This does not prove that zero microplastic or nanoplastic particles are present or could ever be released.
Microplastic Status
Based on available ingredient data, British Berkefeld Stainless Gravity Filter 8.5L does not contain known microplastic ingredients. Materials used include stainless steel upper and lower chambers, Ultra Sterasyl ceramic elements, black plastic wing nut, rubber sealing washer, gravity tap (material not stated). This assessment is based on publicly available product information and ingredient databases.
How we assess products
We work from published information; we do not lab-test, and a verdict here is never a claim that we have.
Low concern means the published materials we assessed show no known microplastic ingredient and no material microplastic concern. It does not mean:
- Not proof that no microplastic or nanoplastic particles are present or released — analytical methods have lower size limits, and nanoplastics largely escape detection.
- Not elimination of background exposure, which indoor dust and diet may dominate anyway.
- Not proven health safety — current science cannot substantiate that for any product.
- Not a general environmental or sustainability endorsement.
About This Product
Based on available material data, both chambers are stainless steel and the elements are ceramic with a granular carbon core, so filtered water stands in steel from the moment it leaves the candle. Two plastic parts remain: Doulton's own "black plastic wing nut" holding each element, and the standard tap, whose material Doulton does not state — a stainless steel tap is sold separately. Doulton claims a 99.9% microplastic reduction for the Ultra Sterasyl element, citing NSF/ANSI 401.
