Buying the best water filter jug

A water filter jug works by passing tap water through a filter cartridge before it reaches the jug. Depending on the type of filter, it can help reduce things that affect the taste, smell, or limescale content of the water. Many people choose water filter jugs to switch from bottled water to tap water and to improve the taste and freshness of their drinking water.

Choosing a water filter depends on how you’ll use it day to day. Think about where you will keep it, how often you’ll refill it and how easy it is to maintain.

Check the capacity 

Water filter jugs usually list two capacities: total capacity, which shows how much the jug can hold overall and filtered water capacity, which shows how much filtered water is ready to pour. A larger jug can be useful for families, shared homes or filling bottles before you head out. A smaller jug may be easier to lift, pour and store in the fridge. 

Make sure it fits your fridge

If you like chilled filtered water, check the product dimensions before you buy. Many jugs are designed to fit in fridge doors. Slimmer jugs are also a great choice if you are short on space. 

Look at cartridge compatibility

Filter cartridges are not always universal. Before choosing a jug, check which cartridges it uses and how easy they are to replace.

Choose between plastic and glass 

A BPA-free plastic water filter jug is usually light, practical and easy to move around the kitchen. A glass water filter jug can feel more suitable for serving at the table and is a good choice if you prefer glass kitchenware. 

Check the filter reminder

Some filter jugs have a manual reminder, while others include an electronic or smart indicator. This is useful if you forget when the cartridge was last changed.

Other useful features include: 

• Easy-fill lid: makes topping up quicker. 
• Comfortable handle: helpful when the jug is full. 
• Pour-through lid: useful for one-handed refilling. 
• Spout cover: helps keep dust away from the water outlet. 
• Dishwasher-safe parts: makes cleaning easier, but check which parts need hand washing. 
• Cartridge indicator: helps you keep track of filter changes.

Explore fridge-friendly jugs, glass filter jugs and replacement cartridges to keep filtered water ready at home.

The best water filter jug for you depends on your household's needs, including how much water you use, where you'll store it and how often you want to replace the cartridge. Larger jugs are ideal for families, while slim fridge-friendly designs keep chilled filtered water close at hand. If you're looking for something stylish for the dinner table, a glass water filter jug could be the perfect choice.

Most water filter jug cartridges need replacing every 4 to 8 weeks, but the exact timing depends on the brand, filter type and how much water your household uses. Some advanced cartridges can last longer, so check the manufacturer's guidance.

Changing your water filter cartridge regularly helps ensure your filtered water continues to taste fresh and the filter performs as intended. An older cartridge can become less effective over time, which may affect water taste and odour.

Many modern water filter jugs include a handy cartridge indicator that lets you know when it's time for a replacement. If yours doesn't, setting a reminder on your phone can help you stay on track.

For the best results, replace your cartridge as recommended and follow any care instructions provided with your water filter jug. This will help you enjoy clean, great-tasting filtered water every day.
