CVS Pharmacy – Santevia Water Systems Power Punch water mineralizer sent me a FREE sample of Sante Via Power Punch water mineralizer. Looks like round rock salt. Looks are wrong. Makes water taste better. Keep it in a glass full of water. Going to last for a while. no sign of melting. Thank you very much #SanteviaWaterSystems Power Punch water mineralizer. available at #CVSPharmacy –
