Our take
Set it and forget it
This is the stuff our customers ask us most, after 20+ years and [thousands] of systems sold.
The hardest part of filter changes isn't the swap. It's remembering. That's why our filters ship on a subscription: they show up when they're due, with the guide for that filter.
Write the install date on each housing with a marker. It takes two seconds and saves guessing later.
