## 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.
