Product review (1 stars):  This company continues to advertised this item on Amazon ...
 This company continues to advertised this item on Amazon as (Based on water quality and Contaminants level filter lasts up to 6 Months or 500 gallons.), when the item actually only treats 300 gallons of water as stated on the companys website (Based on water quality and Contaminants level filter last up to 6 Months - 300 gallons) and on the product label. A Very Deceptive advertising practice.
