Exciting news:

On 24 June, the Clean Air Fund hosts its inaugural Clean Air Hub at the National Theatre.

This will be a full day of conversations, practical sessions, and cultural events focused on prompting action for clean air.

It will bring together leading experts on climate change, public health, finance and business as well as artists and cultural figures to consider one question: what does it take to make clean air a reality for everyone?

We think that question needs an answer.

The science is known. Air pollution is one of, if not the single biggest environmental risks to UK public health.

It is associated with elevated risk of heart disease, stroke, lung disease, dementia, and cancer.

We spend 90% of our time indoors, where the air can be two to five times more polluted than outside, but which is a uniquely controlled environment where we can clean the air.

And we know how to do this.

Air filtration significantly reduces indoor particulate matter. The evidence is settled, and now the barrier is a lack of awareness and urgency.

Events like the Clean Air Hub bring the right people into one room to direct the conversations and the initiatives that will eventually lead to change.

And you can support us directly and hear a uniquely interesting story.

On 19 June, the day after national clean air day, we are hosting our own free event: a conversation with Jonas Grau Thomsen, the world's first exoskeleton test pilot.

Our trustee John Muir will talk to Jonas about technology, limits, and inclusion. It promises to be very interesting.

Why is a clean air charity hosting a talk by the world's first exoskeleton test pilot? It is a fair question. Here is our answer.

At the Corsi-Rosenthal Foundation UK, we donate air cleaners to (among others) people who are clinically vulnerable or have lung conditions such as Asthma.

For many such people air quality is not a simple inconvenience or nice to have.

It is a potential barrier to participation in life that the rest of us take for granted.

Going to school. Going to work. Accepting visitors. Using public transport.

Simple things that can be complicated by consideration of air quality.

Jonas Grau Thomsen has lived experience of navigating a world that wasn't built with disabled people at the front of mind.

As a young child, he lost the use of his legs. He then went on to become the world's first exoskeleton test pilot, pushing the boundaries of what technology can do for people with disabilities.

This seemed relevant to us. Firstly, a simple and cost effective technology can mitigate the barrier created by poor air quality.

Secondly, as we enter the AI era, the question of how people with clinical vulnerabilities or disabilities can harness technology to level the playing field is highly relevant.

On Friday 19 June, at 20:00 BST, Jonas joins our trustee John Muir for a free online conversation. They will talk about technology, limits, and inclusion. They will discuss the AI era and whether it creates new possibilities and how those can be seized.

Clean air is good for all of us. Even those of us who don't have any life limiting conditions benefit from it hugely. For those who do suffer clinical vulnerabilities, lung disease or other disabilities, clean air can be a significant factor in widening their access to the world. That is what we are working towards, and it is why this conversation matters to us.

There will be audience interaction so please come ready to answer questions or share opinions.

This event is free. A voluntary donation of £10 is welcomed but not required.

Back in December we were brainstorming a fundraiser and had the idea of a promise auction - asking supporters if they would offer a skill or service in exchange for a contribution to the Corsi-Rosenthal Foundation UK.

That idea led us somewhere unexpected.

It led us to Jonas Grau Thomsen.

Jonas lost the use of his legs as an infant and became wheelchair bound. Despite this, he went on to become the world's first exoskeleton test pilot and an important voice in the world of assistive technology.

As we sit on the cusp of the AI era it became clear that a conversation about harnessing the power of technology to increase inclusion would be something our supporters and beneficiaries would find useful.

On Friday 19 June, at 20:00 BST, Jonas will join our trustee John Muir online for a free, live conversation. They'll discuss technology, societal limits on participation and why the limits other people impose on that are not necessarily your own.

Many of the people we support are clinically vulnerable. They know what it feels like to move through a world where their needs were not always foremost considerations.

The question for us all is the same: how do we help more people participate fully in the world?

We believe clean air is part of that answer, and that's one reason we do what we do.

This talk will be an opportunity to explore other technology and its impact.

This event is free but we invite a voluntary donation of £10 to support our work if you can afford it.

If not, you are still very welcome to attend.
And bring someone who you think would enjoy it.

You've probably heard that clean air could save millions of lives.

But recent research from scientists at the Stockholm Environment Institute, working with the University of York and published in The Lancet Planetary Health, has added a crucial new insight.

Contaminated air has a compounding effect on other issues known to worsen public health, including poverty, pre-existing health conditions, and access to healthcare.

To put this plainly, the same level of air pollution causes more harm in a deprived community, or one with poorer access to healthcare, than in a more affluent community.

Contaminated air makes poverty more dangerous.

This is one of the reasons we donate air cleaners to schools and to people who are clinically vulnerable.

It is also why we focus on those in greatest need, because we know that the public health burden of environmental pollution, and the ability to mitigate it, is not evenly distributed.

If clean air is most needed where people are most vulnerable, then that is where we should focus our efforts.

This research reminds us that clean air isn't just an environmental issue.

It is a health equity issue.

Clean air in schools is now UK Government policy. Good progress.

H13 in early guidance is understandable.

But CADR depends on form, fit and flow.

High-airflow CR Boxes with MERV filters can exceed some H13 units.

Keep the door open to innovation.

Measles is back in the UK. Vaccines come first, but indoor air matters too.

The WHO has confirmed that the UK has lost its measles elimination status after sustained transmission and thousands of cases since 2024.

This is a sad and preventable moment, and at its heart is a simple fact. Vaccination rates haven't been high enough.

As well as being potentially serious, measles is one of the most infectious viruses known to medicine. A single person can infect 15 to 20 others in a susceptible group. And infectious virus droplets can persist for hours after a source of infection has left a room.

UK elimination status has come and gone over the last few years. But measles doesn't come and go, it embeds itself unless it is stopped and poses a particular risk to young children, pregnant women, and people who are clinically vulnerable.

We've got to be clear here, if we want the UK to regain its measles elimination status, route one is to increase vaccination rates above 95% with both doses of MMR.

That said, measles, like many viruses, including COVID, flu, spreads through the air. The same indoor air that spread the COVID pandemic is where measles gets a foothold.

The quality of our indoor air matters.

A layered approach to infection control matters.

Vaccination is the essential foundation.

But good ventilation and filtration can remove infectious bioaerosols. We know that.

Not everyone can tolerate the MMR vaccine. Those people are reliant on everybody else doing what they should do.

That means getting vaccinated, but it also means other layered protections, including clean indoor air.

Otherwise, our future will be one of entirely avoidable outbreaks of diseases like measles.

And measles can kill and disable people, and leave you vulnerable to other infections, sometimes for years.

So we think a healthier future looks like this:

✅ MMR coverage consistently at or above 95% pre-school.
✅ Every public place, and particularly every school and healthcare setting, with simple ventilation standards supplemented by filtration wherever necessary.
✅ Public health leaders talking about clean indoor air in the same breath as vaccination or handwashing or anything else which is known to slow the spread of disease.

Measles will exploit any gap that we leave in our defences, but we know that we can close those gaps. Not doing so is a choice.

Vaccinations is how we stop measles, but clean indoor air is how we reinforce the wall.

A new health trend is taking off. It’s not new. Germans have famously been doing it for years. It’s called house burping.

The idea is simple. Every so often you open every window and door and let the air flush through. There’s real science behind this.

We spend about 90% of our time indoors. Over time, we load that air with pollutants, bioaerosols, semi-volatile organic compounds, cooking aerosols, cleaning aerosols, and of course, CO₂.

CO₂ matters.

In one study, opening windows and doors reduced the concentration by about 60%. We’re generally advised to keep levels below around 1,000 parts per million, which is still roughly 70% higher than typical outdoor air. So ventilation does make a difference.

But there are limits.

If you live near a busy road, in a polluted area, or during a wildfire event, opening the window could actually let pollutants in. It can increase the concentration of PM2.5 in your indoor air.

There are also energy and comfort considerations. It’s not always pleasant to throw open the doors and windows in winter.

So perhaps a more layered approach makes sense. Not just house burping, but air filtration too.

For some people, filtration isn’t a nice-to-have. It’s closer to an inclusivity measure.

At the Corsi-Rosenthal Foundation UK, we focus on donating and promoting air filtration to those most in need, including schools and the clinically vulnerable.

So the answer isn’t either/or. Open the windows, probably avoiding peak traffic times. Burp your house. But alongside that, consider filtration.

It’s encouraging that clean indoor air is being recognised as more than just a wellness trend. It’s public health.

Long live house burping. Just consider doing it with filtration too.

£1 per classroom per day.

That's what it costs to protect children from 5 health conditions: asthma, infections, heart disease, learning loss & long-term brain health.

The Corsi-Rosenthal Foundation UK donates air cleaners to schools & clinically vulnerable people.
