Charcoal water filter-this is by far the easiest, cheapest and most zero waste water filtering option.

Adding a charcoal tube to your bottle's infuser will purify and mineralise tap water. It retains chlorine and releases calcium, potassium and other useful minerals. Bamboo charcoal has a reduced ecological impact compared to charcoal wood as it is faster growing, stores 5 times more carbon and absorbs impurities.

Stop buying plastic water bottles these leech not only microplastics, but also chemicals into your drinking water. A stainless steel bottle with a lid designed so that no plastic comes in contact with your drink is ideal. Charcoal filters will help remove any toxins from your tap water.
