Though technically dishwasher safe, for the longest term product satisfaction, we recommend hand washing your MiiR in hot, soapy water with a long-handled soft bristle brush. Extremely high water temperatures and the rigorous environment of a dishwasher will deteriorate these finishes over time. All MiiR lids are easily hand washed and are also top rack dishwasher safe.
Package free; primarily compostable except very minor components (e.g. plastic toggles or small stickers)

About MiiR
MiiR was launched in 2010 and features products created with function and simplicity in mind, and with an end result to further improve lives and build community. Every product we design is built in-house with an emphasis on innovation, timelessness, simplicity and sustainability. We call ourselves a Product to Project™ company, which is our way of saying every purchase of a MiiR product supports a trackable giving project. We accomplish this by giving 3% of revenue to clean water and health projects around the world, and reporting back to our customers GPS coordinates, photos and achieved outcomes for total transparency. The meaning behind MiiR (pronounced “mEEr”) is twofold, both of which emphasize the worthy pursuit of making our world a better place to live, protect and enjoy. The first is a tribute to John Muir, a rugged mountaineer and protector and advocate of America’s treasured lands in the late 1800’s to early 1900’s. Considered the “Father of the National Parks” that we know and love today, Muir penned the beloved quote “the mountains are calling and I must go.” The second borrows from Eastern European languages; “mir” loosely translates to “world” or “peace,” serving as a reminder that each of us plays a role in achieving harmony on a global scale, including social and environmental efforts.
