   So, it turns out that reverse osmosis filtering adds a metric shitload of *nano*plastics to the water because it leaches off the Polyamide filter.
   
   Third wave coffee shops *always* RO their water and then add calcium and magnesium back at specific levels to ensure optimal flavor (through improved extraction). Plus this shields their espresso machines from damage of mineral buildup.
   
   So your latte comes with a side of nanoplastics. Enjoy!
   
   (at least the microplastics are filtered out, right?)
