Arsenic is one of the easiest contaminants to overbuy for and one of the easiest to under-treat if you shop casually. The safest middle ground is usually straightforward: buy a solid reverse osmosis system and treat the tap you actually drink from.

Best Overall: Waterdrop G3P800
If you want the cleanest answer for arsenic without turning the whole house into a treatment project, this is the recommendation. It solves the kitchen-tap problem directly and gives you broader protection against other high-priority contaminants too.
Best Value: APEC ROES-50
This is the straightforward budget option. It gets you into the right treatment class without requiring premium spend.
Best Pitcher: Clearly Filtered
Only use a pitcher as the arsenic recommendation if you need low installation and low friction more than maximum margin. It can be a starting point, not the gold standard.
Our Bottom Line
For arsenic, start with reverse osmosis unless there is a clear whole-house reason not to. The Waterdrop G3P800 is the best overall pick. The APEC ROES-50 is the best value pick.
