Quick Answer
Our top pick is Vontron 75 GPD RO Membrane — Universal Fit — The default recommendation for 75 GPD domestic RO membrane replacement in India.
The RO membrane is the heart of any RO purifier — it's the stage that actually removes dissolved salts and contaminants. Unlike pre and post-carbon cartridges, a failing membrane can't be detected by taste alone; you need a TDS meter to confirm. This guide covers the membrane-replacement decision specifically, across all major Indian domestic RO brands. Most Indian domestic units use a 75 GPD membrane (Kent Grand/Supreme, Aquaguard Magna/Enhance, Livpure, Havells, Blue Star); some premium units use 80 GPD (Kent Superb) or larger. Service life is typically 12–24 months depending on input TDS: high-TDS borewell cuts life to 10–14 months, low-TDS municipal supply stretches it to 24+ months. Honest red flag: you should only replace an RO membrane when TDS output has actually risen — not on a calendar schedule. Replacing a working membrane is pure waste. Buy a ₹200 TDS meter; it pays for itself in 6 months of avoided unnecessary changes.

Check Latest Price on Amazon →What to Look For
- 1.When to replace — the only right answer involves a TDS meter. Measure input TDS and output TDS monthly. When output TDS climbs above ~60 (for normal use) or above 30% of input, the membrane is degrading. Before that point, replacement is premature. The calendar-based "every 12 months" guidance is a service-shop revenue protector, not a real requirement.
- 2.GPD selection. Most domestic units need 75 GPD (check your unit manual). Oversizing to 80 GPD on a 75 GPD unit doesn't give more output — it's limited by the pump and housing. Undersizing (e.g. 50 GPD on a 75 GPD unit) strains the pump and cuts its life. Stick to the exact GPD rating.
- 3.OEM vs compatible. Vontron is the industry-standard compatible in India and performs within 5% of branded membranes on rejection rate. It's what many smaller brands relabel and sell as their own. For under-AMC units, stick with OEM. For out-of-AMC units, Vontron is a safe save-half-the-money choice.
- 4.Installation direction is the single most-failed DIY step. The membrane has an arrow or flow-indicator showing the direction of water flow — input side thick, output thin. Installing reverse causes a leaky seal and the TDS reading will go WRONG (higher than input, sometimes). Read the arrow. Verify twice before seating.
- 5.Housing pressure. After replacing the membrane, seat the housing hand-tight plus a gentle quarter-turn with the supplied wrench. Overtightening cracks the housing or pinches the O-ring — both cause bypass leaks. Undertightening lets water escape around the membrane — also causes high output TDS.
- 6.Post-install protocol. Flush 15–20 litres through the new membrane before drinking. The factory preservative (sodium metabisulphite) needs to wash out. Read TDS output after the flush; if it's in your expected range, you're good. If it's high, check install direction and housing seal before replacing the membrane again.
