Difference between buying ozone water and producing it on-site

What is the real difference between ‘buying ozone water’ and producing ozone water on-site with a dedicated system? This guide explains how ozone water works, why ready-made ozone water is not practical in daily operations and in which situations an on-site system is more cost effective than conventional chemicals.

Difference between buying ozone water and producing it on-site

Buying ozone water or producing it on-site?

 

Many organisations are interested in buying ozone water as an alternative to traditional cleaning chemicals. In practice, this almost never means ordering pallets with ready-made ozone water. Because ozone water has a half-life of roughly 15–30 minutes, its activity drops quickly after production. Our ozone water from the ozone water system is only intended for surface cleaning. It is not intended for consumption or medical applications.

 

What people really mean by ‘buying ozone water’

 

When people talk about buying ozone water, they usually mean one of two things:

  • investing in an ozone water system that produces ozone water on-site; or
  • working with a cleaning partner that uses ozone water at your facilities.

 

In both scenarios you are not buying a liquid with a long shelf life, but access to freshly produced ozone water that fits your daily cleaning routine.

 

Why ready-made ozone water is not practical

 

Ozone is an unstable form of oxygen. In water, ozone gradually falls back to normal oxygen, which reduces the active effect over time. Because this process happens relatively quickly, storing or transporting ozone water as a stock product is not very practical. By the time it is used, most of the activity may have disappeared.

That is why professional users prefer on-site generation. You can read more about the basics in our guide What is ozone water?.

 

Producing ozone water with a dedicated system

 

A modern ozone water system allows your staff to produce ozone water at the push of a button. Tap water is treated in a controlled way so that you obtain a consistent quality of cleaning water within safe limits for surface cleaning.

  • no heavy canisters or bottles to move around;
  • less storage space for hazardous chemicals;
  • a clear, repeatable cleaning procedure.

 

Why choose ozone water

 

✔️ Less chemistry: you reduce the use of conventional cleaning products and work with water that falls back to oxygen after use.

✔️ Less logistics: fewer pallets, fewer deliveries and fewer internal transport movements.

✔️ Using ozone water is cost saving: you lower your cost per litre of cleaning water and reduce spend on storage, handling and packaging waste.

 

Workflow: the two-cloth method

 

In daily practice, ozone water is used most effectively with the two-cloth method. One cloth is used to apply the ozone water and loosen soils, the second cloth is used to remove moisture and residues.

  • Cloth 1: dampen the cloth with fresh ozone water and wipe the surface so soils are loosened.
  • Cloth 2: use a dry or slightly damp cloth to pick up remaining moisture and residues.

 

A more detailed step-by-step description can be found in our guide two-cloth method.

 

Cost comparison: buying versus producing on-site

 

When comparing options, it is helpful to look beyond the price per bottle. An on-site ozone water system changes the way you organise cleaning: fewer deliveries, less storage and a more efficient workflow. The total cost picture is often more favourable than repeatedly buying and storing conventional chemicals.

 

Customer stories & experiences

 

  • “We first looked for a supplier of ozone water, but ultimately decided to invest in an on-site system. It fits our internal logistics much better.” (Facility manager, healthcare)
  • “Having fresh ozone water available on-site has reduced the number of products on our cleaning trolley and simplified our routines.” (Cleaning coordinator, office complex)

What is the difference between buying ozone water and producing it on-site?

Buying ozone water often refers to investing in an ozone water system or working with a partner that uses ozone water at your facilities. Because ozone water has a half-life of about 15–30 minutes, it is much more practical to produce it on-site and use it directly for surface cleaning.

Why is ready-made ozone water not practical as a stock product?

Ozone water has a relatively short half-life of roughly 15–30 minutes. Its activity decreases quickly after production, which makes long transport and storage impractical. That is why ozone water is usually produced on-site and used directly for surface cleaning.

Is ozone water safe to use?

An on-site ozone water system becomes interesting when you clean regularly and currently purchase and store significant volumes of traditional chemicals. You can save on products, logistics, storage and packaging waste, while simplifying your cleaning routines.

How can we start using ozone water in our organisation?

Start with a pilot area, choose which surfaces to clean with ozone water and train staff in the two-cloth method. Based on the results you can decide which type of ozone water system is the best fit for your locations.
