Arsenic Removal
We live by the Chesapeake bay and tested positive for arsenic after drilling a new well. This unit removed the arsenic to allowable potable water standards. Highly recommend!

Verified Purchase
Purchased from Walmart and it's very clearly been used before. Unsealed filters, scuff all over the unit, and dusty. In the future I won't buy from Walmart as I no longer trust that the items are new
