Water Filtration

Water quality is coffee quality

Coffee is 98% water, which means the quality of your coffee depends on the quality of your water. Here's how to keep both in great shape.

Protect your water, protect your product.

We set up all Starbucks brewing equipment with a water filtration system at no charge, then you assume the responsibility of ordering and changing filters regularly. Water filters are only effective for a certain length of time, so they must be changed periodically. To help create a more user-friendly coffee program and to reinforce the importance of changing water filters regularly, we have made the process easier for you with one-stop shopping through our National Service Provider, Ecolab Equipment Care.

How often should your water filter be changed?

Filter life is determined based on two factors:

  • The volume of water that passes through the filter
  • The condition of the water mainly the hardness and sediment content

Although it is easier to replace filters on a calendar schedule, filter life can be determined only by evaluating these two factors. Starbucks will work with you to create an estimate for filter change frequency although we cannot provide accurate estimates in every case.

  • Water condition, content or quality can greatly impact your filter change frequency. For example, if there are high levels of sediment and/or particles in your water, you will have to change your filters more frequently than if you have little to no sediment. Be sure to replace your filters whenever you notice bad taste or odors or a drop in the flow rate. (Reduced flow rate will cause “short potting” [reduced amounts of coffee] and/or over-extracted and bitter coffee).
  • All brewers will be equipped with a water filtration system based on the water hardness and volume of water that passes through your brewer.
  • In average conditions, with average water consumption, your filter should last 6–12 months. This will vary in extreme cases (hardness greater than 20 Grains Per Gallon (GPG)), and a more robust filtration system combined with a softening system and/or pre-filter may be required.
Frequently Asked Questions:
  1. When would a more robust water filter system than what was originally supplied by Starbucks be required?
    • If the Grains Per Gallon (GPG) is higher than 20, additional water treatment or more frequent changes may be required.
  2. What water filter do I order?
    • For airpot brewers, order the In-Line Filter Cartridge ( IN-15CFS), part number EV9100-77KIT when the hardness is 3 or below. If the grains of hardness are over 3 use the Everpure 4FC5-S cartridge filter with Everpure QL3b head.
    • For 1.5, 3, 6 gallon single and twin brewers, hot water towers, and iced tea machines, order the 4FC5-S or 7FC5-S that fit in the QL3B filter head.
