Russell Hobb's range of kettles with BRITA Filtration built-in will ensure you get the best-tasting brew with zero limescale.

On top of that, it also has a built-in indicator that lets you know when the cartridge needs changing and rapid boil too. All for under £50 - we love a bargain.

A customer commented: "I bought this kettle as the limescale in my area where I live is horrendous! Best decision I ever made! Cups of tea are so much better and taste miles better than they did before!" Tried and tested by someone who lives in a hard water area, this kettle has been put through rigorous testing - and has faced pesky limescale head-on. And, most reviews agree.

Though not the most stylish pick of the bunch, this Russell Hobbs Brita Purity Filter Clear Plastic Kettle 22851 is undeniably great value, with great-tasting water guaranteed. What's not to love?

This Russell Hobbs 20760-10 Brita Purify Kettle is much the same as the Russell Hobbs Brita Purity Filter Clear Plastic Kettle, the difference being it's made of glass instead of plastic with a built-in Brita filter. It's the purest material for a kettle (it doesn't release any metals) and is even easier to clean.

A customer commented: "I love this kettle because it makes my tea taste great, which living in a hard water area. They add that not having to "constantly fill the water [filter] jug" is a huge plus - and cuts out the middle man. And, despite that, this kettle is still fairly priced. You will need to change the filter a few times and a descale now and again, but with some de-scaling care, it will serve you well.

Though a little more expensive and heavier than the previous model, it definitely has its perks. For example, this kettle also has a rapid boil, a concealed heating element, and a BRITA filter system.


  • Filters and boils simultaneously
  • Quiet, stylish and boils quickly
  • Delivers great-tasting water


  • It has the same small capacity, but there is the extra need to be more careful with glass!

Best kettle for large capacity

While this isn't technically a kettle, it's the best way to achieve the same great filtration as the Russell Hobb filter kettles but with a better capacity. It has a huge 1.8-litre capacity to hold enough water for seven to nine cups and has variable dispense, so it can auto-switch off if you're busy preparing other drinks. It has the BRITA filter technology and the bonus of a permanent limescale filter built-in, too.

A customer commented that this dispenser is a "game-changer" to their routine, with the promise of "unparalleled convenience and energy efficiency." Fast-boiling, you spend less time waiting at the kettle, hoping it boils quicker. 50 seconds is not a long time to wait - and "is particularly handy for those busy mornings". Though pricey, this dispenser strikes "a balance between practicality and efficiency", making the Breville BRITA HotCup Hot Water Dispenser ideal for households, or offices.

Perfect for tea or coffee lovers looking for a quick caffeine fix, this hot water dispenser is designed to deliver a hot cup of water in under 50 seconds. It speeds everything up - and no limescale, either.

A customer commented that they've always "struggled with hard water and limescale build-up."

Thanks to the filter, there's no lime grittiness at the bottom of your mug. Plus, the glass aspect of the little means you can keep a closer eye on lime build-up, which is a helpful feature. It takes out the guesswork - and ensures you're cleaning only when necessary. No wasted time, here.

They add: "I definitely wouldn't go back to a 'normal' kettle now. Glass is the way forward."

This model's limescale filter improves the quality of your drinks, which is ideal for hard water areas.

Russell Hobbs Inspire Electric KettleCredit: Amazon

The easy-view water window of this Russell Hobbs 24361 Inspire Electric Fast Boil Kettle with boil illumination will help you hit the right mark, which is great for energy efficiency, too. The kettle includes a removable limescale filter and concealed heating element inside its sleek accented design.

A customer commented that they have "tried and tested many kettles over the past couple of years" Living in a hard water area, you may be used to limescale. This particular user double-filters the cold water before putting it in the kettle - as limescale is a problem. However, the kettle is easy to "clean inside and out" with a great handle for easy grip - which is ideal if you struggle with holding things.

What to look for in the best kettles for hard water


Filtration is important for stopping any limescale residue from entering your drink — no one likes to see those flakes floating in your tea or coffee! There are two key filtration methods available: reusable mesh filters and cartridge filter technology.

Reusable, mesh, anti-limescale filters are the most cost-effective option. The filter sits near the spout and stops the limescale from escaping. It can be removed, cleaned, and reused with any build-up.

Cartridge filter technology is more advanced and works to eliminate the build-up of limescale in the kettle, too, as it'll filter and boil at the same time. This option is great if you prefer the taste of soft water, filtered water in general, or are looking for crystal clear water that is cleansed of any impurities.

Hannah at Russell Hobbs says that a filter cartridge "helps to reduce limescale build-up to ensure cleaner, clearer and better tasting tea and coffee".

While you may be guaranteed a cleaner, clearer cuppa, it's worth considering that the cartridges will come with a higher cost for replacement and the built-in filtration system will reduce the water capacity of your kettle. You're likely to get fewer cups out of one boil, which might mean running the kettle multiple times for larger, tea-loving families.

Concealed heating element

Having an exposed heating element in the body of your kettle can make cleaning it more difficult as you'll have to try to navigate around it to remove limescale residue. As the heating element isn't removable, this could be a tricky job for any super stubborn limescale. An exposed heating element is also likely to collect limescale easily, which can increase the build-up of limescale residue in your kettle.

By choosing a kettle with a hidden heating element, the residue won't have extra components to grip, helping to reduce any build-up.

Electric kettle

Electric kettles typically boil quicker than stove-top kettles, which gives the limescale less opportunity to form. We've also found that in a lot of anti-limescale electric kettles, they'll come with a quick boil to help reduce this further, as well as deliver your cup of tea or coffee in no time at all! If you're after a quiet kettle, an electric kettle is the best for this. Plus, you can normally get an electric kettle, and toaster setsthat look the same and match the rest of your kitchen.

We’ve listed some great kettles you can buy with a mix of filtration options to suit your budgets and needs.

What is hard water?

Sixty per cent of the UK has hard water, but what exactly is it?

Hard water is water that has "trickled through layers of limestone, chalk or rock underground", says Wessex Water. Consequently, the water has a "high mineral content" with plenty of calcium and magnesium. If you see chalky residue in your coffee cup, it's likely to be limescale.

In comparison, soft water doesn't have these collected minerals as the water has percolated through less porous, metamorphic rocks without dissolving the chemical compounds.

Though known to contribute to bone health, hard water does come with a few problems, namely it can cause a build-up of limescale on taps, shower heads and other appliances.

You're more likely to find soft water in Scotland, Wales, and Northern Ireland, as well as hard water across the UK, especially in the southeast of England.

Check your water hardness with Wessex Water's Postcode Checker.

Is it safe to use a kettle with limescale?

Yes, it's perfectly safe for you, and in fact, research suggests that it could be good for you with the heightened mineral levels helping to fulfil your calcium and magnesium intake. Good levels of calcium can help promote strong bones, regulate muscle contractions and make sure your blood clots normally.

While it might be safe for you, it isn't such good news for your kettle. Limescale build-up can reduce the lifespan of your kettle, which is why it's important to clean and descale regularly to get the most from your appliance.

How do I reduce water hardness?

There are a few ways to soften water for the longevity of your appliances, says Wessex Water:

Install a domestic water softener to your home using an approved supplier. Traditionally, water softeners use salt blocks to exchange hard water's calcium and magnesium for sodium (salt). But, your kitchen tap should be left unsoftened, says Wessex Water, for drinking and food prep.

Water conditioners "alter the nature of the hardness minerals which form hard scale when the water is heated". Conditioners don't change the chemical content of the water, unlike water softeners, but they reduce visible limescale build-up in your home with a temporary fix.

How to clean your kettle?

Removing limescale from your kettle will ensure your kettle's longevity and performance, says Hannah at Russell Hobbs. After all, limescale can actually impact your bills by reducing its energy efficiency. Plus, limescale makes your kettle noisier as the rougher surface "will increase the ‘bubble popping’ that you hear during boiling," she adds. So, what can we do to prevent it?

Well, Hannah recommends cleaning your kettle at least once a month to reduce build-up. Your purchase should have an anti-scale filter, which will "help prevent limescale deposits from pouring into your cup or pan". As effective as these are, they won't prevent build-up.

Regularly descale your kettle - to keep your kettle at its best.

Hannah recommends Russell Hobbs' Descaler, which is safe to use with kettles and coffee machines. Without a descaler, limescale could "shorten the life of your appliance" - so, it's important to take ten minutes to save money. They recommend mixing a descaler with water in your kettle, allowing it to boil. Let it sit for a few minutes, empty and rinse twice - so easy.

Or, why not try a homemade mixture of white vinegar and water? Nick Small, small appliances expert at AO.com suggests leaving "the mixture in the kettle overnight, empty in the morning, and pop on a full kettle of water, bringing it to a boil and then emptying it again”.

To de-scale your kettle with safe, natural ingredients that are super low cost, follow the advice in this video on how to clean a kettle, and it'll be sparkling again in no time.
