A Zip 93701 filter is not a generic cartridge purchase. It is a MicroPurity 0.2 micron replacement filter designed for compatible Zip HydroTap systems, where filtration performance, fitment and the unit’s filter-monitoring function all matter. Selecting the correct genuine replacement helps keep filtered drinking water tasting clean while protecting the performance expected from a premium boiling, chilled or sparkling water system.

For homes, workplaces and hospitality settings, a HydroTap can be one of the most-used appliances in the kitchen or staff area. Replacing its filter at the right time is straightforward, but ordering by appearance alone is not enough. Confirm the part number, check your system model and use the unit’s replacement prompt as the starting point.

What is the Zip 93701 filter?

The Zip 93701 is a MicroPurity 0.2 micron filter cartridge used in selected Zip HydroTap installations. Its fine filtration media is intended to reduce very small particulate matter and support high-quality drinking water at the outlet. The 0.2 micron rating is the important distinction here: it is a specialist filtration specification, not simply a standard sediment filter.

A cartridge’s micron rating describes the size of particles it is designed to capture. A lower rating generally means finer filtration, but it does not mean every filter is interchangeable. Filter heads, electronic monitoring settings, water pressure requirements and appliance generation can differ between HydroTap models. This is why the 93701 part number should be matched to the filter currently fitted and the model details on your Zip system.

The right filter also supports the experience people expect from a HydroTap: clear-tasting chilled water, dependable boiling water and, where applicable, consistent sparkling water service. Water quality can vary considerably between properties, so a genuine filter is a practical safeguard against fitting a cartridge that does not suit the appliance.

Check Zip 93701 compatibility before ordering

Start with the label on the existing cartridge. If it shows 93701, that is the strongest reference point for a like-for-like replacement. Then check the model and serial information on the HydroTap itself, particularly if the system has been installed for several years or was inherited with a property.

It is tempting to assume that filters with similar dimensions will fit. That can create problems. An incorrect cartridge may not engage correctly with the filter head, may not be recognised by the system, or may provide a different filtration level from the one specified for the installation. In commercial environments, that uncertainty can become disruptive when a kitchen, meeting space or café service point needs to stay operational.

If you are unsure, have the following details ready before seeking advice: the filter part number, the HydroTap model, whether the unit supplies sparkling water and a clear photo of the fitted cartridge and head assembly. These details help identify whether the Zip 93701 is the correct OEM Replacement Spare Part without guesswork.

Compatibility is also worth reviewing when a system has recently been repaired. If the filter head, control board or under-bench configuration has changed, the technician may have specified a particular cartridge for the updated setup. Retaining that specification is usually the sensible choice.

Genuine replacement filters versus lookalike cartridges

A lower-priced compatible cartridge can appear attractive, especially when several filters are due across an office or multi-site property. The trade-off is certainty. Generic alternatives may use different media, sealing arrangements or flow characteristics, even when they are marketed as suitable for the same appliance.

With a genuine Zip filter, the cartridge is produced for the intended filter head and HydroTap application. That provides confidence in the physical connection and the stated MicroPurity 0.2 micron filtration specification. It also reduces the risk of an avoidable call-out caused by a leak, poor fit or an appliance fault message after replacement.

For a high-use workplace system, genuine components can be the more cost-effective option when downtime, staff inconvenience and service visits are taken into account. For a lightly used home system, the same principle applies: use the part specified for the appliance rather than treating the filter as a universal consumable.

When should a HydroTap filter be replaced?

Your HydroTap’s filter-change alert should lead the decision. Zip systems monitor filter use and will indicate when a replacement is due based on their programmed service settings. Do not wait for a noticeable change in taste before acting. By that stage, the cartridge may already have reached its recommended service point.

Actual filter life depends on water consumption and the incoming water conditions at the property. A busy office kitchen can move through its filter allowance faster than a household, while sediment or unusual water conditions may affect performance. A calendar reminder can assist with planning, but it should not override the appliance’s filter prompt or a technician’s advice.

Arrange replacement promptly if the system displays a filter warning, water flow drops noticeably, the water quality changes, or the cartridge is due under the site’s maintenance schedule. Low flow does not always mean the filter is the cause. It can also relate to inlet pressure, a blocked strainer, a valve issue or another service fault. If a new, correct filter does not resolve the issue, professional diagnosis is the better next step.

Replacing a Zip 93701 cartridge carefully

Many compatible HydroTap systems are designed to allow a filter cartridge change without removing the complete appliance. Even so, the exact process varies by model. Follow the instructions for your specific HydroTap and avoid forcing any component.

Before starting, make sure there is clear access to the under-bench unit and enough space to remove the cartridge safely. Keep a cloth nearby for residual water. Turn the cartridge only as directed by the appliance instructions, remove it carefully and check the filter head and surrounding fittings for signs of moisture, damage or worn seals.

Fit the new 93701 cartridge firmly into the correct position. Once installed, reset the filter status where required by the model and flush the system according to the manufacturer’s procedure. Flushing clears air and conditions the new media before regular drinking-water use.

After replacement, inspect the cupboard area for drips and test each available function. On a boiling and chilled unit, check both outlets. On a sparkling model, check sparkling water as well, remembering that poor carbonation is not necessarily a filter issue. It may relate to the CO₂ cylinder, regulator, settings or another component.

Do not reuse an old cartridge or try to clean it for further service. Filtration media is consumable, and an expired filter cannot be restored by rinsing. Dispose of the used cartridge in line with local waste guidance and site procedures.

When to book a technician instead

A cartridge replacement is only one part of HydroTap care. Book a specialist if the filter cannot be removed easily, the head assembly is leaking, an error message remains after reset, or water delivery is still poor with the correct new filter fitted. The same applies if the unit has not been serviced for an extended period or is due for a broader inspection.

Professional maintenance is particularly useful for commercial sites. It can combine filter replacement with checks of hoses, pressure, ventilation, pumps, chilled-water performance and, on sparkling units, the gas system. That approach is more reliable than waiting for a busy staff kitchen or customer-facing service point to fail.

KDAC Water Filtration supplies genuine Zip replacement components and can assist Sydney customers with installation, repairs and ongoing HydroTap service. For nationwide replacement-filter orders, confirming the existing part number before purchase remains the quickest way to get the correct item.

Keep the next replacement simple

Record the installation date, filter part number and the appliance model when the new cartridge is fitted. For an office, keep that information with the facilities maintenance record; for a home, a label inside the under-bench cupboard is often enough. It makes the next Zip 93701 replacement faster and helps anyone servicing the unit understand exactly what has been installed.

A correctly matched filter is a small component with a direct effect on everyday water quality and appliance reliability. Check the part number, use the specified MicroPurity 0.2 micron cartridge and act when the HydroTap tells you it is due.
