AO Smith water purifiers are renowned for their advanced 8-stage purification systems, double-protection RO+SCMT (Silver Charged Membrane Technology), and MIN-TECH mineral replenishing cartridges. Here is how to keep your AO Smith purifier running in peak condition.
1. SC-TECH & Dual Membrane Protection
AO Smith purifiers utilize a secondary Silver Charged Membrane Technology (SCMT) stage following the primary RO membrane to prevent microbial re-contamination in the holding tank.
In neighborhoods with high hardness like Whitefield and Mahadevapura, seasonal sediment flushes protect this delicate dual-stage filtration array.
2. MIN-TECH (Mineralizer Technology) Calibration
The MIN-TECH cartridge restores essential alkaline minerals including calcium and magnesium, ensuring output water pH stays neutral to slightly alkaline (pH 7.2–7.8). We recommend replacing this cartridge every 12 months.
