Read frequently asked questions about PuriFog

What is PuriFog?

PuriFog HYPO is a specially treated dry fog that quickly disinfects surfaces, cleans the air and kills COVID-19 to World Health Organization guidelines in indoor spaces of any size and shape.

The fog contains 0.1% sodium hypochlorite in micron-sized droplets, reaching every conceivable surface, unlike other sprays and cleaning systems.

From light switches and keyboard keys to worktops and furniture, nothing is missed by PuriFog.

How does PuriFog work?

At the touch of a button, a cloud of PuriFog fills any contained space within seconds. The specially formulated fog disinfects every surface, whether horizontal or vertical, to protect staff and the public against COVID-19, plus 99.9% of bacteria and other viruses.

Safe on electronics, furniture and paper, PuriFog is ideal for sanitising any professional or domestic environment, including offices, transport vehicles, schools, care homes, retail outlets, and more. It rapidly disinfects spaces of any shape or size, from high ceilings to corridors and everything in-between. PuriFog is even trusted by the NHS to sanitise the inside of ambulances.

The only remnant is a micro-thin disinfectant layer with no visible residue, which is effective for 4-10 days, making PuriFog safe for electronics, furniture and paperwork.

PuriFog COVID protection

Because it disinfects everything it touches and requires minimal preparation and personnel to operate, PuriFog is quicker, more convenient and more effective than a manual deep clean at protecting against viruses (including Coronavirus) and harmful bacteria.

Premises must be clear of all personnel for two hours after PuriFog is administered, and our staff use PPE throughout the process.

PuriFog HYPO has been specifically developed using all the latest guidelines issued by the World Health Organisation to combat the present pandemic of COVID-19.

When can PuriFog be used?

Our technicians are fully trained, DBS checked and can administer PuriFog as part of our regular out-of-hours patrols, which takes advantage of the requirement for the area to be clear of people whilst administering PuriFog.

Have you had a confirmed case of COVID-19 in your workforce? PuriFog can be called upon at short notice to rapidly remove all trace of the virus from any indoor space with no preparation and no need to move furniture around, giving peace of mind to all staff.

How much does PuriFog cost?

Direct Security Solutions offer PuriFog at a very competitive price compared to other solutions, especially considering the speed at which it can be administered and its effectiveness.

Pricing is based on the size of the area that requires treatment, so please contact us for a tailored quote.

Does PuriFog really kill COVID-19?

PuriFog HYPO contains 0.1% sodium hypochlorite, which is prescribed by World Health Organization (WHO) guidelines as suitable for sanitising areas against COVID-19 specifically. PuriFog also kills 99.9% of bacteria and viruses.

Does PuriFog leave a smell or visible residue?

While the fog is present there is a slight citrus scent, however, this will be gone once the fog disperses (2-3 hours from deployment). The disinfectant residue it leaves behind is micro-thin and invisible to the naked eye.

Is the fog safe for electronic devices, furniture, and paperwork? Do we need to put anything away or switch anything off?

PuriFog emits a dry fog that is totally safe on electronics and leaves no marks or stains on furniture or paper. There is no need to prepare the space apart from removing any open food items that may be present.

Will the micro-layer leave a mess or discolour any surfaces?

No, PuriFog will not discolour surfaces or materials and leaves no visible residue.

Why is PuriFog more effective than sprays?

PuriFog is 1,700 times more effective than standard disinfectant sprays. PuriFog particles measure 0.001mm, as opposed to the 1mm of a standard disinfectant spray. This means the fog rises to fill the air and attaches to air particles, viruses, and bacteria. It finds its way into every crack and crevice, including computer keyboard keys, walls, light switches, and everything else you might not even think about in a room. PuriFog gives complete coverage every time.

When can you deploy PuriFog?

Because of the requirement for the area to be clear of people and animals, we typically deploy PuriFog in the evening outside of office hours. We can also deploy during office hours if the building is clear. This often coincidences with the mobile patrols and keyholding services Direct Security Solutions provides to our clients already.

How long does the effect last?

PuriFog leaves a micro-thin disinfectant residue, which you can’t see or feel, that kills COVID-19 plus 99.9% of bacteria on contact. Depending on how much use each surface gets day to day, this lasts between 4 days and two weeks.

How long does it take for the PuriFog machine to distribute fog around a room?

Each blast of fog takes 25 seconds to deploy however, we can move the machine while it is actively distributing fog to cover more areas and can apply subsequent blasts if needed. The fog will take between 2-3 hours to fully disperse, after which we will ensure the area is safe to re-enter.

Can PuriFog be used across the whole building, on multiple floors?

Yes, we may need to do several blasts of fog depending on the size of the premises that require treatment, but this can be facilitated.

Will PuriFog set off our fire alarm?

The fire alarm (if monitored) will need to be taken off watch before we deploy PuriFog – as a Facilities Management and Security business we will liaise with your building management and are able to facilitate this process with you as part of the service. The fire system will be reset and restored before we leave site.

Can anyone be in the room whilst PuriFog is being deployed?

During treatment, no people or animals can be present, as the cleaning chemicals used can be harmful whilst in the air. Our operative wear full PPE to protect themselves. After the fog has been deployed, it will take around 2-3 hours to disperse, after which it is safe to re-enter, when advised by our trained staff.

How is PuriFog priced?

PuriFog is priced based on the size of the premises it is to be deployed in. This is because depending on the total area, we may need to distribute more fog to adequately cover all areas. Please get in touch for a quote based on your specific requirements.

Is PuriFog safe for hospitals and healthcare environments?

Yes, it is totally safe in any environment if the area is clear of people and animals whilst it is deployed. Once the fog has dispersed after 2-3 hours.

We have had a positive case of COVID-19 on our premises, how quickly can PuriFog sanitise the area?

We offer a rapid response service that can be quickly deployed to disinfect the area and kill and trace of Coronavirus in the air and on all surfaces. You don’t need to prepare the premises aside from clearing the area of people and animals and allowing us to de-activate and then reset your fire alarm once treatment has been completed. If you have had a positive case of COVID-19, please contact us or call 0870 027 4589 as soon as possible so we can secure your booking.
