H13 vs H14 Filtration

June 20, 2022

There are a wide range of systems available on the market that show differing levels of efficacy in capturing airborne viruses and bacteria. But which class of HEPA filters – H13 vs H14 filtration – have a higher long-term efficacy?

In this post, we provide an overview of why air filtration is an important measure to mitigate the risk of airborne contamination and airborne viral transmission, how HEPA filters can reduce this risk, and which class - H13 vs H14 filtration – has shown the highest overall efficacy in achieving this.

Air Filtration in Schools

January 05, 2022

Here we explore the benefits of adopting air filtration and purification systems in school classrooms, alongside recommended measures such as social distancing, hand washing and face mask use. Effective air filtration can help provide protection against Covid-19 and improve indoor air quality more broadly.

UVC Air Cleaners & their Efficacy

January 02, 2022

UVC air cleaners are often advertised as being able to “sterilises the air” and that the “air is disinfected” through the use of the UVC light in an air cleaner. But is that true? This article discusses the pros and cons of UVC air cleaners as an infection control measure.

Exploring airspace development for the NHS

December 16, 2021

Airspace development refers to building new structures in the ‘air-rights’ on the roof of an existing building. Whilst this is not a new idea, airspace development is becoming an increasingly popular opportunity for developers to create new spaces in dense cities such as London, and changing policies and perceptions in government and local authorities means there is now more scope to explore the option.

Researchers find way to filter coronavirus particles out of the air

December 15, 2021

Researchers find way to filter coronavirus particles out of the air.The discovery could improve the safety of "surge wards" in the NHS which can often lack the ability to change the air with a high frequency and prevent patient-to-healthcare worker transmission.

EN1822 Classification – Why it matters

March 07, 2021

Since the emergence of Covid-19 and global efforts to minimise the spread of infection throughout populations, there has been a renewed focus on determining what measures can be adopted to mitigate the risk of airborne transmission of respiratory viruses, including Covid-19, in a range of close proximity indoor settings.

Particle Pollution – A Chemical Pollution Cocktail

February 04, 2021

Particulate pollution is an important contributor to both outdoor and indoor air pollution. These tiny particles are inhaled into the lungs and the smaller they are, the deeper they go with the smallest penetrating as far as the bloodstream. They are responsible for a host of health impacts, from asthma attacks to premature death

The Dangers of Dust in the Dental Laboratory

February 03, 2021

A recent study analysed the size range of particle which dental technologists may come into contact with during the course of their work. A number of blocks of composites used in dental prostheses were ground and the dust thus generated analysed. The size range of this dust extended down to the UFP level, proving that a potential health hazard does exist in the dental laboratory setting.

Infant Mental Development and Air Pollution

February 03, 2021

Indoor air quality is an often overlooked source of exposure to pollution that can cause ill health. Far more attention is given to outdoor pollution. In fact, indoor air pollution may cause nearly 3% of the total global burden of disease, according to the World Health Organization. It makes sense – after all many of us spend up to 90% of our time indoors.

Increased Hospital Admissions due to Air Pollution

February 03, 2021

What is the increased hospital admissions resulting from air pollution? It is well known that both short and long-term exposure to air pollution increases the rate of hospital admissions. To quote just one study, from researchers at Harvard School of Public Health Health, every 10 microgram increase in long-term PM2.5 exposure caused.

Chemicals in School Science Labs

February 03, 2021

Learning science, including chemistry, is an important part of primary and secondary education. However, practical chemistry involves chemicals, some of which may be hazardous, particularly in the hands of young children. So how do we protect children and young people from chemicals in school science labs, while not denying them the fun of experiments and the useful experience it gives them?
