Study: Air purifiers don’t protect you from disease and health

A recent study found that air filtration systems, or “air purifiers,” do not prevent disease. Air purifiers are designed to filter pollutants and impurities that pass through the air.

The study was conducted by researchers at the University of East Anglia in the United Kingdom, and its results were published in a press release issued by the university on November 17.

Researchers found that air filtration systems did not reduce the risk of viral infection.

The team looked at technologies such as air purification, germicidal lamps and ionizers.

They looked at all the available evidence and found little. This supports the claim that these technologies can make the air safe and not spread respiratory or digestive infections.

Professor Paul Hunter from the University of East Anglia said: “Air purifiers are designed to filter pollutants as they pass through the air. When the Covid-19 pandemic hit, many companies and governments – including the NHS, British Army, New York Municipal and German government-regional offices are investigating the installation of such technologies to reduce airborne virus particles in buildings and small facilities.

benefits and costs

“But air treatment technologies can be expensive. So it makes sense to weigh the benefits and costs and understand the current capabilities of these technologies,” he added.

The team looked at evidence of whether air purification technology could make people immune to airborne respiratory or gastrointestinal infections – infections that spread through the air.

They analyzed evidence of microbial infections or symptoms in people who were and were not exposed to air-handling technologies in 32 studies, all of which were conducted in settings such as schools or nursing homes.

“The types of technologies we consider include filtration, germicidal lamps, ionization and any other method to safely remove or inactivate viruses in the air you breathe,” said researcher Dr. Julie Brainard.

“In summary, we found no strong evidence that air treatment technologies protect humans,” he added.

“Our findings are disappointing, but it’s important for public health decision-makers to get the full picture,” he stressed.

airborne diseases

Airborne diseases, also known as airborne diseases or airborne diseases, are diseases that can be contracted simply by breathing.

Airborne diseases spread when people with certain types of infections cough, sneeze, or talk, spraying nasal and throat secretions into the air. Some viruses or bacteria fly and hang in the air or land on people or other surfaces.

When a person breathes in airborne pathogens, they can take up residence in the body. Bacterial infection can also occur when someone touches a surface that contains bacteria and then touches his or her eyes, nose, or mouth.

Because these diseases are airborne, they are difficult to control.

Examples of airborne diseases
