The world watches in understandable concern since the reports of the Novel Coronavirus outbreak in Wuhan, China. Tens of thousands of cases have been documented along with many fatalities attributed to the virus. Cases have occurred in many world countries including the United States. The most effective protection against the new strain are the best air purifiers for coronaviruses.
The category of viruses is so named secondary to the physical appearance that includes a crown-like shape created by the proteins that protrude from the main orbital surface. The viruses many strains are attributed to causing colds and the flu along with the more serious Middle Eastern respiratory syndrome known as MERS and the severe acute respiratory syndrome known as SARS. However, the Novel Coronavirus is considered a relatively new strain that is believed to have originated in the live animals sold in Wuhan’s market. Coronavirus is common in bats, snakes, camels and large seafood. The 2019-nCoV variety has also been found in the armadillo-like animal known as the pangolin, which is also sold in Wuhan. The market has since closed and investigation continues as to the specific cause, which remains unknown.

Coronaviruses mutate, which ensures the pathogen’s ability to survive, grow and replicate. The virus found in animals mutates, which enables the pathogen to affect humans. The virus then becomes known as a zoonotic. The virus is easily passed by inhaling the air in the presence of an infected person who coughs or sneezes. However, recently, researchers also discovered that the virus may be transmitted by coming into contact with body fluids. People coming in contact with the virus undergo an incubation period spanning two days to two weeks before experiencing symptoms. Initial symptoms are not unlike having a cold or the flu. Victims experience a sore throat, a runny nose, a fever, coughing and shortness of breath. But, the 2019-nCoV often quickly progress to potentially fatal pneumonia.
In the majority of coronavirus cases, the youngest, oldest and immunity-impaired individuals have the highest risk of developing a serious illness. However, The 2019-nCoV has caused fatalities in people of all ages and in young adults who have otherwise enjoyed optimal health prior to infection. China’s National Health Commission reports that the majority of fatalities occurred in adults over the age of 50. The New England Journal of Medicine learned that the average age of the original 425 patients was 59.
Laboratory testing of the blood and respiratory secretions identifies the 2019-nCoV pathogen. In general, patients are provided with supportive care that includes medications for fever reduction, fluids to reduce dehydration and provide nutrition along with antimicrobial medications to eradicate secondary infections. Physicians in Thailand have achieved success in treating patients with a combination of antiviral and anti-HIV medications. While affordable in many foreign countries, the same treatment regimen in the United States costs thousands of dollars if provided.
Travelers are advised not to go to China. Hand washing for a minimum of 20 seconds is advised in the event that someone comes in physical contact with the virus. Alcohol-based hand cleaners are an option if hand washing is not an option. The Center for Disease Control and Prevention also advises avoiding touching the eyes, nose or mouth before washing hands. Individuals experience symptoms are advised to remain at home. A face mask is optional. But, any household surface may become contaminated with the pathogen. Air purification systems are the ideal option for ensuring that all home occupants remain healthy. But, before deciding on a specific product, the best air purifier for coronavirus must have one or more of the following features:
- HEPA Filters
From the 1940s, HEPA filters have been used in biomedical fields to prevent the spread of airborne organisms. However, the filters vary in performance from simply cleaning air to true HEPA filters designed to eliminate pathogens. In order to be effective against the 2019-nCoV, the device must capably capture particles 0.3 microns in size or smaller. But, to remain effective, the filters must be replaced according to the manufacturer’s recommendations.
- Ultraviolet Irradiation
Ultraviolet light is known to have the ability to kill the majority of bacteria, fungi and viruses. But, to be effective, the air must be exposed to the light for a sufficient length of time in order to eradicate pathogens. Commercial units have a UV lamp directed onto the HEPA filter to ensure elimination.
- Electrostatic Precipitators
The technology uses opposing charges to cause particle adhesion by adding an extra oxygen molecule. The heavy particles then fall onto collection plates. The plates must be routinely cleaned to ensure ongoing efficiency.
- Ozone Generators
The technology adds an oxygen molecule to each O2 molecule of air. The act increases the weight of the particles and causes them to fall. However, O3, or ozone, is known to cause respiratory irritation if the device emits more than 100 parts per billion indoors.
