What does a reverse osmosis system remove from drinking water?

Reverse osmosis removes 95-99% of total dissolved solids including lead, arsenic, fluoride, nitrates, PFAS/PFOS, chlorine, chloramines, sodium, and hundreds of other contaminants. The membrane has pores of 0.0001 microns, smaller than most water contaminants and even some viruses.

How often do reverse osmosis filters need to be replaced?

Pre-filters and post-filters in an RO system typically need replacement every 6-12 months. The RO membrane itself lasts 2-5 years depending on water quality and usage. Pure Agua offers annual maintenance plans to keep your system performing at peak efficiency.

Is reverse osmosis water safe to drink daily?

Yes. Reverse osmosis water is safe and recommended by many health professionals. The WHO notes that demineralized water lacks minerals, but these are easily obtained through a balanced diet. Many RO systems include a remineralization stage that adds beneficial calcium and magnesium back to the purified water.
