The Brita Metro Water Filter Pitcher is a compact and easy-to-use water filtration solution designed for everyday home use. It holds 6 cups of water, which is a modest capacity ideal for individuals or small households rather than large families.

The filtration flow rate is gentle but sufficient for this pitcher size, allowing you to refill without long waits. Installation is straightforward since it’s a freestanding pitcher with no complex setup, and the BPA-free plastic design is safe and lightweight. A handy SmartLight indicator reminds you when it’s time to replace the filter, making maintenance simple. Filters typically last about two months or 40 gallons, which is standard but means you will need to keep purchasing replacements regularly.
