Improving control of indoor air pollution

Keeping pathogens at bay with effective air purification

With many of us now spending up to 90% of our time indoors, the quality of the indoor air we breathe has become more important than ever. Unless there is proper ventilation, we are at risk of inhaling airborne contaminants that could prove damaging to our health. These include gases, vapors, dusts, fumes and aerosols which are dispersed as solid particles into the air.

As the ultimate air purifying solution, Scarecrow units safely clean and purify the air by inhaling bacteria, viruses and odours, eliminating these harmful pathogens with medical-grade filters and UV-C rays.



What is indoor air pollution?

Indoor air pollution is a combination of the chemical, biological and physical contamination of the air inside, from chemicals, dust, dirt, viruses, bacteria or gases.

Without adequate ventilation, these contaminants can cause both short and long-term health effects, including irritation of the eyes, nose and throat, headaches, as well as dizziness and fatigue. In long-term cases, health problems can arise years after exposure to a pollutant, such as respiratory disease.

The key to reducing indoor air pollution is sufficient ventilation. This could include bringing in outdoor air to dilute pollutants from indoor sources. Although this might be a plausible option during the summer months, winter brings new challenges in the way of freezing temperatures and an increase in viral infections. For many facilities, opening a window to allow outdoor air in is not always a viable solution to ventilate a space.

Instead, a smart solution is to install a ventilation system that cleans and purifies the air without the need to open windows.




Understanding airborne viruses

Airborne viruses can be transmitted by inhalation of microscopic particles generated from breathing, talking and singing – not just via droplets as a result of coughing or sneezing. These airborne, aerosol particles can actually pose a risk of infection beyond the two metre social distancing guidance.

Just like a droplet caused by coughing or sneezing, an airborne, aerosol virus is emitted from the mouth. However, differently to droplets, aerosol particles float, lingering around us until something draws them away. As a result, these stagnant aerosols can be more of a threat to our health, particularly indoors where poor room ventilation enables the virus to linger for much longer, building up in the air.




What indoor areas are at risk of inadequate air quality?

The source of poor indoor air quality is insufficient ventilation, which can exist in various business premises or locations, such as:


Offices & conference venues

Air quality issues in the workplace are often the result of sealed buildings and offices, often filled with large numbers of employees. Without proper ventilation, the inadequate circulation of fresh air becomes a large contributor to absences, poor job performance and other physical symptoms.

Restaurants & cafés

Often those who are visiting a café, bar or restaurant are sitting in the same space for hours at a time, surrounded by people, meaning ventilation of this confined indoor area is key to reducing exposure to contaminants.

Care homes

Indoor air pollution and lack of ventilation within a care home can have harmful effects on the health of its elderly residents. It can also increase the spread of the airborne transmission of pathogens.


Schools are often poorly ventilated spaces, with associations noted between indoor air pollutants and the onset of early health problems and lack of productivity. For children and staff alike, healthy air is crucial in providing pupils and teachers with a safe, healthy, productive, and comfortable environment.


These confined workout chambers, with breathless exercisers, are a breeding ground for polluted indoor air and therefore an increased likelihood of infection transmission.



Improving indoor air quality with Scarecrow UV Air Purification units

Proper ventilation is vital when it comes to clean indoor air. However, opening a window or door is not feasible in many of the aforementioned environments.

Scarecrow UV purification towers clean and purify the air by inhaling airborne contaminants from inside a room and eliminating harmful pathogens using an effective HEPA-13 filter and powerful, class-leading UV-C lamps. Once the air is purified, it is re-released into the room, providing consistently clean and unpolluted air.



How Scarecrow technology works

Scarecrow units are safe for people to be around and can be placed anywhere in a room or workspace, continually working to keep the air inside the premises clean and purified: 24 hours a day, 365 days a year.

Scarecrow’s powerful cleaning process

Indoor air is constantly drawn into Scarecrow’s speaker-like, 7-blade powerful axial fan throughout the day. After being cleansed and purified, the clean air is then released back into the room.


Step 1

Air from inside the room enters the Scarecrow, where its carbon filter removes any odours which are present.’

Step 2

The air then progresses to the hospital-grade HEPA-13 filter within the unit, breaking down and catching harmful pathogens like pollen, dust and mould.

Step 3

This clarified air then advances to Scarecrow’s final cleaning process.

Step 4

Class-leading UV-C lamps work at the optimum level to destroy any remaining pollutants, viruses, odours and bacteria, before releasing 100% purified air.
