Best Water Filter: 5 Filters Compared by Spec

The listing states a BPA-free 10-cup pitcher with 1 filter, an easy-fill locking lid, WQA and NSF/ANSI certification, and reduction of chlorine taste and odor, mercury, copper, zinc and cadmium. It holds enough water to fill 3 24-ounce reusable bottles, and the listing notes that switching to Brita replaces single-use plastic bottles. The Longlast filter lasts 120 gallons or about 6 months, the Standard filter 40 gallons or about 2 months. The spec table gives 10.7 by 5.4 by 10.1 inches, which disagrees with the 10.47 by 5.59 by 10.94 inches in the bullets; the bullets are the figures to trust here.

Who it's for: households that want a full-size pitcher for the fridge shelf. Who should skip it: dorm rooms and mini-fridges, where the 6-cup pitcher fits better.

The listing states a 3-pack of Brita-compatible pitcher filters made in Europe, with a carbon filter, charcoal and fine mesh, WQA certification against NSF 42, 53, 401 and 372, and reduction of 9 contaminants including chlorine taste and odor, zinc, copper, cadmium, mercury, benzene, atenolol, linuron and trimethoprim. Each filter lasts 40 gallons or 2 months and each cartridge replaces 300 single-use water bottles. The title says 3-pack, but the spec table lists the size as 3 Count (Pack of 1) with 1 item, so the pack count is unclear; the title is the figure to trust here.

Who it's for: Brita pitcher owners who want backup cartridges for the household. Who should skip it: Brita Stream owners, since the listing excludes that model.
