Built Pure.
By Design

Every Saki product is built to keep what you drink pure. Only stainless steel, glass, and porcelain touch heat or water. These materials are proven to stay stable and safe over time.

Pure Taste, No Plastic

Pure Taste, No Plastic

By removing plastic from the brewing path, we prevent microplastics and keep every cup tasting exactly as it should.

What Touches
Your Water Matters

When exposed to high temperatures, plastics, even those labeled safe, begin to break down. They release microplastics and trace chemicals that are invisible but measurable. Scientific studies confirms how this process accelerates at boiling temperatures.

We designed Saki products to eliminate that entirely. Only stainless steel and glass come into contact with heat and water, materials proven to remain stable and safe through thousands of cycles. The result is simple and consistent: clean water, pure taste, and lasting trust.

Design

Plastic-free design begins at concept. Every component is mapped to keep heat and water away from plastic.

Materials

We source stainless steel, borosilicate glass, and porcelain, materials proven to stay stable and safe under heat.

Engineering

Prototypes undergo heat mapping to eliminate all potential plastic exposure points, from lid to spout.

Safety

Each product is assembled with isolated silicone only for external grip and sealing, never inside the heating path.

Testing

Thermal and corrosion tests verify zero leaching and full structural stability across thousands of heating cycles.

Proof Is in Our
Materials

Every detail matters when purity is the goal.
We engineer each surface from materials that stay
stable under heat and pressure, so what you drink
stays as pure as it was meant to be.

Stainless Steel

No rust. No leaching.
No change in taste.

304-grade stainless steel
for lasting purity.

Borosilicate Glass

Heat-resistant and
crystal-stable to keep
your drink pure and
clear.

preserve flavor.

Porcelain

Tested. Verified.

We’ve partnered with Light Labs to verify that Saki
products are free from BPA, phthalates, and
microplastic release even under boiling heat. Because when it comes to what you drink, purity
should be tested, not trusted.
