EcoPro uses an ultra-advanced 5-stage Microfiltration technology with activated carbon in their replacement filters. The activated carbon block, made from coconut shell, is capable of absorbing chemical, gas, metal, and organic elements thanks to its microscopic structure and highly porous surface. When tap water passes through the filter, contaminants are trapped in the spherical particles of activated carbon, such as lime, chlorine (responsible for bad taste), microplastics, sand, rust and sediments, lead, mercury, salmonella, legionella, pesticides, herbicides, drug residues, nitrates and over 100 substances. The result is clean and filtered water, ready for consumption.
