A reverse osmosis system uses water pressure and a semipermeable membrane to separate many dissolved substances from water. SimPure offers both countertop and under-sink RO systems with different capacities and filtration configurations.
RO technology can reduce many dissolved salts and contaminants, but actual reduction performance depends on the membrane, filter stages, feed-water conditions, and the specific product's tested performance. Check the specifications of the individual system when targeting a particular contaminant.
Yes. TDS reduction is one of the primary functions of an RO membrane. Final TDS levels vary with source-water TDS, membrane condition, water pressure, and system design.
Yes. RO membranes reduce many dissolved minerals along with other dissolved substances. Remineralization or alkaline RO systems add selected minerals back after RO treatment for users who prefer a more mineralized taste profile.
Properly treated RO water can be used as everyday drinking water when the system is correctly installed, maintained, and supplied with suitable source water. Filters and membranes should be replaced according to the system's maintenance requirements.
Yes. RO filtration separates incoming water into purified water and a concentrated reject-water stream. The amount of reject water varies by system design, membrane efficiency, pressure, and operating conditions.
Low-TDS RO systems focus on reducing dissolved substances through reverse osmosis. Alkaline or remineralization systems add selected minerals back after filtration, which can change the mineral content and taste of the finished water.
GPD means gallons per day and describes the system's rated production capacity under specified conditions. Higher-GPD systems are generally better suited to households that need faster water production or greater daily output.
