Environmental, Social and Governance

Rensair’s purpose is to protect and enhance lives through clean air.

Like pure water from the tap, or hygienic food from the shops, people expect clean air in buildings and shared spaces.

More than an expectation, it’s a human right.


Clean air means quality of life

As advocates of indoor air quality, we also uphold quality of life. Nowadays, the focus is on coronavirus and airborne infection control, but there is a broader societal pollution problem. Nine out of ten people breathe air with pollutant levels that exceed the WHO’s guideline limits. This can have adverse impacts on the six body systems: brain; nervous; cardiovascular; respiratory; endocrine; and renal. Polluted air has been linked to many serious health risks, including neurological disorders, Alzheimer’s, cancer, and diseases of the heart, lungs and kidneys. The WHO estimates that reducing annual average fine particulate matter (PM2.5) concentrations from 35 μg/m3 to their guideline level of 10 μg/m3 could reduce air pollution-related deaths by around 15%

Our role is to help minimise such health problems by focusing on the indoor environment, where concentrations of pollutants are two to five times higher than outdoors. Not only can that protect and enhance lives: the by-products of better health are higher energy, improved productivity and heightened cognitive functions, all of which contribute to a better life.


Giving back to communities

One of Rensair’s core values is that we give back. We are a force for good, actively supporting charitable causes, disadvantaged groups, community programmes and sustainability initiatives.

Any organisation with official charitable status will automatically qualify for heavily discounted pricing, proportional to the number of units required. We understand that many charities have suffered greatly during the pandemic so, even if your budget is stretched to the limit, please get in touch and we will do whatever we can to help.

Examples of charities that have benefited from Rensair air purification include the Red Cross, Citizens Advice Bureau, Ronald McDonald House Charities, Muscular Dystrophy Support Centre, Shrewsbury Food Hub, SSAFA, and Kirrie Connections.

At Rensair, we believe that we must earn our social licence to operate. As experts in clean air and indoor air quality, it follows that we feel strongly about air pollution. Within our own business, that demands practising what we preach.

Minimising our carbon footprint

From our manufacturing site, our product is transported to stocking & distribution centres in the UK, Europe and USA. Having conducted a materiality assessment we have identified that, although sea freight is the least damaging form of freight forwarding, it represents a significant proportion of our overall carbon footprint. That’s why we have opted into a carbon offset programme, taking positive action to limit our climate impact and hasten the transition to a clean energy future.

Via our logistics partners, Flexport, we contribute $6.50 per tonne of carbon emitted to Carbonfund.org in order to fully offset our carbon footprint. That money goes towards the Russas-Valparaiso Projects in the Amazon rainforest of western Brazil. Protecting 70,000 hectares of tropical rainforest, the goal is to mitigate the release of approximately 3 million tonnes of carbon dioxide emissions.

Eutraco, our distribution partner in Antwerp, Belgium, received the TransportMedia logistics building of the year award 2021. The facility is the very first carbon and energy neutral warehouse put into service by a 3PL logistics solutions provider.


Low power, high added value

The Rensair unit uses only 160 – 220W of power, depending on the airflow level. This is equivalent to a modern day fridge-freezer found in most residential kitchens.

Using Rensair can significantly reduce energy costs for business premises. In cold climates, any intake of outdoor air must be heated. Since Rensair air purifiers are so effective at cleaning the air, the intake of fresh, outdoor air can be reduced, thereby saving on ventilation and heating bills. Similarly, in hot climates, less fresh air means less energy on ventilation and air conditioning.


Designed to be recycled

The Rensair air purifier is built to very high standards, with the aim to last a lifetime if properly serviced and maintained. The bulk of materials used to manufacture it can be recycled.

Much of the unit – including the casing, motor and fan – is made from steel, which is infinitely recyclable. The fan unit contains a copper coil, which can also be recycled, avoiding landfill and slowing the depletion of natural resources. Another significant constituent material is rigid plastic, which is suitable both for closed loop (same product) and open loop (different product) recycling.

The air purifier’s HEPA filters are made from borosilicate fibreglass, housed within an aluminium casing. The filters can be treated as scrap metal and the fibreglass, rendered harmless by UVC disinfection, is simply burned off in the aluminium melting process. The UVC lamp bulb can be recycled like any other type of fluorescent bulb.

Rensair is currently working on establishing agreements with recycling organisations in key user countries, such that used consumables can be returned via pre-printed labels direct to appropriately qualified recycling stations, thereby ensuring that none end up in landfill.
