| Waterdrop WD-FC-01 | $20 | Replacement filters sold as a three-pack, reference WD-FF-01A. 16.2 oz (460 g). | Chlorine, taste and odor under NSF/ANSI 42, and lead, stated and tested by a third-party laboratory. The maker states it DOES NOT REDUCE TDS and names its own reverse-osmosis system instead. | ACF — activated carbon fiber — with a bypass switch between filtered and regular tap water. CERTIFIED NSF/ANSI 42 for chlorine, taste and odor, and NSF/ANSI 372 for lead-free material: one of only two listings on this shelf naming a filtration standard rather than a material standard. |
|---|
| FRIZZLIFE FF1080 | $27 | Nine supplied: 6 PP cotton and 3 carbon fiber. 14.4 oz (408 g). | 99% of chlorine, pollutants, heavy metals, tastes and odors — a single percentage covering four unlike things, on a listing that publishes no NSF 42 or 53 to back it. TDS is NOT reduced; the maker states it retains beneficial minerals. | A two-media cartridge system — PP cotton and carbon fiber — in lead-free solid brass with an ABS aerator body, on a 1080° robotic arm with rubber-sealed swivels, with two spray modes, pressurized spray and splash-proof bubble water, and a three-layer mesh to stop the faucet blocking. Certified NSF/ANSI 372 for material, plus DOE and CEC; NEITHER NSF 42 NOR NSF 53 is published. |

| Tylola TWF-01 | $30 | Five supplied. The maker advises replacing the HOUSING with all five cartridges after 8–10 months, and warns that overtightening can crack the top of the body and spray water — a cartridge change needs only the bottom unscrewed, never the top. 7.2 oz (204 g). | NONE ARE NAMED AS SUCH. The listing names the five media and leaves the reader to infer what they do, where every other filter on this shelf states at least a target. | A five-media cartridge — carbon fiber, 100% coconut shell activated carbon, KDF 55, calcium sulfite and PP cotton — in a durable ABS housing. The certification is « NSF-tested filter materials » with NO NSF STANDARD NUMBER PUBLISHED, which is a claim about the media and not about a result. |
|---|
| WINGSOL WS-FM | $30 | FIVE CARTRIDGE OPTIONS, which no other filter here offers: PAC, PC alkaline, 5-in-1 heavy metals, CRM reusable, and chloramine. 12.3 oz (350 g). | PFAS, PFOA, PFOS, chlorine, heavy metals and odor. Minerals are preserved and the maker states it cannot reduce TDS. | A cartridge filter in a seamless one-piece food-grade lead-free 304 stainless steel housing, on a 360° swivel. CERTIFIED NSF/ANSI 42 AND 53 — THE ONLY 53 ON THIS SHELF, and 53 is the health-effects standard the heavy-metal claims on this shelf otherwise rest on nothing. |
|---|
| Waterdrop WD-FC-02 | $34 | Replacements sold as a three-pack, reference B07C3LFJR2 (Ultra). 9.1 oz (259 g). | Chlorine, taste, odor and skin irritants. TDS is not reduced; the maker names its RO system instead. | 4-stage with 0.01 μm ULTRAFILTRATION — the only membrane figure on this shelf that is physically plausible — on activated carbon fiber media. Certified NSF/ANSI 372, WHICH IS MATERIAL SAFETY ONLY: neither NSF 42 nor NSF 53 is published, so the chlorine and skin-irritant claims are the maker’s own. |
|---|
| ATOJET AJ-8310C | $35 | A one-year set of six, plus the ceramic anti-scale cartridge. The published dimensions of 7.24 × 3.62 × 100 in (184 × 92 × 2540 mm) cannot describe this product — 100 in (2,540 mm) is eight feet — and are not repeated here. | Chlorine, stated to be Minimized rather than reduced by any figure, aimed at sensitive or easily irritated skin and scalp. | A 6-stage carbon composite — a sediment layer and a compressed activated carbon core — plus a CERAMIC CARTRIDGE against mineral buildup from stagnant water, in an Ecozen housing, plant-based and BPA-free, stated safe for skin. The filters are stated TESTED TO NSF/ANSI 42 STANDARDS, and ROHS; neither NSF 53 nor NSF 372 is published. |
|---|
| Filterbaby N2 Skincare Filter 2.0 | $108 | ONE SUPPLIED, for three months — the only filter on this shelf that ships with a single cartridge, where Frizzlife ships nine. | Chlorine, chloramine and « other common tap water elements », which names nothing in particular. | A carbon-fiber filter sold for SKINCARE — hydration, blemishes, clogged pores, irritation — with a single button bypassing between filtered and unfiltered water. NO NSF CERTIFICATION OF ANY KIND IS PUBLISHED, where five of the seven filters here name at least a material standard. The published filtration figure is 0.000001 mm — one nanometer — which is not a credible figure for carbon fiber, and a clinical result is stated with NO STUDY CITED. It was named one of TIME’s Best Inventions 2024. |
