Description
The Kiierr Purify 15 Stage Shower Filter transforms your daily routine by removing chlorine, heavy metals, sediment, and other contaminants that can dry out your skin and weaken your hair over time. It features a universal half inch thread that easily fits most standard shower heads. Whether you rent or own, it’s a simple upgrade with a big impact, no plumber or tools needed.
- Filters chlorine, heavy metals, and impurities from your water
- Supports stronger hair, smoother skin, and reduced dryness or irritation
- Perfect for all skin types, including dry and sensitive skin
- Works with both hot and cold water systems
- Universal fit with half inch thread, compatible with most shower setups
- Quick, tool free installation for a hassle free upgrade
How It Works
The Kiierr Purify Filter uses a 15-stage system to deliver cleaner, softer water that’s better for your hair and skin. It starts with stainless steel mesh and micro-porous cotton to trap sediment and rust. Layers of KDF 55, calcium sulfite, and activated carbon then remove chlorine, heavy metals, and odors. The water is further softened and enriched by negative ion balls, ceramic balls, medical stone, and mineralized balls, while magnetic energy balls and alkaline components help balance pH. A dose of vitamin C neutralizes lingering chlorine, and final filtration ensures only the purest water reaches you. The result is a noticeable difference in the way your skin and hair feel: smoother, healthier, and more hydrated.
How to Use
- Unscrew your existing shower head.
- Attach the Kiierr Purify Filter between your water pipe and shower head. The half inch universal thread fits all standard showers.
- Twist tightly by hand, no plumber or tools needed.
- Run water for 30 seconds before first use to clear out any loose carbon particles.
- Replace the filter cartridge every 3 months for best results.

How Does RadianceFlow make a difference?
Tap water is often harsh, loaded with chlorine, metals, and imbalanced pH. These hidden irritants strip natural oils, weaken your strands, and disrupt your skin’s moisture barrier. The result? Dryness, dullness, and breakouts. Your beauty deserves more than basic filtration.
What does the filter remove from my water?
The Kiierr RadianceFlow Filtration System is engineered to target the full range of hidden irritants in tap water. It reduces chlorine, heavy metals like lead and mercury, sediment, and rust, while also balancing pH and neutralizing odors. Most filters stop at chlorine, but RadianceFlow with Vitamin C + Alkaline Ion Core goes further, ensuring every drop of water that touches your skin and hair is clean, pure, and beauty-friendly.
How does it improve hair and skin health?
Unfiltered shower water is harsh. Chlorine and metals strip away natural oils, leaving skin dry, irritated, and prone to breakouts, while hair becomes brittle and dull. The Kiierr RadianceFlow neutralizes chlorine, restores water’s natural balance, and infuses it with minerals that soften and hydrate. The result is immediate: smoother skin, shinier hair, and relief from dryness and irritation. With continued use, hair feels stronger and fuller while skin looks radiant and healthy.
How often do I need to replace the filter?
For optimal performance, replace the cartridge every 3–4 months. This keeps the Vitamin C + Alkaline Ion Core active and ensures all 15 filtration stages work at their highest level. In areas with hard water or high sediment, you may need to replace it sooner. Keeping your filter fresh guarantees consistently pure water and consistently radiant results.
Is it easy to install?
Yes. The Kiierr RadianceFlow was created for simple, DIY installation. It attaches in minutes with a universal half-inch thread—no plumber, no tools, no hassle. Whether you rent or own, you can instantly upgrade your shower into a spa-level beauty treatment.
Will it work with my existing shower setup?
Almost certainly. The universal half-inch thread fits the vast majority of US showers, whether fixed or handheld. From apartments to homes, the Kiierr RadianceFlow provides a seamless, immediate upgrade without special adaptors.
Will it help with hard water issues?
Yes. While it isn’t a full softener, RadianceFlow noticeably reduces the effects of hard water. Minerals in hard water often leave behind residue that clogs pores, weighs hair down, and dulls skin. RadianceFlow reduces chlorine and metals, balances minerals, and restores pH with the Vitamin C + Alkaline Ion Core. The result: fewer breakouts, less dryness, healthier scalp comfort, and hair that feels light, smooth, and easier to manage—even in hard water regions.

Different concerns, one solution: by removing chlorine and toxins, the RadianceFlow supports healthier hair, clearer skin, & an overall fresher feel.
