There is an urgent call for action on ventilation in schools - to slow the spread of Covid-19 - when pupils return, in September.
Six education unions have written to England's education secretary, warning of a steep rise in Covid and "long Covid" when pupils return to classes.
Better airflow measures would limit disruption and sickness, unions say.
The Department for Education said: "We want to ensure schools are both safe and comfortable for students and staff - and good ventilation has consistently been part of government guidance.
"Areas where ventilation is poor should be proactively identified so that steps can be taken to improve fresh air flow if needed."
And pointing to a £1.75m pilot scheme in Bradford said it was working to identify cost-effective ways to reduce transmission in communities, and assess the most effective use of proven air purification technologies in school settings.
The government-funded research involves 30 primary schools in Bradford, West Yorkshire, but could be rolled out nationwide if successful.
Ten of the schools will be given high-efficiency particulate air (HEPA) filters and 10 will get UV purifiers.
The other 10 will be a control group with no devices, researchers said.
SARS-CoV-2 belongs to the same group of viruses that cause colds and influenza. The use of AIRsteril units in call centres and offices at an NHS Trust has been shown to reduce the incidence of illness-related absences; particularly reported cases of colds, coughs, and influenza, as well as reducing other chest and respiratory problems.
The Ozofresh Eclipse Pro is a heavy-duty yet entirely portable ozone-generating machine that inactivates Coronavirus in just 60 minutes. Crucially it destroys the virus on both hard and soft surfaces, as well as in the air, working on areas such as blinds, drapes, and carpets – all the same areas that are targeted by fogging. These videos explain a little more about how Ozofresh works.
It can be easily picked up and moved from room to room, protecting all types of indoor areas. The machine is versatile enough to decontaminate different sized rooms even up to 200m2. Ozone leaves no chemical residue whatsoever and no by-products. Rooms can be used again immediately after treatment.
Do you have lettings in your school? Ozofresh can be used as a great way to quickly and effectively decontaminate an area that has had public access making it safe for when students have to return.
The Eclipse Pro requires no training to use, anyone can simply plug it in, close the door and leave it to sanitise every surface. And it’s a one-off purchase. No consumables to buy means no ongoing costs, and it can be used as often as needed. Establishments can also lease the machine for a very affordable monthly payment.
Be assured that the power of ozone is proven with laboratory testing. Its virus-destroying properties are well documented against a range of pathogens. And the renowned Nara Medical University in Japan has confirmed that it specifically kills the coronavirus causing COVID 19. Our ozone generators produce the levels of ozone required to be effective.
