TL;DR: Your shower water might contain chlorine, chloramines, and heavy metals. While shower filters can help, they don’t solve hard water issues. Learn what to do instead.
What’s Really In Your Water?
Municipal water is disinfected with chlorine or chloramines, but it can also contain trace heavy metals, sediment, and other impurities. When heated in a shower, some of these compounds can become airborne or absorbed through the skin.
How Do Shower Filters Work?
Shower filters use materials like activated carbon, KDF, and ceramic beads. Each plays a specific role:
- Carbon absorbs chlorine and organic compounds
- KDF neutralises heavy metals like lead and mercury
- Ceramic beads reduce sediment and balance flow
Do Shower Filters Really Work?
They help with chlorine, odours, and skin irritation. However, they don’t eliminate calcium, magnesium, or other minerals that cause hard water. If your concern is dryness or limescale, filters may only be part of the solution.
What Shower Filters Miss
- They don’t soften water (calcium & magnesium remain)
- They typically don’t remove chloramines unless labelled for it
- They do not affect water throughout your home
Choosing the Right Filter
Look for:
- Activated carbon + KDF media
- Independently reviewed filters
- Compatibility with your water source (check for hard water)
