There was a water purifier that I used before, but it seems to be too old.
I'd like to buy a new water purifier this time, which one would be good?
Brita and undersink seem to be famous, so please compare them.

Britta is a method of passing through the filtration membrane once, so I'm not sure what the water purification effect will be.
If the water purification function is too good, the water is said to be bad because it filters out all the necessary inorganic substances
