Keurig K-45 Overview

The K45 is a flagship brewer from Keurig that was initially introduced as an upgraded version of the B45, but both models have the same specifications. However, the K45 has been discontinued, and Keurig has replaced it with the K-Classic, which has similar features such as a 48 oz reservoir, auto-on/off functionality, and a removable drip tray. 

Unlike the K45, the K-Classic has a slightly upgraded brewing system that ensures the user is brewing with the latest technology for hotter, stronger cups. Additionally, the K-Classic offers expanded brew sizes of 6, 8, and 10 oz. There are also four similar-looking models, including K40, K45, K50, and K55. The K40 and K45 were initially released as the K-Elite brewers, with the latter coming with a water filter starter kit. However, in 2015, Keurig rebranded the K40 and K45 as the K50 and K55 K-Classic brewers.

When considering which Keurig model to choose, it’s important to compare the features and specifications of each model. The K-Classic is an excellent replacement for the K45, with its upgraded brewing system and expanded brew sizes. However, if you prefer a water filter starter kit, then the K45 might be a better choice for you. It’s also worth noting that the K40 and K50 are the same as the K45 and K55, respectively, and have similar features. Ultimately, it’s important to choose a Keurig model that fits your specific needs, whether it’s a larger water reservoir, customizable brew options, or other additional features.

Keurig K-45 Features in Detail

Examining a Keurig coffee maker’s features in detail is essential to make an informed purchasing decision. Understanding the differences in brewing size, water reservoir, brewing temperature, and programmable options can help you select a model that best fits your needs and preferences, ensuring a satisfying and customized coffee experience.

Check out the Keurig K-40’s features in detail and decide if it suits your preferences:

Product Line/System: What is the Product Line/System of the Keurig K-45?

The Keurig K-40 is part of Keurig’s K-Classic line of coffee makers.

The Keurig K-40 is part of the K-Classic line of coffee makers produced by Keurig. This line features simple and easy-to-use coffee makers with basic functions and a compact design. The K-Classic line is known for its reliability and affordability, and the K-40 is one of the most popular models in the line. It features a 48 oz reservoir, a removable drip tray, and compatibility with K-Cup pods, making it a convenient choice for single-serve brewing. While the K-40 has been discontinued, it has been replaced by newer models in the K-Classic line that offer similar features and functionality.

K-Cup Compatibility: Is the Keurig K-40 compatible with K-Cups?

Yes, the Keurig K-45 is compatible with K-Cups, which is one of its primary features. It is designed to work with the entire line of Keurig’s K-Cup pods, giving users a wide variety of coffee, tea, and hot cocoa options to choose from. Additionally, it is compatible with most third-party K-Cup pods.

Brew Sizes 

The Keurig K-45 offers three brew sizes: 6 oz., 8 oz., and 10 oz. This allows users to adjust the strength and size of their coffee depending on their preferences. The larger 10 oz. brew size is particularly convenient for those who want a bigger cup of coffee to start their day.

Water Reservoir 

The Keurig K-45 has a removable 48-ounce water reservoir, which allows for easy filling and cleaning. The water reservoir is made of clear plastic, which makes it easy to see when it needs to be refilled. The removable design of the reservoir also makes it convenient to refill the machine with water when needed.

Does The Keurig K-45 Have A Water Filter?

Yes, the Keurig K-45 has a water filter. It comes with a charcoal filter that can be placed in the water reservoir to help remove impurities and improve the taste of the brewed coffee. The machine will prompt you to replace the filter after a certain number of brews, and the display will indicate when it’s time to do so.

What Type of Display Keurig K-45 Has?

The Keurig K-45 coffee maker features a blue backlit LCD display that shows various information such as the brew size, brewing status, and auto-off programming. The display is easy to read and user-friendly, allowing you to quickly and easily navigate through the machine’s settings and options.

Does The Keurig K-45 Have A Temp Control?

No, the Keurig K-45 does not have a temperature control feature. This is because the K-45 is one of Keurig’s earlier models, and temperature control was not a standard feature at the time of its release. The K-45 only has a single brewing temperature setting, which is designed to produce a consistent cup of coffee every time. However, some Keurig models released after the K-45 do offer temperature control, allowing users to adjust the temperature to their personal preference.

Does The Keurig K-45 Have A Strength Control?

No, the Keurig K-45 does not have a strength control feature. This feature is only available on some of the newer Keurig models. The K-45 was released in 2013 and was designed as a more basic and affordable model. It has a straightforward operation with a few essential features, such as a brew size selector and a removable drip tray. The lack of strength control is not a significant drawback, as the K-45 still allows you to adjust the brew size and strength by using different K-Cup pods.


The Keurig K-45 coffee maker measures approximately 13.0 inches in height, 9.8 inches in width, and 13.3 inches in depth. The machine has a compact and sleek design that allows it to fit comfortably on most kitchen countertops without taking up too much space.


The Keurig K-45 coffee maker has a weight of approximately 12 pounds. The machine is relatively lightweight and easy to move around, which is especially convenient if you need to store it away or transport it to different locations.

Quiet Brew Technology 

No, the Keurig K-45 coffee maker does not feature Quiet Brew Technology. This technology is typically found on newer Keurig models and is designed to reduce noise during the brewing process. However, the K-45 still has a relatively quiet operation compared to traditional coffee makers, making it a great option for households where noise is a concern.

Does The Keurig K-45 Have An Auto-On/Off Feature?

No, the Keurig K-45 coffee maker does not have an auto-on/off feature. This feature is typically found on newer Keurig models and allows you to program the machine to turn on and off automatically at specific times. However, the K-45 does have a built-in auto-off function that turns the machine off after two hours of inactivity, which helps to conserve energy and improve safety.

Does The Keurig K-40 Have A Removable Drip Tray?

Yes, the Keurig K-45 coffee maker has a removable drip tray that makes it easy to clean and maintain. The drip tray is located at the bottom of the machine and can be easily removed to empty excess water and coffee residue. This feature helps to prevent messes and spills on your countertop, and makes it easy to clean the machine after each use. Additionally, the K-45 also has a removable water reservoir for easy refilling and cleaning.

Does The Keurig K-45 Come With A K-Cup Variety Pack?

Yes, the Keurig K-45 coffee maker typically comes with a K-Cup variety pack that includes several different flavors of coffee and tea. The specific variety pack may vary depending on the retailer or seller, but it usually includes a selection of popular K-Cup flavors from different brands. This is a great way to try out different flavors and find your favorites before purchasing larger packs of K-Cups.

What We Like?

Here are some of the features that welike in the Keurig K-45 coffee maker:

  • Compact and space-saving design
  • Easy to use and clean

  • Quick and convenient brewing process
  • Adjustable brew size options
  • Removable drip tray and water reservoir for easy cleaning and refilling

What We Don’t Like?

Here are some of the potential drawbacks or issues that some people have reported with the Keurig K-45 coffee maker:

  • Noisy operation during brewing process
  • Limited brewing capacity (single cup at a time)
  • Some users have reported issues with the durability of the machine over time
  • The machine may not be compatible with certain third-party K-Cups or reusable filters
  • The lack of advanced features found on newer Keurig models, such as auto-on/off programming or temperature control settings
  • Some users have reported issues with clogging or leaking, especially with prolonged use or frequent brewing.

Is Keurig K-45 for You?

If you are considering purchasing the Keurig K-45 coffee maker, it is important to keep in mind that it has been discontinued and may be more difficult to find. However, if you are able to find a good deal on the K-45, it is still a quality model that is worth considering. While it may not have some of the newer features found on more recent Keurig models, it still offers a quick and convenient brewing process with adjustable brew sizes. 

If you are interested in the K-45 but do not need the water filter starter kit that comes with it, you may want to consider the K-40 as an alternative. 

However, if you want a newer model that is currently in production and supported by Keurig, we recommend the K-Classic. The K-Classic has all of the features you would find on K40-K55 brewers and is a great choice for anyone looking for a reliable and easy-to-use coffee maker.
