What can be the reactions to ozone if you might be allergic to it?
Anyone had any kind of reaction to it?
-
I guess I would qualify - though I have never had an allergy test done by a doctor.
For me, it causes my chest to constrict as if I was having an attack of asthma. I do have asthma, but I haven't had any trouble with it in years.
The only time this happens for me is when I walk into a room with one of those 'Classic Air Purifiers' or a similar product which pumps large amounts of ozone into a room. No spa that I have ever sat in has causes a reaction, even in the showroom. The irony is, the Pastor of our church has a strong reaction to mold, so he keeps one or two of these machines running around him at the church. They even put one in the air return of the heating system for a couple of weeks, and I was miserable.

is your spa inside or outside?
-
I'm a dealer and I have several running in the showroom, only one of them has ozone.
I have had ozone on my spa outdoors - though not recently.
None of the spas have ever bothered me with ozone-related problems, even back when we had a more closed-in 'mood room.'
-
There was a health warning a few years ago about "indoor air cleaners" and the amount of ozone they produce. Apparently some of them produced harmful amounts of ozone.
Also, like anything else - some people are more susceptible to certain things than others - look at the posts where a family gets into a hot tub and 1 person breaks out in a rash!
-
at Hot water class I recently attented.....they made mention of a small dog being the equal of putting 50 people in your spa..not a good idea.....
-
which people?
;)
-
Did you ever figure out what was causing your reaction to ozone in your hot tub? I have the same reaction and it seems to only affect me. The rash started after we added the Ozone.

Did anything else change in your chemical routine when you switched to ozone?

Ozone in hot tubs shuts off when any of the buttons are touched. It will not come back on for at least 40 minutes after the last button was touched. It is a safty feature because ozone is a poisonous gas, and it can burn your skin if you hold your body next to the jet it is coming out of. Ozone also should not be run in indoor tubs unless you have proper ventilation. After it shuts off, it dissipates very quickly, no risdual is left in the water.
What kind of reation are you having and when?
I have the same reaction as Chas, It sets off my Asthma, but only if I open my cover just a little bit and stcik my head in to check water chemistry ect. I have learned to hit one of the jets on for a minutes to shut the ozone off before I do this now.
I just got back from Florida where we visited Busch Gardens. They treat all the little brooks and water features around the park with ozone. It was very powerful and at times caused a chest tightening issue with me. I was surprised they pumped that much ozone into the water, but I guess they have to will all the birds and such.

Someone has grossly misinformed you about ozone. I'm not aware of any hot that shuts off ozone as a safety feature. HotSpring certainly does not. It runs 24/7. The amount of ozone produced by a hot tub is far, far below harmful levels. It will not burn your skin in a hot tub. It is perfectly safe, and recommended, to leave the ozone running on an indoor hot tub (not that you could turn it off without making potentially warranty-voiding modifications, anyway). Any amount of recommended ventilation would be to prevent high levels of humidity - not ozone.
In fact, the amount of ozone that hot tubs produce is so small to begin with that it must be used with other chemicals to be remotely effective. It won't do much all by itself, but it's certainly not harmful in hot tub applications by any means. I just don't want people to get scared and start ripping out their ozone generators and putting themselves at risk for electrocution. :)

You too ;D ;D More recently made spas, in order to meet UL guidelines must have the ozone OFF while the spa is being used.
Ozone, even the small amount produced in a spa, CAN be VERY harmful to some people. MANY people have respiratory sensitivities to ozone. Especially those with asthma (including those that NEVER knew they had it, till they came in contact with the high levels of ozone a spa CAN produce)
Ozone in water has a VERY short half life, generally seconds to minutes. In air, the half life goes to HOURS. Ozone is heavier than air and will tend to settle in low areas and can accumulate to quite high levels. I've seen $20k plasmas TVs and other electronics DESTROYED by ozone (ozone works quite well at deteriorating some plastics used in electronics...as well as plastic wire insulation).
-
Sorry guys. Different strokes for different folks. Some spas have the ozone turn off, others do not.
-
I feel the need to clarify - I have never had a reaction to ozone from a spa. I mentioned that it triggers my asthma when in the presence of an AIR freshening unit, or units.

I work around two or three tubs running with ozone systems at work all day. No reaction. The HotSpring spas on our floor come with factory-installed O3 systems, but I have not added it to the Tiger River or Limelight spas which I also have running.
I will, someday, because the HS are far easier to keep clean and clear on the showroom floor.

If it does not turn off, it is not UL listed. Older spas may have ozone that does not shut off, but the newer spas should not....I can not speak for the ones make in China ect though....God only knows.
I agree with Dr.Spa 100% on this, he has everything exactly as I have learned it.
It is not a huge thing if you have an indoor tub just to unplug the ozone from the control system, no ripping wires out.

If this is true, then either my 2008 Sovereign is "older", broken, or made in China because the ozone generator continues to produce ozone anytime the circulation pump is on, which is...always.
-
"bubbles" can still be introduced into the water, but by no means does this mean that it's creating ozone.
As air passes through the ozonator, some of the oxygen is converted to ozone (if the ozonator is on and working). If the ozonator ISN'T on, air is passing through the ozonator.

I understand the difference between bubbles and ozone. That's why I said ozone. I know what ozone smells like. Constant voltage to the ozone generator from the IQ2020 control panel is a pretty good sign, too. :D The only time my ozone goes off is if the circulation pump stops. Two things cause the circulation to stop: First, if the high limit thermistor indicates excess temperature caused by a bad pump, faulty temperature control, stuck relay, clogged line, loss of prime, etc. Second, if a low/no flow condition is detected by the pressure switch due to a bad pump, clogged line, or loss or prime.

Or a dirty filter.

True, true! I'll roll "dirty filter" into the "low flow condition caused by a clogged..." situation. :D

OZONE:
An unstable, poisonous allotrope of oxygen, O3, that is formed naturally in the ozone layer from atmospheric oxygen by electric discharge or exposure to ultraviolet radiation, also produced in the lower atmosphere by the photochemical reaction of certain pollutants. It is a highly reactive oxidizing agent used to deodorize air, purify water, and treat industrial wastes.
Ozone has a characteristic, pungent odor familiar to most persons because ozone is formed when electrical apparatus produces sparks in air. Ozone is irritating to mucous membranes and toxic to human beings and lower animals.
Ozone is a gas containing three atoms of oxygen per molecule. It occurs naturally at about 0.01 parts per million (ppm), but the concentration can be increased by the photochemical action of sunlight on the products of the combustion of fossil fuels. At concentrations greater than 0.1 ppm, ozone is toxic and can be a potent bronchial irritant, making breathing difficult.
I don't think I want my ozone running while I am in the tub. I really hope Hot Springs has ozone supression in the tub for saftey.

Yeah. Too much of a lot of things aren't good for you, but in moderation they aren't harmful (and sometimes even beneficial). Alcohol comes to mind. Studies show a little bit is good is good for your heart, but too much kills your liver. A couple of Tylenol are great for a headache or fever, but if you take the whole bottle you're going to get pretty sick. Your body needs a little bit of salt to survive, but too much will kill you. Another great example is sanitizer, such as dichlor. It's poisonous. Try sprinkling a tablespoon on your salad - you're gonna get sick. On the other hand, if you don't use any then you're probably going to end up with a nasty infection. See the pattern developing here?
-
I was under the impression that passing UL had to due with measurement of how much off gassing there is. Maybe some have to turn them off at times because of the off gassing and other don't!?

Aren't studies amazing? The newest study shows that alcohol, even in small amounts, such as 2 drinks a week, increases a woman's chances of getting cancer.

I bet studies would show that 6 drinks at a bar increases a woman's chances of getting pregnant :P

Some spas have O3 on 24/7, others it shut off when a button is pushed (would indicate to the system that the spa is in use).
Something very important is that you say you had ozone "fitted"? If you mean retro-fitted and it wasnt fitted correctly, this could be the cause.
Ozone takes a long time to dissolve into the water. Hence why many brands advertise a "mixing chamber" basically a coil, loop or wiggle of pipe which sits between the mazzei injector and the jet inside the spa.
This gives the ozone time to properly dissolve into the water, rather than having loads of O3 bubbles bursting on the surface - two VERY different setups.
Incidentally some brands are developing systems that vent the "off gas" away from the spa so that you dont cop a lung full when you remove the cover.
The Spa Net XS3000 control system (Australian Company) features a hidden menu fucntion accessed by holding doen a button combo. This enalbes "O3 off" and "O3 on" - Off = will turn off the o3 when a button is pressed, On = Ozone on whenever the circ is on.
One technology that I'm only aware of in one brand at the mo is UV disinfection. Now believe me when I say this COMPLETELY DIFFERENT to a UV Ozone Generator! UV disinfection doesnt create any Ozone gas, but plugs into the "Ozone" AMP socket - hence why Spa Net offer the hidden override...
A UV Sanitiser is a stainless steel tube, with a glass tube running down the centre. A UV bulb is inserted into the glass tube an emits UV light which penetrates the water and destroys bacteria, yeasts, moulds and viruses. The stainless steel tube has a flow/return line which comes from the Circ pump line.
My spa at home has this, and its sooooo much easier to look after. Ph, TA and Br levels seem to fluctuate much less than with my previous spa (which admittedly didnt have ozone either).
UV saniteisers are common in Council Swimming Baths, Spring Water Bottling, and fish ponds (the latter of the two would not tolerate Ozone).
There is a lot of reserach to demonstrate that breathing Ozone gas is bad for you, particularly if you have Athsma.
This seems to be a groundbreaking area in the industry at the moment, so any comments or information on this topic would be appreicated - knowlege is power! :)
