This is a genuine BRITA replacement filter cartridge for the Purity Steam 1200 water filtration system, compatible with the CU279 head unit. It is designed to be swapped out at the end of its service life to maintain consistent filtration performance, ensuring the system continues to treat incoming water before it reaches steam-generating equipment such as combi ovens and steamers.

In a working commercial kitchen, water quality has a direct bearing on equipment longevity and food quality. Hard water deposits limescale inside boilers, heat exchangers, and steam generators, reducing efficiency over time and increasing the risk of component failure. The Purity Steam 1200 cartridge works by reducing calcium and magnesium hardness, as well as other impurities including lead and copper, before they reach sensitive equipment internals. Keeping the cartridge changed on schedule is what maintains that protection — a spent cartridge offers little meaningful filtration.

From an operational standpoint, consistent cartridge replacement supports:

Reduced limescale accumulation inside steam-generating equipment
More consistent steam quality, which can affect cooking results in steamers and combi ovens
Lower risk of unplanned equipment downtime caused by scale-related faults
Reduced frequency of descaling maintenance on connected appliances
Protection for equipment warranties that require filtered water supply

Cartridge change intervals depend on local water hardness and the volume of water processed. In areas with particularly hard water, replacements will be needed more frequently than in softer water regions. It is worth checking the water hardness in your area and cross-referencing with the Purity Steam system's capacity guidance to plan a realistic replacement schedule.

This cartridge is suited to any site already running the BRITA Purity Steam CU279 head unit — whether that is a hotel kitchen, contract catering operation, or a restaurant relying heavily on combi oven cookery. It is not a standalone filtration solution and requires the compatible housing to function.

If you are unsure about your current water hardness, replacement interval, or whether this cartridge is the right specification for your setup, the team is happy to help you work through it before you order.

Frequently asked questions

How often should the Purity Steam 1200 cartridge be replaced?

Replacement interval depends on your local water hardness and the volume of water your equipment processes. In harder water areas, cartridges will exhaust their capacity more quickly. BRITA's guidance for the Purity Steam system provides capacity figures in litres, and cross-referencing these with your water hardness reading will give you a realistic change schedule — your water supplier can confirm local hardness levels if you are unsure.

Will this cartridge fit any BRITA Purity Steam filter head?

This cartridge is specified for the BRITA Purity Steam CU279 head unit. BRITA produces different Purity Steam cartridge sizes for different capacity heads, so it is important to confirm your head unit model before ordering to ensure compatibility. If you are not certain which head unit you have installed, the team can help you identify it.

Does filtered water make a noticeable difference to cooking equipment performance?

In areas with hard water, yes — limescale accumulation inside boilers, steam generators, and heat exchangers reduces efficiency over time and can lead to component failure or unplanned downtime. Consistent filtration slows that accumulation significantly. The difference is most apparent in combi ovens and steamers that generate steam continuously during service, where scale builds up faster than in intermittent-use equipment.
