Cost per litre of an ozone water machine for surface cleaning
This guide contains a complete blog series on ozone water machines. This article is one of the in-depth blogs within our guide and explains how to estimate the cost per litre of cleaning water from an ozone water machine or ozone water device. We make no odor, hygiene, food or medical claims; in this context ozone water is used strictly for surface cleaning and is not intended for consumption or medical use.
Why cost per litre matters
When you consider an ozone water machine or ozone water device, you want to understand more than the purchase price alone. The key question is what each litre of cleaning water costs in daily use. The strength of this technology lies in the fact that you produce water on site for surface cleaning, without storing bottles. As a result, costs shift: less packaging and logistics, more focus on the ozone water machine itself, energy use and maintenance.
Use ozone water only on closed surfaces such as tables, floors or tiles and always follow the safety instructions. The goal of this guide is to provide a sober, repeatable calculation model so you can estimate and compare cost per litre with your current solutions.
Which cost components are relevant?
To determine cost per litre of cleaning water from an ozone water machine you include three main categories: investment, operating cost and maintenance. This allows you to distribute the total cost of the ozone water device fairly over all litres produced during its lifetime.
- Investment: purchase price of the ozone water machine, including any installation work.
- Operating cost: water and electricity per litre of ozone water produced.
- Maintenance: periodic replacement of parts and any service visits.
You may add separate lines for staff time and training, but in many cases it is sufficient to start with these three components. The most important part is using the same method consistently so scenarios can be compared.
Step by step: from yearly volume to cost per litre
A practical approach is to first estimate your yearly volume in litres. How many litres of ozone water do you use on an average day, and on how many days per year is the ozone water machine in use? Multiply those values to find a yearly volume, then decide over how many years you want to depreciate the ozone water machine or ozone water device.
- Estimate daily use in litres of cleaning water.
- Multiply by the number of operating days per year.
- Choose a realistic depreciation period in years.
- Calculate total litres over the entire lifetime.
You then divide the purchase price by the total number of litres to find the investment component per litre. Next you add an estimated energy and water component per litre and include an allowance for maintenance. Together these elements create a clear picture of total cost per litre of cleaning water from your ozone water machine.
Example scenarios: smaller versus larger sites
Imagine a compact site where a single ozone water machine supports cleaning several rooms each day. You might use around 80 litres per day, 250 days per year. Over a five-year period this adds up to hundreds of thousands of litres. A mid-sized ozone water device with simple controls can deliver a very low cost per litre in this scenario because the investment is spread over many cleaning cycles.
At larger sites, such as facilities management or retail chains, daily use may be much higher. In that case it is worth calculating multiple scenarios: one central ozone water machine or several smaller ozone water devices closer to the work areas. The formula for cost per litre stays the same, but the outcome shifts due to different volumes and maintenance intervals.
Costs and affordability
At roughly a fraction of a cent per litre you can produce your own cleaning water from the tap with an ozone water machine, without depending on bottled stock.
✔️ You mainly pay for the ozone water device, not for packaging and transport.
✔️ Operating cost per litre remains low thanks to modest energy and water use.
✔️ You can easily recalculate costs whenever your usage pattern changes.
✔️ A stable workflow helps you avoid waste and keep consumption under control.
Over time you plan maintenance, for example a set of parts after a certain number of run hours or litres produced. This keeps performance stable and reduces the risk of downtime.
