What the maker puts in writing
- “Micron filtration removes 99% chlorine, Rust etc… Lead-free brass + BPA-Free material… Certified by both the DOE, the CEC and NSF/ANSI 372. Do not reduce the TDS value because FF1080 retains beneficial minerals in water during filtration”
- “FEMALE: 55/64”(22mm (0.87 in)), G1/2(20mm (0.79 in)), M18.5. MALE: 55/64”(22mm (0.87 in)), 15/16”(24mm (0.94 in)), 13/16”, M18.5, while 15 additional thread sizes are available upon request”
- “The system includes 6 PP cotton and 3 carbon fiber filter cartridges… The replacement cycle is 30 days”
- “Connected to robotic arm for a full 1080° of rotation and extension… By adjusting the robotic arm, both the elderly, adults and children can achieve an easy and comfortable use angle”
- “Easily switch between pressurized spray and bubble water modes… patented honeycomb bubble aerator design, which effectively prevents splashing… The maximum flow rate is 1.2 gpm”
- “Made of premium lead-free brass and ABS aerator body… the aerator contains three layers of filter mesh to prevent faucet blockage”
Three dollars a month
Nine cartridges in the box. Six PP cotton, three carbon fiber, thirty days each.
Nine months of filtered water inside the $26.99.
Set against the rest of this shelf by cost per month of supply:
$2.92 — Atojet, a stated year
$3.00 — this, and the Tylola
$6.66 — Waterdrop FC-01
$10.00 — WINGSOL
$11.33 — Waterdrop FC-02
$36.00 — Filterbaby
That is the clearest arithmetic on the shelf, and it is the right one to run: the housing is bought once and the cartridges forever.
And an arm that actually moves
This is not really a filter. It is a filter, an extender and an aerator in one body.
A thousand and eighty degrees — three full turns — on a jointed arm that extends and folds, with rubber-sealed swivels.
A bathroom faucet points at one place in the middle of the bowl. This can be aimed at the back of the sink to rinse it out, down at a bucket on the floor, or turned up so a child can drink from it. The listing makes the point itself: both the elderly, adults and children can achieve an easy and comfortable use angle.
And two modes: a pressurized jet for cleaning, and an aerated bubble stream with a honeycomb plate that keeps your sleeves dry.
None of the other six filters on this shelf moves at all.
Seven threads, and fifteen more if you ask
Female 55/64 (22 mm), G1/2 (20 mm), M18.5. Male 55/64 (22 mm), 15/16 (24 mm), 13/16, M18.5.
Published to the millimeter, which is what the compatibility question on this shelf actually needs — and then an offer to send others.
With lead-free solid brass at the joint rather than plastic, which is where a rotating fitting on water pressure eventually leaks.
Now the certification, read carefully
Certified by both the DOE, the CEC and NSF/ANSI 372.
In the same bullet as removes 99% chlorine, Rust etc.
Those two claims are unrelated. NSF/ANSI 372 certifies the material is lead-free. It does not test filtration. The DOE and CEC certifications are water-efficiency programs for the aerator.
So the 99% figure has no standard behind it on this page.
The standards that would are NSF/ANSI 42 for chlorine, taste and odor — which the $19.99 Waterdrop FC-01 holds — and NSF/ANSI 53 for lead and PFAS, which only the $29.99 WINGSOL holds.
Three listings on this shelf publish 372 alone, and a buyer reading “NSF certified” will take it for a performance claim.
And the honest caveat it does publish
Do not reduce the TDS value because FF1080 retains beneficial minerals.
Which is correct, and pre-empts the complaint that follows every pocket TDS meter: the number does not move, so the filter looks useless. It removes chlorine and particles; it does not desalinate.
Four of the seven listings here say so. It is the best habit on the shelf.
No operating temperature or pressure published — where Tylola publishes 39-140 °F and 15-60 psi, and the Waterdrop FC-02 publishes a cold-water-only limit.
