Water filter replacement reminder for Android
Remember when you changed the water filter.
Record the day you replace each filter, see what is due next, and keep overdue replacements visible until they are really done.

No calendar drift
The next reminder starts when the new filter goes in.
A fixed calendar repeats whether you replaced the filter or not. Maintenance records the replacement you completed and starts the next interval from that real date.
Keep overdue visible
A filter stays on the due or overdue board until you actually mark the replacement complete.
Restart from the real date
Replace it late and the next interval begins that day—not from the calendar date you missed.
Three small steps
Set each filter once. Reset it when you replace it.
Maintenance does not force a generic schedule. Choose the interval recommended for your filter or appliance.
- 01
Add the water filter
Name it by location or appliance so every filter stays distinct.
- 02
Choose its replacement interval
Use the guidance supplied with your filter, system, or appliance.
- 03
Tap “Maintained now” after replacement
The change is logged and the next interval begins immediately.
One app, every filter
Track each water filter on its own schedule.
Add only the filters you use. Each one can have its own name, replacement date, interval, and completion history.
Refrigerator filters
Track the filter inside your fridge separately from every other replacement around the home.
Under-sink and reverse osmosis
Give each cartridge or system its own name and manufacturer-recommended interval.
Pitchers and countertop filters
Keep shorter replacement cycles visible without adding more repeating calendar events.
Whole-home filters
Remember the filters protecting the whole water system, even when they are out of sight.
Maintenance is a tracking tool, not a water-quality or filtration diagnostic service. Follow your filter or appliance manufacturer for replacement and safety guidance.

Water filter reminder FAQ
How often should I replace my water filter?
There is no universal interval. Filter type, model, water use, and manufacturer guidance can all matter. Use the instructions supplied with your filter or appliance, then track that interval in Maintenance.
Can I track more than one water filter?
Yes. Add separate intervals for refrigerator, pitcher, under-sink, reverse-osmosis, whole-home, or other filters.
What happens if I replace a filter late?
Mark it maintained on the day you actually replace it. The completion is added to history and the next interval starts from that date.
Does the app work without an account?
Personal intervals work locally and offline. Cloud sync and a shared Home are optional.
Start with one filter
Know when it was changed. Know what comes next.
Add the filter you do not want to forget, choose its interval, and let Maintenance keep the timing visible.
