I was going to go with a point of use RO, but I figured by the a whole house system will have a big up front cost but not having to buy 100 dollars in filters every year would be nice. The one I was looking at was the arsenic master 8 has anybody heard of this or does anybody have a good system for arsenic removal. The arsenic master is like 1300 and the guy said that it will last 10 years to maybe forever, is this right. please help
