There is no flat price for a reverse osmosis system, because the right configuration, under-sink or whole-home, number of filtration stages, and alkaline enhancement, depends entirely on your free water test results and what you are trying to fix. A test that shows only mild taste or chlorine issues might only need a simpler under-sink setup. A test that shows higher TDS, PFAS or 1,4-dioxane concerns may call for a more thorough configuration. We will walk you through the recommended setup and a specific quote after your test, never before it. ## Your tap water might be the reason you buy bottled If your water tastes like chlorine, leaves a metallic aftertaste, or you simply do not trust what is coming out of the faucet, reverse osmosis targets exactly that water, at the tap where you drink and cook. This matters most where drinking water contaminants are a documented local concern, including PFAS in Rockland and Orange County and 1,4-dioxane in parts of Long Island's groundwater. - Tap water tastes or smells like chlorine - You buy bottled water because you do not trust the tap - PFAS or 1,4-dioxane concerns in your local water supply - A metallic or chemical aftertaste - You want alkaline, mineral-balanced water for drinking and cooking - White scale showing up in your coffee maker or ice tray ## A multi-stage system built around your test ### Pre-filtration stage Removes sediment and chlorine before water reaches the membrane. ### Reverse osmosis membrane A semi-permeable membrane targets a wide range of dissolved contaminants. ### Alkaline remineralization A final stage restores beneficial minerals and a healthy, balanced pH. ### Under-sink or whole-home Choose a single dedicated faucet or treat drinking water throughout the house. ### Dedicated drinking faucet A separate tap for filtered water, installed alongside your existing sink fixtures. ### Clear filter replacement schedule We tell you exactly when filters need changing, no guesswork. ## From free test to your first glass ### Free water test We check TDS, chlorine, pH and other factors that determine the right RO configuration. 45 to 60 minutes - 1 ** ** ### Review your results We explain what your water needs and recommend under-sink or whole-home. - 2 ** ** ### Choose your setup Pick the configuration and alkaline enhancement that fits your household. - 3 ** ** ### Installation and walkthrough Most under-sink installs are completed in about an hour, with a full explanation of your new faucet and filter schedule. - 4 ## How your options actually compare We size the system to your actual test results, not a generic assumption about your water. ## Tested, not assumed, before we install anything We do not sell a fixed RO package off a shelf. Your free test tells us what your drinking water actually needs, and we configure the system, and the alkaline stage, around that. Every system comes with a clear filter schedule and warranty documentation, so you know exactly what is covered and when to expect service. - [See our warranty coverage](https://luciawatersolution.com/warranty) ## What buyers actually ask Still not sure what applies to your home?

We will be honest with you about what a given setup can and cannot address for your address. ### What is alkaline water and do I need it? #### 03 Alkaline water has a higher pH and added minerals compared to standard reverse osmosis output, which many homeowners prefer for taste. Whether you need it comes down to personal preference, not a health requirement. ### How often do reverse osmosis filters need to be changed? #### 04 Most filters need changing every 6 to 12 months depending on your household's water use, and we will give you a schedule specific to your system. ### Can I install reverse osmosis with well water? #### 05 Yes. Well water often benefits from additional pre-filtration ahead of the RO membrane, which your test results will help us determine. ## Explore related services - [Free water testing](https://luciawatersolution.com/services/free-water-testing) - [Whole house water purification](https://luciawatersolution.com/services/whole-house-water-purification) - [Water softener installation](https://luciawatersolution.com/services/water-softener-installation) - [System maintenance & repair](https://luciawatersolution.com/services/system-maintenance-repair) - [Commercial water treatment](https://luciawatersolution.com/services/commercial-water-treatment) - [Service areas](https://luciawatersolution.com/service-areas) ## Find out what your drinking water needs Book your free water test and get a reverse osmosis and alkaline system built around your actual results. - [Book Your Free Water Test](https://luciawatersolution.com/free-water-test) - Free in-home water test - Under-sink or whole-home options - Bilingual service - Financing available [Lucia Water Solutions](https://luciawatersolution.com) · [Privacy Policy](https://luciawatersolution.com/privacy-policy) · [Terms and Conditions](https://luciawatersolution.com/terms) · Powered by [Launch Automation](https://launchautomation.ai/custom)
