Roommates, Bills, and Who Owns the Filter

Roommates can share:

• Wi-Fi
• rent
• a toaster nobody cleans

…but a water filter? Suddenly it’s courtroom television.

“Who bought it?”
“Who changes the cartridge?”
“Is this coming with me when I move?”

Let’s avoid a filter custody battle.

The easiest “shared win”

Start with a pitcher filter or fridge filter because it’s:

• cheap
• simple
• obvious
• naturally “community property” if you agree on it

The roommate-proof plan

1) Pick one shared filter (pitcher or fridge)
2) Make a tiny monthly split for cartridges
3) Choose a “Filter Captain” (rotates monthly)
4) Label it so nobody “accidentally” claims it

If showers are the bigger issue, add a shower filter for the person who’s sensitive.

Quick path

• split it, set it, done.
• make it fun: taste test challenge.
• reduce daily friction.
• track cartridge dates + receipts.
