PRODUCT DETAILS

Matching shower filter replacement cartridge for HammerHead Showers Inline Shower Head Filter.

Tired of those filters with "12 stages" that claim a lot but don't do a thing to improve your water quality?

The HammerHead Showers Shower Head Filter is packed with the highest quality filtration media, including a proprietary blend of KDF 55 and Calcium Sulfite, the two most effective types of filtration media for shower head filters. 

When it comes to shower filtration, it's all about the quality of the materials and the surface area covered — not how many stages there are. That's why we have locked in on these two chlorine-killers and customized the size of both the KDF and Calcium Sulfite to maximize surface area without compromising your shower head pressure.

HammerHead Showers filters have been 3rd party tested to effectively reduce chlorine and heavy metals so you get cleaner water in your shower, making your skin, hair and nails smoother than ever before!

Product features:

  • Proprietary formulation contains over 450 grams of KDF 55 and Calcium Sulfite
  • 3rd Party Lab Tested to effectively remove chlorine and heavy metals for a healthier shower
  • Filtration media is rated for a variety of both hot and cold temperatures
  • Compatible With HammerHead Showers HOC-INL-CH Inline Shower Head Filter
