Ozone Water vs Pure (RO/DI) Water: What’s the Difference?
Choose the right water for the job: ozone water for degreasing and freshness; pure (RO/DI) water for streak-free glass.
A practical comparison of ozone water vs pure/DI water for cleaning—focus on efficiency, cost and sustainability (no biocidal claims).
Ozone water vs pure water: make the right choice
Two waters, two purposes
Ozone water helps remove light soils and oils without residues. Pure (RO/DI) water dries spot-free—perfect for glass.
Where each shines
- Ozone: kitchens, bathrooms, floors, odour-prone areas.
- RO/DI: windows, mirrors, stainless, high-gloss finishing.
Costs & sustainability
- Ozone: fewer chemicals, less plastic, faster workflows.
- RO/DI: less wiping/polishing, consider filter maintenance and reject water.
Workflow tip
Pre-clean with ozone water, finish with RO/DI for streak-free glass. Learn more: degreaser, cost savings. Generate on site: machine.
Further reading
What is RO/DI water?
Reverse-osmosis/deionized water with very low mineral content.
Does ozone water leave residues?
No, when used correctly it evaporates cleanly and leaves no film.
Which is better for glass?
Degreasing, freshness, and fast daily cleaning.
Is combining both useful?
Often yes: ozone for pre-clean, RO/DI for the final finish.
