The invention was presented at the Offshore Energy trade fair in Amsterdam on Tuesday.
"It's a large industrial filter about 8 meters (26 feet) long, made of steel ... placed basically on top of buildings and it works like a big vacuum cleaner," company spokesman Henk Boersen told AFP.
The firm describes their invention as the "world's first giant outside air vacuum cleaner," according to AFP.
"A large column of air will pass through the filter and come out clear," Boersen told AFP.
Envinity claims that their prototype can suck in air from a 300-meter radius and about seven kilometers (4 miles) upwards. Citing tests from the Energy Research Centre of the Netherlands, the impressive machine can clean about 800,000 cubic meters (28,000 cubic feet) of air per hour using patented ozone-free ion technology. As a result, the vacuum can filter out 100 percent of fine particles and 95 percent of ultra-fine particles.
As Envinity states, fine particles and ultra-fine particles are indeed extremely harmful to public health, and can be a hindrance to national, regional and local investments and economic progress.
"Without really being aware of it, we breathe in small quantities of toxic particles from the surrounding air 24 hours a day. These are responsible for a great many health problems," Envinity notes on its website.
As EcoWatch observed previously, exposure to poor air quality is the world's fourth-leading threat to human health. An International Energy Agency study found that 6.5 million deaths globally are attributed to poor air quality.

According to Envinity, fine particles, or particles smaller than 10 micrometers, are linked to an increased risk of respiratory and cardiovascular health problems. Ultra-fine particles, which are smaller than 0.1 micrometers, have an even greater impact on public health as they can damage the nervous system, including brain cells and also cause infections in the human body.
These toxic particles are the result of man-made pollution. Unregulated and poorly regulated energy production and use, as well as inefficient fuel combustion, are the "most important man-made sources of key air pollutant emissions," the International Energy Agency stated. Eighty-five percent of particulate matter—which can contain acids, metals, soil and dust particles—and almost all sulfur oxides and nitrogen oxides can be linked back to those sources.
Boersen said that governments, businesses and airports have already expressed interest in the project.
"It might be a cliché, but we hope that we will be able to leave the world a better place than when we found it," Envinity Group co-founder Simon van der Burg told Dutch News.

Accessibility to quality health care has dropped for millions of Americans who lost their health insurance due to unemployment. New research has found that 5.4 million Americans were dropped from their insurance between February and May of this year. In that three-month stretch more Americans lost their coverage than have lost coverage in any entire year, according to The New York Times.

It's going to be back-to-school time soon, but will children go into the classrooms?
The American Academy of Pediatrics (AAP) thinks so, but only as long as safety measures are in place.
Keeping Schools Safe<p>What will safer schools look like?</p><p>In a <a href="https://jamanetwork.com/journals/jama/fullarticle/2766822" target="_blank">JAMA article</a> published last month, <a href="https://www.jhsph.edu/faculty/directory/profile/1781/joshua-m-sharfstein" target="_blank">Dr. Joshua Sharfstein</a>, a pediatrician and professor at the Johns Hopkins Bloomberg School of Public Health, outlined suggestions — many of which are similar to AAP's.</p><p>Remote learning protocols must stay in place, especially as some schools stagger home and in-building learning. If another shutdown needs to occur, children will rely on distance learning completely, so it must be easy to switch to, he said.</p><p>He suggested giving parents a daily checklist to document their child's health. Kids should be screened quickly on arrival and be given hygiene supplies. Maintenance staff should use appropriate PPE and have regular cleaning schedules. A notification system should be in place if a case is identified, Sharfstein recommended.</p><p><a href="https://www.albany.edu/rockefeller/faculty/erika-martin" target="_blank">Erika Martin</a>, PhD, an associate professor of public administration and policy at University at Albany, said nutrition assistance and health services should be included. She called for tutoring programs with virtual options as well as technology access.</p>
Supporting Staff<p>Teachers and staff will be affected by safeguarding measures, noted <a href="https://directory.sph.umn.edu/bio/sph-a-z/rachel-widome" target="_blank">Rachel Widome</a>, PhD, an associate professor of epidemiology and community health at University of Minnesota.</p><p>"In order for all of the in-school precautions to work well, we'll be asking a lot of teachers and staff," Widome told Healthline. In addition to their usual workload, they'll now be asked to monitor mask-wearing, ensure children are keeping distance, and be aware of any symptoms.</p><p>Along with Sharfstein, Widome called for an increase in financial support. More employees will likely be required so teachers and staff members can keep up with the added demands.</p>
Should Kids Go Back?<p>While these guidelines may help get some schools to reopen, many people don't think children should go back to school over fears they could contract the disease and spread it to other vulnerable family members like grandparents, infant siblings, or their parents.</p><p>In a <a href="https://pediatrics.aappublications.org/content/early/2020/07/08/peds.2020-004879" target="_blank">Pediatrics</a> commentary, <a href="https://www.md.com/doctor/william-raszka-md" target="_blank">Dr. William V. Raszka, Jr.</a>, an infectious disease specialist at The University of Vermont Medical Center, argued that schools should open because school-aged children are far less important drivers of COVID-19 than adults.</p><p>But he says the risk and benefit is not equal among all students ages 5 to 18.</p><p>"Elementary schools are arguably higher priority for face-to-face schooling, since younger children are at lower risk for infection and transmission, and since parental supervision of younger children's distance learning may be particularly challenging," added Sorensen, who penned a <a href="https://jamanetwork.com/channels/health-forum/fullarticle/2767411" target="_blank">June article in JAMA</a> with reopening tips. "That means middle and high schools are more likely to emphasize distance learning."</p><p>Specific student populations, such as special education students and students with disabilities, would also benefit greatly from more time spent in face-to-face environments, Sorensen said.</p>
What Parents Can Do<p>Parents should ask for and receive frequent updates from schools about plans for the fall. They should also be informed about plans if and when COVID infections are identified, Sharfstein said.</p><p>"I'd like to see parents investing now, during the summer, in doing things that can slow and stop the spread of the virus in their communities," Widome said.</p><p>"Now is a good time for kids to practice wearing masks and get used to them as they may be wearing them for longer stretches if school starts up in person," Widome suggested.</p><p>She recommends parents try different mask designs and materials to see what children are more comfortable wearing.</p><p>"If you are using cloth face coverings, it's good to have extras on hand," Widome added.</p><p>Parents should model healthy behavior at home and while out in public — another thing that could affect how well children adapt to reopening practices, Sorensen said.</p><p>"Children may want to know more about face coverings," added <a href="https://www.linkedin.com/in/leescott/" target="_blank">Lee Scott</a>, chairwoman of the Educational Advisory Board at <a href="https://www.goddardschool.com/" target="_blank">The Goddard School</a>. "Dramatic play, such as creating or wearing a face covering, may help some children adjust to this concept." Schools can also show children photos of what faculty members look like in their masks so the students are familiar with that appearance.</p><p>Johns Hopkins University recently released its eSchool+ Initiative, a slew of resources surrounding education during the pandemic. These include a <a href="https://equityschoolplus.jhu.edu/reopening-checklist/" target="_blank">checklist for administrators</a>, report on <a href="https://equityschoolplus.jhu.edu/ethics-of-reopening/" target="_blank">ethical considerations</a>, and a tracker of <a href="https://equityschoolplus.jhu.edu/reopening-policy-tracker/" target="_blank">state and local reopening plans</a>.</p>
