Biolargo Inc

We make life better by delivering simple and sustainable solutions to big problems. We create and refine intellectual property that forms a foundation from which to build and create break-through products and technology for licensure to commercial partners. Our products harness the power of iodine – “Natures Best Solution” – to eliminate contaminants that threaten our water, our health and our quality of life.

We invent, patent, prove and partner – to create best-of-class products and technology for commercialization as we build value for our shareholders and deliver benefits to our world.

Invent – Three Platform Technologies

We feature three patent protected platform technologies with diverse product opportunities across multiple industries – the AOS Filter, CupriDyne, and Isan. Each features the use of the all-natural iodine molecule. While they all use iodine, they are quite different in terms of the methods by which they exploit the use of iodine, the form and composition of iodine used, and therefore their function and value proposition can be quite different for each commercial application.

AOS Filter

The AOS Filter is our invention that combines iodine, water filter materials and electrolysis within a water filter device. Our filter generates extremely high oxidation potential in order to oxidize and break-down, or otherwise eliminate, soluble organic contaminants like acids, solvents, sulfurs, oil and gas by-products, and pharmaceutical by-products which are commonly found in all sorts of contaminated water. It also achieves extremely high rates of disinfection to eliminate infectious biological pathogens like salmonella, listeria and ecoli.

Extremely high oxidation potential is the key. The term ‘oxidation potential’ refers to the measure of the performance in which an oxidant is able to ‘break down’ a material through, in simple terms, the addition of oxygen and the transfer of electrons. Two commonly understood examples of oxidation are, as salt air rusts a shipyard anchor, or as fire is able to dismantle wood and turn it into ash. The key to our AOS Filter is its ability to generate extremely high oxidation potential in a continuous flow device that attacks contaminants in water that flow through the AOS Filter. The extremely high oxidation potential enables the AOS Filter to achieve performance results that researchers at the University of Alberta refer to as, ‘unprecendented’. Our AOS Filter embodies a break-through in science which led to BioLargos co-founding of an ongoing research chair to solve the contaminated water issues associated with the Canadian Oil Sands at the University of Alberta Department of Engineering with the top five oil companies in Canada, the regional water district, and various environmental agencies of the Canadian government. Our work is continually expanding into a number of commercial applications with a key focus on food processing, agriculture and oil and gas. We are also evaluating opportunities in the maritime industry, mining, storm drain recapture / recycling, and drinking water. It is an award-winning invention that is supported with science and engineering financial support and grants from various federal and provincial agencies in Canada. The financial support is expanding along with the work to develop commercially available designs. We believe the AOS Filter has an important and substantial commercial opportunity in every segment of the water treatment industry.


Our CupriDyne formula is used to deliver iodine within products. It can be delivered in any physical form, and can be combined with other ingredients, like fragrances in our odor control products, and primitive surfactants in our stain and odor products. Additional ingredients can often be added without sacrificing its practical and safe antimicrobial functions as well its oxidation potential. Our product designs include liquids, sprays, gels, powders, coatings and absorbents.

Safe and effective is the key. Each of our product designs delivers nature’s broadest spectrum and most potent disinfectant – iodine – safely and precisely to achieve effective broad-spectrum disinfection, unsurpassed odor and moisture control, and effective and gentle wound healing. Our primary ingredients, as well as reaction by-products, are “generally recognized as safe” (G.R.A.S) by the U.S. Food and Drug Administration as food additives in their basic forms. Its commercial product opportunities are diverse and we have an extensive menu of product designs in various stages of commercialization and licensure development, discussed in detail below in the “Commercial, Household and Personal Care Products” section. We specialize in delivering iodine, nature’s broadest spectrum and most potent disinfectant and essential nutrient, in safe, environmentally friendly, non-staining, non-toxic and effective product designs.

CupriDyne is unique. The iodine most of us are familiar with, sold in pharmacies and used by hospitals, has severe limitations – it is considered toxic, causes staining, and contains a limited dose of the active oxidizing ingredient. Our CupriDyne technology, on the other hand, directly addresses many of these shortcomings – it delivers iodine’s oxidizing ingredient (“free iodine”) with precision, ranging from very small doses up to very large doses with more than 20 times the power of traditional iodine. We can deliver iodine so that it is both non-toxic and non-staining, thus extending its usefulness well beyond historical product applications. Our formulations expand the functionality of our products well beyond simple disinfection.

Isan System

The Isan System is an automated iodine dosing system. It is the winner of a Top 50 Water Technology Award by the Artemis Project and a Dupont Innovation Award. Precise dosing combined with a straight-forward ‘set-it-and-forget-it’ automated computer controlled system is the key. The system features controlled measuring, flow control, dosing and iodine extraction/removal technology as well as an automatic tracking system that precisely delivers iodine in calibrated doses into a water steam or container of water. The Isan system has been proven to substantially reduce the incidence of fungal growth, spoilage, organisms and pathogens in water and on food. The system is able to operate at high flow rates.

First developed in Australia, the Isan system was initially registered with the APVMA (Australian Pesticides and Veterinary Medicines Authority) and FSANZ (Food Standards Australia and New Zealand) in Australia and New Zealand. The system has meaningful use and commercial value in any industry that can benefit from a precise use of iodine in water, like; agriculture, food production and processing, manufacturing, industrial water processes, irrigation supply.

Patent - an Expanding Intellectual Property Estate

We have 16 patents issued and multiple pending. We believe these patents provide a foundation from which to continue building our patent portfolio and we have reasonable basis upon which to rely on our patent protections in the field of art in which we practice. We also rely on trade secrets and technical know-how to establish and maintain additional protection of our intellectual property. As our capital resources permit, we expect to expand our patent protection as we continue to refine our inventions as well as make new discoveries. See the detailed discussion below of our patent portfolio.

Prove - a Continual Process

We have invested time and money in a wide array of third party testing, side-by-side comparisons and third party verifications to support our most important technical claims. The basic attributes of iodine are well understood by science and industry. We have evidence and experience to substantiate the following bold claims:

AOS Filter- when compared to the best of class competition we are
