Water Filter Cartridge Buyer’s Guide

Cartridges are used in water filtration jugs to clean and purify your water. While filter jugs tend to last a long time, the filters can get clogged up with impurities, meaning they need replacing very regularly.

Often available in multi packs, replacement water filter cartridges are easy to find. Finding the right one for your water filter jug however, is not so easy. Not sure what to look for when it comes to the best water filter cartridge? Check out this buyer’s guide.

Certification

For safety and guarantee of quality, look for a certified cartridge. Those from reputable brands should be fully certified, but if you’re buying unbranded cartridges, double check the certification.

Ease of Use

Most water filter cartridges should be easy to use and replace. Ensure you purchase the correct cartridge for your jug, and you should find it easy to insert and remove.

Efficiency

Cartridges come with various filter systems, often a 3 or 5 step filtration. Those with an upper net, activated carbon layer and ion exchange layer tend to be the most efficient.

Most filters need replacing after around a month, so purchasing a multi pack is most economical.

Water Filter Cartridge FAQ

What is in a water filter cartridge and how does it work?

Filter cartridges usually contain activated carbon which attracts and holds onto chemical impurities. They also have very small mesh layers that filter impurities like a sieve. Ion exchange filters use filter beads to split and attract compounds. The result is fresher, cleaner and healthier drinking water.

How long does a water filter cartridge last?

Most manufacturers recommend replacing the water filter cartridge after 30 days. This will depend on how often you use your filter jug, as some cartridges have a lifespan of 100-200L.

How to change a water filter cartridge

To change a water filter cartridge you should first clean your new filter with cold water for a few seconds. Remove the old filter then insert the new one into the filter cage and push down until it clicks. Fill the jug with tap water, allow it to filter through and then discard. Do this for the next 3 jugs of water, then your filter should be ready to use.

Conclusion

Water filter cartridges need regular replacing, so finding the best one for your jug is essential. Once you’ve found your preferred filter cartridge, you can usually purchase it in a 12 or 24 month supply. For their highly efficient carbon pearl filtering system, wide compatibility and 4 week lifespan, it’s the BRITA MAXTRA+ Water Filter Cartridges that claim our top spot.
