Ozone Filtration for your Electric Tub

At Tubby Tubs, we believe that stepping into your spa should feel like stepping into a silky cloud of peace, not a chlorinated soup with mystery floaties. That’s why every Tubby Tub is equipped with the SpaNet SV Mini 1 controller and its powerful little sidekick: an ozone filtration system. Sounds fancy, right? That’s because it is. But don’t worry—we’re here to break it down for you like your mate Dave explains craft beer (but with fewer beard references).

First Things First: What Even Is Ozone?

You’ve probably heard the word “ozone” tossed around in weather reports or by that one friend who wears toe shoes and talks about the “energy of water.” But in the spa world, ozone (O₃) is a superhero gas—basically oxygen’s overachieving cousin. It’s made up of three oxygen atoms, and that extra atom makes it incredibly reactive. And when it comes to cleaning water, reactive is exactly what we want.

So How Does This Magical Gas Clean My Tub?

The SpaNet SV Mini 1. This clever little controller doesn’t just manage your tub’s temperature—it also creates ozone on demand using a method called corona discharge. No, that’s not the name of a failed punk band from the ‘90s. It’s the process of splitting oxygen molecules to create ozone gas.

Once the ozone is made, it’s injected into your spa water through something called a venturi injector. (Sounds like sci-fi, but it’s just a smart little gadget that creates suction as water flows through it.) The ozone dissolves into the water, where it immediately starts hunting down bacteria, viruses, and any other uninvited guests trying to crash your soak session.

What’s So Great About Ozone Anyway?

Glad you asked! Here are a few reasons we love ozone more than we love cancelling plans:

1. It’s a Sanitising Beast

Ozone is about 50 times more powerful than chlorine when it comes to oxidizing contaminants—and it works about 3,000 times faster. Imagine a superhero speed-cleaning your spa water with laser beams. That’s ozone. It obliterates germs and any organic gunk like it’s got something to prove.

2. Less Chemical Soup

Because ozone does so much heavy lifting, you don’t need to use chlorine or bromine (at times you may need to "shock your water". That means less smell, less irritation to your eyes and skin, and less of that “I just bathed in a swimming pool” vibe. It’s also great news for people with sensitive skin or anyone who wants a more natural spa experience (so, basically all of us).

3. No Gross Byproducts

Unlike some chemical sanitisers that leave behind dodgy residues, ozone naturally reverts back to oxygen after it’s done cleaning. It’s like the James Bond of sanitisers—gets in, does the job, disappears without a trace.

4. Crystal Clear Water That Looks as Good as It Feels

Ozone breaks down organic materials that can cloud your water or give it that funky spa smell. The result? Water that’s sparkling clear and fresh-smelling—basically like soaking in a mountain spring, but without the mountain goats staring at you.

Why We Chose This for Your Tubby Tub

At Tubby Tubs, we design our spas for people who want maximum enjoyment with minimum fuss. The combination of the SpaNet SV Mini 1 controller and its ozone filtration system means:

• Fewer chemicals to manage

• Less time spent testing water

• More time soaking, sipping, and forgetting what day it is

It also means we’re doing our bit for the environment. Ozone is eco-friendly, doesn’t produce harmful byproducts, and reduces your reliance on synthetic chemicals. It’s better for you and better for the planet. Win-win.

In a (Bubble-Free) Nutshell

We use ozone filtration in our Tubby Tubs because it makes your water safer, clearer, and more enjoyable—with less chemical nonsense and more time to soak in pure, bubbly bliss. It’s like having a microscopic cleaning crew working 24/7 to keep your spa in top shape—without ever asking for a raise.
