How to best protect from water pollution?
Reduce your water pollution exposure in California
Carbon Filter
Carbon filters are effective at removing many common contaminants including chlorine, sediment, volatile organic compounds (VOCs), and improves taste and odor.
Reverse Osmosis
Reverse osmosis systems can remove up to 99% of dissolved contaminants from water including heavy metals, fluoride, nitrates, and arsenic.
