Rensair is a specialist in air purification, protecting and enhancing lives through clean air. Our patented technology, which combines H13 HEPA filtration with germicidal UVC light, was developed to meet the strict standards of Scandinavian hospitals and is independently validated by scientific research laboratories.
Rensair meets the standards for air cleaners recommended by leading authorities including the WHO, CDC, SAGE and EPA.
For companies to thrive, they need physical interaction. Not just talking, but meeting. Personal contact and face-to-face brainstorming stimulate new ideas and champion corporate culture. That’s why most organizations want their staff back in the office, at least on a part time basis.
But some employees are reluctant to return. Anxiety about Covid persists and people have got used to WFH. If companies are to entice employees back, infection control and employee health need to be top of the management agenda.
As the world emerges from lockdown and people start to gather again in indoor spaces, the threat of airborne transmission escalates.The World Health Organization (WHO) now advises that Covid-19 is mainly spread through the air. The CDC also warns that the Delta variant causes more infections and spreads faster than earlier forms of the virus that causes Covid-19.
There is also evidence to suggest that, after a protracted period of social distancing and mask wearing, people have weaker immune systems to defend themselves against the onslaught of respiratory viruses like flu and the common cold, as well as Covid-19 and its variants.
Businesses are rightly concerned about protecting their employees, customers and other stakeholders. As a by-product of that protection, they also want to reduce absenteeism and increase productivity, two further advantages of good indoor air quality:
However, many buildings struggle to achieve the WHO’s recommended air change rate of 10 litres per second per person. It is often an unrealistic expectation, especially in conference rooms with high occupancy levels and back to back meetings.
That’s where portable air purifiers come in to close the gap. But. of course, not all air purifiers are the same.
The CDC recommends portable HEPA filtration units that combine High Efficiency Particulate Air (HEPA) filters with high fan speeds as a preferred option for auxiliary air cleaning. Ultraviolet germicidal irradiation is also cited as a supplemental treatment to inactivate SARS-CoV-2. Other authorities such as the WHO, SAGE and EPA also stipulate that, in the absence of effective mechanical or natural (outdoor air) ventilation, a good air purifier should be based on HEPA and UVC technologies. HEPA filter air purifiers can either work in isolation (single or multiple units) or they can supplement an in-built Heating, Ventilation and Air Conditioning (HVAC) system to eliminate airborne impurities and improve office air standards.
A major new study from Harvard University shows that there is a direct relationship between the amount of ultra fine particles in the air and how people perform in mental tests. The more polluted the air, the worse people perform. Read more..

When it comes to capital cost, a portable HEPA filter air purifier (or multiple devices) tends to be a fraction of the cost of in-built Heating, Ventilation and Air Conditioning (HVAC) systems. A portable air purifier typically has similar energy consumption to a fridge freezer and costs just a few cents a day to run.
With an air purifier using a HEPA type filter, further substantial savings can be made on energy (and associated carbon emissions) from not having to heat or cool fresh air intake. The ongoing savings from the right air purifier can quickly offset the initial capital investment in purified air.
Most indoor air pollution including viruses, bacteria, fungi, mold spores, smoke particles, pet dander, dust mites, allergens, pollen, ultra fine dust particles, and odours.
On the lowest setting, the Rensair unit’s noise level is just 45dBA, an even white noise, equivalent to the recommended white noise level limit for an infant sleep machine. On a Sound Pressure Level (SPL) metre, it sits between ‘whisper quiet’ and ’quiet home’.
