Glass filter with laser drilled holes, from Trendglas. For use with: Trendglass glass teapots models: Theo, Nova 1200ml, For Two, Soma teapots, Opus, Puck, Zyclo cup, Office cup 400ml and Office cup 600ml. This strainer can also be used on the Glass Kettle and Pour Over Glass Kettle thus turning it into a teapot. Unlike the large Trendglas filter with slots located at the bottom of the filter, this new filter has small, fine laser- drilled holes distributed along the wall and base. This improved design optimizes the infusion, in such a way that fewer leaves are needed and, in turn, a drink without impurities is obtained. The filter is made of borosilicate glass: a non-porous material, neutral in terms of taste and smell, which does not react in contact with any substance and has high thermal resistance. It is also the most non-toxic material that exists and therefore totally safe in terms of the absence of transmission of substances, in addition to being heat resistant. It is the glass that is used in laboratory material and is the most recommended option for people with allergies or sensitivities, or for people who appreciate the maximum purity in materials.
