Box of 25 ceramic beads | Grey

The box of 25 grey EM ceramic beads is a practical medium-size format for everyday uses that require a little more than a standard carafe quantity. It is especially suitable for a kettle, a dishwasher, a large family carafe or several small water containers around the home. With 25 beads, you have enough flexibility to use them in one main container or distribute them between several simple routines.

Grey EM ceramic beads are used with drinkable tap water to help make it more pleasant to drink, especially when the water has a noticeable chlorine taste or odour. They are also commonly used to help limit the adhesion of limescale deposits in kettles and other water containers. They are not a water purification system and they are not a chemical descaler. They are a long-lasting, reusable accessory designed to support more sustainable everyday habits.

This product fits naturally into a zero-waste home routine: fewer plastic water bottles, fewer disposable cartridges, fewer repeated purchases and more durable objects that can be used for years. To learn more about recommended quantities, different formats and care instructions, read the Chamarrel guide to using EM ceramic beads at home.

Why choose a box of 25 ceramic beads?

The 25-bead format is ideal when you want more flexibility than a simple 15-bead carafe box. A 1-litre carafe usually requires around 15 beads, so this box allows you to use 15 beads in drinking water and keep a few extra for a reusable bottle, vase, fruit basket or small water container. It can also be used as a full 25-bead quantity in a kettle or dishwasher, depending on water hardness and household habits.

It is a balanced format: more generous than a starter box, but less bulky than a larger pack designed for a washing machine or multiple household uses. It is suitable for families, eco-conscious households and retailers who want to offer an easy-to-understand product for tap water, kettles and zero-waste living.

Recommended quantities and uses

The suggested quantities can vary depending on water hardness, the size of the container and the expected result. The following guidelines are designed to help you start easily, then adjust the number of beads if necessary.

• 1-litre carafe: around 15 beads.
• Large family carafe: 20 to 25 beads depending on volume.
• Kettle: around 25 beads, adjusted to water hardness.
• Dishwasher: around 25 beads in a cotton pouch or cutlery basket.
• Washing machine: around 50 beads, meaning two boxes of 25.
• Fruit basket: around 12 to 15 beads.

These quantities are not rigid rules. If your water is very hard or your container is larger than average, you can gradually increase the quantity. The advantage of this box is precisely its flexibility: it gives you enough beads for several everyday uses without requiring a large bulk purchase.

For tap water, carafes and reusable bottles

The best-known use for EM ceramic beads is drinking water. In a carafe, jug or reusable bottle, they are used to help improve the taste of tap water and make it more pleasant to drink. In many countries and regions, tap water is safe but can have a chlorine smell or a mineral taste that discourages people from drinking it regularly.

Before first use, rinse the beads and boil them for around 10 minutes. Allow them to cool, place them in a clean carafe and add drinkable tap water. Wait at least 30 minutes before drinking. For a more comfortable routine, prepare the carafe in the evening and leave it overnight.

Once the habit is established, simply refill the carafe during the day. This small routine can reduce plastic bottle purchases, storage space, transport and waste. It is a simple way to make tap water more attractive at home, in the office or in a shared kitchen.

For kettles and dishwashers

Grey ceramic beads are suitable for hot water uses because they are fired at high temperature. In a kettle, they are commonly used to help limit the adhesion of limescale deposits. They do not remove limescale already built up inside the appliance, but they can support a more preventive maintenance routine.

In a dishwasher, place the beads in a small cotton pouch or in the cutlery basket if they remain safely contained. Their purpose is to support the water cycle and help limit deposits as part of regular appliance care.

A simple step away from disposable plastic bottles

When a household adopts a tap water carafe, reusable bottle or water jug, plastic waste can decrease quickly. EM ceramic beads are not a miracle solution, but they can make this transition easier by making tap water more enjoyable for many users.

Reducing bottled water consumption matters because plastic packaging can break down into smaller particles and contribute to long-term pollution. To understand this issue better, read the Chamarrel article on microplastics and the hidden cost of disposable plastic. Ceramic beads help prevent waste at the source by supporting a reusable water routine.

Grey beads or pink beads: which should you choose?

Grey EM ceramic beads are the most versatile option. Because they are fired at high temperature, they are more resistant and suitable for hot water uses such as kettles. They can also be used in carafes, reusable bottles, dishwashers and washing machines when placed in an appropriate container.

Pink beads are more porous and more fragile. They are best kept for cold water use, such as carafes, jugs and reusable bottles. If you are looking for a format that can be used in several areas of the home, grey beads are the safer and more practical choice.

Chamarrel quality, origin and transparency

Chamarrel has been one of the early promoters of EM ceramic beads in France. The EM ceramics we offer are manufactured in Japan according to the work of Professor Teruo Higa. This is important in a market where products can sometimes be presented with confusing claims, such as “special carafe”, “special washing machine” or “special cooking” as if each use required a completely different ceramic material.

Our approach is simple: the EM ceramic principle remains the same; what changes is the quantity, shape and practical format. A box of 25 beads is therefore a convenient format, not a different or artificial technology. This transparency helps customers choose according to their real needs, without paying more for misleading claims.

Care and lifespan

Before first use, boil the beads for around 10 minutes, then allow them to dry or cool. Repeat this maintenance step regularly, for example once a month, or whenever the effect seems less noticeable. If deposits form on the beads, gently brush them with a small brush, a natural loofah or a soft sponge.

EM ceramic beads can last for many years, often more than 10 years, provided they are not broken or exposed to excessive mechanical wear. Avoid repeated impacts, damaged textile pouches in machines and containers where the beads cannot be easily removed for cleaning.
