2-Year Limited Warranty
Every Metaiosin vessel is built to be used daily and repaired, not replaced. This is what our warranty covers.
What the warranty covers
For two years from the date of delivery, we will repair or replace, at our choice, any Metaiosin product that fails under normal use because of a material or manufacturing defect. This includes leaks from the vacuum seal, a lid or closure that will not seat, and finishes that delaminate or corrode without cause.
What the warranty does not cover
- Normal wear and tear, scratches, dents or faded finishes from daily use
- Damage from drops, knocks, fire, freezing, or misuse (for example putting a non-dishwasher-safe body in the dishwasher)
- Electronics inside capped products (UV, solar, hydration-tracking) if the sealed cap has been opened, submerged, or damaged by water ingress
- Consumable parts: filters, mineral cartridges, seals and gaskets are wear items and are covered only if faulty on arrival
- Products bought second-hand or from an unauthorised reseller
How to make a claim
- Email service@metaiosin.com with your order number, a photo of the fault, and a one-line description.
- We confirm within 1–2 business days whether it is covered and what we need next.
- If it is covered, we send a replacement product or the relevant spare part, including shipping — or we refund you, your choice.
Proof of purchase
Keep your order confirmation email — your order number is enough to start a claim. We do not require a printed receipt.
About the two-year promise
Two years is our baseline. Many parts are available as spares well beyond that, so if something fails later, email us anyway — see our Replacement Parts page.
