My skin used to break out constantly, especially along my jaw and cheeks. After switching to the Kleanzy shower filter, I noticed way fewer breakouts within a few weeks — my skin just feels calmer overall.

Hard water was wrecking my curls — dry, frizzy, no definition. Since using the Kleanzy filter, my curls are noticeably softer and shinier, and there's a lot less buildup between washes.

I'd dealt with body acne on my back for years. It's not perfect, but the Kleanzy filter made a real difference — my skin cleared up a lot and stopped feeling so irritated after every shower.

My hair used to feel dry and dull no matter what products I used. After a month with the Kleanzy shower filter, it's noticeably shinier and smoother — turns out it was the water all along.

THE WATER YOU SHOWER IN MATTERS

Every shower runs directly over your skin, scalp, and hair. In many U.S. homes, that water can carry minerals, disinfectants, and pipe residue that leave your shower feeling harsher than it should.

85% Of the U.S. has hard water, meaning mineral-heavy shower water is common across the country.
64% Of your daily chlorine exposure comes from showering and its byproducts absorb through skin.
1 in 5 Americans use water treated with chloramines, a longer-lasting disinfectant used to move water through pipes.

Unfiltered water causes:

Dry, Tight Skin

Minerals and disinfectants can leave skin feeling stripped, dry, or uncomfortable after showering.

Dull, Brittle Hair

Hard water minerals like calcium and magnesium can build up on hair, making it feel rough, heavy, or harder to manage.

Weak & Thinning Hair

Hard water minerals and chlorine can leave hair feeling weaker, drier, and more prone to breakage over time.

Skin Breakouts

Mineral-heavy water can leave residue on shower glass, fixtures, skin, and hair over time.

Why Klenzy is theclear choice.

A premium shower filter made to improve the water that touches your skin, scalp, and hair every day.

My skin feels less dry

I bought this because my skin always felt tight after showering. After about a week, my skin felt calmer and less dry, especially on my arms and legs.

Good quality for the price


Feels premium and works well. I mainly bought it for the water pressure and install, and both were great.

Looks premium in the shower

The filter looks really clean and minimal. It doesn’t make the shower look bulky, and it was very easy to attach.
