What do our water filters contain & how do they work?
What does a water filter actually contain – and what does it do in practice?
Here’s a clear answer.
What is the filter made of?
Filtration works through a combination of materials that operate in several stages:
Activated carbon
Reduces chlorine and organic substances that affect taste and odor.
Ion exchange material
Reduces limescale in the water and helps lower metals such as lead and copper from plumbing systems.
Multi-stage filtration
The water passes through several layers that work together to reduce unwanted substances and improve overall water quality.
What is filtered out?
- Chlorine (taste and odor)
- Limescale (water hardness)
- Metals such as lead and copper
- Selected pesticides and chemical substances
- By-products from water treatment (trihalomethanes)
Minerals such as magnesium and potassium are retained.
PFAS and selected substances
The Health Expert filters are developed with a focus on reducing PFAS and similar substances by up to 92%.
The effect depends on the composition of the water and may vary from location to location.
Environment & usage
Filtering tap water instead of buying bottled water helps reduce both plastic use and transport.
- One filter purifies up to 150 liters of water
- This corresponds to approximately 100–150 plastic bottles
- Less packaging and transport result in a lower overall environmental impact
It’s a simple way to reduce unnecessary waste in everyday life.
Recycling & disposal
The filter consists of multiple materials and should be disposed of as regular household waste after use.
It cannot be recycled as plastic, but the overall environmental impact is still lower compared to single-use bottles.
Why we do this
Drinking water in the Nordics is carefully tested and monitored according to established standards.
In recent years, these standards have become stricter – including for PFAS – to further protect both human health and the environment.
At the same time, it’s not always easy to get a clear picture of what your water actually contains – such as PFAS, pesticides, and other trace substances.
That’s why we believe it makes sense to understand your local water quality and make conscious choices in everyday life.
You can usually find water quality reports for your area through your municipality or local water supplier.
