The very simplest coffee machines are our single and double pod brewers - perfect for personal use. It is great to have one of these in your office. And for the Hotel or Country Inn, these are excellent to leave in your guestrooms. Guests can make their own coffee, and there is almost no cleanup for your cleaning staff.
For personal home use, we next have standard Bunn drip coffee makers that make a pot at a time.
And then we have large commercial grade coffee machines. These are made for commercial use, but are not actually NSF certified. They are perfect for a large office. If you are a commercial food service business, check with your Board of Health to see what certifications are required.
Finally, we have commercial coffee brewing equipment certified for commercial use. These are for restaurants and professional coffee shops.
