Portable school air purifier

Rensair is a specialist in air purification, protecting and enhancing lives through clean air. Rensair meets the standards for air cleaners recommended by leading authorities including the World Health Organization, CDC, SAGE and EPA.
Our patented air purifier technology, which combines H13 HEPA filtration with germicidal UVC light, was developed to meet the strict standards of Scandinavian hospitals.

Education

Indoor air quality is critical for school classrooms and university lecture halls

 

Covid-19 presents a significant problem for the education sector. The WHO asserts that the chief threat of transmission is airborne. In crowded indoor spaces, like in schools, that threat is amplified, particularly when students are in the same room together for an extended period of time or when enhanced aerosol generation is likely, for example through singing, projected speech and aerobic activity.

However, the scale of the problem is not matched by unlimited budgets. Many school and university buildings are magnificent in terms of architecture, yet chronically under-ventilated. Others are listed, demanding bespoke and costly retrofits. Competing priorities, such as structural repairs, may make a complete overhaul of ventilation systems an impossibility.

Education

Portable air purifier for classroom applications

Fortunately, HVAC systems are not the only solution. Portable air purifiers can do an effective job, either enhancing existing ventilation systems or working in isolation.

They must be high performing, hospital-grade air purifiers with a powerful fan to ensure adequate air circulation, HEPA air filtration to trap particles and UVC light to destroy the harmful ones. Residential air purifiers will not deliver the same results, despite over-inflated marketing claims.

The investment is just a fraction of what it would cost for an in-built ventilation system, with no disruption for installation. Through air purification, further savings can be made by reducing energy consumption for heating or cooling fresh air intake.

EDUCATION

The role of CO2 monitors

Several governments around the world are focusing on CO2 monitors to help track the evolving risk of Covid-19 transmission in indoor spaces such as schools and universities. Most guidance – such as that from the UK HSE –  advises that ventilation needs to be addressed when CO2 levels exceed 1,500 parts per million (ppm) and the HSE’s long-term exposure limit (8-hr reference period) recommendation is 5,000ppm.

However, a CO2 sensor is the equivalent of the canary in a coal mine.  It will warn when there is inadequate indoor air quality, yet it stops short of recommending any practical solution once a ventilation deficiency has been identified. In the absence of ample ventilation, air purification can be a practical and effective solution, as recommended by the WHO, CDC, SAGE, CIBSE and other authorities.

  • Not just children’s health but their safety

    Unlike other technologies, there are no harmful by-products. Rensair is perfectly safe.

    Rensair’s UVC lamp is 254nm +/- 1nm, the optimal wavelength for destroying viruses without creating any ozone. The lamp is also totally enclosed and therefore 100% safe to use in occupied rooms. It destroys all virus particles on the HEPA filter, also rendering it safe for maintenance.

    The unit is robust, with a metal casing that prevents children from tampering with it or knocking it over. It is CE, ROHS and ETL certified.

  • Reducing transmission risk in heavy occupied spaces

    In some shared spaces within a typical school, the building’s ventilation system is highly unlikely to achieve the World Health Organization’s recommended clean air delivery rate of 10 litres per second per person.

    The likelihood of airborne virus transmission is amplified in heavily occupied indoor spaces, particularly if people are in the same room together for an extended period of time or when enhanced aerosol generation is likely, for example through singing, projected speech and aerobic activity. This applies to libraries, science labs, school halls and gyms. Air purification can restore air quality in such crowded places and protect students against infection.

  • Healthy air means enhanced learning in classrooms

    A major new study from Harvard University shows that there is a direct relationship between the amount of fine particulate matter in the air and how people perform in mental tests. The more polluted the air, the worse people perform.

    ● By sustaining 20% lower air pollution levels in the classroom, the development of a child’s working memory can improve by 6%. (Philips Foundation and the University of Manchester).
    ● Better indoor air quality boosts academic performance – maths and reading scores go up, and pupils are measurably more attentive in class. (The Economist).

Rensair Solves King’s College School Wimbledon Air Purification Challenges

For King’s College School, Wimbledon, Rensair’s hospital-grade air purifiers were a breath of fresh air. The school acquired several units to improve air quality within classrooms, limit the spread of Covid-19 and protect the school against further outbreaks. The device is suited to learning environments as it is quiet and its portability means it can easily be moved between classrooms to remove airborne contaminants where occupancy levels are high.

Lytchett Minster School

Lytchett Minster School chose Rensair’s portable, school air purifiers to solve their indoor air quality needs. The risk assessment identified spaces that could not be ventilated with fresh outdoor air. The school assessed different HEPA air purifiers and relied on science to determine which fit their needs. The areas that were high risk are now functioning to capacity, and there’s reassurance that Rensair air purifiers are mitigating the risk of viral spread.

A practical guide to clean air inside the school gates

  • Questions

  • How many air purifiers are typically needed for one classroom?

    In general, one Rensair air purifier will suffice as it can clean up to 560m3 of air per hour. A typical 240m3 school lab, larger than a classroom, would have clean air within half an hour.
    Get in touch with Rensair’s technical experts for a free consultation to define the right solution for your school.

  • How can indoor air quality in a classroom be measured?

    The air purifiers have a built-in, atmospheric particulate matter sensor. It feeds real-time data to a gauge on the control panel that indicates the level of air quality in the room, allowing users to switch to high, medium or low settings accordingly. It measures miniscule PM2.5 particle concentration, made up from dust, bacterial spores, viruses, allergens, smoke, outside air pollution and much more.
