Abstract
Water treatment apparatus includes a housing, and at least one canister disposed within the housing. Inside the canister are disposed a first water treatment material and a second water treatment material, the first material being different from the second material. Both the first material and the second material acting alone makes the contaminated water more suitable for human consumption. Preferably, the first material is disposed in a first stage, the second material is disposed in a second stage which is physically discrete from the first stage. Alternatively, the first material and the second material may be admixed together in the canister. The apparatus preferably includes an alarm for indicating when the material for treating the contaminated water needs to be replaced.
