About O3 Waterworks

Editorially researched & verified

O3 Waterworks is a direct-to-consumer brand selling ozone-powered home cleaning devices through its website at o3waterworks.com. The company's flagship product line centers on the Smart Laundry System, a device that infuses tap water with ozone (O3) to clean laundry without traditional detergent. The technology is positioned as an eco-friendly, cost-saving alternative backed by the same aqueous ozone science used in hospitals and major hotel chains for decades.

The current product lineup includes the Smart Laundry System (Signature Model LM201) at $319, which operates automatically with a set-and-forget design, and the Smart Laundry System +PLUS (LM301) at $499, which adds a wireless remote control with three modes: Normal Mode (0.5ppm O3), Boost Mode (1.0ppm O3), and a water-only No O3 Mode. The Pro Spray Bottle at $499 extends ozone cleaning to household surfaces, and a Pro Bundle is available at $818 combining both categories with a $200 savings using promo code BUNDLE2026.

Savings claim: Up to $800 per year by eliminating laundry detergent and washing in cold water
Customer rating: 4.9 out of 5 stars from 226 verified reviews
Money-back guarantee: 100% satisfaction or full refund within 30 days (minus return shipping)
Warranty: 1-year manufacturer's warranty against defects
