We are here to provide a solution to an ever increasing single-use plastic problem. In the pursuit of clean and tasty water, millions of filter cartridges go to landfill each year. In 2019 we decided to put an end to that by creating the first refillable filter cartridge.

To reduce our carbon footprint, we focused on finding UK companies to supply as many raw materials as possible. The manufacturing, packaging and design is all done within a 30 mile radius of our office in Glasgow.

The Alkaline Pack

Enjoy the benefits of magnesium enriched hydration. Our Alkaline pack maintains the calcium content, increases magnesium and pH. Removes Lead, Copper and Chlorine.

This pack does not soften hard water (reduce minerals). If that's important to you please check out our clean and softener packs.

Have to admit to being a bit cynical. Got the alkaline pack as I suffer from Acid Reflux. I now don't need the reflux medication, and overall find myself recovering quicker from heavy gym sessions.

K Parker

Fantastic product! Arrived promptly, well packaged and with lear instrcutions. The app is really helpful and the water tastes delicious. I went for the alkaline option and it has really helped with my reflux issues.


I've been using Phox water jug and alkaline refills for a couple of years now. I love that I drink more water from the jug and have done away with bottled water. The alkaline filtration is good for my stomach. The just looks nice in my kitchen too!


Love my phox filter. The weight of throwing filters in the bin each month got too much, I was so pleased to come across the compatible cartridge. I went with the Alkaline pack and the water tastes fantastic. Really really pleased. Highly recommend!

Delighted with the Phox compatible cartridge - great-tasting water, high quality filtration, and no more Brita Maxtra plastic to throw away! I went for the Clean cartridge to trial the product in my existing Brita jug, and will definitely be switching to the full-on Phox jug later on.

Jenny Glover

I got the clean pack water tastes fresh and nice all the chemical smell and tastes removed. I live in a very hard water area so I recommend this over the Alkaline tried that too but made my water taste very acidic

It was so easy to set up, I bought the 'Clean' pack and you really can taste a difference in the water.


I’m so glad I discovered Phox water filters! I have the clean filter for my hot water kettle and the alkaline filter for my drinking water pitcher in the fridge. Now I can feel even better about reducing the single use plastic I hate so much!


I love this product both the water filter and the brita substitute cartridge I now have two pitchers one with the clean pack and one for after exercise using the alkaline pack. Well done for reducing plastic waste and the taste is amazing
