Ventilation is one of the first steps to mitigating against the risks of Covid-19 airborne aerosol transmission. As the health and wellbeing of our guests and teams continue to be of paramount importance to us, we have partnered with Rensair to provide this patented solution across some of our hotels, using the most advanced technology with documented efficacy by independent scientific laboratories to decrease air pollution.

Here, we find out more about this air purifying solution…

Why is air purification so crucial to health and wellbeing?

Clean air has never been more important. There is an increasing awareness of air pollution and the health benefits of good air quality, and SARS, MERS and now Covid-19 have shown the huge impact of not having the right air quality procedures in place. Rensair delivers the highest possible air standards, with an air purification unit that was originally developed for Scandinavian hospitals, to meet their strict air quality requirements.

Tell us more about your system…

It was developed 18 years ago by Henrik Hendriksen, a highly experienced Danish ventilation engineer, and the units have been providing air purification in hospitals for more than 15 years. We provide tailor-made air purification solutions as well as risk mitigation strategies against Covid-19 airborne transmission.

How exactly does it work?

The Rensair air purifier consists of a germicidal ozone free UVC lamp placed in the centre of a cylindrical high-quality HEPA13 filter, to not only capture but also inactivate viruses and bacteria trapped on the filter surface. The constant UVC illumination of the entire filtration area ensures a continuous disinfection process, resulting in a safer product to operate and maintain, and ensuring no live bacteria or viruses exist on the filter.

So essentially there are two components to this – the HEPA filter and the UVC illumination?

Yes, that’s right. A High-Efficiency Particulate Air (HEPA) Filter is composed of a mat of randomly arranged fibres, with diameters that must satisfy certain levels of filtration efficiency. Common standards require that a HEPA air filter must remove (from the air that passes through it) at least 99.95% of particles whose diameter are equal to 0.3 micron. Our filtration efficiency increases for particle diameters both less than and greater than 0.3 microns, and captures pollen, dirt, dust, moisture, bacteria, virus and submicron liquid aerosol.

UV is divided into three types with reducing wavelengths and increasing energy. They are UVA, UVB and UVC. For UV sterilization, only UVC has high enough energy to effectively kill microorganisms. Short-wavelength ultraviolet (or UVC) light is used to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA. This leaves microorganisms unable to perform vital cellular functions. UVC is used in a variety of applications, such as food, air, and water purification.
