With the recent move of foggers into the limelight, one of the most frequent questions we get asked is "are they worth it?". One of our experts here are to share their thoughts and insights on what it is exactly foggers do, how they do it and their efficacy.
Are Fogging Machines Worth It?

Until recently when foggers have moved into a commercial market, there’s a good chance you hadn’t heard of fogging machines before.

These machines have been used for a long time to provide a safe, pathogen free environment in industries such as leisure and care to protect vulnerable people, or in environments where there is a high risk of contamination.

And due to global events being what they are, ultimately every environment is high risk, particularly so with new variants and strains of COVID being discovered almost daily.

But do you know what the difference between a standard spray sanitiser, and an electric or electrostatic fogging machine is? Are you interested in how they work, or thinking about investing in one and want to know if they do work?

This article will cover all you need to know before making that purchase.

What’s Different About A Fogging Machine?

With a standard spray bottle costing £1, and an electrostatic fogging machine costing anywhere upwards of £100, you may be asking yourself what it is that makes one of these machines worth the large upfront investment, especially when at face value these two seem pretty similar.

The reality of it is, these two aren’t all that similar at all.

A fogger doesn’t just spray. It discharges a fine electronically charged mist, the particles being much smaller than that of a standard spray bottle.

This allows them to stay suspended in the air for longer, which in turn allows it to fill an entire room without said particles dropping immediately to the floor and leaving you with a sanitiser puddle.

With the mist consisting of small particles, it can enter porous surfaces such as gym equipment, sofas and bedding which are well known breeding grounds for viruses and bacteria.

And with the mist being positively charged by the fogger, once it comes into contact with a surface it sticks to it.

This is why many disinfecting solutions, such as our BioBarrier, create a literal barrier from bacteria using nano shards that kill pathogens on contact and can last upwards of 28 days without reapplication.

These are also designed to work with concentrated disinfectants and sanitisers due to the ultra-low volume model they utilise, stretching the amount of disinfectant required to carry out a project and delivering exception results on a small budget.

Where Can You Use a Fogging Machine?

Originally designed for high risk areas such as hospitality or care facilities to ensure a safe and pathogen free environment, more recently foggers have begun to shift into a more commercial market.

They excel at quickly and easily sanitising large open areas including offices and hotels, without the need for the man power to do it manually.

The only restriction is that there must be know exterior airflow to the area you’re fogging, as it will interfere with how the fog disperses and create uneven results.

What Do You Use With a Fogger?

For best results, use a concentrated antiviral or antibacterial disinfectant, diluted to the manufacturers recommendations.

Many foggers (such as our 1L fogger and 5L fogger models) have an ultra-low volume design which will maximise the amount of fog produced per bottle from concentrated disinfectants.

We wouldn’t recommend putting any off the shelf, ready mixed disinfectants in.

Once a room is filled with fog, there is no need to wipe it off or interfere with it in any way. Allow it up to 30 minutes to dry, and that’s the process completed.

There’s also the matter of depending on which disinfectant you use, you may or may not need to use PPE (though always advised), is it safe for food preparation areas, how soon can you re-enter the area, etc.

Our BioBarrier is water-based and fully suitable for use in food preparation areas, as well as irritant free and lasts for upwards of 28 days for increased protection.

Do Fogging Machines Work?

So while it may seem like an investment at first glance, hopefully you’re starting to see just how well fogging machines can be utilised.

Fogging machines can cut down on time spent disinfecting an area by up to 4x, with is taking 30 minutes to sanitise an average sized office and 90 to fog a gym hall.

And you can save up to 30% through using concentrated cleaners due to the ultra low dispersion tech, and that’s not including time saved due to the 28 day barrier it leaves on surfaces.

The mist foggers discharge has an average particle size of under 20 microns (if it’s a dry fog) or just over 20 microns (if it’s a wet fog), dry fog is generally preferred for smaller areas, whereas wet fog is preferred for larger coverage, and will come with an adjustable nozzle attached that lets you switch between the two.

The downsides of fogging aren’t non-existent though, depending on which cleaning solution you use, you may not be able to use the fogged area for a small amount of time. Always refer to the manufacturers instructions.

The fog can sometimes find it difficult to reach into the upper corners of room due to gravity, so can sometimes be less effective in these areas.

It won’t get inside closed off areas such as filing cabinets, fuse boxes etc.

Electronics can get damaged if not removed from the area, this can be anything from phones to keyboards or mice. It’s always best to remove anything electric you don’t want to break from the area prior to fogging.
