How to Change Your Boiling Water Tap's Filter

The best water tap filter removes limescale and a bacterial filter

Learn the difference between your boiling water tap's filters and find out how to replace yours in just a few simple steps.

Your Filters

Every boiling water tap in our range is supplied with an anti-scale/carbon filter (WF100). This is designed to trap impurities and minerals from your mains feed and protect your tap’s components from limescale and other mineral deposits.

Whether you have more than one filter will depend on whether you have a 3-in-1 or 4-in-1 tap, though replacing the filter works in the same way for both:

  • 3-in-1 taps deliver filtered boiling water using the WF100 anti-scale filter
  • 4-in-1 taps deliver filtered boiling water and filtered cold water using the WF100 anti-scale filter and the WF200 anti-bacterial filter

The anti-scale filter (provided with both systems) preserves the performance of your 3-in-1 or 4-in-1 tap by preventing corrosion caused by limescale. The anti-bacterial filter (provided with only 4-in-1 systems) removes contaminants from your cold water feed.

How to Change the Filter

Both the WF100 anti-scale (which comes with all tap systems) and WF200 anti-bacterial filter (which only comes with 4-in-1 tap systems) are replaced in the same way.

  1. Turn off the isolation valve
  2. Switch the boiling water tank off at the power source
  3. Unscrew the filter cartridge with a 1/4 turn and twist the housing to remove the carbon filter from the inside. There may be a bit of water left in there so it’s best done over the sink!
  4. Take the new carbon filter out of its packaging and slide it into the housing with the hole facing upwards
  5. Screw the cartridge back into place with a 1/4 turn, making sure it’s completely locked into place
  6. Turn on the isolation valve, followed by the boiling water tank
  7. Test the tap and check for any leakages. If there is a leakage, check and tighten the connection
  8. Voila! Your filter should be back up and removing impurities instantly

Replacing the filter at regular intervals (at least every six months) will prolong the lifespan of the boiler tank and system.

Tip: The anti-scale filter is grey while the anti-bacterial filter is blue.

FAQs

How Regularly Should You Change Your Filter?

It's recommended that you change your filter every 6 months, although those living in a hard water area may need to replace it more regularly. If you notice a decrease in boiling water pressure or taste any impurities in the filtered water then it could be time to replace your filter before the recommended timeframe.

How much will it cost?

Our filters are just £29.95 - other brands may cost more. We also offer a subscription service where you will be sent a filter every 6 months for just £24.95.

Why Change Your Tap's Filter?

Keeping your tap’s filter clean and free from any impurities is essential for protecting the tap and its components from limescale and other mineral deposits. By changing your filter as part of regular maintenance you can ensure that you enjoy crystal-clear, purified boiling water on tap whenever you need it.

Forgetting to replace your boiling water tap’s filter may also void its warranty.

Is Filtered Water Better for You?

Although UK tap water is safe to drink, there's no denying that filtered water tastes better. By removing chemicals and minerals, the water becomes 'pure' and both looks and tastes great. If you're a fan of filtered water, you'll love our 4-in-1 taps. Platinum and Quantum both offer filtered cold water at the standard mains temperature, while Quantum Chilled offers it down to an ice-cold 4 degrees.
