    Ever since I put it in it tastes like chemicals
  

*by E***. on Reviewed in the United States on April 26, 2019*

Ever since I have installed the filter it tastes worse than the regular tap water.  There is a chemical taste that hasn't gone away.  It has been in for a month.  I keep waiting for it to taste better, but it doesn't.  I ordered a bone char filter and am going to have to throw this one out.  Big waste of money.
