Alkanatur

What Alkanatur does

Alkanatur Drops SLU is a Spanish private limited company headquartered in Spain that designs, manufactures, and sells water filtration products under a direct-to-consumer e-commerce model. Its proprietary Alkamicronized Selective® bioceramic technology combines coconut activated carbon with bioceramic components to purify, alkalize, ionize, and hydrogenate water, producing alkaline water at pH 8.5-9.5 with antioxidant capacity (ORP up to -700mV) and 18mg/L of bioavailable magnesium, while removing up to 99% of chlorine, heavy metals, pesticides, and microplastics. The product line spans entry-level plastic and glass pitchers (€77.77-€119.79), shower filters (€49.77-€99.70), under-counter ultrafiltration systems (€408-€538), and a premium direct-flow reverse osmosis system (€1,777), supplemented by recurring filter replacement revenue.

The company distributes exclusively through its own multilingual e-commerce storefront, shipping to seven European countries (Spain, Portugal, France, Belgium, Luxembourg, Netherlands, Italy) with monthly financing plans starting at €8.22/month. Alkanatur's central differentiator is its evidence base: more than 500 cited scientific studies, UNE 149101 standard compliance, endocrine-disruptor-free certification from IBS Granada, and ongoing clinical research partnerships with CSIC, University of Granada, University of Vigo, University of Almeria, ACCU, and Puigvert Foundation. Customer segments include health-conscious consumers, athletes, beauty/skincare-focused users, residents of hard-water regions, and an emerging medical/clinical vertical via the Alkanatur Medical sub-brand, which offers SEAFORMEC-accredited biomedical consultations.

Core offering

Alkanatur designs and manufactures water filtration products in Spain, including glass and plastic alkaline pitchers, shower filters, under-counter ultrafiltration systems, and direct flow reverse osmosis systems. Its products use patented Alkamicronized Selective bioceramic technology combined with coconut activated carbon to purify, alkalize (pH 8.5-9.5), ionize, and hydrogenate tap water while adding bioavailable magnesium and removing chlorine, heavy metals, pesticides, and microplastics.

Product overview

Alkanatur offers a comprehensive water filtration product line focused on producing alkaline, antioxidant water. The core products include the Alkanatur Drops Jug (plastic pitcher) and Alkanatur ClearDrops Glass Pitcher, both using proprietary Alkamicronized Selective bioceramic technology with coconut activated carbon filters. These pitchers purify water by removing up to 99% of chlorine, heavy metals, pesticides, and other toxins while adding 18mg/L of bioavailable magnesium. For larger-scale filtration, Alkanatur provides the Depure Ultrafiltration System (under-counter or countertop installation) and the Total Depure 800 Reverse Osmosis System with 6-stage filtration. Complementary products include replacement filters (Original Formula, Low Magnesium Emission, and Zeolite Clinoptilolite variants), RainDrops Shower Filters for skin and hair protection, an Alkalinising Ionising Filter cartridge for existing osmosis/ultrafiltration systems, and portable bottles (GO Metal Filter Bottle, Harmony Bottle, Borosilicate Glass Bottle, and BPA-Free Bottle). All products are manufactured in Spain with certifications including UNE 149101 standard compliance and are free of ion exchange resins and endocrine disruptors.
