Reverse osmosis drinking water on the Main Line
Clean, great-tasting water from its own faucet at your kitchen sink. Our under-sink reverse osmosis systems reduce PFAS, lead, nitrates, and dissolved solids for homes across the Main Line and Delaware County.
Why Main Line homes add reverse osmosis
Most Main Line homes are on public water that meets federal standards, but standards change and many families want more. PFAS, often called forever chemicals, have been found in public water systems across Southeastern Pennsylvania, and the EPA set new limits for them in 2024. Older homes can also pick up lead from plumbing after the water leaves the utility.
Reverse osmosis is one of the most effective ways to reduce PFAS, lead, and other dissolved contaminants at the tap you drink and cook from.
Tankless or tank
Tankless systems are compact, fit easily under the sink, and deliver water on demand. Tank systems store filtered water and suit homes with lower water pressure. We recommend the one that fits your kitchen and your water, and we can add a remineralization stage for better taste.

Common questions
Does reverse osmosis remove PFAS?
Reverse osmosis is one of the treatment methods the EPA identifies as effective for reducing PFAS. Results depend on the system and maintenance, which is why we install certified systems and keep up with filter changes.
Will it fit under my sink?
Almost always. Tankless systems in particular take very little cabinet space.
How often do filters need changing?
Typically every 6 to 12 months for prefilters and every few years for the membrane, depending on your water and use. Our care plans handle it.
Can I see my water report?
Yes. Our water reports section summarizes the latest public reports for every county we serve, including PFAS results.
