Keurig Mini Plus Cons

Despite the K-Mini Plus being the smallest Keurig for great coffee, it has a few shortcomings that include

1. Adding Water for Every Brew Cycle

You have to refill the water in the water tank every time you want to make a cup of coffee. Unlike large coffee makers that have big tanks that make a few coffee cups continuously without refilling the reservoir, the K-mini plus requires that you add water for every cup.

However, this is a welcome compromise as it’s to be expected for the size of this coffee maker and it does not affect the quality of the brew. This single-serve Keurig brewer is fast as it brews each cup of coffee in two minutes.

2. Height Clearance When the Tank is Open

The Keurig K-Mini Plus stands at about 16.8 inches when the lid is open as compared to the older Keurig K-15 which measures 12.8 inches with the lid open. So, if your countertop has limited height clearance, you may not be able to open the lid and add water for example.

To overcome this, simply remove the water tank and add water to it before replacing it in the brewer. Alternatively, use a goose-necked kettle to add water so that you do not have to open the lid all the way up.

The Keurig K-Mini Plus and the K-Mini were made taller than the K-15 to fit taller travel mugs so the height issue is an acceptable compromise.

3. No Water Filter

Both the K-Mini and K-Mini Plus do not use water filters as their water tanks are too tiny to fit a filter handle. However, you can drop a charcoal filter in the tank without any handle when brewing with unfiltered water.
