PlanetCare Microfibre Filter

A filter for the washing machines to capture microfibres before being discharged into sewage and oceans

June 2023
Gallery PlanetCare Microfibre Filter 1
Gallery PlanetCare Microfibre Filter 1


We regularly ingest & inhale microfibres - tiny plastic fibres that our clothes, carpets, blankets etc. shed during use. By washing our clothes, we are releasing about one plastic bag worth of microfibres into the environment every week. Microfibres from washing are a major contributor to microplastic pollution. Microfibers in the environment enter the food chain and end up back on our plates. Attracting dirt, toxins and pathogenic bacteria they cause poisoning, genetic disruption (also in marine life!) and through the food chain affect humans. We eat 5g of microplastics every week, it is as if we ate a credit card. Our solution is a filter that attaches to the washing machine and captures microfibres before they enter the drain. The solution improves the quality of our waters by preventing the microfibres from being discharged into sewage and oceans and thus entering our environment. The dirty cartridges are being cleaned and reused and the mash caught recycled.
