Rensair Air Purifiers at Lytchett Minster School | A Case Study
Lytchett Minster School in Dorset is a thriving secondary school and sixth form, educating around 1,500 students (ages 11-18) and employing about 100 staff. Its campus combines historic 17th-century manor architecture with modern facilities, a setting that presents both charm and challenges when it came to upgrading ventilation during COVID-19.
When the pandemic struck, the school leadership sought scientifically grounded solutions to improve indoor air safety. After careful evaluation, they selected Rensair’s portable, hospital-grade air purifiers, considered among the best air purifiers for schools and universities, to support safer reopening and ongoing campus use.
The Challenge: Balancing Safety, Comfort & Practicality
Lytchett Minster School needed a solution to maintain safe indoor air without disrupting lessons. Natural ventilation was limited in winter, and some rooms couldn’t be aired effectively. The school required a system that was quiet, efficient, and capable of protecting staff and students from airborne pathogens.
Seasonal Ventilation Is Not Enough
In the first lockdown, keeping windows and doors open was manageable because of the milder weather. But once winter arrived, relying solely on natural ventilation became unworkable: “students had to wear their coats in class,” recalled the school’s Business Manager, Kieren Hasler. Further, certain rooms due to their layout or location couldn’t receive adequate fresh air. As a result, the school was faced with two unappealing options: stop using those rooms or find an alternative method to clean the air.
Key Requirements for a Purification System
Lytchett Minster needed something more than just an air filter. Their criteria included:
- Coverage of large areas
- Ability to remove and inactivate pathogens
- Highly efficient HEPA filtration
- Quiet operation suitable for use during lessons
These requirements narrowed their options significantly.
Why the School Chose Rensair
Rensair offered scientifically proven air purification, removing up to 99.97% of airborne pathogens. Its plug-and-play simplicity, quiet operation, and ability to cover large spaces made it ideal for classrooms, allowing the school to improve safety and continue teaching without disruption.
Science-Backed Performance
Rensair’s technology has been independently tested in accredited labs and shown to remove or kill up to 99.97% of airborne pathogens, including viruses. Its patented design pairs filtration with UV-C treatment, making it more than just a purifier, it’s a sanitising device.
Simplicity & Ease of Use
For a busy school environment, ease of operation is essential. The staff appreciated that Rensair units are “plug and play” literally: plug in, turn on, and let them run.
Strategic Placement Across Campus
Lytchett Minster installed five Rensair devices in key high-risk zones:
- The Head Teacher’s office and staff meeting area
- A computer room
- The corridor near a photocopier (in the Maths & Science block)
- The main hallway/congregation area
- A large open classroom on the same block
By targeting these critical nodes, they maximised safety without over-investing in unnecessary units.
Results & Reflections
- Rooms that previously could not be used due to poor ventilation are now back in use, with added reassurance from air purification.
- Teachers and students benefit from improved indoor air quality without disruptive noise.
- The school leadership now considers Rensair part of their ongoing pandemic resilience strategy: “Air purification can be complex. It’s an important protective measure,” Hasler noted.
