With the city we live in, our city is rather ignorant about water quality, so they add Chloramine. To remove this chemical I found that the Aquasana product showed removal. So I ordered only what we needed as a package to remove our contaminants and when it arrived I installed it. Very easy installation and the filter removes all the Chloramines. Can't believe the filters are so small and yet so much better than the Brita System we used before to try and filter the city chemicals.
My only real issue was in the installation of this as a replacement. My original filter/fixture was installed with a new sink/cabinet. (Plenty of access to install the spigot and filters) Replacing the new spigot is more than difficult without tearing out the entire sink to access the old faucet due to location and cabinet opening size. If you added a spacer for the stem of the faucet and standard tightening nut to the installation parts the replacement installation would be easier.
Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter, Much Better Design, Simpler Maintenance
