Review: Crystal Clear Water – Totally Worth It! - I've been using this reverse osmosis system for about three months now, and I can honestly say it's one of the best home upgrades I’ve made. The installation took a bit of time (about 1.5 hours), but the instructions were clear and all the parts were well organized. If you're even a little handy, you’ll be fine. Once set up, the difference in water quality was immediate. No more chlorine taste or weird odors—just super clean, fresh-tasting water. I use it for drinking, cooking, and even brewing coffee, and everything tastes noticeably better. It’s also been great not having to lug home bottled water anymore. The tank fills fairly quickly, and pressure is good. I also appreciate that it comes with a extra sets of filters. Only minor downside is the space it takes up under the sink, but that’s to be expected with an RO system. Still well worth the trade-off for the quality of water you get. Highly recommend if you're looking to ditch bottled water and want peace of mind about what you're drinking.

## Questions & Answers

**Q: How is RO water compared to bottled water?**
A: Just as good or even better. We use the same technology as other major bottling plants use to filter water. RO systems purify water daily in your home which is fresher and healthier compared to water that has been sitting in plastic bottles.

**Q: How effective is Reverse Osmosis filtration compared to other methods?**
A: RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is equalse to 0.00000004 inch! This is the technology used to make bottled water.

**Q: What is the WQA and what are the benefits of purchasing a certified system?**
A: To receive WQA Gold Seal certification, a RO system must be constructed to meet strict public health standards and pass weeks of rigorous testing for material and parts safety, structural integrity, and contaminant rejection performance.

**Q: What is the size of the product, and if I move, can I remove the system to bring with me?**
A: The dimensions are 17.5"H x 16"L x 5.25"W, and the tank is 11"W x 15"H. This system is very easy to uninstall. Just close the water inlet needle shut off, take off the water inlet tubing, and take off the whole system in 5 minutes.

**Q: How often do I need to replace the filters?**
A: The filtration process is optimized to protect the RO membrane, so the prefilters (the 3 filters before the membrane) can last between 6-12 months, and the RO membrane & post-filters can last between 12-24 months depending on incoming water quality.

### ⭐⭐⭐⭐⭐ Working as advertised!- and (18 month update) has kept on working flawlessly!
*by S***E on January 12, 2025*

We installed this system about a month ago. Instructions were clear, it was an easy project. Our TDS dropped from mid-400's in our tap water to about 40, easily 90%. I had noticed the reviews mentioning water leaks at connections, but I found them to be tight if put together right. Still, protection is always good, so I installed a very nice little automatic safety shut off valve by a company called Savant. Here's the link- https://www.amazon.com/gp/product/B08BCNX42F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Always pleased to get things that work! UPDATE 18 Months in use! The system has been flawless, no leaks, no malfunctions and we are still on the original filter set. Latest tests on the water quality compared to our tap water are still showing around 95% reduction in TDS, total dissovled solids. One of the reasons for the installation in the beginning was the discovery of just what was in the TDS of municipal tap water. Your local water company will have that data, I found mine easily online... and found arsenic, lead and a host of unhealthy things were allowed up a limit. Our tap water runs 450-500 PPM. The RO cuts that to the 25-30 range, and we use it for anything that will wind up in our bodies; drinks, cooking and so on. It tastes better too. Overall it has been a very good choice and investment.
