Indoor air quality is a critical need for hospitals
Covid-19 has been devastating for hospitals and care homes around the world, highlighting the inadequacy of ventilation in the healthcare sector. Many hospitals still struggle to meet ventilation guidelines (eg 6 air changes per hour in UK NHS hospital wards). This so-called ‘structural under-ventilation’ is mainly due to inadequate existing ventilation systems in older hospitals and prohibitive retrofit costs, not to mention the disruption that a new HVAC installation would entail.
Rensair’s portable hospital grade air purification units are being used by hospitals in many countries to close this ventilation gap. A clean air environment delivered by Rensair allows for a return to full capacity and a resumption of key services, including AGPs, Spirometry, Endoscopy and Radiology as well as to keep poorly ventilated wards open.

Air purifier validation tests
The UK National Health Service tested Rensair’s bio-efficiency using the Liverpool Bio Validation Protocol, confirming its ability to achieve a 99.9% (Log 3) particle reduction in 34.2 seconds. CFD modelling in an NHS dental suite demonstrated post-AGP Log2 particle reduction in under 2 and a half minutes, independent of where the unit was placed in the room.
Rensair’s air purifiers are also independently validated by scientific research laboratories, including Eurofins, Norconsult, and Oslo University Hospital.
In a test by the Danish Technological Institute to determine Rensair’s performance in reducing the concentration of MS2 bioaerosols as a proxy for SARS-CoV-2, a particle reduction rate of 99.98% was recorded in 15 minutes and above 99.99% in 30 minutes. Furthermore, a second test reported 100% elimination of virus particles on the filter, with zero traces detected.

Portable HEPA filter air purifiers to protect patients and staff
Rensair’s portable, hospital grade HEPA filter air purifiers can be a quick fix, supplementing existing integrated ventilation systems to eradicate air contaminants. High performance (min 99.97% efficacy), cost-effective (fraction of the cost of a new HVAC system) , multi-tasking (viruses, bacteria, allergens), and instant to instal (simply plug and play).
The WHO recommends air purifiers to supplement integrated ventilation systems while the UK SAGE committee, in its November 2020 report on air cleaning devices to combat SARS-CoV-2 transmission, recommends two air purifier technologies: fibrous HEPA filter and germicidal UVC light. This is supported by a new report on infection resilient environments, commissioned by the UK government’s Chief Scientific Adviser and published by the Royal Academy of Engineering.
Rensair’s medical grade air purifiers use a patented combination of HEPA filtration and UVC – supported by a powerful fan – to both trap and destroy viruses, rendering the HEPA filter totally safe for easy maintenance.
NHS Confederation
Rensair is proud to be an Associate Member of the NHS Confederation and supports their aim by providing education and expertise on hospital-grade air purification to combat airborne viruses and bacteria. As a result, we hope to improve infection control standards across the NHS and facilitate a return to full capacity, thereby reducing the backlog caused by the pandemic.
Care homes
Clean air is key to controlling infectious diseases in nursing homes
Pathogens like Covid-19 exist in aerosols emitted by ill people when they breath, talk, cough or sneeze, which remain suspended in the air in poorly ventilated indoor spaces. When the World Health Organization eventually announced that Covid-19 was mainly airborne, the focus rightly shifted from cleaning surfaces to ventilation and clean air.
Tragically, the consequence of Covid-19 – exacerbated by poor ventilation and indoor air quality – has been devastating in many countries. According to the UK Care Quality Commission (CQC), more than 39,000 care home residents in England alone died with Covid-19 between 10 April 2020 and 31 March 2021.
Air purification for dental practices
Minimise fallow time, maximise patient throughput
It’s a fact: poor ventilation extends fallow time.
Depending on your practice’s Air Change per Hour rate, post Aerosol Generating Procedure (AGP) downtime can be as much as 30 minutes. That severely limits the number of patients you can see per day.
In a standard 30m3 dentist surgery room (4x3m with normal ceiling height), Rensair’s portable air purifier can change the air 18 times per hour (18 ACH), eliminating air pollutants and halving fallow time.
Trusted by the NHS and private dental surgeries across the UK, our innovative design combines a HEPA filter with germicidal UVC light to trap and inactivate a minimum of 99.97% of airborne particles.
Instant. Portable. Affordable. Proven. The practical air purification solution for delivering clean air and maximising patient throughput.

The preferred hospital grade air purifier for NHS Trusts
Originally developed to meet the strict requirements of Scandinavian hospitals, Rensair’s medical grade air purifiers are fast becoming the preferred choice for the NHS, a breath of fresh air boosting indoor air quality throughout, from wards to operating theatres.
Rensair has worked closely with NHS Estates teams and NHS Infection Prevention and Control teams at various Trust hospitals on their implementation of our products. This has led to reopening of poorly ventilated closed wards, reduced fallow times between appointments and increased patient throughput in many departments
One Trust was quoted £140,000 per ward to increase the airflow of their existing HVAC system to meet the official guidelines. They decided that buying Rensair’s portable air purifiers was both a significantly cheaper, less disruptive and technically superior air quality solution.
Rensair is the only air purification company to be an Associate Member of the NHS Confederation, supporting their aim by providing education and expertise on air purification to combat airborne viruses and bacteria. As a result, we hope to improve infection control standards across the NHS and facilitate a return to full capacity, tackling the backlog caused by the pandemic.

Air purification for dental practices
Hospital Dental Treatment Room tests
Rensair’s patented air purification system combines a hospital-grade H13 HEPA filter with an ozone-free UVC light to trap and inactivate particulate matter, including pathogens.
ESI Group recently completed in-situ modelling on the Rensair air purifier within a Birmingham NHS Hospital Dental Treatment Room. Using advanced computational fluid dynamics, the results confirmed very effective air circulation and removal of aerosols generated from AGP procedures. The directional flow of air is critical to the dentist’s own safety. Deposition and near patient flow field tests demonstrated that the Rensair unit draws aerosols downwards, thereby protecting dentists from airborne contamination.

Clean air is the NHS’s most powerful weapon against Covid
The impact of Covid on the NHS has been devastating and it has now been reported that it could take up to five years to clear the backlog. People are calling for a bold, transformative approach to resolve this crippling issue. Clearly, a raft of measures is needed, both financial and operational. If the health sector is to live long term with Covid, it needs to cover all the bases: not just the complex issues like human resources and capacity increases, but simpler issues too – like hospital grade air purifiers to remove air contaminants and improve indoor air quality… more

Ground attack alone will not defeat drug-resistant bacteria
Of course, Covid is not the only threat that can be quelled with clean air. We can predict what will happen with drug-resistant bacteria and we know that it requires a multi-faceted defence system that includes air purifiers to deliver clean air.
Norovirus is a case in point. With particles approximately 27-38 microns in diameter, which are easily trapped by HEPA filters, it is known to spread in aerosol droplets that are created when infected children or adults vomit and/or have diarrhea. Despite that knowledge, preventative measures still focus on fomite cleaning and hand washing, even though, globally, norovirus results in a total of $4.2 billion in direct health system costs and $60.3 billion in societal costs per year… more
