Since March 2020, the world has been at a standstill; businesses and organisations have been in limbo and there are countless questions surrounding the relaxation of rules and the return of shops, gyms, restaurants and other businesses, and organisations.

Regulations, and restrictions are everywhere to minimise the spread of COVID-19.

The demands being asked of business owners are having a huge impact; less income, more spend, not to mention mass confusion and in some cases, worry and fear.

Arrgghhh, it is enough to make your head implode!

We are not here to add to the confusion.

The stipulations vary for each business and sector, but one overriding rule is hygiene; hygiene to decontaminate and ensure human safety.

This is where we can help.

The purpose of this article is to arm you with more information and answer any questions you might have on fogging. That ways it allows you to make an informed decision on how to decontaminate your premises quickly, effectively, and safely and to decide whether fogging is the right fit for you.

What is fogging?

Fogging is a method of spraying or misting liquid (cleaning fluids, insecticides, disinfectants etc) using a fogging machine, also known as a fogger or electrostatic sprayer. Depending on the specifications of the fogger used, the droplets that are sprayed can be so small that, when dispensed, they are dry.

To allow you to determine how ‘dry’ the mist or fog is, you need to know the micron size of the particles (μm). All good fogging machines should have the particle size stated within the technical specifications at the very least. For a fogger to produce a dry fog the micron size produced need to be less than 10(μm).

What is a micron?

A micron is a unit of length equal to one millionth of a metre, used in many technological and scientific fields

To put this into perspective, the cross section of a human hair is 50 microns (μm) and even with 20/20 vision, a human cannot see anything smaller than 40 microns.

To achieve a dry fog the micron size needs to be less than 10(μm) – preferably 5(μm)

Tiny eh!

What is Hypochlorous acid?

Hypochlorous acid (HOCL) is becoming increasingly well known for it safe and effective anti-microbial properties.

HOCL is present in all humans. If you were to become sick or cut yourself, your body produces Hypochlorous acid and teams up with your white blood cells to combat any infection.

ESOL™ is the brand name for the HOCL products we make on site here in Scotland.

The HOCL we produce is done by the electrolysis of ordinary tap water containing saline (salt). The electrolysis process produces two separate solutions from a double chambered cell; the positive chamber produces a solution containing a range of oxidisers and a small amount of hypochlorous acid. The negative chamber produces sodium hydroxide.

The resulting ‘water’ from the positive chamber is ESOL™ (HOCL) – an effective anti-viral liquid that is safe to humans, animals, and the environment.
HOCL is known by several different names:

• Electrolyzed oxidizing water
• Electro-activated water
• Electro-chemically activated water solution
• Electrolysed water (UK spelling)

ESOL™ looks and feels just like ordinary water, it is non-toxic and turns back to ordinary water. 

Despite this, ESOL™ is capable of extraordinary disinfection.

ESOL™ is BSEN14476 and BSEN1276 approved and is has proven to effectively destroy pathogens and enveloped viruses including:

• Coronavirus
• E-coli
• Salmonella
• Norovirus
• Legionella
• Listeria
• Clostridium difficile

Where can I buy a fogger?

There are many fogging/misting machines on the market today, all of which will spray a fine mist of your chosen liquid.

Bridge Biotechnology have developed an ESOL™ fogger that produces a dry fog and when used with ESOL™ it helps kill airborne bacteria and adds another layer of protection to any cleaning regime.

Before buying a fogger, what features should I check?

Price – Foggers can vary largely in price from £100 – £1,000’s!

Micron size – The ‘wetness’ of the fog depends on the micron size expelled from the fogger. If you are looking for a dry fog, make sure your fogger can produce fog at a micron size of 5-10 (μm).

Delivery time – Many of the fogging machines on the market are not manufactured in the UK.

Check the origin of your fogger to ensure you will not be waiting weeks on the delivery.


Businesses and organisations want to implement every hygiene measure they can, into their daily routines, to ensure that their staff and customers are protected.

Fogging ESOL™ allows you to, safely, kill any bacteria and viruses that may be in the air. At the same time, the ESOL™ fog that settles on surfaces (and people) will also kill any bacteria missed by routine surface disinfection.

Once switched on, ESOL™ foggers do not need any manual intervention for them to fog a whole room.

HOCL (hypochlorous acid) is an entirely safe and environmentally friendly alternative to harmful chemicals.

ESOL™ is BSEN14476 and BSEN1276 approved.
