O3 Waterworks Review: Cleaning With Ozone, Not Chemicals
The verdict
O3 Waterworks turns ordinary tap water into an ozone-based cleaner and sanitiser, so there are no detergents or chemicals to buy, store or breathe in. The Smart Laundry System and spray bottle have had genuine mainstream press coverage. If your goal is to cut chemical cleaners around the house, it's a clever, genuinely different product, just understand it's best for everyday sanitising rather than every heavy-duty job.

Most cleaning means buying bottle after bottle of chemical spray, storing them, and breathing in the fumes. Ozone offers a different route: it's a powerful natural oxidiser that sanitises and then reverts back to ordinary oxygen, leaving no chemical residue.
O3 Waterworks puts that into a consumer device. You fill it with tap water, it ozonates the water on demand, and you clean and sanitise with that, no detergents required. The Smart Laundry System extends the same idea to washing, and the brand has had coverage in outlets like Forbes and Fast Company. It's one of the more genuinely novel products in this whole line-up.

Realistic expectations: ozone is excellent for everyday sanitising and odours, but it isn't a magic stain remover, some heavy jobs still need a dedicated product.
