A water filter improves the taste and safety of your drinking water by reducing chlorine, lead, sediment and other contaminants, whether through a simple pitcher or a whole under-sink system. The difference between a great filter and a basic one comes down to how much it actually removes, how much water it handles, and the ongoing cost of replacement cartridges. The picks below earned their tiers on real filtration performance, capacity, running cost and convenience.
The right water filter depends on what is in your water and how much hassle you will accept, so the choice runs from simple pitchers to under-sink systems. A pitcher filter like Brita is cheap, needs no installation and improves taste, which is enough for most people on decent municipal water. A more thorough pitcher like ZeroWater or a faucet mount removes more, while an under-sink reverse-osmosis system like APEC removes the widest range of contaminants for the purest water, at the cost of installation and price. If you are concerned about specific contaminants like lead, check that the filter is certified to reduce them, and always factor in the ongoing cost and lifespan of replacement cartridges, which adds up over time.

Some do, but not all. If you are concerned about lead, choose a filter independently certified to reduce it, such as certain pitcher cartridges, faucet mounts or reverse-osmosis systems. Always check the specific certification.
A pitcher filter is cheap and needs no installation, suiting most households on decent municipal water. An under-sink reverse-osmosis system removes the widest range of contaminants for the purest water but needs installation and costs more.
Pitcher filters like Brita are cheap and need no installation, improving taste for most households. Faucet mounts filter on demand from the tap. Under-sink reverse-osmosis systems like APEC remove the widest range of contaminants for the purest water but need installation. Choose based on how thorough you need to be and whether you can install.
Filters vary widely in what they remove, from basic chlorine and taste to lead, dissolved solids and more. If you are worried about specific contaminants, check independent certifications confirming the filter reduces them. A thorough filter like ZeroWater or reverse osmosis removes far more than a standard pitcher cartridge.
Consider how much filtered water you use and the lifespan and price of replacement cartridges, since this ongoing cost often exceeds the filter itself. Thorough filters exhaust faster and cost more to run. Balance upfront price, filtration level and long-term cartridge cost to match your household.
