Why reverse osmosis?
Climate change, urban growth, and industrial pollution are stressing freshwater supplies nationwide, and aging infrastructure can reintroduce contaminants after water leaves treatment plants. Reverse osmosis is the most thorough water filtration technology available for the home.
How it works
Reverse osmosis pushes water through a semi-permeable membrane under pressure. The membrane's tiny pores allow only water molecules to pass while trapping contaminants like heavy metals, chemicals, pathogens, and dissolved solids. The result is clean, safe, great-tasting water.
What RO removes that municipal treatment often can't
Heavy metals
Lead, mercury, and arsenic that can leach from aging pipes and industrial runoff.
PFAS: "forever chemicals"
Synthetic compounds used in nonstick cookware, waterproof fabrics, and firefighting foam. They persist in the environment and body for decades and are linked to cancer, thyroid disorders, and reproductive problems.
Endocrine disruptors
Phthalates, pesticides, and disinfection by-products that interfere with hormone balance. Standard municipal treatment can't reliably remove them.
Microorganisms
Bacteria, viruses, and protozoa that can slip through aging infrastructure.
Chemicals
Chlorine, VOCs, and pesticides, plus nitrates from fertilizer and sulfates from industrial waste.
