What Your Cartridge Captures Over Time

Visible buildup can include rust, mineral scale, pipe debris, and sediment collected from your shower water. Many targeted contaminants are too small to see.

Replacing the cartridge every 3 months helps maintain consistent filtration performance.

    After a few weeks the improvement is easy to notice. The chlorine smell is much less noticeable by the second wash. It connected to our shower arm without an adapter. The dryness around my cheeks seems milder. I started with the one-time option and may switch to refills later. I am glad we made the switch.

    I noticed the change sooner than expected. My skin feels less tight by the second wash. The metal housing feels solid and well made. My hair has more shine and movement. I have already recommended it to a friend.

    The first thing I noticed was the lack of chlorine smell. My hair has more shine and movement after the first week. The results have been consistent.
