Pure when cold.
Ok, I've had this for a few months... and I'll say I'm fairly happy with it. I gave it 5 stars because it does what it says, but I'm only "fairly happy" because of the way it works isn't conducive to where I live, and some bleaching. So, yes it bleaches items. That's what it is... more clearly it oxidizes things, and does what hydrogen peroxide would do, conventionally bleaching. What I did notice was that it tended to bleach items that had their colors not washed before, or not set fully. So here's my suggestion, wash new items in hot water first, then wash with the O3 water on cold. When it works, it actually leaves clothes smelling oddly fresh. Like there's no soap, there's no scents, only water; so how does my clothes actually smell good? Magic apparently. I can't explain it. It has a slight ozone smell, but after that fades, it smells like fresh linen... Now my biggest problem, and the main take away from owning one of these, you CANT use hot water, at all. You can't even use warm water at all. The oxygen is dissolved in the water, like carbonation is dissolved in your soda (seriously.) Warm water doesn't let gasses, like oxygen or carbon-dioxide, stay dissolved in it. So in order to have high concentration of oxygen to clean the clothes, it has to be cold... best if it's refrigerated, like a soda. (Yes, soda under pressure can be warm but once removed from the can the gasses will condense out of it as quickly as it can. Unless you've cooled it first.) During the winter, this system worked great for me. Water is cold from the tap, and oxygen is dissolved in the water well. But during the summer, in the Mojave desert, even the tap water gets warm... like "I would enjoy a soak in this warm water" warm. As the summer approached, my clothes and sheets didn't smell "as good"... uh oh... the water is too warm for this to work anymore. To solve this, I've kept using the cold water, but I've added a single thing of detergent. There's "enough" oxygen dissolved to do a good amount of disinfectant work, and the soap should cut through the rest. So, for me, it's not a magic bullet... however it did cut my detergent use down to only during the summer. Minor bleaching effect can be mitigated if you remember about it with new items. If you live in a cold climate, or have cold water all year round, you're in luck. You can literally stop buying detergent with this... which is good if you want to stop polluting the water table with soaps, want less chemicals on your skin, and want actually ^disinfected^ clothes. Soap doesn't disinfect or kill germs, it just helps remove them by making water able to release them. Ozone breaks down the cell walls of germs and bacteria, and destroys them, not just killing them... it's as good as bleach at disinfecting, but without (always) destroying colors. However, the upfront cost is the biggest bug for me. How many loads of laundry can you do, adding the cost of heating the water and the soap use, to match the upfront cost of the unit? Probably a few years worth. At about $0.25 a load for detergent, and lets say $0.25 for heating water also... that's about 600 loads, for me 4 loads a week, that's just under 3 years of laundry (probably a lot more depending on the water heating costs, or less depending on how much laundry you do, also depending on the price you get the system at.)

In use for nearly 4 years
This is the best small appliance investment I have ever made. Nearly four years of heavy use, and I can say without hesitation that this has more than paid for itself 2x. I’m amazed how it gets what are typically very problematic stains out of every type of fabric safely. With a family of kids active in all kinds of sports, we have had every type of grass and dirt stain, ketchup, wine, chocolate, blood, you name it, on every type of fabric, from denim to cotton towels to dry-clean only delicate fabrics, and the ozonated cold water has gotten every stain out completely every time. There was one time where we had to run an item through the was three times to get a stain out. Otherwise, a single wash cycle has always worked to completely remove every kind of stain (just be sure to wash an item right away before the stain has time to set). What I have noticed most, though, is how much better this ozone generator works on white cotton. Specifically, white cotton T-shirts and cotton towels stay far whiter than when we used to use hot water and laundry detergent and bleach. T-shirts in particular would gradually turn gray or slightly yellow, and the material would get thinner and thinner. The cold ozonated water prevents this discoloration and fabric deterioration. Cotton comes out much softer as well because, unlike detergent, bleach, and fabric softeners which damage cloth fiber and leave small amounts of residue, the ozone simply evaporates as oxygen molecules leaving nothing behind and without breaking down any of the cotton fiber. My T-shirts in particular look brand new after more than a year (same brand, same material as before). Fabric washed with cold (never hot) ozonated water also leaves fabric much, much softer than detergent and fabric softener. Ironically, fabric softener is actually harmful to fabric and causes it to deteriorate (hence the softening). You will notice a difference, too. Since the ozonated water leaves no residue, once you use any fabric that has been washed with detergent and fabric softener will feel odd. It’s hard to describe, other than to say if you ever touch a dryer sheet, you can feel a weird residue on your skin. You will notice that’s not present with items washed in ozonated water. Terry cloth in particular also feels softer. Once you go back to terry cloth washed in detergent and fabric softener, you’ll immediately notice that it feels more coarse. BEST OF ALL, ozone has been used for decades as a commercial laundry alternative to detergents, bleach, and fabric softeners. It has only been recently that ozone generators like this one could be cost-effectively produced for residential laundry use. Ozone is environmentally safe - the ozone generator produces ozone (oxygen molecules) from the water without adding any chemicals. Ozone naturally cleans, deodorizes, and disinfects, and then dissipates back into the water leaving nothing behind. Ozone has been used for decades to treat city water around the world because it is an environmentally safe alternative to adding chlorine or other chemicals to water (bleach is toxic to all water life forms, and does not naturally break down into safe chemicals, and detergent - even “plant based” ones - contain chemicals that are harmful to aquatic life forms). Since most laundry odors are caused by bacteria, ozonated water is extremely effective at disinfecting fabric and killing harmful odor-causing bacteria, unlike detergent and fabric softeners which use artificial additives to cover the smell of odors without killing the odor-causing bacteria. A couple of important tips (these are in the user manual): 1) ONLY use cold water. Never use warm or hot water with the ozone generator. Warm and hot water cause the ozone in the water to dissipate quickly, which prevents it from cleaning and disinfecting your fabric. Just disconnect the hot water hose from your washer. You won’t need it, and your washer will operate correctly without it connected. Using hot or warm water unnecessarily wastes money and prevents the ozone from naturally cleaning and disinfecting. 2) NEVER use any kind of detergent, fabric softener, bleach, stain treatment, or oxy-powder of any kind (no baking soda, either). Each of those interacts with the ozone and makes it far less effective at disinfecting and cleaning. Using these just wastes money and defeats the purpose of the ozone. 3) If you have a troublesome stain, like blood, wine, grass, dirt, chocolate, etc. - get the item into the wash as soon as possible, but NEVER pre-treat it with any kind of soap, detergent, or stain remover. You might need to run the item through a second cycle BEFORE drying it. 4) We have safely and successfully used our front-load washer to remove stains from some delicate dry-clean only fabrics. I would NOT use a top load washer with an agitator for any delicate dry-clean only fabric. Although the ozonated water does work for fabrics like rayon and polyester, you should NOT try to wash 100% wool or silk. Take those to a dry cleaner and let them try to get stains out. In the nearly four years of heavy (almost daily) use of our ozone generator, we have reduced our monthly gas bill by more than 20% since we are no longer using warm or hot water for laundry, and we have eliminated a half dozen laundry detergent / bleach / pre-wash / oxy powder / dryer sheet products, saving well over $400. I would absolutely recommend this product, whether you want cleaner, softer, longer-lasting clothing; fresher smelling laundry; whether you want to save money; or whether you want an environmentally responsible alternative for your laundry; or a combination of these. Hands down, the best small appliance purchase I have ever made.

Cleanest Clothes Ever!
This works so well!!! I no longer buy or use any laundry soap. Our clothes smell so clean, towels are soft and fluffy! It is easy to install, and we even moved, and it moved easily along with our washer and dryer!

Every home should have one!
We were skeptical, to not use hot water or laundry detergents, but the O3 Pure Eco Laundry System really does replace them. Clothes come out clean, fluffy and smelling fresh. And sheets truly come out brighter than ever before. Have you ever left washed clothes in the washer too long and have to wash them again because they smell, or open an empty front load washer and smell the mold and mildew? Not anymore! By replacing all of the chemicals (read the ingredients of all of the laundry chemicals you use) with ozonated water (oxygen molecules), you are disinfecting the odor-causing bacteria from your clothes and washer. We have eliminated laundry detergent, bleach, fabric softener and dryer sheets and we are going to stop using spot remover even if we have to wash something a second time. Your clothes will last longer; just watch how much LESS lint is in the dryer trap. And if you have allergies to the harsh chemicals in laundry products, the O3 Pure is a must. Imagine, no more chemical residue left on your clothes. Installing the O3 Pure was easy. The step-by-step instruction card and install video made it a breeze. It took about 15 minutes to mount and connect it to the washer and that’s it, no maintenance or supplies. It only comes on when the washer is filling or rinsing. And while the technology was new to us, it was comforting to know it has been used for decades by hospitals, laundromats assisted living, sports facilities, hotels and more. Just make sure you use cold water. It does not work well with hot or even warm water because those dissipate the ozone quickly. When in use, you will see a green light indicating a standard load of laundry. If you have heavily soiled clothes, you can push the button on the front to blue for more ozone cleaning power. It’s just one more step we’ve taken toward greener living.

GREAT FOR FARM LIFE
I live on a farm with 4 big dogs. Life is MESSY, I often have to deal with mud, grease, oil, diesel and who knows what stains. For the really tough stuff Id soak them in the bathtub to try to get the stains and funk out. Not anymore. This changed my life. It has two settings, Normal(green) which I call Ozone. and EXTRA STRENGTH. Which I call WHOA-Zone. WHOA-Zone gets the job done. I had bedding that my dog expressed her glands on(anyone can tell you that is NAAAASTY) Whoa-zone got it gone. NO DETERGENT!! you will smell it some when you use it, my laundry room has a vent fan in it, and is behind a closed door. When i use the stronger ozone, i turn the fan on and close the door. My clothes are clean, soft and smell like nothing. I use a fabric softner sheet in the dryer to help with the dog hair(4 BIG DOGS) and that gives it a nice smell. Which I had gotten this sooner. You will notice a bit of an off smell the first couple times you run it, no on your close just in the air when the machine runs. that is the residue built up in the machine being blasted away by the ozone. Easy to install, I did it by myself and I'm a short girl who is not super handy.

It's GOOD
UPDATE: we originally purchased this (3 Pure) in December 2024 for the new home we were building. We were very disappointed when we opened it up and installed the unit. It leaked and pretty flooded our laundry room. We called the company, and they were willing to have us return it for a new unit, which they did! We installed the new unit, and so far, it is operating as described. The first load was washed without any problems. To have the option of washing without laundry detergent is wonderful! Imagine having to use detergents that ruin our fabrics and destroy the clothes we pay SO much money for. In addition to harming our garments, the fabric detergents use harmful chemicals and perfumes that cause irritants to the skin! Thank you for working with us, and please, if you are thinking of this type of laundry buddy to save your clothes and the environment, buy this unit for your home!

Fresh Laundry, No Detergent Required: My Clothes Have Never Smelled This Good
I’ll admit, I was pretty skeptical about the O3 PURE Ozone Eco Laundry System at first. I mean, washing clothes without detergent? But wow, was I in for a surprise! After giving it a try, I’m absolutely blown away by how fresh my clothes smell—it's honestly amazing! Setting up the system was a breeze. The directions were clear and easy to follow, and it took me just 10 minutes to install it myself—no special tools needed. It attaches right to your existing washing machine, and the best part? No maintenance required. It only kicks into action when your washer is filling or rinsing, so it’s not wasting energy. Plus, it uses less than 45 watts of electricity, which is a win for my utility bill. For anyone with sensitive skin, this is a dream come true. No more worrying about detergent or chemicals—this system lets you wash your clothes with just cold water and still get them super clean. And if you’ve ever had to deal with the smell of mold or mildew, this thing wipes those odors out completely. The O3 PURE is more effective than the older ionic technology, and it comes with a true 3-year manufacturer parts and labor warranty, so you know it’s built to last. It’s also CE and RoHS certified, which gives me peace of mind knowing it’s safe and eco-friendly. All in all, I couldn’t be happier with the results. My laundry has never smelled fresher, and I love that I’m doing it without any harsh chemicals. My Rating System Explained: ⭐️ 1 star - Unfortunately, this product falls short of expectations due to its poor quality.

Clearly returned package with damaged looking product inside
Clearly received previously returned product. The box was destroyed but the outer shipping box was fine. The unit was opened and looks to be damaged. Most of the inner box foam was damaged. Really disappointed after it was already shipped late.
