Best Coffee Maker for Hard Water In 2021

Below are all these specifications in detail and much more including some of the best brands like Hamilton Beach and Mr. Coffee. Read below to find out the coffee maker o your choice for hard water. 

1: Mr. Coffee 31160392 Programmable Coffee Maker

Mr.Coffee originated as an all-coffee company and has focused all of its services on one item: coffee. The Mr. Coffee programmable coffee maker is one of a kind as it has a large capacity along with the richest coffee-producing technology. 

Read on to learn much more about the specifications of Mr. Coffee’s 31160392 configurable coffee machine.


Easy coffee is no difficult feat with the help of Mr. Coffee’s easy-measuring programmable coffee maker with a 12-cup capacity that lets you make delicious coffee instantly. Coffee ground and water can be easily measured with the help of the color-coded measuring system, a trait absent in most makers. That allows you to get the perfect cup every time.

Water handling

The updated coffee maker also improves the taste by smart technology. 

A 2-step advanced water filtration system is installed to reduce impurities in water which improves the state of the hard water. It has 2 stages – the first one uses activated carbon while the second one uses ion exchange resin – these reduce 97% choline, calcium and provides particle filtration. Combined, this helps clean up the water and only gives you the best.


The coffee grounds go through a process known as ‘Blooming’. Blooming is a process in which beans are presoaked to absorb the maximum amount of flavor before brewing and it takes only 30 seconds. This releases carbon dioxide and gives you only fresh rich flavor in your drink.

Additional traits

A 4-hour freshness indicator is included to avoid stale coffee and a brew now/later option as well. The auto-pause lets you grab a cup before the brewing is finished to cater to your preferences. 

This small drip coffee maker has a gold-tone reusable filter, a brew basket with an even larger capacity to add to the 12-cup one already present, and a 4-hour long shutoff. The convenient clean cycle further saves all hassle and maintains quality taste. It also arrives with one-year protection for your satisfaction.

  • Has 4-hour freshness indicator
  • Presoaks coffee for better results
  • Gold-tone reusable basket filter included
  • Takes a long time to brew coffee

2: Cuisinart DCC-1150BKP1 Classic Thermal Programmable Coffeemaker

The next on the list is one brand I’m biased about when it comes to trust – Cuisinart. The Cuisinart thermal programmable coffee maker is an embodiment of the brand’s reliability. Everything from its double-wall insulation to charcoal water filter hints at the detail invested in the product. 


The Cuisinart coffee maker has a fully automatic 10-cup carafe with a double-wall thermal insulation feature. This keeps the coffee warm for hours and pairs well with the 24-hour programmability function. The coffee can be pre-programmed to have the next day without a hassle in the morning and the insulation will keep it warm in case you sleep in!

Water handling

The coffee maker takes care of both, the hard water as well as extracting the richest coffee taste. You ask how? Well, it does the hard water removal through the upgraded charcoal filter installed and the permanent gold filter guarantees only the richest flavor to pass through. 

These are exactly the features that a coffee maker for hard water should have to deliver the most perfect cup of coffee with maximum flavor and aroma!


Coffee makers don’t need a lot of technological knowledge, and a few basic functions are enough to get the job done. This little coffee maker has a 1-4 cup setting that allows you to choose the amount of coffee you require in a single serving. 

There also is a brew-pause function that lets you remove the coffee mind-brewing to give you control over the flavor. Furthermore, the Cuisinart coffee maker features a self-cleaning function that automatically cleans the insides of the coffee maker, saving you from all the added trouble.

Additional traits

Since there is a mind-brewing pause option that lets you take away your drink in the middle, there is also one that resumes it. What if you sip and don’t like your drink, wanting it to be a tad bit stronger? Or someone else wants it stronger while you prefer your milder? How does the brewing continue then? 

It does so easily with the help of the 60-second reset that remembers the settings of the previous brewing process and continues.

  • Classic design with stainless accents
  • Has gold-tone and charcoal water filter
  • Excellent thermal insulation
  • Turns off automatically
  • Handle turns hot after being dish-washed

3: Nespresso VertuoPlus Coffee and Espresso Maker

Nespresso is known for its luxury coffee machines giving the vibes of those of a coffee place. Their VertuoPlus coffee and espresso maker can serve multiple sizes, a monitored head, and adjustable brewing parameters. 


You can brew different single serve coffee cup sizes including an espresso measuring 1.35 oz and double espresso – 2.7 oz. A gran lungo – 5 oz, a coffee – 7.7 oz, as well as an alto measuring 14 oz are additional sizes. The machine allows you to ur your favorite coffee over ice, creating icy wonders.

Water handling 

The VertuoPlus is a highly efficient machine with a motorized head and a motile 54-ounce water tank. The container can either propel out or remain behind the unit, saving extra room. It has a quick heat-up time of 20 to 25 seconds and automatic shutting after 9 minutes, so it uses very little energy.


The machine’s operation is as simple as it gets, due to the entire system’s reliance on the barcode on the capsule’s bottom. The brewing settings are already managed by the machine requiring no added hassle over and over again.

You can create top-class professional caffeinated drinks whether they be single-serve coffee or espresso cups with just a touch of a button. There is one downside though, that the machine can only be used with Nespresso Vertuo capsules.

Additional traits

Since you cannot use a huge variety of capsules with this machine, it comes equipped with a starter set of these Nespresso capsules. The Aeroccino 3 milk thermal carafe aids in the creation of the ideal finishing for your delightful treat.

  • Easy and convenient to use
  • Has a rotating water tank
  • Reusable capsule promote efficiency
  • Brews small quantity

4: Ninja CE251 Programmable Brewer

Next is one belonging to the Ninja family, the CE251 programmable brewer is a top-notch high-quality classic coffee maker. It has the largest and most versatile brewing capacity and produces flavor in every single cup.


Extreme convenience is when coffee machines can brew both, a large quantity as well as a small one. With this brewer, you can brew as much as 12 cups at once or you can use the small batch function to create 4 cups or less of this caffeinated delight. 

Now you can make coffee for the whole family or merely yourself, there doesn’t have to be the least amount of trouble!

Water handling

There isn’t much for the hard water filter for coffee maker systems, however; you can use magnesium-ion hard water with this little item. Water reservoirs are great but they always cause a mess which is why you can carry this removable 60-ounce reservoir to your sink safely with ease.


The programmable brewer lets you program your day in advance with the 24-hour delay-brew so that you will have your coffee already prepped in the morning. The auto-heating system keeps coffee warm without burning it for up to 4 hours and the freshness isn’t affected as well! The auto-shutoff after 2 hours saves electricity to the maximum.

Additional traits

The machine has one thing that most coffee makers lack – a flavor straw. The purpose of this straw is to circulate the coffee while brewing to ensure flavor and warmth in every sip. I mean, along with all the other traits for a flavorful coffee, a flavor straw as well? 

  • Has programmable delay system
  • Updated small-batch settings
  • Durable glass carafe
  • Cannot detect missing coffee pot

5: Hamilton Beach FlexBrew Coffee Maker

Here comes my favorite brand – Hamilton Beach, along with its FlexBrew coffee maker. Harboring a large capacity, this coffee maker has the most feasible removable water reservoir and 2-in-1 functions.


Harboring quite a large capacity, this 12-cup carafe has a side permanent filter. Extreme convenience is achieved with the help of the programmable timer and auto-pause, along with the auto shut off. You can pre-plan your coffee ventures and not have to worry about saving energy at all now!

Water handling

Again, there is no such filter for hard water however, the water reservoir is pretty easy to fill and even features a water window. This window lets you know the amount of water in the brewer. Simply look at the water and decide when it needs a refill or how many more cups can you manage to gulp on more before the water runs out.


This 2-in-1 coffee maker allows you to use your favorite ground beans for a cup of all-natural goodness or a Keurig K-cup pod for a single-serve. It gives you the choice to choose whichever brew you prefer. 

The coffee doesn’t take long to brew, only about 3 minutes. The flex brew presents you with a strong, great-tasting cup of coffee. Continuous heating of water is pointless and utilizes loads of electricity which is why the flex brew only heats water when you’re ready to brew.

Additional traits

The pod-holder and single-serve ground baskets are included to facilitate the use of k-cup pods and to brew single-cup coffees. The brewer also features a cup rest that can be snuck in to save storage when not in use. The pod piercing needles are used for easy cleaning and prevention of clogs.

  • Easy-view water windows
  • Programmable timer
  • Compatible with a large variety of filters
  • Low durability

6: Braun KF6050WH Brew-Sense Drip Coffee Maker

Next is Braun, a name you might not be that familiar with but trust me their coffee makers are just amazing. But seeing how an infamous brand developed a coffee maker used to combat hard-water problems? It is, without a doubt, a tremendous coffee achievement!


The brew-pause device allows you to pour a cup at any time during the brewing process without wasting a tiny drop. Along with the 12-cup carafe that seals fresh flavor by minimizing air exposure, this is indeed the perfect deal!

Also, you can choose to brew a full pot or anywhere between 1 to 4 cups with the help of these settings. Whichever you choose, you will be guaranteed top-notch excellent results only with the best flavor and aroma on every sip.

Water handling

The device uses a gold-tone filter unlike most coffee makers using non-recyclable paper filters. This not only saves the environment by being reusable but enhances the flavor of your coffee as well by allowing the essential oils to reach every sip. 

In terms of water, a carbon filter sterilizes boiling water, i.e., hard water, and a cleansing function encounters various levels of water toughness. This is a feature lacking in most machines which makes this one the best cheap coffee maker.


A look at this coffee maker and you can tell that it is indeed one of a kind featuring a sleek, elegant design with a smaller footprint. The profile of the machine is small, the panel is super user-friendly, and the cord storage saves even more space.

The programmable 24-hour timer tells you when your coffee will be ready. The auto-shutoff function will switch the unit off without the need for any action on your side. Also, the easy-to-read clock on the front will be easily locatable from over to your living room.

Additional traits

The machine comes along with a unique water level indicator that brews reasonable amounts of water efficiently. When brewing such a large amount, I see it difficult to get by without a water level indicator. 

  • Gold-tone filter enhances the flavor
  • BrewPause system to pause midway
  • An Anti-drip system prevents messes
  • Slightly expensive

7: Zojirushi EC-YTC100XB Coffee Maker

The Zojirushi Coffee Maker is the most durable coffee maker on my list today with its stainless-steel carafe. Even the filter inside is made of permanent stainless mesh to provide optimum flavor. Let’s read below to find out more about the Zojirushi wonders and if this deal is the perfect coffee one for you!


And when not being used, the 10-cup carbon steel decanter stays the coffee hot for hours, and believe me when I state that keeping such a huge volume hot is challenging. The removable water tank makes filling easy even if it’s a full 12 cup and is fully washable.

Water handling

The machine does come with a filter but only for the coffee and none installed for cleaning the hard water. The reusable and washable permanent stainless mesh coffee filter extracts all the flavor from coffee, giving you a rich cup. The set even has a measuring spoon accessory included for ease.


The design is constructed to bear a huge amount of temperature, a good 200 degrees, that brew water to just the right temperature to create the perfect cup of coffee. The drip mechanism prevents the leakage of coffee and wastage when the carafe is removed. This eliminates the need for several trips to the sink to clean up spilling coffee.

Additional traits

The machine is indeed one of a kind as it not only focuses on warm coffee but has a system for cold coffee as well. There is a special measure line for iced coffee to determine the coffee-to-water ratio so that you get a strong coffee. This is way better than the usual diluted iced coffees frequently available.

  • Time saver mode installed for efficiency
  • Vacuum insulation keeps coffee warm
  • Durable construction
  • Takes a long-brewing time

8: Keurig K-Elite Coffee Maker

Last on my list is the Keurig K-Elite, coffee maker. This coffee maker is perfect for everyday use considering its capacity and innumerable options to increase convenience. Let’s check out more of the K-Elite specifications below.


The coffee maker has a lot of different sizes to offer ranging from 4, 6, 8, 10 and even 12 oz meaning it can facilitate a minimum of 4 and a maximum of 12 cups. This gives you the freedom to have the coffee of your choice – whether it be small shots of espresso or whole gallons of dark cappuccinos. 

Water handling

The large reservoir allows for the brewing of 8 cups which not only saves your time but saves you from all that hassle in the morning as well. To further add to your convenience, the removable reservoir makes refilling super easy. 

The machine does not have any such hard-water solutions however it produces hot water on demand through a button. This comes especially handy when making instant soups, oatmeals, porridges, etc. 


The device has one feature that all others lack – it alerts you when it is time to descale your coffee. Since the machine deals with hard water, it is important to descale. Descaling is indeed an essential process as the hard water results in loads of calcium build-up that needs to be removed. 

Descaling does exactly that which improves the taste of your brews and increases the durability of the coffee maker. You just need to search up how to descale a coffee maker and your work will be made easy.

Additional traits

The machine is super easy to use with its updated technology, simply insert a pod, select your desired cup size, and brew your perfect cup in under a minute. It allows you to brew with your coffee as well as with different pods.

Moreover, the strong brew button installed does the favor of increasing the strength and bold taste of your coffee’s flavor with just a single press. Indeed, making coffee has never been easier and if this doesn’t convince you to get this deal, I have little idea what will!

  • Minimum noise production
  • Can be used for instant soups as well
  • Strong coffee ready in minutes
  • The lid needs to be taken off completely
