PeruRail implements HEPA filters for air purification on trains to Machu Picchu

PeruRail announced the incorporation of HEPA (High Efficiency Particulate Arresting) filters, an innovative air disinfection and purification system on board its tourist train services to Machu Picchu, to provide its passengers with a safer travel experience, prioritising the best and most modern biosecurity protocols.

“The HEPA filters allow the air inside the cars to be completely changed every 3 minutes, achieving a clean environment and eliminating 99.99% of viruses and bacteria,” said the railway company.


According to PeruRail, this innovative system purifies and renews the air in the trains and uses state-of-the-art technology with four disinfection phases:

1- HEPA (High Efficiency Particulate Arresting) Filters + Activated Carbon: These clean the air passing through the filters and trap any pathogenic elements, achieving a clean and disinfected environment, also eliminating more than 90% of viruses or bacteria.
The air is completely changed every 15 minutes; it passes through HEPA filters, which manage to eliminate 99.9% of viruses and bacteria, including those that cause Covid-19. With this, they achieve pure and safe air, which complies with the strictest hygiene standards.

2- Far UVC lamps: This device emits a light whose wavelength is capable of effectively eliminating certain viruses and bacteria without damaging the skin of exposed persons.
Through the Far UVC lamp, pathogenic elements are eliminated from the filter, as its ultraviolet UVC radiation damages the DNA of numerous microorganisms and prevents them from reproducing.

3- Ionizer: This is a device for environmental cleaning that uses electrically charged particles to improve air quality, as it returns ionized air to the environment, keeping the space protected.
This mechanism generates ions so that the sterilized air that is returned to the environment is ionised. These ions adhere to the positive charge of the particles in the air, such as viruses or bacteria, generating weight so that they fall to the floor and prevent them from remaining in suspension.

4- UVC lamps with Ozone (O3): This is a germicidal lamp mainly used to attack the DNA of microorganisms, destroy their structure and suppress their ability to reproduce and self-replicate.
This phase causes water and ozone to mix in the contact tank. The water mixed with the ozone passes through two UV tubes with extremely powerful lamps that help to treat bacteria, viruses, fungi and algae that have resisted the ozone and comes out completely disinfected.

This programmable phase allows the total sterilization of cars with a flow of ozonized air in high concentrations to guarantee the disinfection of surfaces and spaces that are difficult to access. This process works without the presence of people and is similar to that used in laboratories and/or operating theatres.

“This new ventilation system also meets high international standards and is in addition to all the sanitary measures implemented by PeruRail before the Covid-19 to continue contributing to the revival of tourism, providing safe travel to the most emblematic destinations in the country and, of course, greater peace of mind and confidence to passengers and our employees in the various tourist train services,” said the company.
