Do water filter pitchers actually remove lead?

Only some do. Standard Brita and basic Waterdrop filters are certified mainly for chlorine taste and odor plus some heavy metals like zinc, copper and mercury. To target lead and microplastics you need a model with an upgraded filter, such as the Brita Elite, BritaPlus, or a specialist pitcher like Clearly Filtered. Always check the specific NSF/ANSI claims on the listing, because performance varies by filter cartridge, not just brand.
