Customer Reviews
Always a reliable choice
This is my third purchase from O3 Waterworks. I've been using their Laundry System for years and just got the Sanitizing Spray Bottle this time. The laundry system is still great, and the spray bottle seems just as good. They're consistent with quality and shipping times, which is why I keep coming back. Never had an issue with any order.
Got the spray bottle, it's alright
Needed something for quick clean-ups, so I grabbed the Sanitizing Spray Bottle. It came pretty fast, like 4 days to my house. It's easy to fill and use. Not sure if it's like super powerful, but it does make things feel cleaner. Good for daily stuff around the house. No complaints, it's just a spray bottle, ya know?
Great value on the bundle
I was looking for a new cleaning solution and saw the Chemical-Free Cleaning Kit. It felt like a good deal. The bundle savings definitely made it worth trying. Everything arrived packaged well, and the products seem to do what they promise. I compared prices with a few other brands, and this kit offered the most for my money. Happy with the purchase, it felt like a smart buy.
Love the laundry system!
OMG, I just received and installed my Aqueous Ozone Laundry System and it's amazing! My clothes feel so fresh and clean without any harsh chemicals. The installation was super easy too, took about an hour with the kit. I can't believe how much money I'll save on detergent. This is a game changer for sure. Everyone needs one of these! I am so happy with this purchase!
Good cleaner, fast ship
Bought the Multi-Surface Ozone Cleaner. Arrived quick. Works well on kitchen counters. Simple to use, no complaints here. Saved me from buying other sprays.
Decent, but slow shipping
I ordered the Deodorizing Spray and it works quite well for pet odors, which was my main concern. The product itself is effective, I'd say 5 stars for that. However, the shipping took about 8 days to reach me in California, which felt a bit long for a small item. Tracking updates were also a bit sparse. Overall, I'm satisfied with the spray, but wish delivery was a little quicker.
O3 Waterworks Community Discussion
Share tips, ask questions & help fellow shoppers save more
Does anyone know if O3 Waterworks offers a discount for nurses or healthcare workers? My sister is one and she's trying to save some cash.
Is O3 Waterworks better than something like LaundryPure? Trying to decide between the two for a new laundry setup.
Can you use more than one promo code at checkout? Got a referral link from a friend but also saw a newsletter signup offer.
Thinking about getting the laundry system. Does it really save that much on detergent? And how long does that thing actually last before I gotta replace it?
So how easy is it to return stuff if I don't like it? Like, if the laundry system just isn't for me, is it a pain to send back?
