Residents of areas with hard water are all too familiar with the scourge of limescale. This mineral build-up can cause appliances to run less efficiently and even damage them over time.

So does a water filter jug remove limescale? The answer is yes, but there are several factors to consider when shopping for a filter jug.

Keep reading to learn more.

The first step to answering the question of whether a water filter jug removes limescale is determining why there is limescale in the first place.

This mineral is created by the gradual buildup of calcium carbonate over time, which eventually forms a hard layer that coats appliances and pipes.

Limescale is made of the same material as limestone, which explains why it often forms in areas with very hard water or high mineral content. It is a byproduct of calcium and magnesium content in hard water. Without these two elements, there would be no limescale.

When they come into contact with water, these minerals naturally separate from one another and become positively charged ions known as cations. As the ions travel through water, they attract the negatively charged particles of limescale and create a mineral build-up.

This is why it tends to form in appliances that use a large amount of water over a long period of time. Laundry machines, dishwashers and showers are some examples.

Water Filter Jugs and Limescale

Hard water often contains high levels of calcium and magnesium. This mineral build-up is what causes limescale, which can coat taps and appliances with unsightly deposits.

Popular methods of removing limescale include descaling agents and ion exchange filters. A popular example of an ion exchange filter is Brita’s water filtration pitchers, which use activated carbon to remove chlorine as well as heavy metals.

How do water filter jugs remove limescale?

A typical water filter jug may not be enough on its own to solve the problem of hard water.

However, there are several things that homeowners can consider when shopping for a pitcher-style or faucet-mounted system:


The amount of filtered water produced per cycle will vary from one model to another. Consider what you need before making your purchase so that you don’t find yourself constantly filling up the reservoir.

Filter Type

The type of filter used will determine how often it needs to be replaced. A sediment water filter that removes impurities may need to be changed every two months, while granulated activated carbon filters last longer but are more expensive.


Faucet-mounted models may require professional installation. Countertop filters can be installed without difficulty by homeowners or tenants, so they are a good option for renters on a budget.

The capacity of the jug you choose should also depend on how many people live in your home and their drinking habits. For example, an office building with 100 employees would have different needs than a household with four occupants.

The type of filter you choose should also consider your budget. Some types are more affordable than others, making them worth considering if saving is a priority.

Benefits of Water Filter Jugs

While it’s true that many homeowners in hard water areas may need more than a simple water filter jug, these devices still provide several benefits:

  • Clear, healthy drinking water – Tap water can contain pollutants such as heavy metals , which is why it’s important to invest in a good filtration system for your home or business. This will ensure that you get pure and clean tasting drinking and cooking water.
  • Reduced limescale – Using an ion exchange filter water jug will ensure that your appliances run as efficiently as possible. The addition of minerals such as magnesium and calcium decrease the efficiency of heating elements and boilers, so keeping these mineral levels in check is a good idea.
  • Money savings – A quality filtration system can save you up to $200 per year on your water bills by reducing impurities and limescale build-up. The cost of installing a pitcher or countertop filter depends on the type of model you choose. However, these units are relatively inexpensive.
  • Saves time – Faucet-mounted filters allow you to enjoy fresh filtered water without the need to refill the pitcher every day. These models attach directly to your faucet so that water is dispensed through the spout as normal. However, the difference is that you will now be able to enjoy water that has already gone through the filtering process.
  • Comfortable, healthy home – Hard water can leave marks in your shower and affect how your laundry looks when dried. Poor quality drinking water also leaves an unpleasant taste in the mouth, which is why investing in a good filtration system for your home makes sense if you want to maintain hygiene and comfort in your home.

How do you filter really hard water?

Water is essential for life, but it can also be a nuisance when it’s hard. Scale build-up from hard water can cause all sorts of problems, like clogging your pipes and making your fixtures look ugly.

If you have really hard water, then you need to take some extra steps to make sure it’s filtered properly.

Hard water can cause problems with sinks, toilets, tubs, and showers. While you can use vinegar to clean off the limescale build-up, it’s probably easier to install a home filtration system so that hard water never builds up in the first place.

The process of filtering water is simple, and you can use it to get rid of limescale build-up so that your fixtures look good again. There are several different types of filtration systems available, but it depends on how much you want to spend and what type will suit your needs best.

There are two ways in which hard water is filtered. Natural filtering involves passing water through layers of sand and activated charcoal. Reverse osmosis is similar in some ways, but instead of using natural filtration methods, water is passed through a membrane instead.

Reverse osmosis filters are often combined with carbon filters to produce the best possible results. The carbon filter will eliminate odors and chlorine from the tap water before it passes through the reverse osmosis membrane.

This means that you get clean drinking water while also eliminating any odd tastes or smells.
