Like any appliance, an RO filter requires regular maintenance to perform at its best. Ignoring filter replacement schedules can lead to reduced purification efficiency and even contaminate your drinking water over time.

One of the most common signs that your RO filter needs attention is a change in water taste or odor. If your purified water starts tasting metallic, sour, or simply "off," it's likely time to replace the carbon or sediment filters.

Reduced water flow is another red flag. As sediment filters clog with debris over months of use, water pressure through the system drops noticeably, slowing down your RO filter's output significantly.

You should also watch for unusually frequent draining sounds or the purifier running continuously without filling, which may indicate a failing membrane or float valve issue.

Most manufacturers recommend replacing sediment and carbon filters every 6 to 12 months, with the RO membrane lasting 2 to 3 years depending on usage. RO Megamart offers AMC plans that take the guesswork out of maintenance, ensuring your RO filter always performs optimally.
