Most filtration advice assumes you can cut a hole in a cabinet and tap into a supply line. Renters cannot. The good news is that the options which need no permission handle the most common complaint — chlorine taste — perfectly well.
What works without touching the plumbing
Filter pitchers
Zero installation, lowest cost, and they move with you. The trade-off is capacity: you are refilling a jug several times a day in a household of three or more, and cartridges need changing every month or two.
Faucet mounts
Screw onto the aerator thread of most standard kitchen taps and divert water through a cartridge on demand. No tools, no permanent change, and reversible in seconds when you move out. They do not fit pull-out sprayer taps or some designer fixtures — check your tap before buying.
Countertop units
Connect via a diverter at the tap and sit beside the sink. More capacity and longer cartridge life than a pitcher, at the cost of counter space. Still fully removable.
Pitcher
Cheapest start. Best for one to three people who mainly want better-tasting drinking water.
Faucet mount
Filters on demand, no counter space used. Check your tap thread first.
What to avoid as a renter
Under-sink systems need a hole drilled for the dedicated tap and a connection to the supply line. Whole-house systems are out of the question. Both are landlord conversations, and neither comes with you when you move.
Also worth knowing
If your building predates the mid-1970s, lead from the plumbing is a real possibility and it is not your landlord’s water quality report that answers it. Ask whether the service line has been replaced, and if you cannot get a straight answer, buy a filter certified to NSF/ANSI 53 for lead rather than one rated only for taste.
