Buying Guide: Filters for Renters

Keep these points in mind before you buy.

No plumbing needed

Countertop RO units plug in, faucet filters screw on without tools and dispensers sit in the fridge, so nothing changes your lease.

Gravity, RO, faucet or pitcher

Gravity systems need no power, countertop reverse osmosis plugs in, faucet filters work on tap, and pitchers and dispensers are the simplest.

Test before you buy

CDC says to test your water or review your utility’s annual water quality report, then choose a filter for what is actually in it.

Renter Water Tips

Clean water in a rental:

• Ask for the building’s water report.
