What is the purpose of a hot tub ozonator?

Hot tub ozone generators have an interesting way of keeping your hot tub clean. These devices inject ozone gas into your hot tub’s water, where that gas can remove contaminants like lotion and body oils. Once your ozone generator has captured these substances, they’re sent to a filter, where impurities are removed. An ozone generator can also help your hot tub filter run more effectively, so you don’t have to clean or replace it as frequently.

Do you need an ozone generator in a hot tub?

You don’t have to purchase an ozone generator for your hot tub, but these generators can be a great investment. Ozone generators can effectively remove lotions, oils, and other contaminants that most hot tub filters can’t capture. 

If you frequently notice a thin film of oil on the surface of your hot tub’s water, you may want to purchase an ozonator. Using a spa ozone generator can also help extend the life of your hot tub filter.

How much does a spa ozone generator cost?

A spa ozone generator for a hot tub isn’t as expensive as you may think. You can find a hot tub ozonator at Easy Spa Parts for under $100, but some of the models we carry cost $300 or more. 

That said, an ozonator is a wise investment when you consider how much money it could save you. Keeping your hot tub water clean and free of contaminants helps extend the life of your hot tub pump, filter, and other vital parts.

How do you maintain an ozonator for a hot tub?

If you want to ensure your hot tub ozone generator lasts as long as possible, it’s important to use the right spa chemicals. While you’d typically keep chlorine levels at about 1-3 PPM, you want to keep them at 0.5 PPM when using an ozonator. You should also maintain bromine levels at 1 PPM instead of the usual 3-5 PPM. 

If you take care of your ozonator and use the right hot tub chemicals, you can expect it to last approximately five years.

Are hot tub ozone generators safe?

Using an ozone generator for a hot tub is an effective way to remove oils and other residue that your hot tub filter can’t remove. The only byproduct of an ozone generator is ozone, which doesn’t pollute the air or affect your health. If you want to extend the life of your hot tub parts, using an ozone generator can be a great option.
