I've had an Aquasana for 10 years now, and would NOT be without one. The old system worked well but was a real headache come filter-change time. The new, upgraded sink top system changes all that. Changing filters is as easy as opening a jar of pickles. just unscrew the holders, replace the filters and screw back on--NO TOOLS NEEDED! I'm not a plumber, so I would recommend the sink-top faucet be professionally installed. Once it's installed, you'll NEVER have to buy bottled water again.
Pros: Clean taste, Durable, Easy to clean, Long lasting filter
Here's what I love about this system: it's a super easy way to know that my water is free from toxins. I don't want to have to mess around with difficult or outrageously expensive systems. After doing research and using this product, I feel confident that my water is clean!
The new style cartridges are very difficult for me to replace. The hard twisting effort required is hard on my hands-very painful since I've developed a painful form of arthritis within the last 2 yrs. Hope you develop a useful wrench type device for these cartridges.
