The Ozone Laundry System: Pros and Cons, Does it Really Work? 

I don’t know if you’ve ever heard of an ozone laundry system. If you haven’t this is the post for you. My husband purchased an O3 Waterworks ozone laundry system last year. I didn’t honestly know how they worked, but now that we’ve been using it for over a year I have feedback for you.

Fun fact, ozone laundry units have been used in many commercial laundry systems including hospitals, hotels and nursing homes for years. Now it is available for household use. The natural cleaning powers of ozone infused plain water removes stains and odors rather than just covering the smell of dirty laundry with another scent. The ozonated water kills the germs that make your laundry smell bad. You can even use it to clean washable diapers.

Pros of an Ozone Laundry System

  • Save Money – While you will have the upfront cost of buying the ozone system, there is no need to buy detergent. Depending on how many loads you do per year, this can save you a lot of money. There is also no need to pay to heat the water that your washing machine uses. The ozone water works just as well in cool tap water which translates to energy savings. You will also find you won’t need to use fabric softener, your clothes will feel great without it.
  • No Odor – If you or your family members hate the scent of laundry detergent or are sensitive to smells, the ozone laundry system has no odor.
  • Easy to Install – My husband is NOT very handy, but he installed it in our laundry room without help in a short amount of time, about 30 minutes. All you need is a regular outlet. Everything else is included. It works with washers of any make.
  • No Chemicals – Even “clean laundry detergents” contain surfactants, solvents, and additives that are bad for the environment. This is one of the main reasons my husband wanted to purchase the ozone system.
  • Front Loading Funk Gone – I don’t have a front loading washing machine for one reason, the ring in my old one was really gross if you didn’t clean it regularly. I’ve read from other users that the ozone water prevents the funk from building up inside the plastic ring. This makes sense because ozone water is used as a disinfectant.
  • 30 day Money back Guarantee – You can try it out for 30 days and return it if you don’t like it.

Cons of an Ozone Laundry System

On my machine, which is a top loader, the machine has to have time between loads when you use the “boost mode” setting. It makes a bunch of clicking noises as it runs a dehumidifier cycle.

If you have a lot of fabrics that are not color-safe, they might fade more quickly.

How Does the Ozone Clean Clothes?

Not being really familiar with how ozone works, this was my first question. The machine has patented technology water treatment that infuses the water with high levels of ozone (aqueous ozone) as it goes into your washing machine. It uses a venturi injector which is a highly efficient means of mixing liquids or gasses into a stream of water.

That ozone in your water reacts with organic compounds and oxidizes them, kills the germs. This removes the organic compounds from your laundry and as an added bonus it removes detergent and chemical residues. Ozone is the 2nd most powerful of the oxidizing agents currently known.

Without ozone, you might feel the need to run a hot water wash cycle to get smelly laundry really clean, but ozone water means you don’t need warm water or hot water to get them clean.

What if You Have Hard Water?

This system is supposed to work with most water chemistry (hard or soft water) according to the manufacturer. I don’t have a water softening system in my house. The manufacturer says that it works fine with a home water softening system.

How Long Does It Last?

The answer to this depends partly on how much laundry you do. The system might need to be refurbished after 5 years, according to the manufacturer. It comes with a one year manufacturer parts warranty.

Is Ozone Water Dangerous?

No. My dentist uses ozone water every time I go. You swish your mouth out with it before you get your teeth cleaned. If it’s safe enough to go in your mouth, it’s OK for your laundry. As a matter of fact you can buy an aqueous ozone spray bottle to create a sanitizing solution to use on fruits and vegetables or even to clean hard surfaces in your home.

Health Magazine says “ozone has been used for hundreds of years to sanitize and purify water, and it’s also FDA-cleared to kill 99.9% of harmful germs. Better yet, the oxidizing agent turns back into water once it’s used, so you won’t have to worry about leftover contaminants. “

The bottom line is, I really love our Waterworks system, and what I love most is that I didn’t even have to install it. 🤣

  1. I was so excited when you told me about this!! I haven’t gotten around to getting one, but it is on my list!!

  2. We just installed ours and did my first load. I realized a smell after starting my washer. It’s not showing that it’s leaking Ozon but I’m super sensitive and can smell something in the air when running my washer. But I use short cycle and have my window open in laundry room. Like I said I’m super sensitive and it made me a little dizzy and it can cause asthma when you breathe it in directly. Also you should not open washer at all while it’s running to put more laundry in. We will see how it works but I’m usually also not in the room when the washer runs

    1. Sabrina,

      Interesting. I have an ozone machine that I use to remove things like paint fumes and it definitely has an odor when it’s in the air.

      I have NEVER noticed any smell from my laundry system. It is going directly into the water, but maybe you are smelling the water. I don’t believe that ozone water is harmful to smell. In fact, my dentist has me swish my mouth with ozone water every time I visit him.

      I hope this helps.
