The device has two modes, one to purify water from taps or public fountains, the other for streams and ponds—a potential godsend for hikers and campers accustomed to boiling their water or adding foul-­tasting drops. The cap is rechargeable and­ ­compatible with most reusable bottles. Pricing for a cap-and-bottle pair starts at $69.99\. _—­Simmone Shah_ **Buy now:** [CrazyCap](https://amzn.to/3kEB7qZ "undefined") ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2020/5911398/crazycap/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2020/5911398/crazycap/"},"headline":"The ­Portable Purifier","datePublished":"2020-11-19T13:51:35.000Z","dateModified":"2026-03-02T23:45:52.399Z","description":"","url":"https://time.com/collections/best-inventions-2020/5911398/crazycap/","keywords":["list","franchise","best inventions","Best Inventions 2020"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd24a965e0cec8bf4/698a14324ee26246733181b4/best-inventions-of-2020-CrazyCap-0.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"creator":"TIME Staff","articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd24a965e0cec8bf4/698a14324ee26246733181b4/best-inventions-of-2020-CrazyCap-0.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/collections/best-inventions-2020/5911398/crazycap/","name":"The ­Portable Purifier"}}]}] ```
