If you don't have the Zero Water pitcher and filter, you have no idea how delicious water can taste. I will never give mine up. Filters last a long time and are about $11 each. Don't be shocked when the meter shows you how much dissolved solids are in your tap water. Meter reads 000 once the water is filtered. Unless you have a well (without iron or arsenic, etc) you need this. Added benefit: I drink a lot more water and little else.
