OxiOrg O³ Pro Ozone Laundry System

An ozone laundry system adds ozone, a strong natural oxidizer, to your washing machine's cold water as it fills, so everyday soil and odors lift in cold water with far less detergent. The OxiOrg O³ Pro is our premium model. It mounts on the wall above your washer, treats the cold water on its way in and turns on by itself with every wash.

Activated ozone and magnetized water conditioning work together to freshen your laundry and eliminate odors with a fraction of the detergent. Color-coded lights show your ozone level at a glance, and a dryer cartridge you change yourself keeps it running at its best.

At a glance

• Cleaner, fresher laundry in 100% cold water: eliminates odors and enhances sanitation, with no hot water
• Improves detergent efficiency: use significantly less detergent, or none at all
• Three ozone levels with color-coded lights: High (blue) for whites and stubborn stains, Low (green) for linen, silk and delicates, or Off
• Gentle on fabrics at the recommended levels
• Automatic: chimes at power-up, starts every wash on High and returns to standby when the water stops
• Replaceable desiccant dryer cartridge: side lights glow blue while it works and turn red when it is time for a new one
• Leak sensor with a buzzer and automatic shutoff
• Both 1/2" and 3/4" inlet hoses in the box to fit your faucet
• Installs in about 15 to 20 minutes on the cold line, no special tools

Which OxiOrg is right for you?

Both models use the same ozone levels (0 to 1.2 mg/L, High, Low or Off), connect to the cold line at 20 to 60 PSI, detect leaks and carry the same 1-year warranty. Here is where they differ.

How it works: the technology inside

Ozone made and mixed in as you wash

Cold water flows from your faucet into the unit, through it and on to your washer. A flow switch senses the water and turns the unit on automatically in High mode. The oxidizing module produces activated ozone, and a venturi in the water path blends it into the cold water on its way to the drum. When the water stops, the unit returns to standby.

Magnetized water conditioning

The built-in magnetizer treats the water as it flows to the washer, for a softer wash. It stays on even when the ozone is set to Off.

A desiccant dryer cartridge

Ozone generation works best with very dry air. The O3 Pro uses a replaceable desiccant dryer cartridge. When the side lights turn from blue to red, twist the old cartridge out counterclockwise, twist the new one in clockwise, then hold the top and center keys until the unit chimes.

Oxidation: how ozone cleans

Ozone (O3) is oxygen with a third atom attached, and that extra atom makes it eager to react. When it meets organic compounds it breaks the bonds holding them together. Sweat, body oils and the compounds that make towels smell musty or sour are all organic, so ozone helps break them down and the rinse carries them off. Wastewater plants rely on ozone for odor control for the same reason. It does not stick around: ozone turns back into ordinary oxygen soon after it forms.

Ozone and disinfection: the science

Water treatment plants use ozone as a disinfectant. It oxidizes the outer walls of microorganisms, and its effect depends on how much ozone is present and for how long. The OxiOrg O³ Pro applies that same oxidizing action in your washer's cold water to eliminate odors and enhance sanitation.

Brighter colors

Leftover detergent builds up in fabric over time and can leave colors looking flat and towels feeling stiff. With the O3 Pro you use much less detergent, so there is less to build up, and washing in cold water skips the heat that is harder on fabrics. That is how ozone laundry helps keep colors looking their best.

Less detergent

Because ozone handles much of the cleaning, the Pro lets you cut detergent significantly, and some loads need none. We recommend half your usual amount for the first few weeks while old buildup rinses out, then trimming further if you like what you see.

Cold water saves energy

Heating the water is where most of the energy in a hot wash goes. The O3 Pro is built for 100% cold-water operation, so you save energy with every load.

Who it is for

• Households that want the premium setup: clear color-coded lights and a cartridge you can service yourself
• Busy families that run a lot of loads and want to stop heating wash water
• Households tired of detergent buildup on towels, bedding and gym clothes that hang on to odors
• Front-load and top-load home washers on a cold line at 20 to 60 PSI, with a grounded outlet within reach

Not for: hot water lines, drinking water, outdoor installs, or commercial, industrial or rental laundry. It still works in water harder than about 7 grains per gallon; a water softener or pre-filter gives the best results.
