The difference was noticeable compared to my regular tap water, which sometimes had a slight chlorine taste. I used the water for drinking, cooking, and even making coffee, and everything tasted fresher. It was also reassuring to know the UV light was working to kill bacteria and other impurities. The alkaline filter gave the water a smooth feel, and knowing it added minerals like calcium and magnesium made me feel like I was drinking something truly healthy.

The feature I found most impressive was the 11-stage filtration process, especially the reverse osmosis and UV light combo. It removed almost all the bad stuff like lead, fluoride, and bacteria, which gave me peace of mind. The alkaline filter was another highlight—it didn’t just clean the water but improved its taste and added essential minerals that are good for the body. The faucet was easy to use and looked modern, making it a nice addition to my kitchen. The 100 gallons per day capacity meant I never had to worry about running out of filtered water, even with daily use.
Long-Term Performance
After using the system for several weeks, it still worked perfectly without any drop in water flow or taste. The tank held enough water for my family’s needs, and maintenance was simple with the filter replacement reminders. I appreciated that the system stayed quiet and didn’t require much attention. Overall, it has been a reliable addition to my kitchen, providing clean, great-tasting water every day. I feel more confident about the quality of the water my family drinks, and that’s priceless.
