If you’re not lucky enough to live in a city with great-tasting, safe-to-drink tap water, you probably go through your share of plastic water filters. But while filtration systems like Brita or PUR pitchers make your water tastier and healthier, those disposable filters aren't great for the environment. A new eco-friendly water filter aims to change that.

The Phox water filter features a reusable cartridge that you can refill with packets of filtration mixture once a month. The five-stage filter design—which you fill with the company’s coconut shell-based purification powder—softens hard water, improves taste, and removes chlorine, copper, lead, and mercury. The 1-liter pitcher takes roughly eight minutes to filter.

The purification packets come in two different mixture options. The Clean Pack removes contaminants, odors, and heavy minerals, but doesn’t add any flavors. It makes the pH of your water neutral or slightly acidic, perfect for water you're going to use for coffee or tea. The Electrolyte Option, meanwhile, removes all the same contaminants, but also adds in sodium, calcium, and magnesium. This makes the water alkaline, with a pH somewhere between 8.0 and 9.5. (There’s little scientific evidence to show that alkaline water provides any health benefits, but some athletes swear by drinking alkaline water to improve performance. Others just enjoy the taste all those minerals lend the water.)

The Glasgow-based Phox Water estimates that 100 million plastic water-filtration cartridges end up in landfills every year. To make a more environmentally responsible product, Phox’s pitcher and refillable cartridge are made out of recycled plastic, and its refill packets are shipped in cardboard and paper. Each filtration pack lasts approximately 45 days (or 44 gallons).

Buy it on Kickstarter for $59 and up, with shipping scheduled for August 2019. Refill packets will cost about $9 each for a 45-day supply.
