Coronavirus is a recent global outbreak that has caused a threat to human lives all around the world. With its first identified case in Wuhan, China, in December 2019, this virus had claimed the lives of many to date. Recently, on 11th March 2020, the World Health Organization (WHO) has declared this virus pandemic. This virus has caused a lot of fear, panic, and have affected both the social and economic lives of many people.
The Coronavirus is mainly spread through respiratory activities like sneezing and coughing. Common symptoms related to this virus include cough, fever, and shortness of breath. It usually takes around five days for the symptoms to appear after a person has been exposed to the virus. There is no specific treatment or vaccine to cure this virus as of now, but efforts are being made to eradicate it at the earliest. As per a study, this virus can survive in the air for several hours.
People have been advised to take preventive measures in order to protect themselves from being infected. This includes washing hands, using hand sanitizers, covering mouth while coughing and sneezing, maintaining a distance of about 1 meter from other people, staying indoors, and a self-isolation for 14 days for those who have been tested positive of the virus.
How do air purifiers help?
Another way of preventing yourself from the Coronavirus is by using air purifiers at home. It is very important to breathe quality air while staying indoors. Air purifiers may help or prevent you from the virus by trapping harmful germs and viruses causing agents present in the air. In order to filter airborne viruses such as the COVID-19, an air purifier with a Super HEPA filter is needed since the size of the Coronavirus is as minute as 0.1 microns. Air purifiers that are equipped with SUPER HEPA FILTERS can efficiently capture airborne virus particles which, once trapped, cannot remain infectious for long nor multiply. This allows for the circulation of clean air and helps in keeping our immune system strong. This does not, however, mean that air purifiers can be used to cure a person who has been infected by the virus. It is just a way of preventing ourselves from the virus by ensuring good air quality inside our homes.
Various manufactures have started donating air purifiers to different countries in order to help control the spread of the Coronavirus. Companies like Aller Air have also recently sent some air purifiers to China in order to help reduce and control of the virus. Besides having features like the Super HEPA filter, these air cleaners are also equipped with an ultraviolet bulb which effectively kills any airborne bacteria, germs, and viruses such as the Coronavirus Disease 2019.
Categories of air purifiers
The main purpose of an air purifier is to filter out any dust particles, smoke, pollens, or any airborne pollutants. However, not all air purifiers are the same since different air purifiers have different abilities. While some are capable of filtering large particles like hair, dirt, and dander, while some are capable of trapping tiny particles like odor, germs, mold, and viruses.
Air purifiers can be divided into different categories depending on the type of technology used. Here are the two most commonly categorized ones:
HEPA air purifiers
HEPA air purifiers are one of the most common and popular types of air purifiers. They are very effective in removing particles like mold, pollen, dust, and other ultra-fine large air particles. This type of air purifier consists of filters made of fiber-like material with a number of tiny holes, which is strategically placed to trap pollutants that are bigger in size so that they cannot pass through these holes. As air passes through the filter, harmful particles are destroyed by a process of interception, and fresher and purified air comes out of it. As air passes through the filter multiple times, it gets cleaner. HEPA filters are also designed to trap and eliminate 99.7% of air particles as small as 0.1 microns.
Ultraviolet air purifiers
The ultraviolet air purifier is a product of inspiration from hospitals that disinfects patients’ rooms and other important areas using a special kind of ultraviolet light bulbs. This type of air purifier uses ultraviolet light to remove harmful bacteria, pathogens, and viruses from your home. Ultraviolet air purifiers are very compact, and they can filter out any polluted air at home through a UV light chamber. The UV lights in the purifier destroy 99.9% of particles as well as break the DNA of the pathogens that prevents them from reproducing further.

1. Can air purifiers protect you from the Coronavirus?
Yes, air purifiers can protect you from the Coronavirus. However, this does not mean that all air purifiers can protect you from the virus. Most ordinary air purifiers are only capable of trapping microns of .3 or larger in size, whereas the size of a coronavirus is approximately .1 microbes. Thus, only air purifiers that have a super HEPA filter system are capable of filtering microns of .1 in size. Also, air purifiers that are equipped with a UV bulb can effectively kill many airborne bacteria, germs, and viruses such as the corona disease in 2019. The UV light present in the purifier helps to neutralize molds and damage the DNA. Air purifiers, however, do not assure a cure from the virus. This means that a person who has already been infected by the virus cannot be cured by using an air purifier.
2. Can masks protect people from the Coronavirus?
No, wearing masks does not mean that you will be immune to the virus. There is a wide misconception that wearing a mask will protect you 100% from the virus. The main purpose of a face mask is to help trap droplets, which is the main mode of transmission of the virus. WHO has also stated that masks are mainly meant to be worn by people who have been infected with the virus. It reduces the chances of the virus from being transmitted to other people.
3. What is an air purifier?
An air purifier is a device that is specifically designed to clean the contaminated air at home. It comes in both small and large units that can be attached to an HVAC. An air purifier removes any impurities present in the air, such as dust, odors, pet dander, and smoke. It usually consists of a fan and a filter or multiple filters that can suck in the contaminated air and circulate fine air out. Different air purifiers also consist of different purification technology like UV light, ionic technology, high heat, exhaust system, or HEPA filters.
Having an air purifier at home ensures you and your family a healthy air to breathe in. Besides protecting you from various germs, viruses, odors, dust, and other particles, air purifiers also help in keeping your lungs healthy. You just need to remember that all air purifiers do not serve the same purpose and so you need to purchase the one which best fits your situation.
