• We recommend replacing Stage 2 (RO Membrane) every 2 years depending on usage and water quality. For homes with higher water usage and/or poorer water quality, you may need to replace your RO membrane every 1 to 2 years. For homes with lower water usage and/or better water quality, you may only need to replace your RO membrane every 2 to 3 years.
• We recommend replacing the remineralizer every 1 year depending on usage and water quality.
TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. Read more about TDS here.
Aquasana OptimH2O® Reverse Osmosis + Claryum® comes standard with a 12-month remineralizer designed to replace healthy calcium, magnesium, and potassium lost in the reverse osmosis process.
