What Should I Look for when Buying a Reverse Osmosis (RO) System
Millions of households in the U.S. have installed reverse osmosis (RO) filtration systems to not only improve the taste and odor of their drinking water, but also as a preventative measure to keep their families safe from lead, pesticides, chlorine, too much fluoride, organics, and other contaminants.
How to Choose the Right Reverse Osmosis System
When purchasing a reverse osmosis drinking water system, you might consider several factors, such as the system's established reputation, pricing, ease of filter replacements, and more.
Before buying a reverse osmosis (RO) system, identify your water contaminants, ensure you have under-sink space for the tank, and understand that RO systems waste water (1:3–4 ratio). Essential factors include opting for a remineralization stage for better taste/health, choosing NSF-certified systems, and budgeting for annual filter replacements (pre/post-filters every 6–12 months, membrane every 2–3 years).
