Unlike an AC or washing machine, an RO purifier's parts wear out on a fairly predictable schedule — mainly because they're constantly filtering incoming water quality, which varies a lot depending on your source and area in Moradabad.
Sediment & pre-filters: every 3-4 months
These catch the first, heaviest layer of dirt and rust from the water supply. In areas of Moradabad with harder or more turbid water, this can need attention even sooner.
RO membrane: every 12-18 months
This is the core filtering component. A worn-out membrane doesn't just reduce output — it can let more dissolved impurities through without you noticing, since the water still looks and tastes normal.
UV lamp: every 12 months
If your purifier has UV disinfection, the lamp's germicidal effectiveness drops over time even if it still lights up. It needs yearly replacement regardless of how much water has passed through.
Signs you shouldn't ignore
Slow water flow, a change in taste, or the purifier running much longer than usual to fill a glass are all signs it's overdue for a service — don't wait for a full breakdown.
A Seerua technician in Moradabad can check all of this in a single visit and only replace what's actually needed — transparent pricing, no unnecessary upsells.
