Nemesis eH2O

Nemesis eH2O Products

Nemesis eH2O is a powerful broad-spectrum disinfectant; used as a spray or fog, killing 99.9999% of harmful germs (highly effective against viruses, bacteria and fungi).

Even though Nemesis eH2O is one of the most effective disinfectants available, it does not contain any hazardous chemicals, so no PPE is necessary and it can be used on almost any surface – even on sensitive skin and on food and in food production areas.

Nemesis eH2O Key Features

  • Broad-spectrum anti-viral and antimicrobial spray
  • Kills germs on contact (within seconds)
  • Ideal for spraying or fogging
  • Employs unique hypochlorous disinfectant
  • Easy to apply spray sanitiser
  • Use as a biocide on any surface – even sensitive skin
  • No messy creams that can act as hosts for germs
  • Non-sting
  • Alcohol-free, so doesn’t dry or irritate the skin
  • 100% Natural antiseptic
  • Eco-friendly – no waste product or harmful chemicals, and bottles are refillable and recyclable

How to use Nemesis eH2O
Ideally, surfaces should be cleaned before disinfection. The frequency of application will depend on the ongoing levels of contamination and the risk levels of those (vulnerable individuals) that are likely to touch the surfaces. (See Coronavirus survival times opposite).

All of the pack sizes shown above provide Nemesis eH2O in a ready-to-use pH neutral solution of stabilised hypochlorous acid.

Spraying: The 65ml pack size is designed to be carried in a pocket or handbag to facilitate the simple disinfection of commonly touched surfaces such as hands, mobile phones, keyboards, light switches, steering wheel, child buggies, toys etc.

The 500ml and 750ml bottles fulfil the same purpose, but are more cost-effective, and possibly slightly less easy to carry. Useful for hospitals, care homes, treatment rooms, offices etc.

The 1 litre, 5 litre and 20 litre containers also reduce the cost of disinfectant and can be used as refills for the hand spray bottles.

Fogging: Nemesis eH2O can also be used with a fogger to decontaminate rooms, vehicles, studios, offices, shops and larger spaces. However, it is good practice to supplement fogging with more frequent spray disinfection of ‘high traffic’ surfaces.

Human Coronavirus Survival Times on Surfaces:


If you pass an electric current through salt water, it produces an anolyte solution made up of >99.3% water, chloride salt and also Hypochlorous Acid (HOCl). We use this process to replicate the production of HOCl which is a naturally occurring chemical in all mammals/. HOCl is produced by the immune system in white blood cells to fight bacteria and inflammation after an infection or trauma. HOCl rapidly eliminates dangerous organisms without harming the body’s cells. It is one of the few agents that is non-toxic to the delicate cells that promote healing of our wounds, whilst simultaneously being lethal to almost all known dangerous bacteria and viruses.


Dangerous organisms cannot develop resistance to Hypochlorous Acid


  • Nemesis eH2O is 100% natural antiseptic
  • No harmful chemicals, no waste product, no preservatives, no colour, no alcohol

Why is Nemesis eH2O so special?

Nemesis eH2O technology mimics the human immune system; utilising hypochlorous acid (HOCl) to combat viruses, bacteria and other pathogenic microorganisms.

The unique process by which Nemesis eH2O is manufactured requires just salt, water and electrolysis. Developed over 12 years, the Nemesis scientists have established a process that delivers a stable form of hypochlorous acid (pH neutral) with a 12 month shelf-life.

Nemesis eH2O is certified as one of the most powerful disinfectants on the market, but remarkably it is environmentally benign; it has no harmful chemicals, no waste product, no preservatives, no colour, no alcohol and no allergic reaction. As a result, Nemesis eH2O can be used as a sanitiser on any surface including sensitive human skin.

Tested and certified as a highly effective biocide, Nemesis eH2O Kills 99.9999% of harmful germs on contact < 1 minute. Fully Compliant with the European Biocidal Products Regulations (BPR product Types 1, 2, 3, 4 & 5), Nemesis eH2O has proven effectivity against Coronavirus, Influenza, E. coli, S. aureus, Norovirus, MRSA and C. difficile. (please see below for a more comprehensive list).


Nemesis eH2O is effective on:

Please note: This is not an exhaustive list. Contact us for advice on any other pathogens.

Nemesis eH2O is supplied as a ready-to-use solution of 150 ppm stabilised hypochlorous acid. This was the concentration employed in all of the Nemesis eH2O certification tests and in the efficacy evidence provided to the European Chemicals Agency (ECHA) to achieve active substance approval under the Biocidal Products Regulation (528/2012) Parts 1, 2, 3, 4 & 5.

Hierarchy of Microbial Resistance to Disinfectants

The table above shows that enveloped viruses (such as that which causes COVID-19) are particularly susceptible to antiviral disinfectants.

All Nemesis eH2O products are tested to rigorous international standards and Nemesis eH2O is fully authorised under the Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) for Parts 1 to 5 (Part 1: Human hygiene, Part 2: Disinfectants and algaecides, Part 3: Veterinary hygiene, Part 4: Food and feed area, Part 5: Drinking water).
Nb. Following Brexit, access to lists of approved disinfectants is available via the Health & Safety Executive website.
