Questions We Get a Lot
A reverse osmosis system uses a semi-permeable membrane to remove dissolved contaminants like lead, fluoride, and nitrates from your drinking water, typically installed under the sink at a single point of use. A whole house filter treats water at the main supply line, targeting sediment, chlorine, and iron before it reaches any faucet or appliance. Many homeowners use both together for comprehensive coverage throughout the home.
Filter replacement schedules vary by stage and water usage, but pre-filters and post-filters on most RO systems are typically swapped every 6 to 12 months, while the RO membrane itself can last 2 to 3 years under normal conditions. Each product page lists the recommended service intervals for that specific system. Staying on schedule helps maintain flow rate and filtration performance.
GPD stands for gallons per day, and it describes how much filtered water a system can produce in a 24-hour period. For a typical household of 2 to 4 people, a system in the 100 GPD range is usually sufficient for drinking and cooking needs. If you run a larger household or want to supply a secondary line, our 600 GPD tankless system is designed specifically for high-demand use.
We offer free shipping on most orders within the Continental U.S. (excludes AK/HI), so your system ships to your door without added freight costs.

About Our Reverse Osmosis Systems
HeadSpring Water's Reverse Osmosis Systems are designed for homeowners who want reliable, great-tasting water without the guesswork. Our under-sink RO systems range from a 5-stage NSF/ANSI 58 and 372 certified option with a lead-free faucet and leak detector, to a 6-stage alkaline system with a 100 GPD capacity, to a high-performance 600 GPD tankless design built for larger households. Each system uses a semi-permeable membrane to filter water at the molecular level, reducing dissolved solids, lead, chlorine, and other common tap water contaminants. Pair any RO system with one of our dedicated filtration faucets, including brushed gold, brushed nickel, and matte black finishes, to complete your setup with a look that fits a modern kitchen. Whether you're upgrading from a pitcher filter or replacing an aging unit, our collection is built to make clean drinking water a permanent fixture in your home.
