FAQs about BRITA filters & cartridges

General

Store your BRITA filtered water in a cool place, such as the fridge. Also, protect your BRITA product from direct sunlight to avoid algae and consume the filtered water within one day.

Your water hardness can be influenced by various factors. Information on water hardness is usually provided by the respective utility company. So you may ask there.

To get an indication by yourself:

A value > 5°dH indicates medium to hard water. Additionally, the following factors typically indicate medium/hard water:

  • Heavy occurrence of limescale deposits in household appliances and around kitchen taps and bathroom fittings.
  • Appearance of limescale spots on glasses.
  • Oily streaks or scum appearing on surface of hot drinks, especially tea.


A value < 5°dH is considered soft water. In addition to this value, the following factors can also help you to indicate soft water:

  • Your home has a plumbed in water softener.
  • Low occurrence of limescale deposits in your household appliances and around kitchen taps and bathroom fittings.

Water hardness falls into two categories: permanent hardness and temporary hardness. Permanent hardness does not influence water’s taste or how household appliances work. Temporary hardness affects the taste of food and beverages prepared with hot water. Further, it causes limescale deposits in home appliances that heat water, such as kettles, steam irons, coffee makers and washers.

By reducing water’s temporary hardness, BRITA water filter cartridges reduce taste and aroma impairing substances and limescale build-up. The result is great tasting water for hot drinks and dishes prepared with water, and less lime scale build-up in home appliances. How hard is your water? Order a free water hardness test strip to find out.

If properly stored, all original BRITA cartridges can be kept for several years. Proper storage means at temperatures between 1 °C and 50 °C, without exposure to direct sunlight or heat. The cartridge should also remain sealed in its original packaging.

Both the BRITA MAXTRA+ and BRITA MicroDisc have been designed for quick, easy installation.

BRITA MAXTRA+ water filter:

Simply fill a jug or bowl with water. Immerse the BRITA MAXTRA+ water filter in cold water and shake gently to remove any air bubbles. Insert the water filter into the jug’s funnel and run water through the filter twice. After discarding the first two litres, your BRITA water filter is ready for use.

BRITA MicroDisc:

Before using the MicroDisc for the first time, place it under running water and lightly rub both sides with your fingers for approx. 30 seconds. This effectively removes any loose carbon dust that may be present.

Yes. The contents of all BRITA water filter are food-grade quality and completely harmless, even if accidentally ingested.

No. BRITA water filters are not designed to remove fluoride. Some fluoride is naturally present in tap water, whilst some water companies add fluoride to the water. If you are concerned about the presence of fluoride in your tap water, check with your local water supplier.

Once the BRITA water filter is full it simply stops filtering. It does not leak impurities back into the filtered water. 

No. BRITA water filters which contain ion exchange resin and activated carbon reduce substances from tap water that can affect its taste and appearance. The process only partially de-mineralises water. Distilled water, in contrast, is fully de-mineralised. That’s why filtered water is not suitable for use when distilled water is required, such as car batteries.

The filtering process can cause a small increase in water's potassium level. However, one litre of BRITA filtered water contains less potassium than an apple. If you have kidney disease or watch your potassium intake for other reasons, consult your doctor before using a water filter.

All BRITA products provide high quality filtration performance while effectively reducing a number of substances that can negatively affect taste or odour such as chlorine. Additionally, BRITA water filters are easy to install, set up and store.

BRITA MAXTRA+ water filter:
The BRITA MAXTRA+ water filter provides up to four weeks and 100 litres of freshly filtered water. Its ion exchange resin reduces both carbonate hardness (limescale) and metals such as copper and lead. The activated carbon reduces substances that can impair taste, such as chlorine and chlorine compounds.

BRITA MicroDisc water filter:
The compact and powerful BRITA MicroDisc filters up to 150 litres of water and lasts for up to four weeks. The technology stops unwanted elements that impact the taste of water, such as chlorine while allowing minerals like calcium and magnesium to pass through.

Depending on which BRITA water filter system you have, BRITA METER, BRITA MEMO or BRITA Smart Light monitors your filter's performance. Please refer to the product manual for more information.

Benefits

It’s better to use BRITA filtered water over tap water in steam irons to help reduce limescale build-up. However, for most steam irons with an aluminium base, de-mineralised water is recommended for optimum performance. Filtered water is ideal for irons with a chrome plated steel base. If you are uncertain what kind of iron you have, refer to your instruction manual or contact your iron’s manufacturer.

This applies to BRITA water filters based on ion exchange resin and activated carbon, e.g. MAXTRA+ filter cartridges. 

Mains water is strictly regulated and monitored, but may contain substances that impair its taste and appearance. A BRITA water filter can reduce mains water’s:

  • carbonate hardness/limescale (calcium and magnesium ions)
  • free and bound chlorine (if present)
  • lead and copper

BRITA filtered water provides you and your family the ideal basis for aromatic hot drinks, such as coffee and tea. It’s ideal for cooking and effectively protects domestic appliances against limescale build-up.

These advantages apply to BRITA water filters based on ion exchanger and activated carbon, e.g. MAXTRA+ filter cartridges. An exception is the MicroDisc water filter, which is based on activated carbon. It has been developed as a mobile and simple solution to optimise the taste of cold water. It fits into the water filter carafe and the water filter bottles.

 

BRITA products reduce plastic waste, have a significantly lower CO2 footprint than bottled water, and thus make an important contribution to a more sustainable society. As a company we also want to make such a contribution by reducing the environmental impacts of our business activities to a minimum while we continue to develop and grow at the same time.

BRITA MAXTRA+

It's just activated carbon from the BRITA water filter. The granulated activated carbon is made of coconut shells. Like all natural products, coconut shells are subject to natural variations in product quality. Sometimes this leads to abrasion of parts of the carbon into your filtered water. Preparing your water filter as described in the product manual can help eliminate carbon dust.

Don’t worry, it’s completely normal. Whether it’s damp or dry has no effect on the water filter’s performance.

No your jug is not broken! What you can hear is the PerfectFit System within the jug, but this is nothing to worry about. The PerfectFit feature ensures that all of the tap water is reliably filtered through the filter. BRITA has improved its water filters by modifying the funnel to ensure a perfect between BRITA filter jug and cartridge.

The filter material of the MAXTRA+ water filter contains a mixture of ion exchange resins and activated carbon that has been tested to food grade quality. The ion exchange resin used reduces the carbonate hardness (limescale) and reduces metals, such as copper and lead that can occur as a result of domestic installation. The activated carbon reduces substances that may impair taste, such as chlorine and chlorine compounds.

Our German engineers always strive to find the best possible solutions and to improve our existing products. They have developed the PerfectFit System ensuring that our filters fit perfectly into our filter jugs and so filter all the tap water reliably through the filter. The water is only running through the filter jug if a BRITA MAXTRA+ filter is firmly and properly inserted.

To ensure you enjoy high quality BRITA filtered water, replace the filter cartridge at regular intervals.

The lifetime of a filter cartridge depends on the local water quality. If your mains water contains a carbonate hardness of 10 to 12°dH, the filter cartridge should be replaced after 100 litres of water. If the water is harder or consumption is greater, the lifetime of the cartridge reduces accordingly.

The cartridge should be replaced at least every four weeks.

A) you have not used an original BRITA MAXTRA+ filter

B) you have not fully inserted the MAXTRA+ filter into your water filter jug. Please press the filter down a bit more into the funnel and try again.

C) you have not prepared your MAXTRA+ cartridge as per the instructions on pack

BRITA MicroDisc

The BRITA MicroDisc uses Pure-Taste-Technology to effectively filter unwanted substances while allowing minerals to pass through.

The main ingredient of the BRITA MicroDisc is fine grained activated carbon made from natural coconut shells that contains a highly porous structure. This porous structure has a very large inner surface with millions of tiny pores that trap and lock away unwanted substances such as chlorine and other taste impairing substances, as well as micro particles (≥ 30 μm). The result is fresh and pure-tasting water.

To create the solid disc of the MicroDisc, a fleece and a small amount of a binder is required to bind the granulated activated carbon together. All ingredients of the BRITA MicroDisc have been tested to food-grade quality. 

For optimal performance and hygiene reasons we recommend to exchange your BRITA MicroDisc after four weeks. We can help remind you to exchange your MicroDisc:

For the water filter bottles, simply download the BRITA refill reminder app for your smartphone by scanning the QR code on the packaging.

For the water filter carafe, either activate the Memo on the lid of the carafe, which monitors the lifetime of the MicroDisc, or download the BRITA refill reminder app to your smartphone by scanning the QR code from the packaging.

Dispose of used MicroDiscs in your general waste. Although the BRITA MicroDisc has a high amount of biobased ingredients a small fraction is non-biobased and this is why the MicroDisc is not compostable. 

Though using the same filter, the way of filtration differs between BRITA water filter bottles and BRITA water filter carafes:

BRITA water filter carafes with gravity filtration offer generally higher contact time of impurities with the activated carbon, which increases the filter performance and lifetime. The BRITA MicroDisc lasts for up to 150 litres.

With the BRITA water filter bottles the water is being filtered while drinking. The suction leads to a higher flow rate and less contact time with the activated carbon. The BRITA MicroDisc water filter lasts for up to 60 litres.
