How does HYDRUS disinfect?

HYDRUS Disinfectants are 99.9999% effective at killing bacteria, viruses, fungi and spores. When these products come into contact with bacteria, they cause an imbalance on the cell surface, breaking down the bacteria’s defences, allowing the active ingredient – Hypochlorous Acid- to render it harmless. HYDRUS performs at least 30 times faster than the best household bleach, plus it is also very effective at killing viruses, all without the use of harsh chemicals.

How does HYDRUS work?

HYDRUS products are powered by electrolysed water; safer to use, kinder to your skin and kinder to the environment, free from harsh chemicals, hypoallergenic, non-irritant, non- corrosive and non-staining. During electrolysis the liquid produces Sodium Hydroxide. A little Sodium Hydroxide creates an effective and gentle, cleaning ingredient.

Are there any toxic chemicals in HYDRUS products?

No. HYDRUS complies with the requirements of the European Biocide Regulation EU528/2012 Product Types 1-5, which means it is deemed approved for use with Humans and Animals and it has been tested to BS EN 901 as a disinfectant for drinking water, fit for human consumption.

How effective are HYDRUS products?

EU Regulation Tests show that HYDRUS products are 99.9999% effective at killing bacteria, viruses and fungi.

Where can HYDRUS products be used?

Since it is highly effective at killing bacteria, viruses and fungi, without damaging environment and it is entirely human compatible HYDRUS Disinfectants can be used almost everywhere where disinfection or sanitisation is required. HYDRUS is really effective in kitchen and bathroom areas, as well as walls, floors, food preparation areas, schools, nurseries… the list is endless. 

Do HYDRUS products leave behind any film or residue?

HYDRUS leaves no residue, in fact it destroys biofilm and hormonal residues, then simply evaporates. We only advise that HYDRUS is not applied directly to electronic screens due to the nature of the screen surface. It will cause no harm to electronic screens, but may leave a slight residue which would simply need buffing off with a dry cloth. 


Product Ingredient Questions
Why does HYDRUS have a slight smell of bleach?

One of the constituents of HYDRUS is Hypochlorous acid, which, when it reacts with oxygen in the air gives off a tiny amount of gas, which is what you can smell. 

Here’s a little bit of information on the “bleach smell” and what it actually means…

With the stronger smell of combined chlorine, this means that more bacteria have reacted and been killed. The stronger the smell, the dirtier a surface would have been in the first place. 

For example, a healthy chlorinated pool can emit a light chemical odour, especially if it is an indoor pool and one with less-than-ideal ventilation. The stronger the smell of chlorine, the more bacteria the chemical has eliminated, thus being dirtier before treatment took place.

Hydrus in its purest form is odourless, the odour/bleach smell only generates when the liquid comes into contact with germs/bacteria/proteins, generally any filth. 

This causes the reaction and creates combined chlorine. The liquid reacts with proteins and organic matter. Once you smell the “bleach” smell, you know the reaction has been made and the surface/area is clean.

What is FAC?

FAC stands for ‘Free Available Chlorine’ and in the case of  HYDRUS, FAC comprises two components, Hypochlorous Acid (about 245ppm) and Sodium Hypochlorite (about 15ppm)

What is hypochlorous acid?

Hypochlorous Acid is the substance our bodies produce to fight infection, so its germ killing properties are well known and understood and since our own bodies produce it naturally. It’s the active ingredient in HYDRUS and it has been proven to help kill 99.9999% effective at killing bacteria, viruses, fungi and spores

How is HYDRUS made?

HDYRUS products are made by passing an electric current through a solution of de-ionised water and high purity salt (Sodium Chloride) contained in a chamber fitted with a specially designed membrane. No chemicals are added in the process. All products are natural and 100% biodegradable.


Usage & Storage
What is the best place to store HDYRUS?

HDYRUS is best kept in a cool dark place (i.e. cupboard) and in its original container.

How long can I keep HYDRUS before it stops working?

If kept as recommended, HYDRUS will remain active for at least 6 months after opening, maybe even longer. Storage in a hot or open-to-the-sky place will cause HYDRUS to degrade over a shorter period. Avoid unnecessary opening of the (spray) bottles, open only when empty and refill using our refill Ready to use or concentrate formula.


Health & Safety
Is HYDRUS safe to drink?

The short answer is YES, provided it is being used as directed to disinfect water. In 2015 Electrolysed water was given approved by the Secretary of State under regulation 31 of the Water Supply (Water Quality) Regulations 2000 for use in public water supplies. 

What should I do if I get HYDRUS into my eyes?

HYDRUS is not going to harm you, simply rinse well with tap water.

What happens if I inhale HYDURS?

Nothing; no harm will come to you, your animals or your children. Once HYDRUS is in the air that you breath, it kills the bacteria, viruses spores and pollen. It is known to actually provide relief for those suffering with certain respiratory ailments.

Can I use HYDRUS like Dettol to treat a graze or open wound?

HYDRUS is an Antiseptic and although it has not been registered as a ‘Medicinal Product’, independent tests show that, in addition to killing the bacteria likely to cause an infection, the reactive oxygen in HYDRUS stimulates DNA synthesis and cell division, accelerating the repair of the wound.

Can I use HYDRUS around a baby/child?

HYDRUS is a gentle disinfectant and is highly unlikely to harm your baby’s skin. But as always with baby, try it on a small area first, just in case. Don’t forget, it can be used to disinfect the potty and to rinse baby’s clothes and bedding.

Can I use HYDRUS around my pets?

HYDRUS can be used in a number of ways to help care for your pets. Regular spraying of their bedding, will neutralised pets smells and reduce bacteria. Spray on any wounds to act as an Antiseptic.
