Waterdrop WD-TS2PPCTCS 2PP+CT+CS Under-Sink Replacement Filter Pack

The Waterdrop WD-TS2PPCTCS is a set of replacement filter cartridges for an under-sink water filtration system. It is a replacement part, not a complete system: it is meant for owners of the matching Waterdrop unit who need to refresh the filters on schedule. Here is what the pack is, what each filter does and what it fits.

What it fits

Waterdrop says the pack is compatible with its Integrated DC Filtration System, models WD-TSC-W and WD-TSC-B. It is not described as fitting other brands' housings. Check your system's model number before ordering a replacement, because cartridges with similar names can differ.

What the name means

The code 2PP+CT+CS lists the filter stages in the pack:

• PP (polypropylene) sediment filter: a pre-filter. Waterdrop says it reduces sand, rust, particulates and suspended solids, and lasts about six months.
• CT (carbon block) filter: Waterdrop says it reduces most chlorine, taste and odour, and gives about 12 months of use. Carbon block filters typically work by adsorption, in which some compounds stick to the carbon's surface as water passes through.
• CS filter: described as reducing larger particles and most chlorine, taste and odour.

The listing refers to a "double Carbon Block Filter", with each filter giving 12 months. Pre-filters tend to be changed more often because they catch the larger particles first, which protects the finer filters after them.

Service life

The brand's figures are six months for the pre-sediment filter and 12 months for each carbon block filter. These are estimates. In practice, how long a cartridge lasts depends on your water quality and how much you use. If the flow rate noticeably drops, or the taste changes, many manufacturers recommend changing earlier than the stated interval.

Changing the filters

Waterdrop says replacement takes about three seconds with a single twist and needs no tools. Even so, it is a good idea to turn off the water supply, release pressure and follow the manual's steps. After installing new cartridges, run water through the system for the period the manual recommends to flush the filters.

Size

Each cartridge measures about 3.3 x 3.3 x 10.6 inches. Make sure there's enough space below the housing to lift the old filter out and fit the new one.

Who it suits

It suits owners of a Waterdrop WD-TSC system who want to keep to the maker's replacement schedule. It is not for people who have a different system, or who want a first-time filtration setup.

What to check before you buy

• Model match: confirm your system is a WD-TSC-W or WD-TSC-B.
• What's in the pack: check the cartridge count and types against your system's stages.
• Schedule: note the install date and set reminders for the six- and 12-month changes.
• Water quality: a filter reduces certain substances; it does not treat everything. For specific concerns, look for the certifications on the product page and consider a water test.
• Space: check the clearance under the sink.
• Flushing: follow the manual for the first use.

The short version

• A replacement filter pack for Waterdrop WD-TSC-W and WD-TSC-B under-sink systems.
• Contains PP sediment, carbon block and CS filters.
• Brand-stated life: about six months for the pre-filter, 12 months for the carbon filters.
• Twist-on fitting with no tools, according to Waterdrop.
• Check your model number before ordering.
