Reverse Osmosis Water Filtration Systems

Reverse ososis water filtration systems help improve drinking water by pushing it through a semipermeable membrane that reduces dissolved salts and certain other contaminants. Often called RO water filters, these systems typically pair the membrane with sediment and carbon filtration to catch particles and reduce chlorine taste and odor. For a home on city water or a rural property with a private well, a reverse osmosis drinking water system can be a practical way to treat water for drinking, cooking and filling the coffee pot. Performance varies by system, so check its certified contaminant-reduction claims against your water test results rather than assuming every RO system removes the same things. Some systems are certified to reduce contaminants such as lead, arsenic or nitrates, but reverse osmosis alone should not be counted on to make untreated well water microbiologically safe. Private well owners should test their water regularly and address any bacteria or other concerns with appropriate treatment. Choosing a reverse osmosis water filtration system starts with knowing how much filtered water your household needs and where you want it delivered. Under-sink RO systems treat water at a single location, while whole-house reverse osmosis systems require more planning, capacity and supporting equipment. Before settling on a setup, compare installation requirements, operating water pressure, daily water production and filter replacement schedules. Storage-tank models hold filtered water until it’s needed, while tankless designs make it on demand and may require an electrical connection. RO filtration also sends a portion of incoming water to the drain, so checking the system’s water-efficiency rating matters, especially where well output or water availability is a concern. Hard water, iron and heavy sediment may call for pretreatment to help protect the membrane and keep water flowing as intended. Staying on top of replacement filters, membrane care and sanitizing according to the manufacturer’s directions helps your home water filtration system keep up with everyday kitchen needs.
