A saturated filter does not announce itself, it just quietly stops filtering. The service schedule is the only real evidence your water is clean.

The standard RO service cycle.
The bigger internal parts, once a year.
A RO service reminder on WhatsApp takes one message and no setup: text NagMeLater what to remind you of and when, and it confirms within seconds and nags you at that exact time. For this topic the schedules people pick most are Every 6 months (the standard RO service cycle) and Yearly membrane check (the bigger internal parts, once a year); each button above sends the exact wording, for example "Remind me every year on 15 June to get the RO membrane checked", and you can change the time or the task before sending. Recurring works in the same sentence ("every Monday at 9am"), in any language you text in. When it fires, reply done to close it, snooze 15 to be nagged again, or edit 1 to Friday 5pm to move it. First 7 days free, then $1.99 a month or $59 once for life.
Water from an exhausted filter looks, and mostly tastes, identical. The degradation is invisible by design, which makes memory the only safeguard, and memory is busy.
Every 6 to 12 months depending on usage and water quality: too rare to be routine, too important to skip. Classic external-reminder territory.
The technician's marker scribble of the next service date is the entire tracking system for most homes. It was never going to survive a kitchen.
Sediment and carbon stages have finite capacity. Past it, they stop trapping and can even shed accumulated contaminants back into the water, on time beats on taste.
If your unit shows TDS, a creeping number between services means the membrane is tiring. Note the reading at each service ("note TDS was 62 after June service") and trends become obvious.
Annual maintenance contracts lapse quietly too. A yearly "renew or rethink the RO AMC" nag keeps you from paying for coverage that expired in March.
The button pre-fills it. Plain words, no format to learn, no reminder app to install.
Date, time and recurrence are parsed from your message and confirmed instantly.
Right inside WhatsApp, where you will actually see it. Reply done, snooze it, or edit it any time.
Their reminder system is a sales pipeline, yours is a health habit. Set your own nag and treat their call as a bonus.
Ask the technician at the next service and set precisely that: heavy usage and hard water shorten it, light usage stretches it.
Absolutely the same pattern: "every 6 months, book the AC service", "every 3 months, degrease the chimney filters". One nag each, kitchen sorted.
Monthly or bimonthly one-liner: "Remind me on the 1st of every month to change the water jug cartridge".
The one you will actually open. Dedicated reminder apps get installed, muted and forgotten; WhatsApp gets opened dozens of times a day. NagMeLater uses that: send "Remind me every 6 months to book the RO water filter service" once and the reminder comes to you, no separate app involved.
The button opens WhatsApp with "Remind me every 6 months to book the RO water filter service" already typed. Send it, and it is handled.
