With an array of ultra-fine etched holes, the Strong Brew Metal Filter will retain all of the natural oils of the coffee at the same time producing different flavour profiles for a full body flavour. These plastic free coffee filters are reusable and can be washed to use time and time again. Ideal for those who prefer their coffee with greater body, a velvety texture and want a reusable option. Diameter: 61mm Please note: the fine filter leads to a higher pressure in the brewing chamber so you should follow a slower plunge when brewing. Always ensure you do not overfill the chamber when brewing. For those who enjoy a clean coffee with zero grounds, FSC certified paper filters are also available.
