Stage 1 and 3 RO Filter Replacement

Regular price $64.99


The THD-RO3-R consists of Carbon (Stage 1) and Claryum (Stage 3) filter cartridge replacements for the THD-RO-3 OptimH2O Reverse Osmosis Drinking Water System. Aquasana OptimH2O delivers the best drinking water available for optimal hydration. It is the first system of its kind to pair powerful reverse osmosis filtration with Claryum selective filtration PLUS re-mineralization. Removes the most contaminants from your water while maintaining the benefits of healthy minerals that other reverse osmosis systems simply remove. Reverse Osmosis is the only proven water filtration method on the market to effectively remove fluoride from regular tap water. Aquasana's filter removes over 95% of fluoride for optimally healthy, clean water. The OptimH2O also re-mineralizes water to put back the healthy minerals lost in the reverse osmosis process like calcium, magnesium, and potassium for optimally alkaline, pH balanced water.
