RO Membrane Replacement in Bangalore
The membrane is the part that actually purifies your water, and when it needs replacing early, the more useful question is why the last one died.

How to know the membrane has gone, and why it went early
The RO membrane is what separates a water purifier from a water filter. It removes dissolved solids -- salts, hardness, heavy metals -- that no cartridge filter can touch. It is also the most expensive consumable in the system, which makes both the diagnosis and the cause worth getting right.
Diagnosis is a number, not an opinion. A membrane is tested by measuring TDS at the inlet and at the purified outlet. A healthy domestic membrane should be removing the large majority of dissolved solids. If your input water is high and your output is close behind it, the membrane is no longer doing its job. This is a measurement anyone servicing your unit should be able to show you on a meter -- if the recommendation to replace comes without a TDS reading, ask for one.
Symptoms before the test. Water that has started tasting salty or hard again, scale reappearing in your kettle, or a noticeable drop in purified output while reject water continues normally. Any of these are worth a TDS check.
Why membranes die early. A membrane should give a couple of years or more. When one fails in months, there is almost always a cause worth fixing, or you will simply buy another one. Chlorine damage from an exhausted pre-carbon filter is the leading cause and is permanent. Sediment fouling from a neglected pre-filter physically blocks the membrane surface. Scaling from very hard input water shortens life. And running the system at incorrect pressure, or with the reject ratio set wrong so it does not flush properly, accelerates fouling.
Getting the specification right. Membranes are rated by GPD -- gallons per day -- and fitting a rating that does not match the pump and system produces poor flow or excessive reject water. The correct part matters more here than on the cartridge filters.
Reject water. RO inherently produces waste water alongside purified water. If yours has changed noticeably, that is diagnostic information. A system producing almost no reject is not flushing the membrane properly and will foul it quickly.

RO Membrane Replacement in Bangalore — frequently asked questions.
How do I know the RO membrane needs replacing?
By measuring TDS at the inlet and the purified outlet. If the output figure is close to the input, the membrane is no longer removing dissolved solids. Anyone recommending replacement should be able to show you those readings on a meter.
How long should an RO membrane last?
A couple of years or more, provided the filters ahead of it are maintained. If yours has failed within months, there is almost certainly an underlying cause that needs fixing or the replacement will fail the same way.
What kills RO membranes early?
Chlorine damage from an exhausted pre-carbon filter is the leading cause and it is permanent. Sediment fouling from a neglected pre-filter, scaling from very hard input water, and incorrect reject ratios are the others.
My purifier wastes a lot of water. Is that a fault?
Some reject water is inherent to how RO works and is necessary to flush the membrane. A system producing almost no reject water is actually the concerning one, because it is not flushing properly and will foul quickly.
Does the membrane rating matter?
Yes. Membranes are rated in GPD and must match the pump and system. Fitting the wrong rating produces poor flow or excessive waste water, so the correct specification matters more here than it does on the cartridge filters.
