FAQs About Coffee Machine Filters & Water Treatment

What does a coffee machine water filter do?

A coffee machine water filter reduces limescale-forming minerals, particles and off-flavours in your incoming water supply. This helps protect boilers, valves and group components from scale build-up, supports consistent drink quality and can reduce the risk of breakdowns caused by blocked pipes or scale-related faults.

Do I really need a coffee machine filter if my water tastes fine?

Even if your tap water tastes acceptable, it may still contain enough hardness minerals to cause scale in a coffee machine. Hot water circuits concentrate minerals over time, so a dedicated coffee machine filter is strongly recommended in most commercial installations and in many home setups, especially in medium to hard water areas.

How often should I replace my coffee machine filter?

Replacement intervals depend on the filter model, water hardness, throughput and manufacturer guidance. As a general rule, many commercial coffee machine filters are changed every 6–12 months or after a specified number of litres. Always follow the recommendations on the product page and your machine manual, and consider using a service schedule to ensure filters are not left in place for too long.

Which Brita coffee machine filter size do I need?

The right Brita Purity or Purity C Quell ST size depends on your water hardness, daily drink volumes and machine type. Smaller cartridges such as the C50 are ideal for lower-volume machines, while larger cartridges like the C300 or Quell ST 600 suit busier sites and higher consumption. If you are unsure, contact our team with your machine details and postcode so we can help you choose.

Are these coffee machine filters suitable for both home and commercial use?

Most filters in this category are designed with commercial equipment in mind, but they can also be used in suitable home or small-office machines where the fittings and flow rate are compatible. Always check your machine manufacturer’s guidance, and if you are unsure, speak to us before ordering.

Can ADS Coffee Supplies help me design a filtration package for multiple sites?

Yes. We regularly work with Coffee Shops, contract caterers, workplaces and hospitality groups to specify consistent coffee machine filters across multiple locations. We can help you match cartridge sizes to usage, advise on installation accessories and recommend a sensible replacement schedule that balances protection with cost.
