Water Filtration and Quality: What You're Really Drinking

Our Water

Tap water in Luxembourg is generally of good quality. But there’s a difference between water that’s “potable” and water that’s “pleasant to drink”: a chlorine taste, particles, and traces of metals. The filtration system in Aquavital water dispensers bridges this gap, removing what’s unpleasant and retaining what’s beneficial.

High-quality water, but there is room for improvement

Tap water

The water supplied in Luxembourg comes mainly from groundwater and surface sources (Lake Haute-Sûre). It is treated to meet the EU’s strict drinking water standards (Directive 2020/2184).

✓ Bacteriological quality in compliance with strict EU standards
✓ Essential minerals (calcium, magnesium, depending on the municipality)
! Residual chlorine, which ensures the water is safe to drink throughout the system but alters the taste
! Occasional suspended particles (sediment, residues from old pipes)
! Variable hardness (limestone content varies by area)

Multi-stage filtration

Our system

  1. Floor 01

    Pre-filtration (5 microns)

    Filters out coarse particles: sediment, pipe debris, and traces of limescale.

  2. Level 02

    Activated carbon

    The core of our filtration system (made from roasted coconut shells). Absorbs residual chlorine (90% of unpleasant tastes), volatile organic compounds, residual pesticides, and tastes and odors.

  3. Level 03

    Microfiltration (0.2 microns)

    Filters out microparticles, certain cysts, and larger bacteria. Enhanced bacteriological safety.

From the faucet to the glass, you can taste the difference

The Difference

  • The Taste Test

    The Taste Test

    In taste tests, 80 to 90 percent of participants describe the filtered water as “softer,” “more neutral,” and “more pleasant to drink.”

  • Effect on consumption

    Effect on consumption

    Average consumption per employee increases by 20 to 30 percent in the first few weeks after installation and then stabilizes at a higher level.

  • Living alongside minerals

    Living alongside minerals

    Activated carbon and microfiltration do not remove essential minerals. Filtered water remains “living” water in a nutritional sense.

Effective, Long-Lasting Filtration

Maintenance

  • Scheduled Replacement

    Scheduled Replacement

    Filters are replaced every 6 to 12 months, depending on the model and usage. Included in the plan.

  • Periodic Sanitization

    Periodic Sanitization

    Disinfect the internal system every 6 to 12 months; more frequently for healthcare, hospitality, and educational facilities.

  • Bacteriological Tests

    Bacteriological Tests

    For critical environments, a post-sanitization bacteriological analysis report is available upon request.

  • Service Continuity

    Service Continuity

    Preventive maintenance to minimize the risk of breakdowns. In the event of a failure, service will be provided within 24–48 business hours.

Your Questions About Filtration

Frequently Asked Questions

  • Is filtered water really better than tap water?

    “Better” is subjective. From a bacteriological standpoint, Luxembourg’s tap water already meets standards. Filtration removes substances that impair the taste (chlorine, particles, VOCs) and results in water that is more pleasant to drink and, therefore, consumed more frequently. That is the main argument.

  • Do the filters remove all minerals?

    No, unless you enable reverse osmosis (optional). The standard filtration system (activated carbon + microfiltration) preserves essential minerals. Completely demineralized water is neither pleasant to drink nor recommended as your primary source of drinking water.

  • What happens if you don't change the filters?

    Filters gradually become clogged, and their effectiveness declines. Our scheduled maintenance prevents this deterioration, so you don't have to worry about it.

  • Are your water fountains NSF-certified?

    Yes, for models designed for demanding environments (healthcare, education, food processing). NSF certification ensures that the filtration system and materials that come into contact with water comply with standards.

  • Can you provide a water quality analysis report?

    Yes, upon request, particularly for healthcare, educational, or quality audit settings. The report includes bacteriological, chemical, and organoleptic parameters.
