1. Do I need to buy the filter cartridge and the mounting adapters together with the water purifier?
One filter cartridge and mounting adapters are included in the water purifier.
2. Do I need plumbing work to install the unit?
You don't need the plumbing work. You can install it by yourself easily.
3. Once we install the product, will it block your view of the sink?
It is so compact that height between the end of a faucet and the shower outlet of SB151 is just 45mm. It saves space and doesn't block your view of your hands when using the sink.
4. Will it add a heavy load to a faucet when the water purifier is installed?
It is very light, only 300g (SB151).
