A HydroTap can still dispense water when its cartridge is overdue, but that does not mean the filtration system is performing as intended. The Zip MicroPurity 93701 filter is a purpose-specific replacement cartridge for compatible Zip systems, and selecting the correct one protects both water quality expectations and the ongoing operation of a premium filtered-water unit.

For homeowners, an exact replacement means dependable drinking water without second-guessing the cartridge inside the cupboard. For offices, cafés and facilities teams, it helps maintain a consistent water service for staff and visitors while keeping scheduled maintenance straightforward. The part number matters because a filter that looks similar is not necessarily the correct filtration specification or physical fit for the system.

What the Zip MicroPurity 93701 Filter Does

The 93701 is a Zip MicroPurity 0.2 micron filter. Its fine filtration rating is central to its role: it is designed for installations that require a higher level of particulate filtration than a standard 3 micron cartridge. The filter works within the HydroTap filtration arrangement, helping to deliver clean-tasting filtered drinking water from the appliance.

Micron ratings are not interchangeable marketing labels. A 0.2 micron filtration specification is materially finer than a 3 micron specification, so the cartridge selected should reflect the requirements of the installed system and its approved filter configuration. Replacing a MicroPurity cartridge with a different filter purely because it is cheaper or immediately available can compromise the intended setup.

Water quality also depends on more than the cartridge alone. Incoming water conditions, the condition of the filter head and connections, appliance servicing, usage volume and timely replacement all affect results. A genuine, correctly specified filter is the right starting point, but it is not a substitute for maintaining the complete system.

Why Part Number 93701 Matters

HydroTap owners often know they need a new filter but are less certain about the part number. This is where checking the existing cartridge label, appliance documentation and current filter configuration is worthwhile. The Zip 93701 designation identifies the MicroPurity 0.2 micron replacement filter, rather than the broader range of Zip cartridges that may have different micron ratings and applications.

Choosing by appearance alone is risky. Cartridge dimensions, fittings and branding can look familiar across filtration products, yet the correct replacement must suit the filter head and appliance setup. Where a system has been serviced previously, the installed cartridge label is usually the most useful reference. If the label is damaged, a specialist can help confirm the appropriate part before an order is placed.

Genuine replacement components are especially relevant in high-use environments. A busy office kitchen, hospitality venue or shared commercial tenancy may rely on its HydroTap throughout the day. Using the specified cartridge supports a predictable maintenance process and avoids the inconvenience of fitting an unsuitable part during a scheduled changeover.

MicroPurity 0.2 micron versus GlobalPlus 3 Micron

Zip offers filtration options for different requirements. The GlobalPlus 3 Micron filter and MicroPurity 0.2 micron filter should not be treated as direct substitutes. Their filtration ratings indicate different levels of fine filtration, and the appropriate choice depends on the appliance configuration and water-treatment needs.

A finer rating is not automatically the right answer for every HydroTap. It may be specified for a particular setup, but the installation must support it. Conversely, fitting a coarser filter where a MicroPurity cartridge is required may not meet the filtration standard intended for that system. The safest approach is to replace like for like unless a qualified technician has assessed the installation and advised a change.

This is also why facilities managers should record the filter part number at each service. A simple maintenance record prevents guesswork when responsibility changes hands or a replacement is needed quickly.

When Should You Replace the Filter?

Filter replacement is a maintenance requirement, not something to postpone until water flow becomes noticeably poor. A cartridge may be approaching the end of its useful service life before there is an obvious change in taste, appearance or pressure. Your HydroTap filter-change notification, service schedule and appliance documentation should guide the replacement interval.

Actual cartridge life can vary. A household with light daily use will place different demands on a filter than a large workplace, and local water conditions can also influence performance. For that reason, it is sensible to follow the appliance prompt or scheduled service date rather than relying only on visual inspection.

Arrange a replacement promptly if the unit indicates a filter change is due, if water delivery has changed unexpectedly, or if the cartridge has reached its scheduled replacement date. Reduced flow can have several causes, including a saturated filter, a restriction in the water supply or an appliance issue. Replacing the filter may be part of the solution, but persistent problems should be assessed rather than repeatedly solved with new cartridges.

Buying the Right Replacement with Confidence

Before purchasing a Zip MicroPurity 93701 filter, check the information on the cartridge currently fitted and confirm that it reads 93701 or MicroPurity 0.2 micron. If the previous service invoice is available, compare the listed part number as well. This takes only a moment and can prevent the disruption of receiving a cartridge that is not suitable for your system.

For commercial sites, it is practical to keep a spare genuine filter on hand when the appliance is critical to daily operations. This is particularly useful for offices with high staff numbers, meeting rooms, reception areas and hospitality settings where filtered water is expected to be available. Store replacement cartridges in a clean, dry location and retain the packaging until installation.

Avoid purchasing a replacement solely on a broad description such as “Zip filter” or “HydroTap cartridge”. Zip systems use a range of consumables and service components. The exact part number, micron rating and compatibility details provide the certainty that a generic description cannot.

Installation and Resetting the Service Reminder

Some experienced owners replace compatible cartridges as part of routine maintenance, following the relevant Zip instructions for their appliance. The work needs to be carried out carefully: isolate the appropriate water supply where required, release and remove the old cartridge correctly, inspect the filter head and seals, fit the new filter securely, then flush the system according to the appliance instructions.

The service reminder may also need to be reset once the new cartridge is installed. Skipping the reset can leave an unnecessary service alert on the display and make future maintenance timing less reliable. If your model has a different control interface, refer to its specific operating instructions rather than assuming the reset procedure is the same across all HydroTap models.

Professional support is a sensible option when there is any uncertainty about compatibility, leakage, poor water flow or the condition of the appliance. This is particularly true for commercial installations, where a small issue can interrupt service to many people. A technician can replace the cartridge, check connections and identify whether an apparent filter issue is actually related to another component.

Keep Filtration Maintenance Simple

The best filter replacement is the one that is correctly specified, changed on schedule and supported by a clear record of what was fitted. Note the installation date, part number and next expected service date after each change. For managed properties, place this information with the appliance records so the next team member can order with confidence.
