Since 2013 · Foshan, China

Drink Different.

We design counter-top water dispensers — sparkling is the plus one. And we build them ourselves.

At 4°C, carbon dioxide and water meet at their best. That single fact gave us our name, our obsession, and a question we have been answering since 2013: what if your drink could be exactly yours?

Water first

Soda makers don't sell. Water does.

Ask a buyer what this is and you will hear “soda maker”. That names the mechanism, not the business. What sits on the counter is a counter-top water dispenser — an appliance the trade already knows how to shelve, price and sell.

And the machine is not the thing that gets bought twice. Water is. Sparkling is what turns water from the cheapest thing in the kitchen into something people choose on purpose — and once it becomes their default, they drink it every day.

That is the difference between a gadget and a line. A gadget sells once. A habit sells every month — bottles, gas and refills right behind it. Same machine, wider shelf, and now a reason to come back.

Two companies. One idea.

HK 4 Degree Co., Ltd

We design. We dream it up, we draw it, we work out how it should feel in your hand.

Foshan Mia Electrical Appliance Manufacturing Co., Ltd

We build. We tool it, we mould it, we inspect it, we ship it.

Because we build our own designs, nothing gets lost in translation.

Orders are contracted through Foshan Shunde Four Degree Technology Co., Ltd — same building, same team.

The part most brands skip

60 granted patents across 4° and MIA — 56 of them in force today. An 8-person R&D team. 10% of what we earn, put back into R&D — every year, not once.

We don't buy a machine, print a logo on it and call it ours. We start at the sketch, and we stay with it until the last bottle has passed inspection.

Customer case

Sparkling water, built into a fridge.

A global smart-appliance brand asked us to put carbonation behind a refrigerator door. We developed the module, tooled it, and proved it on our own life-cycle rigs before release — and it shipped in 2026.
