Family members that also bought ZeroWater (based on my recommendation) also had the same issue so I know I didn’t get a one-off faulty device.

Chlorine in your drinking water may sound strange, but it is actually a very common practice for water treatment facilities to add chlorine to the water supply as a disinfectant. This is extremely effective at getting rid of other, nastier contaminants in the water, but the World Health Organization estimates that a concentration of ~0.2-4 ppm is standard for tap water, indicating that at least some is left over after disinfection. The ion exchange stage removes almost all dissolved contaminants and heavy metals. Especially those that might still appear after public water system treatments. This includes traces of lead, nitrate, aluminum, zinc and lead. Do not keep the water filter near the window. The sunlight creates a suitable condition inside the filter when heated up. The heat creates humid conditions inside the filter, perfect for the bacteria to multiply and grow their community.Connect two parts of the filter into a pitcher with the help of the O-ring. O-Ring is made of rubber material that provides waterproof sealing to the two parts of the container. It seals the to zero water filter parts and stays at the position. Also, the same study done for the water filter from the ZeroWater provides a pH level of 7.75, which is considered perfect for the drinking water category.

Each filter will turn up to 150 litres of tap water into ZeroWater, but this depends on the original quality of your tap water and the amount of dissolved solids, so they will last longer in soft water areas. Enjoy great-tasting water with the latest filter technology. The ZeroWater filtration system combines FIVE sophisticated technologies that work together to remove virtually all dissolved solids from your tap water, delivering you great tasting water. These are the only pour-through filters on the market certified by the NSF to reduce lead.ZeroWater UK’s carefully designed jugs and dispensers are fitted with filter systems which can catch even the tiniest of particles floating its way through your tap water. The brand estimates that their filters can remove a whopping 99.6% of dissolved solids found naturally in the UK water supply! ZeroWater eliminates 99.6% of the total dissolved solids compared to Brita, removing only 49.6%. The table below gives a clear indication of how much more Zero is able to remove when compared to Brita. ZeroWater’s 5 Stage Ion Exchange Filter is the only pour-through water filter NSF certified to reduce PFOA/PFOS, lead, and chromium.
