Minus Water Filter

Sustainable Products, Projects and Green Design Minus Water Filter by Anastasia Klimova Minus is a portable tap water filter designed to be reusable and zero waste. Minus uses pressure from the tap to push water through a filter of activated coconut charcoal, removing chemicals, bacteria and odour. The body is made of stainless steel with a rubber coating for a better grip when wet. A natural indigo colourant inside the filter washes out gradually with use, showing clearly when a replacement is needed. The used filter can be posted back, then cleaned, recharged and reused, which avoids the waste left by disposable filters.
