The standard coffee K-cup is essentially an invitation for microplastics to enter the body. A thin plastic shell that gets pumped full of boiling water and dripped into your coffee cup. Doing this occasionally is one thing, but add it up over months or years of daily coffee, and it becomes a real concern. This product is an obvious solution: a stainless steel, reusable K-cup with a dual-mesh filter, refillable with any ground coffee, compatible with Keurig 1.0 machines. The filter holds the grounds without letting sediment throug, without any plastic. This 2-pack is made in China, unfortunately no domestic equivalent exists.
