Has to be RO filter if it is a 5 stage. As long as it has an RO in it then it will filter the nanomaterials at least. The RO we have tested and works well for 2 months. Any fikter being used has to go down to the nm range or it will NOT WORK at all. This is tried and tested. Those who wish can make their own assumptions if they are willing to. I'd go with what is known and works personally.
