A kitchen in the evening, the Kaldera Glass on the counter with the lid lifted off and the glass bowl carried toward the table
About Kaldera

It started with a basket.

The third air fryer in four years. The coating was coming off in the potatoes by month ten, and the box had said all the right things. It could have been built better. Nobody had bothered.

The story

The cheap one died. The expensive one peeled.

The first air fryer was the cheap one, and it stopped heating inside a year. The second cost more, came in a beautiful box, and by month ten the black coating in the basket was coming off in the potatoes. We looked inside the third one before buying it and found the same thing under a different word on the sticker.

So we asked a simple question. What if nothing that touches the food could peel? A glass bowl. Steel racks. A lid you lift off so the bowl can go to the table and then into the dishwasher. A temperature you choose yourself, not one a preset chose for you. None of that turned out to be difficult. It was just cheaper not to do it.

Then we looked at the rest of the kitchen and found the same answer waiting everywhere: glass or bare steel where it matters, a real temperature setting where the sticker used to be, and a warranty long enough to mean it.

We called it Kaldera, after the bowl a fire leaves behind.

Every Kaldera comes with a 2-year warranty and 60 days at home to decide, because we know what is inside it.

Three standards

Three things every Kaldera has to pass.

Nothing coated where the food is.

Glass or bare stainless steel on every surface that touches what you eat. If a part could be "ceramic" or "non-stick", the answer is no. Every material is named on the product page.

glass and steel, every time
You are in charge of the heat.

A temperature you set and a time you set, on every product. Presets can be a shortcut. They are never the only option.

your setting, not a guess
Two years, and sixty days to be sure.

A 2-year warranty on everything. Sixty days at home to decide, no restocking fee. If a product cannot carry that, it does not get made.

What you get

Glass you can see through. Steel you can scrub. Years you can count on.

Thousands of kitchens have already made the switch. Here is what they found.

"Read the whole page twice looking for the catch, because every one of these says it is safe until the coating goes. Six weeks of dinners in the dishwasher and the basket looks exactly like it did in the box. That's all I ever wanted from one of these."
