Waterdrop TS2PPCTUF Replacement Filter Pack for TSU, 4 Filters, 0.01 μm Reduction

If you maintain a Waterdrop under-sink ultra-filtration system, this replacement pack brings together the filters needed for ongoing service. It contains two TSPP filters, one TSUF filter, and one TSCT filter, with components designed to reduce sediment, chlorine, taste and odor, and contaminants larger than 0.01 μm.

The pack is compatible with the Waterdrop WD-TSU-B and WD-TSU-W under-sink ultra-filtration systems. Its twist-to-replace design lets you change a filter without tools, making routine upkeep straightforward.

Key takeaways

This four-filter set is organized for different replacement intervals: the pre-sediment filter provides up to 6 months of use, the carbon block filter up to 12 months, and the ultrafiltration filter up to 24 months. Those intervals help you plan maintenance by filter type rather than treating every cartridge as having the same service life. The pack is described as a 1-year replacement set, with two TSPP filters, one TSUF filter, and one TSCT filter.

The integrated PP, UF, and CT filter design targets sand, rust, suspended solids, most chlorine, taste and odor, and contaminants larger than 0.01 μm. The filters were tested by a third-party laboratory against an NSF/ANSI standard. For households already using a compatible Waterdrop system, this set provides replacement cartridges matched to that setup rather than a standalone filtration unit.

Practical tips

Use the stated service intervals as a simple maintenance plan: replace the pre-sediment filter after 6 months, the carbon block filter after 12 months, and the ultrafiltration filter after 24 months. Since the pack includes more than one filter type, keeping track of each cartridge’s installation date can help you follow its individual schedule. These intervals refer to the respective filter types, not to a single shared replacement date for all four cartridges.

How to use it

Select the replacement cartridge that corresponds to the filter being changed in your compatible system. The filter installs with a single twist and requires no tools, so the cartridge change can be handled as part of regular system maintenance. Follow the system’s cartridge positions when replacing each filter, then use the service interval for that filter type to plan its next change.

For example, when the pre-sediment filter reaches its 6-month interval, replace that cartridge and continue tracking the carbon block and ultrafiltration filters on their separate schedules. This approach helps keep routine upkeep organized while making use of the different service lives included in the system’s filter design.

Questions before you buy

Which systems is this filter pack compatible with? It is compatible with Waterdrop WD-TSU-B and WD-TSU-W under-sink ultra-filtration systems. Match the system model before choosing replacement cartridges.

What does the filter set reduce? The PP, UF, and CT filter design reduces sand, rust, suspended solids, most chlorine, taste and odor, and contaminants larger than 0.01 μm. Third-party laboratory testing was conducted against an NSF/ANSI standard.

How often should each filter be replaced? The pre-sediment filter provides 6 months of use, the carbon block filter 12 months, and the ultrafiltration filter 24 months. Track each cartridge according to its own interval.

When it makes sense

This pack makes sense for Waterdrop WD-TSU-B or WD-TSU-W owners who want a compatible set of replacement filters for scheduled under-sink system maintenance. Its mix of cartridge types, distinct service intervals, and tool-free twist installation supports a practical replacement routine while addressing sediment, chlorine, taste and odor, and other specified contaminants.
