TL;DR: Shower filters can improve skin and hair by reducing chlorine, but they don’t soften water. For long-term results, consider both filtration and softening.
What Shower Filters Actually Do
Shower filters are designed to reduce chlorine, odours, and some impurities from your water — and that alone can be a relief if you’re suffering from itchy skin or brittle hair. But while they can improve how your shower feels, most don’t solve the underlying issue: hard water minerals like calcium and magnesium.
Why Your Skin and Hair Feel Dry After a Shower
It’s not just chlorine. Hard water clings to your skin and hair, leaving behind residue that blocks hydration. In regions like Sweden or the UK, this is a daily reality — and over time, it builds up.
The Limits of Most Shower Filters
- Reduce chlorine and odours — not hard water minerals
- Do not filter out iron, sulphur, or other metals
- Require frequent cartridge changes to remain effective
What to Look For in a Shower Filter
- Activated carbon and KDF media to reduce chlorine and odours
- Independent testing or real-user feedback to confirm benefits
- Filters that balance mineral content for improved skin and hair health
A Better Solution for Long-Term Relief
The Nordisk Renhet shower filter is built for European water. It reduces chlorine, balances water properties, and helps ease conditions like eczema or scalp irritation. With a lifespan of 13,000 litres, it's made to last — and refill cartridges are easy to manage or subscribe to.
FAQs
What does a shower filter remove?
Most shower filters reduce chlorine, some heavy metals, and sediments. They do not remove hardness minerals like calcium or magnesium.
Can shower filters help with eczema or dry skin?
Yes, by reducing chlorine and some irritants, users often notice calmer skin, especially those with eczema or sensitivity.
How often should I replace my shower filter cartridge?
Roughly every 6 months or after 13,000 litres — whichever comes first.
Do they reduce limescale or soften water?
No. For hard water, only a water softener will effectively remove calcium and magnesium minerals.
Do shower filters affect water pressure?
High-quality filters are pressure-optimised. If installed correctly, they shouldn’t noticeably reduce flow.
