9 Best Affordable Water Filters 2026

The Brita Metro steps in as a no-frills, budget-savvy champion for those just dipping their toes into filtered water. With its SmartLight indicator, this compact pitcher takes the guesswork out of filter replacement—flashing yellow at 40 gallons and red when it’s time to swap. It’s equipped with a Standard filter that effectively cuts chlorine taste and odor while reducing copper, cadmium, and mercury, making it a solid choice for urban tap water plagued by chemical aftertastes. For renters or students needing a simple, spill-proof design with fridge-friendly dimensions, this pitcher hits the sweet spot between functionality and affordability.

In everyday use, the 6-cup capacity suits individuals or couples but falls short for larger households. The flow rate is moderate, taking about 10–15 minutes to filter a full pitcher, which can feel slow if you’re in a rush. It performs reliably on standard municipal water, though it struggles with hard water scaling over time. While the SmartLight system enhances convenience, it requires batteries and adds a slight learning curve. Users with well water or high sediment levels may find they need pre-filtration or more frequent changes, as the Standard filter isn’t designed for heavy-duty purification.

Compared to pricier pitchers like the Waterdrop models, the Brita Metro trades long filter life and advanced filtration for entry-level accessibility.
