    Thank you so much ,
    Kim

      Hi Kim,
      55 ug/ml refers to the ozone concentration produced by the generators. ug is micrograms. So 55ug/ml means there are 55 micrograms of ozone per one milliliter of ozone/oxygen gas mix.
      The higher that number, the more powerful ozone output the machine produces.
      Many doctors who treat Lyme and other infections successfully, use ozone concentrations in the 40 to 50 ug/ml range, so yes it appears that is enough to help with Lyme. Successful ozone treatments also depend on the frequency and duration of applications, not only the concentration.
      Let me know if you have any other questions.
      Paola

    Hi I recently read on a blog that ozone can cause cancer because of oxidation in some people.. is that true or just a wives tale? I know one lyme patinet who claims she got cancer from ozone.

      Hi,
      there is lots of misinformation floating around about ozone.
      The way chemotherapy kills tumors is through oxidation. The same way radiation is used to shrink tumors: through oxidation. This is the same way ozone is used to combat cancer by many doctors worldwide. An oncologist in Spain actually is of the opinion that ozone therapy is much more effective in treating cancer than chemotherapy or radiation. So if someone says that oxidation caused their cancer, this is really really unlikely. What is more likely is that the ozone most likely postponed the emergence of the cancer.

    Hi,

    Some equipment mention quality certificate. Which quality certificate you refer, CE?

    Also, wouldn’t it be nice to plug all machines into a an analyzer to compare accuracy?

    Best O3 website ever, congrats Paola!

      Hi Eduardo,
      there are different certificates like CE, UL, or CSA. Those certificates mostly make sure that the machine won’t fry you when you plug it into the socket. It does not check for the purity of the ozone or if the ozone output is accurate or safe for therapeutic or any other administration.

      Yes, it would be fantastic to have such an analyzer. Just as it would be great to have a couple of grand to be able to buy them 🙂 … I think the cheapest Made in China analyzer runs at ca. $2,000 (plus customs fee). A better quality one at $4,000 to 5,000 …

      Hi Paola just asking but have you tried all generators in the list?

      I’m buying one of them; just ocurred to me is not the most popular one above.

    • paola d

      Hi Eduardo,
      no I have not tried them all.
      The ones I tried are: SimplyO3 Stratus, Promolife Dual Cell (since using just one cell is equivalent of using the single cell, I think I can also sat that I have a good idea how the Single cell works), I am in the process of trying out the Ozonette, I tried the EXT50, and I have been treated by doctors who used the old EXT120.
      Hope this helps.

    Hi Paola,
    I’ve spent all day today doing research on O3 machines. I’m very meticulous when it comes to gadgets of this order and my poor head is spinning by now!
    What a relief to have found your website! I now have my eyes on a Plasmafire Alpha V for later, when I can afford one. Meanwhile, you helped me to decide on a Longevity EXT50.
    Thank you very much for such an excellent, well researched post!

      Hi Pedro,
      thank you very much for reading my page!
      Enjoy your EXT50!

      Hi Paul,
      I am afraid the machine you linked to is not adequate for ozone saunas. It is not powerful enough and it also runs on ambient air. What you need is an ozone generator which runs on oxygen. Any of the machines presented here are good for ozone saunas http://thepowerofozone.com/equipment/ozone-generators/

    So the Ozone Box will work for a sauna? My Alpha V is not working & needs to be repaired or replaced. Any suggestions? Do you know where I can get it repaired since SP is not responding to emails? Perhaps I could sell at a reduced price to someone who knows how to repair Plasmafire products. I appreciate any help you can offer. Thanks

      Hi Jana,
      yes, the ozone box will work for a sauna.
      Which email address did you write to when trying to contact SP?

    • paola d

      Hi Jena,
      someone will contact you shortly about your Plasmafire, ok?

See, this will never happen here. I write waaay too slow to create spam. Just check out my blog. Even if I wanted to, I'm unable.
