A practical guide to choosing the right shower filter for hard water — how they work, what they remove, and which ones are worth buying in 2026.
If you live in a hard water area, the water coming out of your shower contains dissolved calcium, magnesium, chlorine, and trace metals. These cause dry skin, eczema flare-ups, dull hair, colour fading, and that "squeaky" feeling after washing.
A shower filter won't turn hard water into soft water — that requires a water softener. What it does is remove chlorine (a major skin and hair irritant) and reduce some mineral content, which makes a noticeable difference to how your skin and hair feel.
Shower filters use one or more filtration media to treat water as it passes through:
The Philips AWP1775 uses a combination of KDF and activated carbon filtration. It has a high flow rate that won't reduce your water pressure, removes up to 99% of chlorine, and reduces limescale and impurities. The cartridge lasts approximately 50,000 litres (about 6 months for an average household).

It's important to set realistic expectations:
For whole-house protection, you need a water softener or scale inhibitor. But for improving skin health and hair quality, a shower filter is an excellent, affordable first step.
