PRODUCT DETAILS
HANDHELD FILTERED SHOWER HEAD THAT MAINTAINS YOUR SHOWER HEIGHT
The HammerHead Showers Slim Inline Filter solves what other showerhead filters can't: it's a filtered shower head handheld solution that doesn't lower your shower position. Unlike bulky alternatives, this inline installation sits flush against your wall, delivering powerful chlorine removal while maintaining full water pressure.
FILTERED SHOWER HEAD FOR REMOVING TOXIC CHEMICALS
Dual-action filtration combines KDF-55 copper-zinc with calcium sulfite to remove chlorine, heavy metals, and sediment. This hand held filtered shower head uses proven technologies that transform contaminants into harmless substances—no absorption needed. The result is cleaner water from your first shower.

Filtration That Actually Performs
HammerHead®'s filters use genuine KDF-55® and calcium sulfite — proven filtration materials chosen for reducing chlorine and heavy metals in shower water. Third-party tested under NSF/ANSI 177, this focused approach outperforms multi-stage filters that rely on ineffective filler.
By reducing chlorine and other contaminants, water feels gentler on skin and hair — helping limit dryness, improve rinsing, and leave hair feeling smoother after every shower.
Each filter is designed to last up to 10,000 gallons or about 3 months of regular use (whichever comes first), delivering consistent filtration without frequent replacements.
Chlorine
A blend of KDF-55® and calcium sulfite reduces chlorine in shower water, helping limit dryness and irritation.
Heavy Metals
KDF-55® helps reduce heavy metals like lead and mercury that can affect skin and hair over time.
Bacterial Growth
KDF-55® naturally helps discourage bacteria and buildup inside the filter.
