The generator works great ... my pool is crystal clear with pretty much no chlorine use. I highly recommend it. I actually liked it so much that I bought a second unit for my Koi Pond. It's unbelievable how great my pond looks!! Review: Best Ozone Generator on the market - You may ask why am I only giving them 4 stars instead of five? Because the check valves that come with the unit can not handle the Ozone. I have owned several different ozone generators on different pools over the past thirty years and they are awesome, this one is the best. Way better than the Dell Ozone units that I have had and like I said, my only complaint is with the check valves, for ozone you need teflon, most other plastics will fail in a short amount of time. I did find a reasonably priced stainless steel two piece (serviceable) valve body with teflon seal for about ten bucks, I just wish that they had included it so that I didn't have to search the internet for one. Again, great unit! Best that I've ever owned and would gladly buy another for my next pool (house). ## Features - Reduce chemical usage by up to 95% - 3 G/H Adjustable Ozone Concentration - Variable Ozone Output (10 - 100%). - PTFE tube for O3 outlet. - Air cooled Corona Discharge (low maintenance chlorine alternative) - Requirements: External Air Pump (or Oxygen Generator) and a venturi injector. - No more irritated, red eyes. No discoloration or dry brittle hair! No more smell of chlorine on your skin! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00L813C64 | | Best Sellers Rank | #823,602 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #532 in Swimming Pool Chlorine Alternatives | | Customer Reviews | 3.9 3.9 out of 5 stars (43) | | Item Weight | 14 pounds | | Item model number | SP-3G | | Manufacturer | A2Z Ozone Inc | | Product Dimensions | 18 x 12 x 15 inches | ## Images ![SP-3G Ozone Generator - Image 1](https://m.media-amazon.com/images/I/91Rp3ZLNLTL.jpg) ![SP-3G Ozone Generator - Image 2](https://m.media-amazon.com/images/I/51VBmiJY75L.jpg) ![SP-3G Ozone Generator - Image 3](https://m.media-amazon.com/images/I/61rqolXEndL.jpg) ![SP-3G Ozone Generator - Image 4](https://m.media-amazon.com/images/I/61UZ8sIP8bL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing product *by A***. on July 16, 2018* Absolutely the best thing I've done for my pool since I've owned it.

I was replacing an older unit (another make), so had basic understanding of operation & hook ups. Did have to install a 120v plug as other unit was direct wired. Appears to be doing the job as designed. ## Frequently Bought Together - SP-3G, 3g/hr Swimming Pool Water Ozone Generator, Cleaner, and Purifier Restores Clear, Chlorine-Free Water, Keep Water Crystal Clear,10,000 gallons Water Capacity - Pvdf Venturi Injector 3/4” Inch Gas-Liquid Mixing Venturi Injection for Ozone Generator, Ozone Resistance, Venturi for Pool and spa generators --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/16199896-sp-3g-ozone-generator](https://www.desertcart.co.uk/products/16199896-sp-3g-ozone-generator) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
