Water purifiers are the gatekeepers of our health at home. Among them, Reverse Osmosis (RO) water purifiers are the most common. They ensure we get the cleanest water to drink, that is free from impurities and harmful microorganisms. However, over time, an RO purifier can also experience a dip in efficiency due to accumulated impurities as well as usual wear and tear. Here are some tips on how to maintain your RO water purifier so that it can perform optimally for longer.

Regular filter replacement

Every RO purifier needs its filters changed periodically. This is because of how the system works by pushing water through a semi-permeable membrane while holding back impurities. Over time, these impurities accumulate on the surface of the filter, decreasing its efficiency.



Use a softener if needed

The presence of magnesium and calcium in water can make the water hard. This makes it difficult for the filter in the RO Purifier to catch all the impurities alone. In this case, using a softener helps filter out some mineral impurities earlier to maintain the RO filter’s efficiency.



Place it correctly

The placement of your RO purifier is crucial. While the wall-mount placement is commonly seen in India, the under-counter placement is also used, especially in kitchens with a modular design. In high-moisture areas this can lead to sedimentation on the filter’s body and growth of bacteria. Ensure periodic cleanups to keep it safe.



Clean the exterior

Many of us only focus on the interiors of the purifier and don’t clean the exterior. This can lead to deposits of impurities and microorganisms building up near inlets and gaps in the system. Ensure regular cleanups of the purifier as well as the source, drain and the pipes leading to both.



Maintain adequate pressure

RO systems work because of the applied water pressure on the semi-permeable membrane. If the pressure drops, the efficiency on the system will fall too. Periodically check the water pressure at the source and maintain it atleast at the minimum level required for the RO system to perform optimally.
