In this fast-paced world, time is, more often than not, not on our side. 

Nevertheless, no matter how busy or in a hurry we are, we always make time for coffee. 

For people on the go, single-serve coffee makers are the gift that keeps on giving. 

If you are considering buying a model, this article will compare two high-quality products from the company Keurig. 

The Keurig K40 and K45 are quite similar in their styles and technology. 

In fact, both come from the company’s Elite product line of low-end coffee makers. 

With their simple design and below-average price point, the K40 and K45 are a steal for those always in the rush.

This comparison aims to lay down the features each product offers, ultimately helping you decide on what item to get. 

Form and Construction 

Both the K40 and K45 sport similar styles with the brand’s signature top-loading design.

The two coffee makers come with a detachable 48-ounce water reservoir and a removable drip tray for easy cleaning and maintenance.

Both Keurig coffee makers are made of durable materials and come in a sleek and stylish black color, making them blend well in most kitchens and counters. 

Nevertheless, many users tend to prefer the K45’s design more. 

Controls 

Both Keurig coffee machines come in a practical and straightforward design and a color touch screen. 

The buttons are easy to familiarize and navigate due to their intuitive controls. 

Moreover, both coffee makers also come with an auto-off/on function. 

Both the K40 and K45 come with LED indicators that signify various conditions like when the machine requires more water, when it needs cleaning, when it is heating water up, when it is on, and the like. 

The coffee machines’ buttons enable you to choose the cup size and power. 

However, unlike newer models, these Keurig coffee makers do not allow for any adjustments to the brew strength and temperature. 

Nonetheless, if you are looking for a fast and easy way to brew coffee in the mornings, both appliances are solid choices. 

Compatibility 

Both the Keurig K40 and K45 are compatible with the company’s licensed K-cups as well as the My K-Cup Pods. 

The licensed K-cups come in various flavors ranging from the classics and some new and more exciting flavors. You can easily purchase a pack on the company’s website or in local physical stores and trusted online shops.  

However, you can also opt to use your ground coffee of choice by placing it inside the My K-Cup Pod. 

Brew Sizes 

The Keurig K40 and K45 can accommodate drink sizes of six, eight, and ten ounces. Just press the chosen beverage size button on the controls. 

Nevertheless, both Keurig coffee makers can cater to larger mugs and cups. You need to remove the coffee maker’s drip tray to obtain more space. 

However, it is vital to remember that a bigger cup size might affect the brew’s strength and taste due to the water-to-coffee ratio. So, proceed at your own risk. 

Brewing Time 

Both Keurig coffee makers also take the same amount of time (more or less) when brewing a single cup. 

After popping in the coffee pod, the K40 brews a cup in less than a minute. On the other hand, the K45 can brew a single cup in forty-five seconds. 

Water Filter 

What differentiates the two Keurig coffee makers is that the K45 model has a water filtration system, while the K40 does not. 

However, the absence of a water filter in the latter is not a dealbreaker for many since one can always purchase a separate water filter.

 Moreover, some users may already have a water filtration system installed in their homes. 

Nevertheless, if you live in an area with hard water, the K45 can be a good investment

For one, you wouldn’t have to spend a second time nor go through the hassle of buying and installing a water filter. 

Moreover, using filtered water can also improve your coffee’s taste and aroma. 

Filtered water also makes it easier to clean and maintain the coffee machine since there is less scale build-up. 

Bonus K-Cups 

As mentioned, both Keurig coffee makers come with a pack of K-cups when you purchase them – with the K40 giving you six pieces while the K45 has twelve pieces. 

As such, the K45 is a bit better, considering it offers a more extensive range of coffee choices and variety. 

The extra K-cups also make it a great housewarming or birthday gift. 

Price 

Both Keurig coffee makers are available on Amazon, with the K40 retailing at $170.99 and the K45 pricing at $119 (as of this writing). 

However, many recommend browsing other stores and shops for these coffee makers first before you make your purchase. 

Some retailers and shops offer them at huge deals and discounts, considering that they are already older Keurig models

Conclusion 

As mentioned in the article, both Keurig coffee makers offer more or less the same benefits and work on the same technology. 

The only difference between them is that one model comes with a water filter and more K-cup variety while the other does not. 

If you are looking for a practical and straightforward application, then the K40 is a solid choice.
