A pour-over coffee maker made entirely of glass has been tested and reviewed, with reports highlighting its lack of plastic, toxins, and filters. The coffee maker is being considered among the best non-toxic and plastic-free options available, although it is unclear how it compares to other types of coffee makers, such as drip machines. The glass pour-over is also being noted for its potential to reduce microplastics in coffee and its relatively low cost compared to other brands.
