Keep reading this article to know about the right and adequate time to change the purifier’s RO membrane to get safe and healthy drinking water.

Factors to consider for replacing RO membrane in RO Water Purifier

When it comes to changing the RO membrane, you have to look into several factors. Moreover, learning about these factors help you know the right time to change the membrane and filters.

  • The level of impurities in the input water.
  • TDS level in the water.
  • How much amount of water you purify with the RO purifier?

If the water contains a high level of impurities, high TDS level, and you need to purify a large amount of water, then you have to replace the RO membrane frequently.

Always go for branded purifiers under 15000 or 20000 range as the membrane comes in such a model tends to have a long life.

It is suggested to change the sediment filter, carbon filter, and DI cartridges regularly. The cartridge begins to exhaust, and it depends on the impurity level in the water supply and how much water you need to filter in the RO purifier.

The RO pre-filter should be replaced every 3 to 4 months. The replacement interval depends on the quality and quantity of water purified. 

Other filters like carbon filter and sediment filter should be replaced every 6 to 12 months. It also depends on the amount of water to purify and how good the quality of input water is. However, this is an average time to change, and for the exact time, you have to look at filters individually.

Furthermore, if there are any leakages or drips in the RO purifier, make sure to call a professional to fix it. If you neglect to fix it immediately, it will cause severe damages to the water purification system.

When to change the RO membrane in the RO water purifier?

The membrane is semi-permeable. RO membrane is a significant part of any RO purification system and is responsible for all the processes. Sediment and carbon filters are only preparing the water, so it does not repair often.

If you maintain the sediment and carbon filters well and replace them at regular intervals, you have to change the RO membrane after 4000 to 6000 liters of water purification. 

The schedule for replacing the RO membrane for a family size of 4 to 6 members is three to 4 months. RO membrane lasts longer as per the TDS input of water.

Additionally, the RO membrane will last for 2 to 3 years, and also experts say that even it lasts for five years. The RO membrane will get damaged if the water is hard and improper flushing of the membrane. The replacement will be done based on input water, the efficiency of sediment, and carbon filters.

The easiest way to check when you should replace the RO membrane is by using the TDS meter. The TDS meter is used to check the quality of purified water. It is recommended to buy a digital TDS meter to find the TDS in water easily.

You can find that the RO membrane will go wrong when there is a high range of TDS. Moreover, it is recommended to replace the RO membrane every 2 to 3 years when the TDS is low.

Why it is essential to maintain and replace the RO membrane?

Before moving into maintenance, you have to know about the membrane and filters’ functions and performance. The filter is the best defense system that separates the impurities from the water. 

The RO membrane has small-sized pores that allow only the water molecules to pass through and leave the microorganisms and harmful substances on the other side.

There are several reasons for maintaining the RO membrane in the water purifiers over a period. 

  • A good and useful RO water membrane in the purifier ensures fresh, clean, and safe drinking water for the family.
  • Maintenance of the RO membrane increases the life span of the purifier.
  • It will reduce the expenses for maintaining the RO purifier.
  • This will avoid unnecessary charges for technicians and services.

A final note

Merely buying the Best water purifier in India does not provide you the best form of drinking water. It is a duty to maintain the RO water purifier and its membrane for clean and healthy water. Added to it, you have to replace it regularly to enhance the life span of the purifier.
