Know the last change
Keep the completion date and history in one place instead of writing a date on the filter and hoping you remember to check it.
HVAC filter reminder for Android
Never wonder when you changed the filter.
Record the day you replace it, see when it is due again, and keep overdue filters visible until the work is actually done.

No calendar drift
The next reminder starts when the new filter goes in.
A fixed calendar repeats whether you changed the filter or not. Maintenance records the replacement you completed and starts the next interval from that real date.
Keep overdue visible
The filter stays on the due or overdue board until you actually mark the replacement complete.
Reset from the real date
Change it late and the next interval begins that day—not from the calendar date you missed.
Three small steps
Set your filter once. Reset it with one tap.
Maintenance does not force a generic schedule. Choose the interval that fits your filter and your home.

Your interval, not ours
One schedule does not fit every home.
Pick a starting interval using the guidance for your filter and HVAC system, then adjust it when your real conditions call for it.
Pets and household activity
More hair, dander, dust, or people can mean checking the filter sooner.
Allergies and air quality
Your comfort needs and local air conditions may affect the interval you choose.
System usage
Heavy heating or cooling seasons can load a filter faster than quiet months.
Filter type and thickness
Different filters have different guidance, so use the interval recommended for yours.
Maintenance is a tracking tool, not an HVAC diagnostic service. Follow your filter manufacturer or qualified HVAC professional for replacement guidance.

Filter reminder FAQ
How often should I change my HVAC filter?
There is no universal interval. Filter type, system usage, pets, allergies, and local conditions can all matter. Use the guidance supplied with your filter or HVAC system, then track that interval in Maintenance.
Can I track more than one filter?
Yes. Add separate intervals for multiple HVAC returns, furnace filters, water filters, air purifiers, or any other recurring item.
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.
