The Waterdrop WD-2PPGCCT-1008 is a replacement filter set for the brand's three-stage under-sink systems, the WD-TSA and WD-TSB. It is a part, not a complete system. It is for owners who already have one of those units and want the filters to keep it running.
What is in the pack
The pack contains four cartridges: two PP filters, one GC filter and one CT filter. That covers the three stages of the system, with the first stage using the two PP filters. Waterdrop calls it a one-year combination pack.
What each filter does
- PP (polypropylene sediment filter): the first stage. This kind of filter typically catches sand, rust and other suspended particles, protecting the later stages. Waterdrop says it provides 6 months of use, which is why the pack includes two.
- GC (granular carbon): carbon media typically reduces chlorine, taste and odour. Waterdrop gives it a life of 12 months.
- CT (carbon block): a compressed carbon block, listed with a life of 18 months. Waterdrop says this filter is certified by IAPMO R&T to NSF/ANSI 42 for chlorine, taste and odour reduction and to NSF/ANSI 372 for lead-free materials.
Waterdrop says the combination reduces fluoride, chlorine, heavy metals, taste and odour, sand, rust, particulates and suspended solids. These are the brand's claims, so check the certification documents for what is verified.
How the replacement works
The cartridges twist in and out, and Waterdrop says changing one takes about three seconds. The usual routine is to shut off the water supply, relieve pressure as the manual describes, replace the cartridges, flush the system and check for leaks. The listing describes a sealed, leak-resistant design.
Timing the changes
Because the stated lives differ (6, 12 and 18 months), you will not change every cartridge at once. The pack is designed to cover a year, with the PP filters replaced twice. Real life depends on your water quality and usage, so follow the manual and note the install date.
Size and weight
The pack measures 11.1 x 17.2 x 4.3 inches (about 28 x 44 x 11 cm) and weighs 5 lb (about 2.3 kg).
Who it suits
It suits owners of a Waterdrop WD-TSA or WD-TSB system who want a complete set of genuine-branded cartridges for a year of use.
What to check before you buy
- Your system: confirm that you have a WD-TSA or WD-TSB, and match the model.
- Which filters you need: a pack with two PP, one GC and one CT may include cartridges you do not need yet.
- Date of last change: track when each stage was last replaced.
- Water quality: heavy sediment can shorten the life of the PP stage.
- Instructions: follow the manual when you flush the new filters.
