Dyson purifier hot + cool formaldehyde: The £700 air purifier that tackles heatwaves and hay fever
Over the last few years, we've seen a big rise in home improvement and DIY, a penchant for viral candles, and a surging number of flights booked as 2025 is predicted to be biggest ever summer for travel. It's a random mix of topics with one thing in common: air pollution.
Leading doctors have warned that 99 per cent of the population are breathing in 'toxic air', and air pollution has been declared a public health crisis here in the UK, possibly leading to 30,000 preventable deaths this year alone.
It's not just us adults impacted by bad air quality. Recent NHS England data shows that in some parts of the country, air pollution is linked to 33 per cent of childhood asthma cases.
But it's not all doom and gloom, as there are several ways that we can ensure we're breathing clean air. If you want to purify your air at home, providing a better quality of living for you and your family, we may just have found the ticket.
Enter the Dyson purifier hot + cool formaldehyde, the brand's bestselling air purifier (plus fan and heater). It's designed to clean the air not only of the usual particles picked up by purifiers with a high efficiency particulate absorbing (HEPA) filter, but also to grab all formaldehyde-based resins that come from plywood and fibreboard, insulating materials, paint, wallpaper, varnishes, and some household cleaning products.
This is no small task: formaldehydes are 500 times smaller than particles of 0.1 microns (10 microns is the limit for the naked eye) and to be efficient specifically at catching this chemical, Dyson created an intelligent formaldehyde sensor that's gel-based and will accurately catch and destroy it at a molecular level without confusing it with other volatile organic compounds.
Is hayfever a problem in your house? Dyson's clever purifier also captures and removes the microscopic particles which may cause allergies, acting as a powerful shield against pollen, dust, pet dander and mould. When paired with a great vacuum, you're ready to tackle pollen season head-on.
But these are all huge claims, and so we tested this purifier to find out if it could really clean our air.

This 10-year plan may be the last chance to save the NHS
The 10-year plan for the National Health Service that Sir Keir Starmer is expected to publish in the next few days is likely to be a somewhat incoherent document. From the advance publicity, it would seem to have a lot of disconnected ideas in it, some good, some not so good and some irrelevant. The government hopes that weight-loss drugs will offer the hope of a big advance against obesity-related illnesses – but this comes after new figures raised concerns about their safety. If large language models can speed up the development of new pharmaceuticals, so much the better. But we remain sceptical about whether supermarkets ought to be recruited into policing their customers' calorie intakes. What will decide the success or failure of the NHS over the next decade, however, will be the design of the structural reforms to the service. Wes Streeting, the health and social care secretary, has made a good start in two respects. He has welcomed private-sector providers to help deliver NHS services free at the point of need, and he has taken an axe to the central bureaucracy of NHS England. The test for the 10-year plan will be the extent to which it brings in further changes to incentives throughout the NHS so that it becomes responsive to patients. Sir Jim Mackey, the new chief executive of the NHS, says many of the right things. 'It feels like we've built mechanisms to keep the public away because it's an inconvenience,' he says in his first interview since taking up the post three months ago. He says of the current NHS: 'It takes forever. It costs a fortune. We need to 'de-layer it' because it's expensive, it slows decision-making down, it de-powers people who need to make decisions.' The sentiment is right, but again, some of his ideas seem better than others. We are not convinced that using patient satisfaction surveys to decide how much money NHS trusts receive is going to work. The evidence of reform under the last Labour government was that the mere existence of competition from private-sector providers had a dramatic effect on the performance of NHS units. Already, there are the very early signs that the extra resources put into the NHS are bearing fruit, less than 12 months after the change of government. Luke Tryl, the opinion pollster for More in Common, reported on BBC's Newsnight on Friday that people in focus groups are starting to report positive experiences of the NHS for the first time since the pandemic. 'If there is a bright spot for the government, it's the NHS,' he said. One of the biggest challenges for Sir Jim and Mr Streeting, however, is more political than structural. They have to send the starkest message to doctors: please do not go on strike; take responsibility; show leadership; it is up to you to make the NHS work, because if it cannot be turned round this time, then it probably is the end of this model of healthcare. Sir Jim appears to understand this. He says that his 'big worry' is that if the NHS cannot deliver a service that is better at listening to patients – the particular example he gave was maternity care – 'we'll lose the population; if we lose the population, we've lost the NHS; for me, it's straightforward: the two things are completely dependent on each other.' He is absolutely right. Universal healthcare free at the point of need is a noble idea, but it desperately needs Labour's reforms to work if it is to survive.

I had a stroke two years ago and STILL can't swallow – help!
Got a health-related problem? Send it to Zoe, email below ASK DR ZOE I had a stroke two years ago and STILL can't swallow – help! OUR resident specialist and NHS GP, Dr Zoe Williams, shares her expert advice. Today, Dr Zoe helps a reader who is suffering from total dysphagia and wants to know which treatments are available. Advertisement 2 Dr Zoe Williams helps Sun readers with their health concerns Credit: Olivia West 2 This week a reader still does not have the ability to swallow following a stroke two years ago Q) FOLLOWING a stroke two years ago at the age of 69, I have total dysphagia and have been peg tube fed since. Everything else is back to normal except the ability to swallow but despite doing all the exercises, given by the Speech and Language Therapy team, nothing has worked. Neuromuscular electrical stimulation therapy is private and expensive. Is there any other treatment available? A) Dysphagia is the inability to swallow, which is why you have been fed via a tube into the stomach. Advertisement I'm sorry to hear that you haven't seen improvement despite support from SALT. NMES aims to retrain the nerves and muscles, and SALT exercises increase effectiveness. But it lacks sufficient robust evidence at the moment to be rolled out. However, it can be used as part of clinical trials or audits. A newer NHS-supported treatment, pharyngeal electrical stimulation, targets the throat's pharynx region. It aims to 'rewire' nerve pathways. Clinical trials (eg, the PHADER study) show it improves swallowing safety and reduces aspiration risk in stroke patients. The NHS is also currently investigating transcranial magnetic stimulation (TMS) aimed to reactivate swallowing centres in the brain. Advertisement Other therapies include Botox if muscle stiffness is an issue and surgery to dilate the oesophagus. Do request a multidisciplinary reassessment (neurologist and SALT) to explore your options. And do ask about NHS trials. Send your questions for Dr Zoe to: health@

Really appreciate it and made me feel way less alone going thru it all. 'And as ever, thanks to our amazing NHS.' Her message comes as a second amber heat health alert in two weeks came into force on Friday. The alert, which covers London, the East Midlands, South East, South West and East of England, will last until 6pm on Tuesday. The UK Health Security Agency (UKHSA) has also issued a yellow alert for Yorkshire and Humber and the West Midlands for the same time period, with the agency warning of significant impacts across health and social care services.
