The dual-function AquaTru Carafe Pre-Filter (Filter #1-2) will last six months or 300 gallons, whichever comes first. This filter can only be used in AquaTru Carafe countertop purifiers.

The Pre/Carbon Filter reduces sand, silt, sediment, rust and particles from water. Activated carbon reduces chlorine taste and odors and conditions the water before it is treated by the reverse osmosis membrane.
