Every day, millions of people drink tap water thinking it's perfectly safe. Yet even water declared safe to drink can contain substances you wouldn't want in your body.
Tap water: safe to drink doesn't mean pure
Potability standards set maximum tolerance thresholds for dozens of contaminants — they don't guarantee water free from all undesirable substances. Between the treatment plant and your glass, water travels through kilometres of pipes that can introduce:
- Heavy metals (lead, copper, cadmium) from old pipes
- Chlorine and its disinfection by-products
- Microplastics now present in all water sources
- Pharmaceutical residues (hormones, antibiotics) that treatment plants don't filter out
- PFAS (forever chemicals) resistant to degradation
The concrete benefits of purification
Installing a gravity purification system like Pure Filters means choosing truly clean water — without compromise.
Protected health
Coldstream FTO+ filters effectively eliminate bacteria, viruses, heavy metals and chemical residues — with performance tested by ISO/IEC 17025 accredited laboratories. Results vary by contaminant; see detailed test results →
Incomparable taste
No more chlorine taste. Purified water reveals its true flavour: fresh, light, pleasant to drink every day.
Zero plastic waste
One Pure Filters filter replaces thousands of plastic bottles. A simple action with a major environmental impact.
Economical
Only CHF 0.06 per litre of purified water. Cheaper than bottled water, without the hassle of transport or storage.
Gravity purification: simple and effective
Pure Filters systems work without electricity, without pressure, without complex installation. The principle is ancient, the technology is ultra-modern:
- Pour your water (from the tap, a spring, a stream) into the upper tank
- The water passes through the Coldstream FTO+ filters by gravity
- It comes out purified in the lower tank, ready to drink immediately
No complex maintenance: filters are replaced every 6 months and purify up to 1,500 litres per pair.
Who is purification for?
Water purification is not only for high-risk regions. It also concerns:
- Families concerned about the health of their children
- Sensitive people (pregnant women, the elderly, immunocompromised)
- Travellers and adventurers who want to drink anywhere
- Environmentalists committed against single-use plastic
- Anyone who simply wants to drink better every day
Conclusion: pure water, a lifestyle choice
Purifying your water means taking back control over what you consume every day. With Pure Filters, you choose water you can see, smell and taste — truly clean.
