The healthy, clean & safe choice
What is Tritan?
We choose to manufacture with a material called Eastman Tritan. Tritan is a BPA-free plastic — it is not manufactured with bisphenol A (BPA) or other bisphenol compounds, such as bisphenol S (BPS).
BPA-Free
Tritan is BPA Free and won’t leach in any way making it the healthy, clean & safe choice.
Tick of Approval
Tritan has been reviewed independently & approved by the European Union FSA, US FDA, Health Canada, Japans HOSPA & Australia’s standards. This means you can use your bottle knowing it is safe and won’t leach after time.
Why is Tritan the perfect material for a water bottle?
Tritan won’t retain smells or odours and is a safe, reusable product, making it perfect to be the material used to produced filter water bottles.
Tritan is also exceptionally durable. This material is shatterproof, unlike glass. This means your 321 Water Bottle is built to last and won’t shatter like a glass bottle would if dropped. Being able to take your 321 Filter Water Bottle on the go without the fear of it shattering if dropped, means you can fill up from any tap, plunge to filter and sip fresh filtered water wherever you are.

Tennie Chen is responsible for sourcing and supplier evaluation, with a focus on balancing product quality, cost efficiency, and supply chain reliability. My role involves identifying trustworthy manufacturers, comparing quotations, analyzing total landed costs, and ensuring compliance with international standards. I always prioritize long-term partnerships over one-time deals, aiming to work with suppliers who can provide consistent quality, competitive pricing, and flexible solutions. When making purchasing decisions, I evaluate not only the product itself but also the supplier’s production capacity, lead time, and after-sales support, ensuring that every cooperation contributes to sustainable business growth.
