How often should you change a whole-house water filter?
Every 6 months (twice a year).
Only some homes need this one. It is optional on the checklist and starts switched off in the tracker.
How to do it
Shut off the water, relieve the pressure, and swap the cartridge in the filter housing. Check the O-ring as you close it.
Why it matters
A spent filter stops filtering and slows water pressure through the whole house.
Recommended interval: every 6 months, per 3M Aqua-Pure / Solventum.
General guidance for a typical home; the manufacturer's instructions come first.
