The purest water in your home, right at the kitchen tap. A reverse osmosis system strips out PFAS, lead, arsenic, sodium, and the dissolved solids that affect taste, so every glass, pot of coffee, and ice cube is clean. It starts with a free in-home water test.
A local Massachusetts water specialist replies fast, usually the same day.
Reverse osmosis, or RO, pushes your water through a membrane so fine that it blocks the vast majority of dissolved contaminants while letting clean water through. Where a whole-house carbon filter handles chlorine, sediment, and taste for the entire home, an RO system goes further at one tap, usually the kitchen sink, to produce the purest drinking and cooking water you can get without hauling bottles.
For Massachusetts homes that is a meaningful upgrade. RO is one of the most effective ways to reduce PFAS, lead, and arsenic at the point of use, and it also pulls out the sodium that a water softener adds back in. We size and install the right system for your water and your space, and we base the recommendation on a free test rather than a sales pitch.
RO is among the most effective point-of-use methods for reducing the PFAS that Massachusetts regulates at 20 ppt. More on PFAS.
Older MA homes and service lines can leach lead. RO reduces it right at the tap you drink from.
If you soften your water, RO removes the sodium it adds, so your drinking water stays low-sodium.
RO reduces nitrates, excess fluoride, and other dissolved contaminants a carbon filter alone leaves behind.
Lowering TDS is what gives RO water that crisp, clean taste people notice immediately.
Most reverse osmosis systems in Massachusetts run between $350 and $1,200 installed, depending on the number of stages and whether you choose a standard tank or a high-flow tankless model. Here are the typical 2026 ranges. Your free water test tells us what makes sense, and you get one fixed price before we start.
| System | Typical installed range | Best for |
|---|---|---|
| Standard under-sink RO | $350–$650 | Great-tasting drinking water |
| High-capacity / tankless RO | $700–$1,200 | Faster flow, no bulky tank |
| RO + remineralization | $550–$1,000 | Adds back minerals for taste |
| Annual filter service | $90–$180 | Keeps it performing |
Ranges include standard installation at an existing sink. Adding a dedicated faucet, fridge line, or booster pump can affect the total. We quote one fixed price up front.
If bottled water is your habit, RO gives you the same quality on tap for a fraction of the ongoing cost.
RO is one of the most reliable point-of-use fixes for these specific contaminants.
RO removes the sodium softening adds, so your drinking water stays crisp and low-sodium.
High dissolved solids give water a flat or mineral taste. RO fixes it at the tap you use most.
RO is a strong final polish on top of a whole-house well system for the water you actually drink.
Clean, low-TDS water genuinely improves the taste of coffee, tea, and ice, and protects your machines.
We test your water and walk you through what is in it, so you know whether RO is worth it for your home.
We recommend a system sized to your water and your space, at one clear fixed price with no upsell.
Our team installs it under your sink (or where it fits best), adds the faucet, and leaves everything neat, usually in one visit.
RO filters need changing roughly once a year. We show you how, or handle it for you on a schedule.
Massachusetts has taken PFAS more seriously than most states, setting an enforceable limit of 20 parts per trillion for six PFAS compounds. Even so, that standard applies to public supplies as a whole, not the specific water reaching your kitchen tap through your home’s pipes, and it does nothing for the many households on private wells. For the water your family actually drinks, a point-of-use RO system is one of the most dependable safeguards you can add.
It also pairs naturally with the rest of your setup. Many of our customers run a whole-house filter or softener for the whole home and add RO at the kitchen for drinking and cooking. That combination handles chlorine, hardness, and sediment everywhere while giving you the purest possible water where it matters most. We will tell you honestly whether RO adds enough for your water to be worth it, based on your test, not a script.
“They were fantastic. Very responsive and came out the next day. Luiz was knowledgeable and efficient, and I did not feel upcharged. Much better than other companies after interviewing multiple. They were the best.”
“We stopped buying bottled water entirely. Sean explained our options, installed a clean under-sink system, and the water tastes incredible. No pressure at all.”
“Can’t thank Sean and his team enough. Incredibly kind, courteous, and professional while explaining every detail. Honest work from people who clearly care about doing it right.”
Most installed systems run about $350 to $650 for a standard under-sink RO, $700 to $1,200 for a high-capacity or tankless model, and $550 to $1,000 with remineralization. Annual filter service is roughly $90 to $180. Your free water test tells us what fits, and we quote one fixed price.
Yes, RO is one of the most effective point-of-use methods for reducing PFAS, along with lead and arsenic. We confirm your contaminants with a test first, then size the system to address them. See our PFAS treatment page.
They do different jobs. A whole-house filter handles chlorine, sediment, and taste for the entire home; RO gives you the purest possible water at one tap for drinking and cooking. Many homes use both.
It removes most dissolved minerals along with the contaminants. If you prefer mineral taste, we can add a remineralization stage that puts calcium and magnesium back after filtration.
Older systems sent several gallons to drain per gallon produced. Modern high-efficiency and tankless RO units we install are far more efficient, and we size the system to your usage.
Most commonly under the kitchen sink with a small dedicated faucet on top. If space is tight, we have compact and tankless options, and we can run a line to your fridge or ice maker.
Pre- and post-filters are usually annual, and the membrane lasts several years depending on your water. We show you how or handle service for you.
Yes, completely. We test your water in your home, explain the results plainly, and there is no obligation to buy anything.
The best way to know whether reverse osmosis is right for you is to see what’s in your water. We’ll test it in your home at no cost, explain the results plainly, and only recommend what your water needs. No pressure, no obligation.
