Here are some common questions about the EVO Home.

Getting Started

How is it made?
Electrolysed water is made by passing electricity through a solution of water and salt. The electrolysis process causes the water (H20) and the salt (NaCl) to split and re-arrange into two new compounds. These are hypochlorous acid (HOCl) and sodium hydroxide.

Hypochlorous Acid (HOCl) which is a super effective disinfectant that kills germs and bacteria, and is also what the human body produces to naturally protect and heal. Plus, a small amount of Sodium Hydroxide – which is a super effective cleaning agent commonly found in everything from toothpaste and skincare products to household cleaners.

A small amount of vinegar is also added to the salt and water solution before electrolysis. This is done to achieve an optimal pH of the solution to allow for optimum amounts of HOCl to form.

Does it have a scent?
Electrolysed water has a very mild ‘swimming pool’ scent. This mild chlorine smell occurs during the electrolysis process and is from the active ingredient – hypochlorous acid. There are no additional fragrances or additives in the solution.
Is it safe?
Yes, electrolysed water is completely safe. The main active ingredient of electrolysed water is hypochlorous acid (HOCl) which is a powerful oxidant that is also completely safe and natural. It is found in our blood as a biological oxidant that is generated by our white blood cells. There are no additives, fragrances or preservatives in the solution.
Is it safe for babies and pets?
Yes, electrolysed water is completely safe as it is non-toxic and does not contain any additives, fragrances, dyes or preservatives. This makes it ideal for anyone struggling with asthma, allergies and skin irritations that are agitated by strong chemicals and fragrances etc.
Is it easy to make?
Yes, it is very easy to make. You simply fill the EVO Home pitcher with tap water, add salt and vinegar and stir. You then press the activation button on the EVO Home to start the electrolysis process. After 5-minutes the activation is complete and the electrolysed water is ready to use. You can then fill up your EVO Mist spray bottle to use as needed.
Why does PH matter?
At pH 5, over 99% of the free chlorine molecules created during the electrolysis process will be HOCl. At pH 6, over 90% of the free chlorine molecules will be HOCl. At pH 7, over 80% of the free chlorine molecules will be HOCl. At pH 8, only 20% of the free chlorine molecules will be HOCl.
Does it need vinegar?
The ideal pH range for the solution before electrolysis is in the 4-5.5pH range. This will result in a 5-6pH range after electrolysis. We recommend adding 5ml’s of vinegar per 1 litre of water to reach this optimum pH level.
Can I use any water?
Tap water at room temperature is best to use. If you have very hard water, filtered water is advisable to prevent any build up on the electrodes over time.
How much salt do I use?
You should add 2g of fine non-iodated salt per 1 litre of water. Stir the solution well to make sure that the salt is dissolved. It is the salt (NaCl) that will be ionized into the active ingredient of HOCl.
Does it matter if I add vinegar or salt first?
No. You can add either first. You can also choose to purchase a bottle of EVO Activation Solution which is a premixed solution of salt and vinegar for convenience and ease of use. You can simply add 10ml of Activation Solution to 1 litre of water.
Why not sea salt?
Sea salt and iodated salt both have added minerals. This causes build up on the electrodes of the device over time which is why refined, non-iodated salt is recommended. In addition the strength of the HOCl solution will be affected as the HOCl will attempt to eliminate the additional minerals from the salt.
Will the salt effect the pH of the water?
No. Adding salt to water does not result in any chemical reaction and will therefore not affect the pH.
How long does electrolysed water last for?
The shelf life of electrolysed water once it has been created and bottled is 7-14 days. After that it will return to salt water. In a closed container, such as the EVO Mist spray bottle, the concentration of hypochlorous acid decreases at about 1% per day if stored at room temperature and protected from UV light.
What is PPM?
PPM stands for ‘parts per million’ and it’s a term used to explain the concentration of various solutions such as disinfectants. With 1 x activation and 2g of salt, EVO Home will create HOCl at 100ppm. If you’d like to make a stronger disinfectant you can activate the solution a second time to create a HOCl solution of 200ppm (without adding more salt). HOCl solutions of 200ppm are approved by the EPA for use in kitchens and on food preparation surfaces without the need to wipe away or rinse after use.
Must I rinse off after using?
In most instances no. Hypochlorous acid can be used at 60ppm for food sanitation (such as removing pesticides and bacteria from fruit and vegetables) without requiring a post-rinse. Food preparation surfaces only require a rinse afterwards if the solution is more than 200ppm.
Does it kill bacteria and viruses?
Yes. HOCl kills bacteria and viruses. HOCl is EPA approved for use as a disinfectant and sanitiser. HOCl is 99.9% effective and is up to 100 times more efficient at killing bacteria than chlorine bleach or sodium hypochlorite (NaOCl)
Does it kill COVID-19?
Yes. Research has proven that HOCl is effective against SARS-CoV-2 (COVID-19 virus). The American EPA approved HOCl for use as a disinfectant in 2002, and in March 2020 for use against COVID-19.
Is there any 3rd party testing on HOCL and EVO Home?
Yes. EVO Home has been independently tested at a 3rd party laboratory with test results confirming that the HOCl created has a 99.97% virus reduction rate in 30 seconds; 99.98% virus reduction rate after 60 seconds and 99.99% virus reduction rate after 5 minutes.
Does it get rid of smells and odour?
Yes. HOCl neutralizes the bacteria that cause smells. This makes it ideal to deodorise bins, pet bedding, sports gear, smelly bathrooms, nappy bins etc. Just spray liberally and leave to dry. To freshen up and remove smells from clothing, spray items liberally and then hang them in the fresh air to dry naturally.
Does it treat mould and fungus?
Yes, HOCl kills both mould and fungus just as effectively as bleach. However please note that because it does not contain any additional whiteners it won’t remove rust marks and very stubborn stains on porous surfaces like grout.
What surfaces can it be used on?
You can use it to clean virtually any surface and to disinfect virtually any surface.

You can clean your kitchen and bathroom (glass, grout, tile, porcelain), counter tops (stainless steel, sealed stone like granite, marble and quartz) and floors including wood and laminate. You can clean and disinfect plastic and rubber items such as cutting boards, plastic toys, pet toys, high chairs and prams/strollers. You can clean colorfast items such as rugs and car seats after accidents or spills – if you have any concerns, test on a small area first.

Does it leave streaks or residue?
HOCl does not leave behind any harmful residues. Simply use your EVO Mist spray bottle to spray the HOCL solution on to any surface and then wipe dry with a clean cloth or paper towel. On surfaces such as glass and stainless steel, you should wipe the surface until it is completely dry as there are no drying accelerants in the solution such as in ammonia or alcohol based cleaners.
Does it clean well?
Electrolysed water is a very effective cleaner. For very dirty areas that have a build-up of residue or very ingrained stains you may need to use a mild abrasive, such as bicarb, for initial cleaning.
Does it disinfect well?
Yes, HOCl is a highly effective disinfectant and has been an approved EPA disinfectant since 2002. The use of disinfectants is often misunderstood. Disinfectants need to be left on a surface for a certain period of time in order to reach maximum efficacy. To disinfect properly, spray HOCl onto the surface and leave for 10-minutes. Then wipe dry with a clean cloth or paper towel.
Is it the same as diluted bleach?
No, hypochlorous acid is not the same as bleach. The formula for sodium hypochlorite (bleach) is NaOCl and the formula for hypochlorous acid is HOCl.

Bleach is defined as
1) having a pH of 11+
2) being at a concentration high enough to remove the colour from fabric
3) 99%+ NaOCl

None of these apply to hypochlorous acid. In addition, HOCl is a much more efficient antimicrobial than bleach. This means you don’t need to use nearly as much which is why HOCl is so much gentler to use.
