What size Bottle does the WAYFARER™ Lid fit?

The WAYFARER™ is a standard lid size like our 800ml STAINLESS BOTTLE measuring 43mm/1.7” in diameter. The inside diameter of your stainless steel bottle should measure 44-45mm/1.75” in diameter.

Chances are, if you scratch around the house you’ll find an old bottle that 's compatible. 

Think brands like:

Klean Kanteen’s ‘Classic’ range 

Hydro Flask’s ‘Standard Mouth’ range

4Ocean’s insulated bottles 

...and countless other brands!

How long does each Purifier last? How do I know when it is reaching the end of its lifespan?

Each purifier lasts for 3 months travel (150-200L depending on water turbidity). As the purifier nears the end of its lifespan, impurities build-up and water passes through the purifier slower. When water stops passing through, it’s time to replace your purifier cartridge.

Purification capabilities do not diminish with use.

What materials are used to construct the WAYFARER™?

The WAYFARER™ was designed with the planet in mind. Made from recyclable and compostable materials, yet extremely durable to perform in harsh environments, withstanding use travelling and during outdoor adventures. 

The lid and purifier cartridge are made from Polypropylene #5 (PP) and Silicone, both of which are food-grade, non-leaching, BPA-free and recyclable, weighing in at only 85g.

Senda’s 1L bottle is made from high strength 304 Stainless Steel, food-grade, durable scratch-resistant powder coating, single wall weighing in at only 170g.

The purifier media is completely compostable. It can be removed from the PP cartridge at the end of life and placed in your home compost before sending cartridge to be recycled.
