Brita BritaPlus High Density Water Filter Replacement 2 Pack 8 Count Total OB08 Lot of two 4-packs (8 filters total) of BritaPlus High-Density Replacement Water Filters. These BPA-free filters are designed to trap 2X more contaminants compared to standard Brita filters, reducing chlorine, mercury, copper, and cadmium for better-tasting water. Each filter lasts for approximately 2 months or 40 gallons, meaning this lot provides up to 16 months of filtration. These high-density filters fit in all Brita systems except for the Stream series. The boxes are unopened and factory sealed, though they show external shelf wear including creases, small rips, and dings that do not affect the product inside.
