Reverse Osmosis in San Ysidro, CA.
Reverse Osmosis for San Ysidro homes, done by licensed San Diego County technicians. Reverse osmosis forces water through a semi-permeable membrane that rejects dissolved contaminants: dissolved solids, nitrates, heavy metals, PFAS compounds, sodium, and more. The result is water that consistently outperforms bottled water in purity and does it for pennies per gallon rather than dollars.
What reverse osmosis looks like in San Ysidro
San Ysidro tap water is safe by EPA standards but the chloramine chemistry and dissolved mineral content give it a flat or slightly chemical taste that most households prefer to filter before drinking. An under-sink reverse osmosis system at the kitchen tap reduces total dissolved solids to the bottled-water range, removes chloramines and disinfection byproducts, and filters nitrates from the Colorado River source water. We offer flexible financing on RO installations for San Ysidro families looking to eliminate the ongoing expense of bottled water.

How does San Ysidro's climate affect this service?
San Ysidro is southernmost San Diego on municipal water, with the same hard chloramine-treated supply as the rest of the city. Border proximity and the blended source water create awareness of water quality here, and point-of-use RO systems are a practical first step for households on a budget. San Ysidro tap water is safe by EPA standards but the chloramine chemistry and dissolved mineral content give it a flat or slightly chemical taste that most households prefer to filter before drinking.
Does reverse osmosis remove PFAS?
Yes. Reverse osmosis is one of the most effective technologies for PFAS reduction. The EPA established enforceable drinking water limits for several PFAS compounds in 2024, and NSF/ANSI 58 certified RO membranes are rated for PFAS reduction. We specify certified membranes on every RO install.
Does RO remove beneficial minerals?
RO removes most dissolved minerals, including calcium and magnesium. Some people prefer to add a remineralization stage after the membrane that reintroduces trace minerals and slightly raises the pH. We offer this as an add-on. For most households the difference in mineral intake from water versus food is negligible.
