FAQ

Coffee & Bakeware — FAQ

How do I choose between k duo keurig models?

Consider your daily volume needs. If you serve guests or drink multiple cups, a dual-function carafe model is superior.

Are replacement filters necessary?

Yes, using a filter kit prevents scale buildup and improves the flavor of your coffee. It significantly extends the lifespan of your brewer.

Can I use ground coffee in all models?

No, most single-serve models are pod-exclusive. You must select a specific duo-capable unit if you prefer using ground coffee.

What is MultiStream technology?

It is a brewing method that uses multiple needles to saturate the coffee grounds evenly. This results in a more robust and flavorful cup.

Is the WiFi feature worth the cost?

For those who value convenience and custom settings, the app integration is a game changer. It allows for precise control over your morning routine.

We recommend descaling every three to six months depending on your water hardness. Regular maintenance ensures optimal performance.
