Hard water is the term we use to refer to water that has high mineral content, the principle of which is lime. Now, you can drink lime, but it doesn’t taste very nice, so you want appliances that are capable of purging it from the water you consume.
It also causes limescale build-up, which is problematic for most appliances, severely reducing their functional longevity.
We’ve gathered five kettles below, most of them from brands you’re sure to recognise, which are capable of treating hard water to get rid of lime and other troublesome minerals.
Each entry will have its pros and cons mapped out, and we’ve also included more information about how we judged these kettles in the buyers’ guide below.
Has your kettle packed in? If you need a new kettle as soon as possible then look no further, we have our top kettle choice here to save you the reading.
We chose the Russell Hobbs BRITA Filter Purity Glass Kettle, a series of kettles from one of the more recognizable brands that are packed from top to bottom with features.
See what we mean below:
The kettle retails with a free BRITA MAXTRA+ filtration system that removes minerals from water, including lime and metals, but accepts most BRITA filters. A cartridge replacement panel on the top of the kettle tells you when these filtration cartridges need replacing.
This is a stylish kettle made with premium glass and polished stainless-steel accents that allow you to peer into it and see the water clarity for yourself. It also has a Perfect Pour spout that reduces splashback and ensures you get every drop.
The 360-degree rotating base makes it easy to manoeuvre and pick up for both right and left-handed people.
What better hard water kettle is there than the one that’s Amazon’s Choice for the “brita filter kettle” search term? That’s what the Russell Hobbs BRITA Filter Purity Glass Kettle is, it’s not only a stainless steel and glass kettle that fits stylishly in most kitchens, but it also comes very well-reviewed for its ability to filter minerals from water.
It’s powered by one of the top shelf BRITA filters, the BRITA MAXTRA+, which removes lime, chlorine, and traces of heavy metals from your water when boiling, the removal of which all contribute to the prolongment of this kettle’s lifespan. When the filter cartridges need replacing, the kettle will let you know thanks to a built-in indicator atop the kettle.
At the head of the kettle itself, you’ll find a Perfect Pour spout that reduces water splashing, ensuring no hot water splashes on you and, in doing so, saves you every drop of water to drink. The body of the kettle itself is mainly transparent, premium-grade glass with polished stainless-steel accents which is not only stylish but allows you to clearly see when the water is being boiled.
The body is perched on a 360-degree rotating base that makes it easy to lift for both right and left-handed people. That also makes it easier to manoeuvre when filling it up with water.

At second place on our list is an item that some might not consider a kettle but, whilst you debate with yourself if it is a kettle or not, let us tell you all about it. Another product from Breville, their BRITA HotCup Hot Water Dispenser is Amazon’s Choice for searches for “water boilers for kitchens” and is functionally identical to a kettle.
It’s decked out with BRITA’s own MAXTRA cartridge filters that remove minerals like lime and chlorine, removing it from the 1.8L capacity of this dispenser jug whilst boiling it in under a minute for a speedy and convenient boiling cycle.
The upside of this being a dispenser as opposed to a lifted kettle is the fact that it has nine different settings for cup styles, meaning you can programme your dispenser to your favourite mug so that it fills out perfectly every time. You can also use a separate stop button to end the boiling cycle whilst the water is boiling, or even mid-flow if you need to cut the water off for whatever reason.
The dispenser drip tray is removable to make the cleaning process as simple as can be, and the permanent MAXTRA limescale filter can be cleaned and, once it’s seen all of its use, easily replaced.
The downside of using a dispenser is that it’s not the energy-efficient option, since each boiling cycle dispenses one cup worth of water. Subsequent uses will be faster since the water in the jug will have already been heated, but it’s still additional power usage regardless.

At the midpoint of our list is the kettle that’s likely to be from the most obscure manufacturer in this article, but that’s not an indictment of the product’s quality. The HadinEEon Glass Electric Kettle prides itself on being a great healthy drinking kettle, featuring a pot made from food-grade borosilicate glass that doesn’t scuff or scratch easily, meaning there are no indentations where limescale can take hold.
The filters are made from a combination of stainless steel and BPA-free materials, ensuring that the filter won’t contaminate your liquid in any way. As for the heating element, it’s made with British Strix thermostat technology that automatically turns off shortly after your water has boiled, and it also has boil-dry safety protection so that you can’t break the kettle by accidentally running the kettle with too little water in the jug.
It has an ergonomic handle that has a wide arc away from the kettle jug, allowing you to pick up and maneuver the kettle without burning your hands on the hot glass. Along with the transparent and elegant glass design of this kettle is a ring of blue LED lights that not only look good but intuitively allow you to see when it’s boiling, if the bubbling of the water hadn’t already tipped you off.
That British Strix thermostat tech, in ensuring that the kettle turns off after boiling, creates a twenty to the thirty-second-time gap between the boiling of the water and the end of the actual boiling cycle.

Filter is made from 304 stainless steel and BPA-free materials.
British Strix thermostat technology features boil-dry safety protection for your kettle.

Blue illuminated LEDs make it easy, and pleasing to the eye, to see when the kettle is boiling.
Our fourth kettle is also from Breville and is the Amazon’s Choice product for the search term “fast boil kettle” online. It’s the Breville Impressions Electric Kettle, and since we’re concerned with its hard water treatment capabilities, we’ll start with how this kettle has a convenient and removable, cleanable limescale filter that you can plug back in after cleaning.
As for how it works, it heats its 1.7L water capacity with a 3kW concealed element inside the kettle jug, providing roughly six to eight hot mugs worth of water in mere minutes. You can fill it easily by keeping an eye on the water level, which is made possible by a rear water window. That window also illuminates when the kettle is performing its boiling action, enabling most to see that it’s hot and should be handled with caution. It also looks pretty, which is nice.
It’s an easy kettle to work with, having a 360-degree rotational base that means you can turn the kettle when filling it up from any angle of approach. When turning it, you also don’t have to worry about the kettle slipping or moving along the countertop since it has non-slip feet that keep it in place.
Limescale filter is easy to remove and able to be reused after cleaning.
The 3kW concealed element rapidly boils its 1.7L capacity.

Even the final product on our list is from a recognisable brand, so that should go some way in reassuring you that all products on our list have a satisfying degree of quality no matter where they land on it.
We’re talking about the Morphy Richards BRITA Filter Electric Kettle, an affordable and well-reviewed kettle that, as the name suggests, has a BRITA filter to remove minerals like lime and metals from your water. This will improve the lifespan of your kettle, making for a more cost-efficient purchase.
By buying this option, you won’t only be saving money but time since it also boils and filters the water at the same time. After it has seen a lot of use, the kettle will notify you when its cartridge needs replacing via an easy to understand electronic memo panel. Extra filter cartridges can be purchased along with the kettle on the listing page, too, so you can stock up if you anticipate a lot of use with your purchase.
Since this is a kettle with an opaque casing, it features a water gauge that allows you to see how much water is in the kettle, and it reports that water capacity in cups instead of bland millilitre measurements. It’s not illuminated, however, and whilst the gauge doesn’t need to be, it’s a staple with many kettles and is expected with them.
Also, the lid needs to get lifted up manually since it’s not spring-loaded, and this can make it harder to open, especially if your grip is weaker than the average person’s grip.
This kettle has a BRITA filter that removes limescale and metals from your water.
Simultaneous filter and boil tech will save you time.
This kettle tells you when it’s cartridge needs changing.
Handy water gauge lets you measure water content as you pour.
You have to manually pull the lid up, which can get tiresome.
That water gauge doesn’t light up, which disappointed some.
It may not be often that you sit down and think about what goes into making a kettle, and so what makes one kettle better than another. This can get even more complicated when you’re considering a specific use for that kettle, like the purging of lime and other minerals from your water.
For the purpose of this buyers’ guide, we have separated kettle properties into three broader categories, the water filtration system, the kettle body features, and the kettle base features.
Water Filtration System
Given why we’re buying these kettles, it’s no surprise that you should be focusing on the water filtration system for these products. You should be looking for filters from proven brands, with ones like BRITA featuring prominently in the list above, so you can be sure that they’ll work well.
The best kettles will be able to filter and boil the water all at once, making it as simple and convenient as using a kettle without an in-built filtration system. You want the filter cartridges to be easy to remove and clean, so you can re-use them and, when they’ve gone past their prime, should also support replaceable filter cartridges.
Some kettles will often have small panels or lights that’ll tell you when your filters should be replaced, allowing you to be on top of your water filtration duties.
As for the rest of the kettle, the body is the first thing most notice. Usually this is on a superficial level, such as whether the jug is made from glass or plastic, with plastic breaking down over time and giving water a plastic-y taste. We prefer glass or other glass-like materials in combination with stainless steel, since these reduce the growth of limescale well by resisting scratches that they could accrue.
You also might want to consider the litre capacity, with most being between one whole litre to one point eight litres. We think that this isn’t so important, hence why our number one is actually the smallest in terms of litre capacity, because we understand you’re shopping for filtration ability. The same can be said for the element wattage of your kettle, which will usually have an effect on the boiling time of your kettles.
If your kettle body is opaque, then you should want a water window and gauge that’ll help you to see the water level inside, with the gauge showing you how much there is in millilitres, litres, or, if your kettle is fancy, cups. This isn’t a big consideration with a transparent kettle, of course, though you should still want a water gauge that’s easy to read against the glass. LEDs lights are also preferable since they’ll make it easy to see when the kettle is on, something that’s great for children or others who may have trouble discerning if the kettle is hot or not.
At the top of your kettle, you can also get a specially designed spout that reduces splashback, keeping your hands safe and making sure that no water is wasted.
There are a number of features to look out for with the base of your kettle, too, the most obvious being non-slip feet or a secured underside so that your kettle doesn’t slip and slide over the countertop when you try to move it, helping you to avoid disastrous spills.
You should also want a kettle that can rotate 360 degrees on its base, especially if there’s a mix of right and left-handed people in your household. A rotating base makes it easier for both to grab and lift this kettle without incident.
Another handy feature to look for on your kettle is the ability to wrap any additional cord around the base in a way that doesn’t obstruct it, keeping your loose wiring minimal and so minimising the chance that they’ll pull the kettle over.
