Whirlpool reverse osmosis system replaced after 14 years of use. The reverse osmosis unit started leaking and at this point I was looking for alternatives to reverse osmosis, thinking that the extra hoses and nozzles (which always had some moldy buildup in the spout) might have minimized the cleaning effect. Additionally, studies show that after 20 years of using reverse osmosis water, it removes "too many beneficial minerals" that your body actually needs. Try the Frizzlife Direct Water Filtration System. GREAT! I like that it's straight (no extra water storage). Because of this, the water comes out cold. Well! It has a higher flow rate than RO and will not run out when filling company jugs with water. And whether the research is correct. This is the healthiest water! Taste? Wonderful! After all, this is the essence. Main account here.Installation? Nearly perfect. Vicinity. In addition to the shrinking space under the sink, installation is easy. The only problem was that the filtered outlet tube options (16" and 32". Nice that they made both lengths available!) didn't work with my layout. I needed a tube with female connectors on both ends, not just one. So my wife went to Low to spend the extra $10. Voila! The price is way better than all the "unhealthy" (wink, wink!) reverse osmosis options. I wish this had been out 20 years ago! With this device everything is a WINNER! Oh yeah. and the Revain shipping is so fast! UPDATE 11/23/2021: Just wanted to say that this device is still AMAZING! I will continue to purchase Revain replacement filters and have been pleased with the quality of the product (and the resulting water!). Keep it up Frizzlife!
