Many (most) tea bags contain pesticides and plastic which leeches harmful toxins into our teas which is not good for our bodies or the environment. These filters on the other hand are durable organic cotton and will last a year or more and can simply be composted after their time is up. I encourage you to switch to something simpler and slower. Purchasing loose-leaf tea and using a reusable tea bag creates less waste and doesn’t release microplastics into our bodies. Switching to a plastic-free, waste-free, more sustainable way of tea making is important for our health and environment! These filters are made with Certified Organic Cotton. Cotton imparts no flavor on the finished brew unlike paper. These filters are made in Austin, Texas and are sewn and packaged by happy human beings making a fair and living wage.
