I write on my kitchen calendar to check and change filters
every 3 months. No problem keeping track of when to do
this.

And when to fertilize the citrus trees, when to change the batteries
in the smoke detectors, when the roof needs to be repainted, when
the swamp cooler pads need to be serviced, etc.

We find it easier to just put things in very regular schedules:
e.g., instead of fertilizing three times/year (as recommended),
we fertilize monthly; cooler gets serviced at end of season
with pads replaced (instead of waiting for the pads to *need*
to be replaced); smoke detector batteries on New Years Eve;
roof gets 20% serviced each year -- instead of once every 5
years; etc.
