The Waters Co Bio 400 Bench Top Water Filter is the same size as the Bio 500 but comes with white housing. It is a good size for the home and smaller workplaces. It is a complete gravity-fed bench top system which isn't plumbed in and doesn't require electricity. You simply add water to the top and great tasting alkaline mineral water comes out the bottom via a chrome tap.

Waters Co is based in Hong Kong and has over 30 years of history making bench top water filtration systems. 

Waters Co Bio 400 offers high levels of fluoride removal - up to 99% removal.

Size: 5.25 Litre glass reservoir capacity


  • Hand blown blue glass reservoir made from silica
  • BPA free and non leeching plastic housing
  • Solid chrome tap
  • Turns tap water into great tasting alkaline mineral water with a pH between 7.4 - 8.5
  • Patented nano carbon compound for removing up to 99% fluoride. This is a natural ion exchange cation resin.
  • 13 stages of filtration and activation across 6 multi-stage cartridges
  • Sub micron pre filter removes dirt, sediments, rust, bacteria and high levels of copper. This filter helps to extend the life of the subsequent filters.
  • 1st stage carbon resin filter removes fluoride, chlorine, trihalomethanes, pesticides, heavy metals and  bacteria
  • Main mineral filter removes fluoride, chlorine, trihalomethanes, pesticides, heavy metals and bacteria while adding natural trace minerals from coral and silica sands
  • Bio ceramic pot is made from kiln fired silver ionised coral, silica and mineral sands adding natural trace minerals to water. The bio ceramic pot activates the filtered water keeping it fresh and preventing bacteria from propagating in the system.
  • Far infrared diskette helps to balance the pH to slightly alkaline
  • Sub mineral cartridge sits inside the glass bowl and adds organic germanium and over 60 bio organic trace minerals to the water helping to keep it fresh and tasting good.
  • Magnets on the tap which ionises and magnetises the water
