Good to know
Questions, answered.
Pre-orders, shipping and testing, in plain words.
When does it ship?
Pre-orders are expected to ship in early 2027. If the date moves, we email you and you can cancel for a full refund.
Which tumblers does it fit?
On its own, Simple Sip fits standard disposable water bottles. With a lid adapter it fits 20 oz and 30 oz Yeti style tumblers and 40 oz Stanley style tumblers with a handle. Simple Sip is not affiliated with Stanley or Yeti; the names describe tumbler styles.
Is it certified?
Not yet. Independent testing to NSF/ANSI standards is underway, and we will post the results here when they are in. Until then we describe what the filter is designed to do and publish no test figures.
