I use undercounter 2 stage filter in the kitchen. Works great. The filter replacement takes 6 minutes. No tools needed. Lasts about 5 months before flow gets slow. YMMV.
Pros: Clean taste, Easy to install, Long lasting filter
I did a lot of research before I decided on Aquasana. It was by far the best! I started with the counter top system & later upgraded to under the sink & it has it's own faucet to install on your sink. Easy installation even if you don't have a spare hole on your sink. Instructions are great. My husband & installed it in no time! It also has a faster water flow! I would not be without this filtration system! The difference it has made in our water is almost unbelievable! I use to buy my water, now I don't have to. I also give this filtered water to my inside dogs. I highly recommend this system to anyone that is looking for a filtration system! You won't regret it!
Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter, Used for years & wouldn't be without it!
