CleanSip is a portable water filter in a straw form, designed to reduce contaminants such as heavy metals (lead, mercury, arsenic) and pathogens like E. coli. It uses a five-stage ionic purification system, combining microfilters, activated charcoal, and a high-purity metal alloy to electroplate contaminants. Ideal for travel, camping, and everyday use, CleanSip can purify water for 4 to 6 months and comes in various colors with a carrying case for protection.
