FAQ

Coffee & Bakeware — FAQ

Is the keurig k3500 suitable for home use?

While powerful, it is primarily designed for commercial environments. It may be overkill for a standard home kitchen.

How often should I change my water filter?

We recommend replacing filters every two months or after 60 tank refills. This keeps your coffee tasting fresh and protects the machine.

Can I use my own coffee grounds?

Yes, most models are compatible with universal reusable filters. This allows you to use your favorite fresh-ground beans.

Why is my coffee not hot enough?

Ensure your machine is fully preheated before brewing. If the issue persists, check if the water reservoir is properly seated.

Does the K-Supreme fit large travel mugs?

Yes, the drip tray is removable to accommodate taller travel mugs. This makes it very versatile for morning commuters.

What is the benefit of MultiStream technology?

It saturates the coffee grounds more evenly than a single needle. This results in a fuller, more balanced flavor profile.
