Evodrop is a Swiss water treatment company specializing in drinking water purification, contaminant filtration, and the worldwide first bio-based salt-free limescale solution with Malic Acid. Founded in 2019 and headquartered in Brüttisellen, Zurich, the company develops and manufactures water treatment systems designed for residential, commercial, and industrial use.

The company is known for combining membrane-based filtration technologies with organic descaling methods, with a focus on addressing modern water quality challenges such as PFAS contamination, chlorine, microplastics, heavy metals, pesticides, pharmaceutical residues without having to filter minerals out of the water, without electricity, and without wastewater.

Overview

Evodrop designs water treatment solutions intended to go beyond conventional filtration and salt-based softening systems. Its technologies are marketed for use across entire household plumbing systems as well as for targeted drinking water treatment. According to independent, accredited laboratories, among others SGS, its systems are capable of removing a wide range of contaminants from tap water, including long- and short -chain PFAS, chlorine, pesticides, pharmaceutical residues, microplastics, and heavy metals for every application – whether for the shower only, the kitchen, or the entire house.

Technology

Filtration systems

Evodrop offers different filtration options, ranging from Orbital Osmosis, which filters all contaminants including minerals, to solutions that retain minerals in the water, tailored to individual needs or specific industrial requirements.

Evodrop employs a proprietary membrane-based filtration technology described as an advancement of reverse osmosis. The system is designed to utilize the full membrane surface, achieving a water-to-water ratio of approximately 1:1, compared to higher waste ratios typical of conventional reverse osmosis systems. The membranes are designed for extended service life, with reported capacities of up to 10,000 liters per membrane.

The filtration systems target contaminants down to approximately 0.0005 micrometers, including all known contaminants in water.

Evodrop’s microfiltration reliably removes contaminants down to a proven size of 0.002 micrometres, whereas conventional activated carbon filters typically filter only down to around 0.05 micrometres.

Salt-free descaling with malic acid

A distinguishing feature of Evodrop’s systems is the use of Malic acid for limescale prevention. Malic acid is a naturally occurring organic compound found in fruits and involved in human metabolism. In Evodrop systems, it is used in a complexed form to bind carbonate ions and prevent calcium carbonate deposits in pipes, boilers, and household appliances.

The system is protected by patents and sets new benchmarks in descaling worldwide.

Unlike conventional ion-exchange softeners, which replace calcium and magnesium ions with sodium, Evodrop’s approach does not increase sodium levels in drinking water and does not require salt regeneration or produce saline wastewater. Independent testing by accredited laboratories, including DVGW testing in accordance with standard W512, has demonstrated a remarkable descaling performance, for which the system was awarded the highest possible grade of 1.

Research and development

Evodrop states that its product development is based on hydrological research and interdisciplinary scientific analysis, incorporating physical, chemical, and biological processes involved in water systems. The company’s research approach focuses on understanding natural water cycles and dynamics to design treatment technologies that maintain mineral content while preventing scale formation and eliminating contaminants.

The company collaborates with international and accredited testing laboratories to evaluate system performance under standardized and real-world conditions.

Sustainability

Evodrop promotes on-site water treatment as a means of reducing reliance on bottled water and minimizing transportation-related environmental impacts. Limescale-free systems can improve appliance efficiency, extend equipment lifespan, and reduce energy consumption. Its salt-free descaling systems are designed to operate without producing contaminated regeneration wastewater and require minimal ongoing maintenance.

Independent studies, water utilities, and several U.S. states, such as California, which have banned the installation of salt-based systems, confirm that salt-based systems place a burden on the environment and may also pose health risks due to increased sodium levels.

Awards and recognition

Evodrop reports having received several industry awards for its technologies, including the German Innovation Award, the Aquatech Innovation Award, the Energy Globe Award, and recognition as Water Filter Specialist of the Year. These awards have been cited by the company as acknowledgment of its technical innovation and market readiness.

Applications

Evodrop systems are used in a range of settings, including single-family homes, multi-unit residential buildings, medical practices, hospitality venues, and industrial facilities. The systems are modular and can be configured for specific needs, from kitchen-level drinking water filtration to whole-building water treatment with PFAS filtration and salt-free descaling.
