How It Works

The Aero-Spa™ system is a high output ozone generator that is five times more powerful than a built-in ozone generator. Because of the high output it becomes the primary sanitizer of the water. The Aero-Spa™ system can be installed in minutes without tools.

The Aero-Spa™ Difference

If you have a hot tub, you are very familiar with the issues related to the use of chemicals to sanitize your hot tub. The chemicals such as chlorine, bromine, pH up, pH down, shock (hydrochloric acid), clarifier and de-foamers are all used to sanitize and clarify the water. This concoction of hazardous materials produces vapors and substances that cause respiratory irritation, skin rashes, discoloration of clothing and environmental issues.
These chemicals need to be added continuously to be effective. After a short period of time the water becomes saturated and the chemicals are no longer effective or the chemistry becomes so unstable that it is impossible to balance to the required levels.
When the water becomes chemically saturated the water must be changed. All of the chemical laden water is typically discharged to the environment with complete disregard for its effect. In addition to the environmental issues, the hot tub must be refilled. Depending on the water source used for refill, the balancing act must begin again to adjust for hardness and iron content. Additionally, a significant amount of energy is consumed in pumping the water and heating the water from somewhere around 50º to 100º + degrees.

Using the Aero-Spa™ system will provide an enjoyable hot tub experience without the work and side effects of harsh chemicals.

Keep your water as clear as nature provided it to us!

5-Minute Installation Process


Set & Connect

Place the Aero-Spa™ enclosure within 20′ of Hot tub in an area that is not prone to flooding. Connect the ozone tube to the check valve.


Install Diffuser

Gently lower the diffuser into the Hot tub while routing the ozone tube over the sidewall of the Hot tub at the center adjacent to the cover hinge.


Finish Up

Plug the timer into the nearest GFCI protected 120 volt outlet. Plug the Aero-Spa™ into the timer and set the timer to the current time of day. Enjoy!

What is a virtually chemical free pool / hot tub?

Our customers have been using the Aero-Spa™ system as the primary water treatment process for years with limited & reduced use of harsh chemicals. Because we cannot control how your hot tub is used/maintained, the EPA requires we recommend maintaining at least 1 PPM minimum of an approved residual sanitizer to minimize cross contamination of users. Water care and sanitizing is the sole responsibility of the owner. To put this into perspective, the EPA recommends 4 PPM residual chlorine in public drinking water, so the concentration of chlorine will be 4x less than the water you drink or bathe in. To obtain a 1 PPM ratio in a 500 gallon hot tub, you would need to add about 0.63 OZ (1.25 tablespoons) of regular household bleach (6% sodium hypochlorite). If you substitute swimming pool chlorine (10% – 15% sodium hypochlorite) you would need about half as much.

In a hot tub without ozone, much of the chlorine reacts with compounds such as body oil, perspiration, etc to form chloramines. Chloramines have no sanitizing ability and produce the harsh “chlorine” smell. Because of the superior oxidizing ability of ozone, these compounds are quickly reduced and filtered out. This keeps the chlorine free to work as a sanitizer if needed in adverse conditions.

How does Aero-Spa™ achieve a virtually chemical free pool / hot tub?

At the heart of the Aero-Spa™ system is a high output corona discharge ozone generator. The Aero-Spa™ ozone system produces 5 X the amount of ozone that built-in ozone generators produce. Because built-in ozone generators have no direct user controls the UL/ANSI standard sets off-gassing limits. Therefore, they must limit the ozone output. The Spa / Hot Tub manufacturers cannot obtain a virtually chemical free spa / hot tub. The Aero-Spa™ ozone system has user interface controls so the ozone generator can be shut off while the Spa / Hot Tub is in use.

Ozone 101

Ozone was discovered in the 1800’s. It is commonly referred to as active oxygen or trioxygen. It is one of the most powerful oxidants known and is several thousand times faster than chlorine. Ozone cannot be stored. Therefore, it must be manufactured on site using special equipment. The molecular symbol is O3.
The equipment used to generate ozone is called a corona discharge cell. This device creates a high voltage arc within the cell. As air passes through the cell it splits the O2 molecules into two O atoms. These free O atoms attach to unsplit O2 molecules forming O3 (ozone). The third O atom has a loose bond and is therefore very unstable. When the ozone comes in contact with organic material e.g. bacteria, body oil, soaps, etc., it gives up the third atom to oxidize these organic materials. After the reaction (release of the O atom), the ozone reverts back to O2.
