Catches rust, sand and pipe debris before water reaches your skin. Melt-blown PP pre-filter in sealed full-flow housing - all water passes through the media, with no designed bypass. Lasts approximately 2 months, replace as a 3-pack.
Ascorbic acid reacts with chlorine on direct contact - a fast redox reaction that accelerates at warm shower temperatures, and reacts with calcium and magnesium so hard water stops drying out skin and hair. Lasts 2-4 weeks with a visible end-of-life as the gel is consumed.

I installed the Pikiniki Sediment Handle Filter on my shower and the difference is immediate.
The water is visibly clearer, with no residue or traces of rust.
My skin feels a lot less tight and my hair has been softer since installation.
The installation is very simple (a few minutes), without tools, and the filter is easy to change.
You really feel that the water is better filtered, especially if like me you have fairly hard water.
Very good value for money, I recommend without hesitation.
One should last you for several months so this is a great buy
Amazing, see on video how it looks like after using it one month
Dirt is visibly filtered but unfortunately hardly any lime.
We've had the unit for a few weeks now. The head could be wider and I haven't noticed an improvement in the lime scale in the shower but my skin and hair feel much better and softer and a lot less itchy so that gets 5 stars.

P&K Skin Clinical Research Centre. Primary Skin Irritation Test. Seoul, Korea. 2023.
Independent open-label, single-arm 24-hour patch test on Vitamin C filter material. n=30 (28F/2M, mean age 47.2 years). Skin Irritation Index 0.03 (range 0.00-0.25 = non-irritant). Zero adverse events. Frosch and Kligman + CTFA + Draize protocols, COLIPA Walker 1996 guideline. Sample size and design are appropriate for a tolerability/irritation screen, not a clinical efficacy trial.

Manufacturing-partner management-system certifications. Initial issue 2025-09-16, valid through 2028-09-15. Scope: showerhead and water filter.
Korea Environment and Water Works Institute (KEWI). Residual Chlorine Removal Test. Seoul, Korea. 2020.
100 L synthetic water at 0.19 mg/L free residual chlorine, passed through Vitamin Filter. Outlet: not detected. Flow 2.52 L/min. T = 21-23 degrees C.
Note: real shower conditions are typically higher pressure and warmer than this laboratory test. The Vitamin C gel cartridge is engineered as a self-regulating system: higher pressure releases more Vitamin C from the gel matrix, and higher temperature accelerates the chlorine-neutralisation reaction. Under typical shower conditions these dynamics are expected to keep real-use performance broadly comparable to the laboratory result.
Korea Testing and Research Institute (KTR). pH-Neutralization Performance Test. Gyeonggi-do, Korea. 2023.
Alkaline test water (NaOH-adjusted to pH 9.0 and pH 10.0) passed through Vitamin C + shower filter combination at 7.5 L/min. Results: pH 9.0 to 6.45; pH 10.0 to 7.38. Test period 2022-12-02 to 2022-12-20.
