How to choose the best water purifier device? FOCUS on countertop water purifiers

With so many water purifiers on the market, how do you make the right choice?

Here are the key factors to help you find a system that fits your daily needs:

💧🔬 Filtration Method: Efficiency Comes First

Good filtration removes chemical residues, chlorine, heavy metals, pesticides, and even microplastics. The technology used makes all the difference.

Main filtration types include:

  • Activated carbon (effective for taste and odor),
  • Ultrafiltration (targets fine particles),
  • UV light (neutralises bacteria and viruses),
  • Reverse osmosis – the most complete, removing up to 99.9% of over 1000 contaminants.
  • Water purifier vs filter jug: which is better?

    Pitchers and tap filters mostly rely on activated carbon. They’re great for chlorine taste or odor but limited against some invisible pollutants. A reverse osmosis (RO) water purifier, however, includes multiple filters (sediment, carbon, RO membrane) and eliminates most harmful substances. Downside? It also removes essential minerals — which brings us to the next point.

    💧⚡️ Remineralisation: For Healthy, Great-Tasting Water

    Over-purified water can taste flat or even slightly acidic — and without minerals, may be less beneficial long-term. That’s why some systems add minerals back into the water for balance and better taste.

    ⚠️ Be careful: Not all remineralisation technologies are equal. A basic passive remineralising filter can give inconsistent results depending on water contact time or filter age. For a real alternative to bottled mineral water, go for active, controlled remineralisation — ensuring consistently mineralised water with great taste.

    💧⭐️ Brand Reliability: Safety and Peace of Mind

    A water purifier is a health device, so your should check which brands of water purifiers are most reliable. It should be rigorously designed, certified (e.g. NSF58), and supported by good customer service. Choose a reliable brand with quality materials and traceable production.

    💧✨ Design & Size: A Matter of Space and Style

    Some purifiers are installed under the sink, others sit on the countertop. A good kitchen water filter with no installation should be compact, quiet, stylish, and convenient for everyday use.

    Under-sink models are discreet but require fixed installation — not ideal if you move house. Countertop “plug & play” systems are far easier to integrate and more flexible.

    A design water filter for the kitchen is also a great way to combine wellness and aesthetics.

    💧💵 Price: How Much Does a Compact Water Purifier Cost?

    For a quality model, prices generally range between €400 and €800 depending on features (filtration power, flow rate, noise, remineralisation, design, filter life, aroma options, etc.).

    What About LANGWATER?

    A true Swiss alternative to bottled water

    We created LANGWATER to offer water as pure and balanced as bottled mineral water — without plastic.

    We chose reverse osmosis, known as the most effective filtration technology. A dual pre-filter (sediment and carbon) protects the RO membrane, and a final UV stage ensures complete purification.

    Our Swiss engineers designed a unique system with no internal tank: water is purified instantly on demand — avoiding stagnation and any risk of bacterial contamination.

    And as no existing remineralisation system met our standards, we spent over 12 years developing a patented liquid-based technology: LANGPAK.

    The result? Premium, constantly mineralised water — customisable, with or without natural flavours — right at home.
