Frequently asked questions

Quick answers to what readers ask most about water filter jugs.

Do I need a water filter jug in the UK?
UK tap water is treated to meet drinking-water standards, so a filter jug is about taste, odour and limescale rather than safety. If you have concerns about your supply, your water company can tell you about water quality in your area.
How often should I change a BRITA MAXTRA cartridge?
BRITA advises replacing a MAXTRA cartridge about every four weeks. If your water is very hard or you use the jug heavily, you may need to change it sooner. An old cartridge filters less well, so stick to the schedule.
Does a filter jug reduce limescale?
Yes. Filter jugs such as the BRITA MAXTRA range reduce limescale and chlorine, which makes them useful in hard-water areas, where they can cut scale in kettles. They do not remove everything: for more thorough filtration you would need a plumbed-in system such as reverse osmosis.
Should I keep a filter jug in the fridge?
Yes. Keep filtered water cool, out of direct sunlight, and use it within a day or so. Check that the jug fits your fridge shelf or door before buying, especially for a larger model like the Marella XL.
Should I choose a filter jug or an under-sink filter?
A filter jug needs no installation and suits most households that want better-tasting water. An under-sink or reverse osmosis system filters more thoroughly and supplies water on tap, but it needs plumbing and fitting.
