If you ever wondered how do hot tub ozonators work and all you know is that it helps you sanitize your hot tub, you are in luck, because I can explain. A hot tub ozonator allows you to control the quality of your water and it will save you plenty of money too.
Ozonators split oxygen molecules into two free oxygen atoms in one of two ways:
- Intense ultraviolet (UV) light or by using what’s known as a corona discharge (CD) unit
- Or it will convert oxygen into ozone by pulling air across an ultraviolet bulb or corona.
When these freed oxygen atoms combine with existing oxygen molecules present in the water, they create ozone.
How To Install An Ozonator?
Install The Check Valve
Your ozonator requires a check valve that will help stop the backflow of the hot tub water into the device. This could possibly destroy the ozonator. Usually, the valve is built-in, but sometimes, it may have to be installed separately.
In case you decide to install it separately, cut through the tube leading to the jet tubing, insert the valve and then secure it in place using the clamps.
Check The Wiring
Ozonators are usually wired for 110 or 220 volt systems. You should refer to your user manual for the large part as this step may differ from unit to unit. If you are not familiar with this step, hire a professional electrician to finish the rest of the installation.
Set the Timer
In case your new ozonator does not come with a timer, take some time to install it yourself. Ozonator must run for at least three hours for every 12 hours. The longer the ozonator runs, the more effective it will be in cleansing your hot tub water. If the pump you are using does not filter, ozone will not be introduced into the water system.

How Long Do Hot Tub Ozonators Last?
Ozone gas will only remain present for about 12 hours, once injected into the hot tub water. This means that at the end of it, your hot tub wont have any sanitizer left in it. That’s why it is suggested that an ozonator be turned on at least 2 hours over the course of12 hours. This action will ensure that there is the right amount of ozone sanitizer in the hot tub water at all times.
You have to know that the ozone is a strong oxidizer, but since it doesn’t last long it needs to be constantly refreshed by the ozone generator. It needs to run at least 4-6 hours per day to continuously dissolve contaminants in the hot tub water.
Do You Need Ozone In A Hot Tub?
Most of the latest hot tub models already come installed with an ozonator. It is a great replacement to your chlorine, and it offers a significant reduction of chemicals used in the long term.
The ozone technology helps kill pathogenic bacteria, germs, and viruses. That means you can use less sanitizer, cutting your hot tub expenses while making your hot tuba happier place for people with chemical sensitivities.
What Does Ozone Do in Hot Tubs ?
There are a few things that ozone is really good at.
- Reduces a need for high chemical doses like chlorine or bromine.
Ozone, in fact, is a great hot tub oxidizer, sanitizer, and it is a safer alternative to chlorine. It destroys and kills bacteria continuously. Ozone does almost everything chlorine does except that it does way better.
- Helps destroy bacteria, viruses, algae, and yeasts.
Using ozone reduces the need for high chemical doses because it helps in destroying bacteria, viruses, algae, and yeasts and oxidizes other contaminants. Most importantly, ozone reduces odor and prolongs the life of your hot tub equipment.
- Oxidizes other contaminants.
Once a system has delivered ozone, it cleans the target water or produces ozone-enriched water to sanitize a surface through ozone oxidation. The unstable third oxygen is combined with organic and inorganic molecules which destroys them through the process of oxidation.
- Less odor and chloramines.
Ozone is a more effective disinfectant than chlorine, chlorinates, and even chlorine dioxide. This will lead to a more complete disinfection and a lower disinfectant concentration that will eliminate Odor and taste in the water.
- Prolongs the life of the hot tub equipment
It can help to expand the life of your other hot tub equipment because it significantly reduces the maintenance time and costs, all while purifying your hot tub water naturally. Ozone reduces the need for regular shock treatments because ozone serves as an automatic, daily, non-chlorine shock.
- Reduces maintenance time and cost.
Ozone will reduce the need for high levels of harsh chemicals like chlorine and bromine. Purposely reducing maintenance costs on chemicals, filters, pillows, and covers. Ozone helps in the removal of minerals such as iron and manganese. Ozone leaves no unpleasant chemical taste and is less corrosive than chlorine and other harsh chemicals in the water.
- Gives natural purification.
Ozone is an outstanding disinfectant with the superior ability to kill viruses and biological contaminants found in the water. It is also the most powerful oxidant that can oxidize metals in water such as manganese, iron, and sulfur into small particles, aiding in their filtration and removal from the hot tub water.
- Ozone could also oxidize soap, deodorant, hair spray, cologne, makeup, perfume, body lotion, hand cream, suntan lotion, saliva, and urine. If it is used in combination with your sanitizer, ozone helps kill pathogenic bacteria, germs, and viruses and helps to oxidize organic contaminants.
- Ozone frees up combined chlorine and bromine. Freeing them to be continuously reused. Ozone can help in enhancing the performance of chlorine and bromine as well as alternative sanitizer systems.
- Less chlorine or bromine is sometimes needed to maintain a residual. Water quality will be better with the combination of ozone and chlorine/bromine than with chlorine/bromine alone.
- Ozone destroys microbes, oxidizes contaminants, and causes total dissolved solids to clump together for easier removal by the filter as a result, water becomes cleaner and provides a smoother feeling to the skin.
What Does The Ozonator Do On A Hot Tub?
Ozone is known in breaking down body oils that help to remove chronic odors often found in hot tubs. Ozonated water doesn’t need to be repeatedly changed, as it remains fresh for a long time. Compared with commercial hot tub chemicals, ozone does not have an obvious taste or color. Ozone doesn’t leave any residues in your hot tub that could stick to the surface of the hot tub or could cause a cloth in the hot tub filter. Ozonator-treated hot tub water doesn’t need to be changed for about 7 to 9 months.
Ozonator is a powerful oxidizer of contaminants in water. It can be installed on hot tubs and spas by the use of ozone generators. Ozone is formed when three atoms of oxygen are bound together. If you have ever noticed a faint, sweet smell in the air after a lightning storm, that was ozone!
Ozonator works during the filtration cycle. The ozonator doesn’t create bubbles. One end of the ozonator has an open port that serves as a source for air. It’s basically just a hole inside the case. The ozonator is attached by plastic tubing to an ozone injector, which is a fitting in the circulation line that sucks the air in that plastic tube into the water that’s being circulated.
Ozone kills microbes and keeps your water clean. Signs of a non-functioning ozonator is when water suddenly becomes dirty, even though your disinfection cycle hasn’t changed. Sometimes, it’s because one-way valve sticks open and water gets sucked back into the ozonator. That usually causes the hot tub to short out, although that’s not always the case.
