Boiling tap water is one of the oldest emergency treatment methods for drinking water. It is simple, fast, and effective against many biological risks. But it is often misunderstood. Boiling does not make water “pure.” It mainly addresses microorganisms. It does not remove many chemical contaminants, and in some cases it can increase the concentration of substances that remain in the water after evaporation. That distinction matters. Why Boiling Matters Boiling is useful when drinking water may be contaminated with disease-causing microorganisms. Heat can inactivate bacteria, viruses, and parasites, which is why public health agencies recommend boiling during microbiological contamination events or boil-water advisories. The CDC recommends bringing clear water to

Backflow is one of the most overlooked risks in household drinking-water systems. Even when the public water supply delivers clean and compliant water, contamination can still occur inside the building if water flows in the wrong direction. Drinking-water systems are designed for controlled, one-way flow: from the supply network to the tap. Backflow breaks this principle. It allows used water, non-potable water, or contaminated liquid to move back into drinking-water lines. This can happen through pressure changes, faulty installation, missing protection devices, or incorrect use of hoses and connected appliances. Why Backflow Matters Backflow creates a direct contamination pathway inside the household system. The risk is not always visible, and it

Munich, May 2026 — IFAT Munich once again brought together the global environmental technology industry, with around 3,400 exhibitors from around 60 countries presenting solutions across water, recycling, and circularity. For Klar2O, being part of this environment was more than a trade fair visit. It was a direct opportunity to listen, connect, present our technology, and understand where the water sector is moving next. From the first conversations on-site, one thing became clear: the demand for practical, scalable, and sustainable filtration solutions is growing fast. Companies, engineers, product teams, distributors, and industry professionals were not only interested in cleaner water. They were asking the right questions: How can filtration become more
