Hard water leaves a chalky buildup inside your espresso machine, and that's the number one reason those machines break. It also throws off how your coffee tastes from one day to the next. This filter fixes both, for less than a penny a cup.
First in the cup, where the taste shifts a little every day and customers can tell something's off. Then in the back, where hard water slowly cakes up the inside of your most expensive machine.
That chalky buildup from hard water is the leading cause of espresso machine failure.
A full repair starts around $500. A new machine runs $3,000 to $15,000.
Water is almost the whole drink. When it changes, your coffee changes, and regulars notice.
Move the slider to how many drinks you make a day and see how small the unit cost gets per cup over five years.
At most shop volumes, the unit cost lands well under 1¢ per drink.
The unit is a one-time $1,299 before tax and shipping. Here's what that sits next to.
| Item | Cost |
|---|---|
| eSpring Under the Counter Unit with Aux Faucet (you pay once) | $1,299 |
| One service call to clear out buildup | $200 – $500 |
| Fixing an entry-level machine | $500+ |
| Replacing a machine that died | $3,000 – $15,000 |
It pays for itself on machine protection alone in the first year, before your coffee even tastes better.
