Basic Info About RO Membrane

Let’s first understand some basics of the Reverse Osmosis membrane.

Household RO systems have generally 75 gpd or 80 gpd capacity membrane. gpd means gallons per day. This indicates the capacity of Reverse Osmosis membrane to purify water in a day.

1 gpd (gallons per day) = 3.79 liters per day

For example,

  • 75 gpd membrane purifies 75 gallons of water per day or 284 liters of water per day.
  • 80 gpd membrane purifies 80 gallons of water per day or 303 liters of water per day.

Frequently Asked Questions

When to Change Reverse Osmosis Membrane?

We recommend change reverse osmosis membrane every three years.
If pre-filter is working properly & TDS level of water is as per membrane specification then membrane will lasts up to 3 years.

How to increase the life of the Reverse Osmosis Membrane?

You can do three things to increase life of Reverse Osmosis membrane:
1. Change pre-filters on a regular interval. Make a schedule to change the filters.
2. Only purify the required quantity of water. Don’t waste pure water.
3. Make sure input water TDS is as per membrane specification. Check the input water TDS

How to check Reverse Osmosis membrane is damaged?

Life of reverse osmosis membrane depends on four things:
1. Types of impurities present in input raw water
2. TDS level of input water
3. Healthiness of pre-filters
4. How much quantity of water you purified per day

Check the TDS of RO Purified water. If it is not reduced to the desired level or increasing trend then definitely your Reverse Osmosis membrane is damaged. You will need a TDS meter to test.

In some cases input raw water has very high TDS then also it will reduce the life of the membrane.

For example, your membrane is capable to handle 2000 ppm TDS & your feed water has 2500 TDS. In this case, your membrane life is reduced.

We recommend changing RO membrane every 3 years.


Out of all of these five, we like Filmtech RO Membrane which meets  NSF/ANSI Standard & gives excellent performance.
