Zip Hydrotap Limescale Prevention Filter Kit for Home

(Replaces the old Zip Water filter kits models: FL170KIT, FL250KIT)

The Zip disposable limescale filters are designed to eliminate water hardness, featuring a 0.5µm filtration stage utilising carbon block technology infused with silver ions. These filters enhance water quality by:

• Eliminating carbonate-derived hardness that leads to scale formation.
• Minimizing cloudiness, organic impurities, taste, odor, and chlorine residue in drinking water.

They safeguard your appliance against mineral deposits and water-related damage. Employing Zip disposable limescale filter cartridges can effectively decrease limescale buildup in any boiling water appliance.

 Filters & CO2

To guarantee that your HydroTap delivers pure-tasting, crystal clear water throughout its life, you’ll need to ensure the filter is replaced on an annual basis. Your Zip HydroTap will notify you when the filter replacement is due. The change filter light will flash white once per minute until the filter has been replaced, and the filter percentage will show 0% on the home screen of your command centre.

If you own a Zip product that dispenses sparkling water, you will also need to replace the CO2 canister when it runs out. You can purchase these here.

Step-by-Step: How to Replace the Zip 95591 Filter

Step 1: Prepare for the filter change

• Get your new genuine Zip 95591 filter kit.

• Grab a bucket/container to catch any water.

• Place a towel beneath the filter area.

• Recommended: wear gloves to avoid touching the O-rings.

• Write today’s date on the new filter label.

Step 2: Isolate the water and remove the old filter

• On the HydroTap touchscreen, go to:
  Menu → Install → Filter Flush
  (This isolates the water supply.)

• Open the filter access door.

• Pull out the filter flush hose and place it inside your bucket.

• Open the stopcock lever on the hose to relieve pressure, then close it.

• Remove the old filter:

  • Turn it ¼ turn left (anti-clockwise)

  • Pull straight down

• Mop up any small spills.

Step 3: Install the new Zip filter

• Remove the sanitary cap from the new filter cartridge.

• Avoid touching the filter opening or O-rings.

• Push the filter up into the filter head.

• Rotate ¼ turn right (clockwise) until it fully locks into place.

Step 4: Flush the new filter

• Keep the flush hose in the bucket.

• On the screen, press Start to begin the filter flush.

• Allow at least 10 litres of water to run through the new filter.

• Press Stop once flushing is complete.

• Turn off the stopcock.

• Close the access door.

Step 5: Reset the filter counter

On the HydroTap screen, navigate to:
Menu → Filter Reset → Reset Internal Filter

This tells your HydroTap a new filter has been installed and resets the life counter to 100%.
