A reverse osmosis (RO) system removes a wide range of contaminants and impurities from water by forcing it through a semi-permeable membrane. This process effectively eliminates sediment, chlorine, fluoride, lead, arsenic, nitrates, sulfates, pesticides, herbicides, pharmaceuticals, bacteria, viruses, microplastics, dissolved salts, heavy metals (like mercury and chromium), calcium, and magnesium. The result is pure, clean, and great-tasting drinking water that’s safe for your family and appliances.

A reverse osmosis (RO) system requires minimal but regular maintenance to keep it working efficiently. Typically, the pre-filters (such as sediment and carbon filters) should be replaced every 6–12 months, while the RO membrane lasts around 2–3 years, depending on your water quality and usage. The post-filter (often a carbon filter that polishes the water) should also be changed annually. It’s important to sanitize the system once a year to prevent bacterial buildup and ensure clean, great-tasting water. With proper care, a reverse osmosis system can last for 10–15 years.

A reverse osmosis (RO) system typically wastes some water during the filtration process to flush away contaminants. On average, a standard RO system wastes about 3–4 gallons of water for every 1 gallon of purified water produced. However, high-efficiency models can reduce waste significantly, using as little as 1 gallon of wastewater per gallon of filtered water. While this might sound like a lot, the trade-off is clean, great-tasting, and contaminant-free drinking water.

A reverse osmosis (RO) system is most commonly installed under the kitchen sink, where it connects to your cold water line, and has a dedicated faucet for purified drinking water. The system includes several components — filter cartridges, a membrane, a storage tank, and a drain connection — all neatly fitted inside the cabinet. Some homeowners also choose to install RO systems in basements or utility rooms if space is limited, running a line up to the kitchen faucet or refrigerator. No matter where it’s installed, an RO system delivers clean, great-tasting water right where you need it most.

Yes — a reverse osmosis (RO) system can slightly affect both water taste and water pressure, but in beneficial ways. It greatly improves the taste of your water by removing impurities such as chlorine, lead, fluoride, and dissolved minerals, leaving it clean, fresh, and pure-tasting. However, because the water passes through multiple filters and a fine membrane, it may cause a small drop in water pressure at the RO faucet. Most modern systems are designed to minimize pressure loss, and you can use a booster or permeate pump to maintain steady flow if needed.
