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.

Get reminded when it is due

Paper works until it goes on the fridge and stays there. The Househand app keeps the same checklist and tells you when each job comes due, based on when you last did it.

  • A reminder when a job is due, not on a fixed date
  • A history of what you did and when
  • The same schedule as this site, optional tasks and all

The app is not in the stores yet. Until it is, track your house in the browser: same schedule, same rules.
