Charla asks - I know this has been asked before, but I can't find the post. Our tap water has recently changed in taste ( I'm unsure why) so I am looking for suggestions about water filters, brands, companies, under sink vs. whole house, ect. Anyone that is reasonable and reliable that anyone has worked with? I don't think we have a problem with appliances or it leaving residue, it just tastes different. Thanks!! ~Jenny
