No. They only need:- A power source (grid, solar, or battery)- Access to ambient air

Yes, the taste of Kumulus water is consistent wherever you are. Our multi-stage filtration and controlled mineralization process ensure the same fresh, clean, and balanced flavor, regardless of the local air quality or climate.

Our water meets and exceeds World Health Organisations and EU drinking water standards. It is filtered, UV-purified, and enriched with essential minerals for taste and health.

Yes. The mineralization process ensures a fresh, neutral, and pleasant taste, similar to high-quality bottled water.

One solution produces 20 to 30L per day. However, this will depend on the environmental conditions: usually decreasing slightly in the winter, and increases in the summer. This is great, because humans consume more water in the summer relative to winter.

Kumulus solutions can be powered by all types of sources: solar panels, electricity grid, or battery. The Amphore and Boks use 0.4 to 0.8 kWh / litre, depending on climate conditions. The Kumulus water coolers use 0.5 kW per day.

Each filter has its own replacement cycle, which also varies depending on the environment in which the machine operates. For instance, in desert conditions, the particle filter needs to be changed more frequently than in rural areas. Our maintenance team manages this process end-to-end, remotely monitoring filter status and performing scheduled technical visits to ensure timely replacements.

No. The volume of air processed by Kumulus solutions is minimal compared to the natural airflow in the environment, and it does not alter local humidity levels. For now, our technology has no measurable impact on ecosystems or air quality.

No, Kumulus' solutions are designed so that air quality does not affect the safety or purity of the water produced. Incoming air passes through multiple filtration stages to remove dust, sand, and airborne pollutants before condensation. The resulting water is then UV-sterilized and mineralized, ensuring it meets WHO and EU drinking water standards. We have verified this through over 6,000 water quality tests conducted in environments ranging from clean coastal areas to heavily polluted industrial zones.

Yes. The air intake passes through specialized filters that remove dust, sand, and airborne pollutants before water production begins. We have conducted over 6,000 water quality tests in all types of environments, from industrial zones to construction sites and desert regions, consistently meeting international drinking water standards.

Yes. Our water is free from contaminants and enriched with essential minerals, making it safe for all ages. Kumulus machines are already in daily use in many schools, ensuring students have reliable access to fresh, healthy drinking water.

Anywhere with: Aadequate airflow (installation outside recommended), sufficient humidity and temperature, a stable surface (level ground or mounting frame). We serve offices, schools, construction sites, ports, industrial facilities, resorts, and rural communities.

Absolutely. Our systems are designed to integrate with solar panels and battery storage, making them ideal for off-grid locations.

Kumulus machines can operate in a wide range of environments — we’ve even tested them successfully in desert conditions. They work anywhere with temperatures above 5°C, though water production will vary depending on humidity and temperature. In optimal conditions, they can produce up to 45 liters per day. For best performance, we recommend areas with relative humidity above 30% and warm temperatures, such as Mediterranean, tropical, and coastal regions, as well as arid zones with higher night humidity.

The Kumulus machines capture the air, condense the air into water, filter it through 4 different filters, and then mineralizes it before coming out of the tap for the user to drink. Check out our Instagram explainer videos here!
