Buying Guide: best water filter for an apartment

Installation Type

Consider whether you want an under sink filter, countertop unit, or water dispenser. Under sink filters require some plumbing but save counter space. Countertop and dispenser models need no installation but may take up space.

Filtration Performance

Look for filters certified to remove contaminants like chlorine, lead, PFAS, and heavy metals. Some systems add UV light or remineralization for balanced water quality.

Size and Space Constraints

Apartment kitchens often have limited space. Compact under sink filters or portable countertop units are ideal. Water dispensers fit well in fridges but require regular refilling.

Maintenance and Filter Life

Check how often filters need replacement and the cost. Longer filter life reduces maintenance frequency and overall cost. Some models include filter life monitors for convenience.

Balance upfront cost with long-term savings on bottled water and filter replacements. Higher-end systems offer advanced filtration but may cost more initially.
