"Big disappointment" star star_border star_border star_border star_border Since you no longer stock LifeStraw filters,I ordered this system instead. The water tasted odd after only a few days and the cartridge needed replacement after a couple of weeks. The cartridges are expensive, heavy and very wasteful. A simple carbon filter is all that is needed to remove the chlorine taste. I shall seek a simpler replacement. It is also very ugly. Mrs Hendy - 20 September 2021 support_agent A note from the team The ZeroWater filter removes heavy metals such as lead and mercury as well as chemical compounds like nitrates and chlorine, and any fluoride taste. If you're only looking to remove the chlorine then another filter jug may be more suitable. The filter will need changing sooner if you live in a hard water area and there's a high amount of dissolved solids in the water.
