The RapidPure® Universal Purifier water bottle adapter turns your favorite wide mouth water bottle into an advanced water filter and purifier to provide you with safe, great-tasting water.

This water bottle purifier works with Nalgene®, CamelBack®, Hydro Flask®, and Klean Kanteen® wide mouth bottles and features RapidPure's innovative technology.

Unlike microfilters that rely on pore size to simply filter out bacteria and sediment, RapidPure water treatment actually purifies water using electroadsorption, removing bacteria, parasites, viruses, parasites, chemicals, heavy metals, pesticides, and microplastics, as well as filtering out sediment. With no pumping, priming, or squeezing required
