About This

• NSF/ANSI 177 & 372 VERIFIED COMPLIANT – 99% chlorine reduction with lead-free materials; rigorously tested by 3rd party lab for safe, reliable filtration. Engineered for both hot and cold water, nearly zero pressure drop, anti-impact heavy duty ABS structure
• WHY YOU NEED A SHOWER FILTER? – Unfiltered water exposes skin and hair to chlorine, heavy metals, and PFAS that deplete natural moisture, causing dryness, irritation, and dull, brittle hair. KLLEYNA advanced dual-stage filtration restores softness, calms scalp, and delivers smoother, shinier hair from the first use
• IMPORTANCE OF KDF55 – Removes up to 98% lead and other heavy metals (mercury, copper) via redox reaction. Reduce water hardness, preventing soap scum that clogs pores, triggers breakouts and residues on fixture. Leaves skin and hair smoother and more hydrated. Protects plumbing and simplifies cleaning. Also boosts chlorine removal and extends carbon filter life. Hardest water regions: Midwest, Southwest & parts of California
• SPEED, COST, AND SCARCITY – WHY ACF STANDS APART: Activated Carbon Fiber (ACF) outperforms granular carbon by a huge margin–with adsorption rates up to 1,000 times faster and far greater capacity, thanks to its open-surface micro-pores. But this efficiency comes at a price–often 10~20X more expensive. It delivers 99% chlorine reduction and removes up to 86% of PFAS (PFOA/PFOS 86%, PFBA 69%), with a service life of up to 8,000 gallons treated
• 100% REAL MEDIA – Don't be fooled by filters with useless "filler" balls—ours uses only three proven technologies. Traditional filters use thin layers; our formula combines 1.5oz Carbon Fiber for chlorine, 0.9oz KDF55 for heavy metals, and a dense 2.6oz 1µm cotton core that traps sediments, rust, particulates, and micro-plastics. Every gram works; no space wasted. Low-density alternatives mean weaker filtration and shorter lifespan. Our cartridge is 100% active media, last longer, less replacements
• CLEAR VIEW, SMART REPLACEMENT – With transparent housing, you can easily check filter condition at a glance. Typically, the sediment filter needs replacement every 1–3 months (change when it turns deep brown), while the carbon filter lasts 3–6 months (replace when pressure drops significantly or an odor occurs). Based on real using conditions, actual lifespan varies with local water quality and usage—heavier use or poorer water may shorten the cycle. Both filters can be replaced individually or as a full set to help save costs
• 2-MINUTE UPGRADE, UNIVERSAL FIT – Tool free, no plumber, no hassle. Simply unscrew your shower head, snap the filter in place, and reattach. Universal G1/2 connector works seamlessly with handheld, rain, and combo systems. Included plumber's tape ensures a drip-free seal, while the premium gift-ready box makes it an ideal present for healthier skin and hair
