Say hello to Scarecrow, your cutting-edge commercial air purifying unit, new to Purozo. Find out more.

The powerful
Tersano Lotus® Pro cleaning system

Whilst Aqueous Ozone has been used as a powerful cleaner and sanitiser for over a hundred years, the Tersano Lotus® Pro is the first and only product to stabilise the Aqueous Ozone, so that it lasts for up to 24 hours as an effective cleaner and sanitiser.

Approved by many of the leading governing bodies across the world, Stabilised Aqueous Ozone provides a simple, safe and sustainable alternative to traditional cleaning chemicals. Currently used around the world and in various industries, we supply, install and maintain Lotus® Pro systems for our customers all across the UK.

How the Lotus® Pro works

A permanent fixture that is connected to your power & water supply

The Lotus® Pro is a permanent fixture that is mounted onto the wall and connected to your power and water supply, enabling you to create Stabilised Aqueous Ozone whenever you need.

Stabilised Aqueous Ozone is created at the push of a button

At the push of a button, cold water is automatically added to the stabilisation module compartment, which changes the mineral composition of the water. It is this process that allows the aqueous ozone to stay stabilised for longer. The water is then passed through to the main Lotus® Pro unit, where Oxygen and volts of electricity is added, converting O2 into O3. This creates Stabilised Aqueous Ozone.

A highly effective cleaner and sanitiser for up to 24 hours

The unit then dispenses the Stabilised Aqueous Ozone into mop buckets, floor scrubbers or spray bottles, providing you with a powerful sanitiser and cleaner for 4 or 24 hours, depending on your cartridge type. It is whilst in this stabilised form that the composition becomes highly effective, clinging to dirt, grime and bacteria, killing up to 99.999% of harmful contaminants. Once the 4 or 24 hours are up, it simply reverts to normal tap water, and you can pour it away without any harm at all to the environment.

How you use it

The Lotus® Pro SAO™ dispenser is simple to use and allows you to clean entire buildings using just one batch. No more storing, mixing, or disposing of traditional chemicals, you can create Stabilised Aqueous Ozone at the push of a button.

Switch on

Turn on the cold water source and push the 'on' button on the unit. Wait until 'System ready' green light is showing.

Fill up

You can now fill up spray bottles, buckets and floor scrubbers with SAO™ dispensed from the unit.


The SAO™ can be used for cleaning and sanitisation for up to 24 hours*, after which it returns to normal water and can be safely poured away.

Ongoing maintenance and support

Installation by our expert team

Once you’ve purchased the Lotus® Pro unit, our team of experts will install it for you so that it is set up and ready to use straight away. We can also provide a demonstration of how it works to key staff members.

Ongoing support with regular visits

Like most technology, the Lotus® Pro system requires maintaining to ensure it stays in working order. Every quarter, we offer a free service to our customers and will send out one of our expert engineers to check the unit over and ensure it is working efficiently.

Ongoing assistance with cartridge replacements

Providing the unit is regularly maintained, the only part that will need replacing is the cartridge. The cartridge can last a number of months before needing to be replaced – even when used daily – making it highly cost-efficient.

Make considerable cost savings

Aside from killing up 99.999% of bacteria, switching to SAO™ eliminates the need to purchase multiple products. As a reusable product, it only requires a replacement cartridge (costing £300) every few months.
