Designed and engineered to pump your hot tub full of ozone gas, these amazing little pieces of technology (when installed properly and used correctly) cut out a lot of the maintenance you need to do to keep your hot tub crystal-clear and perfectly healthy.

Of course, finding the best hot tub Ozonator is nowhere near as simple or as straightforward a process as you might think it to be.

No, it’s not that there are so few great options out there to pick and choose from – but that there are so many!

Trying to zero in on just one hot tub Ozonator for your set up can be a bit of a tall task. But that’s why we have put together this quick guide. By the time you’re done with the inside info below, you’ll know exactly what it takes to get your hands on the best hot tub Ozonator on the market today.

Let’s dig right in!

What Do Ozonators Do, Really?

The name “ozonator” sounds pretty high-tech and pretty fancy, but in reality, the technology is pretty simple and straightforward and designed to do one thing and one thing only – generate and flood your hot tub water with ozone gas.

This specific approach helps to eliminate impurities from your hot tub water almost immediately upon contact, but it also cuts down on the number of chemicals you would have otherwise had to pump into your spa.

With ozone, you’re able to get crystal-clear water that doesn’t have to be super chlorinated or shocked with chemicals all the time, and you also get healthier and cleaner water that doesn’t just look fantastic but is a lot safer to enjoy as well.

Ozonator technology is particularly useful for folks that want to spend more time enjoying their hot tub and less time cleaning it. It automates a lot of the maintenance completely all by using ozone gas to handle the heavy lifting of killing off bacteria and other contaminants.

This is not to suggest that Ozonator technology alone is going to be enough to keep your hot tub perfectly clean and super healthy.

You’ll still want to use a hot tub sanitizer every now and again (chlorine and bromide work wonders), but when used in conjunction with those chemical compounds ozone is going to devastate bacteria, crush germs, and kill off viruses that would have otherwise festered beneath the surface of your hot tub water.

On top of that, ozone gas breaks down other harmful chemicals and causes dissolved solids to clump together so that your filtration system can clean out your spa a lot easier. You’ll feel a lot fresher every time you get into and out of your hot tub when an Ozonator has been installed, that’s for sure.

What to Look for in a Hot Tub Ozonator

Before we cover our four favorite Ozonator solutions we thought we might touch on a couple of key things you want to look for in this new technology.

Ultraviolet Light Ozonators

Ultraviolet light Ozonator solutions are incredibly powerful, reliable, and the Ozonator technology that has been tested the most because it’s been around longer.

Taking advantage of ultraviolet light to split oxygen molecules, creating free oxygen atoms along the way that combined with ambient oxygen to generate new ozone automatically, these units have slightly lower shelf lives than Corona Discharge Ozonator options (something we highlighted a moment) but are still rock solid and dependable.

One of the biggest advantages of UV Ozonator is that they specifically aren’t negatively impacted by ambient humidity levels. You’ll be able to pump out ozone gas consistently in the middle of summer down in swampy Florida just as you would in the middle of winter in dry and arid Colorado – all without any headache or hassle whatsoever.

Corona Discharge Ozonators

Corona discharge Ozonator, on the other hand, takes advantage of more modern technology than UV light options. Using a sheet of plasma created by an ionized conductor, hot tub owners love how efficiently these units work as well as how long-lasting they are – not to mention the fact that Corona discharge options can tackle a lot more hot tub water than UV ones can.

Best of all, Corona discharge options do not require cartridges, chips, or lightbulbs that need to be replaced the way that UV options will. It’s possible for a Corona discharge Ozonator to last a decade or longer before a plasma sheet needs to be replaced.

On the flip side of things, Corona discharge options do not have the same kind of resistance to ambient humidity that ultraviolet options will. If you live in areas with relatively high humidity (60% humidity or higher) you’ll want to go with UV technology for sure.
