EAST VILLAGE — A new café recently opened up on East 10th Street — but don't expect to find customers sipping on lattes. 

Molecule, aka the Water Café, is filtering New York City tap water down to its purest form and serving it for $2.50 to thirsty local patrons using a custom-made device worth more than $20,000. 

"It's about treating water a little more consciously, mindfully and respectfully," said co-owner Adam Ruhf, 32, who has a background in music and activism. 

But the store is not only planning to peddle its gallons for in-home use, as passersby can stop in for a quick gulp — complete with an option to add vitamin supplements to their H2O cocktails. 

The store has been in the works for 18 months, with Ruhf taking the concept of self-service water shops in Los Angeles and building on the theme. 

"This is like a water store 2.0," he said of the opening, which was first reported on EV Grieve.
