Arsenic is a contaminant usually found in the earth’s crust. In excess amounts, it can make its way into surface and groundwater through industrial processes like mining.
Arsenic is tasteless and odorless and can go undetected in your water.
Consumption of arsenic-contaminated water can lead to dreadful health results such as vomiting, diarrhea, skin discoloration, stomach pain, blindness, and partial paralysis.
Long-term exposure to this chemical can also lead to death.
To prevent these side effects, you need to find ways to remove this dangerous contaminant from your water.
And a reverse osmosis system is your best bet!
Reverse osmosis systems filter water in multiple stages, removing even the most stubborn water contaminants.
The units have a semi-permeable membrane with very tiny pores that allow water molecules to pass through but trap larger molecules from contaminants like arsenic and lead.
To help you get the best reverse osmosis system for arsenic for your household, we have compiled this detailed review. Keep reading to make an informed buying decision.
