Should ozonators be used on indoor hot tubs?

When it comes to hot tub (and pool) water maintenance there are many choices, some better than others. Here at Almost Heaven we believe that using a metallic ionizer is far superior to ozone and halogen sanitizers (chlorine and bromine), especially when a hot tub or pool is installed indoors where the fumes from ozone and halogens can quickly create an unsafe environment.

We haven’t heard many people disputing the dangers of chlorine and bromine, especially in a gaseous form, but the same can not be said of ozone. Many people believe ozone is perfectly safe, despite a plethora of information to the contrary.

It’s a well known fact that high levels of ozone in the air are dangerous. The EPA’s National Ambient Air Quality Standard for ozone is a maximum 8 hour average outdoor concentration of 0.08 ppm. You can see this on their own website at…

The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm for 8 hours. You can see this in a CDC document published here…

At the following link, which is about using Ozone as an air cleaner, the EPA states “…ozone is an irritant gas that reacts with lung tissue and can cause asthma attacks; coughing; chest discomfort; irritation of the nose, throat, and trachea; and other adverse health effects. As ozone reacts with chemical pollutants, it can produce harmful by-products.”

Now with all that said, what do you think happens when a hot tub is placed indoors, in an enclosed area? The fumes from the ozone used would gather in the enclosed space. How would you measure the exact ppm of ozone to ensure it wasn’t exceeding the standards set by OSHA and the EPA? Is it any wonder that there have been rumors of banning ozone used on indoor tubs and pools?

Do your own research and we’re sure you’ll come to the same conclusion. Using ozone on an indoor hot tub or pool can be very dangerous for the respiratory health of yourself and those you love.

    YES ozone in air is bad to breathe. But, when injected into the WATER, ozone is harmless to people and kills 99.99% of all viruses and bacteria in the water. It’s when people don’t have a proper method of injection that the ozone off gassing. Does anyone ever stop and think about the chemical fumes they breathe…especially in indoor applications? So, yes I agree with you, but there’s another layer of truth to it that most don’t understand.

    Jennifer, we’ve had plenty of customers with asthma (or with children who have respiratory sensitivity) who were unable to use a hot tub with an ozonator, indoors or out. If there’s a way to eliminate the need for ozone AND chemical halogens, why wouldn’t you?
