Using an air purifier can reduce the risk of Covid-19 infection. Some are also wearable.

Proper ventilation of indoor living spaces helps prevent various diseases and reduce the spread of viruses. This is common sense, not rocket science. The fresher and cleaner the air we breathe, the better for our health. 

The use of portable air purifiers at home and in the office, as well as the new wearable air purifiers that we can carry with us, can reduce airborne viruses and bacteria in living and working spaces. 

Wearable air purifiers can help clean the air in your personal space-which is about a square meter of space around us, or the area around when you stretch your arms-in other indoor and crowded spaces such as elevators, Airports, airplanes, and public transportation, etc. 

Coronavirus particles belong to the particle size range captured by the HEPA filter. The HEPA filter is a filter in some air purifiers that can capture particles of 0.01 micron and larger. Portable air purifiers with HEPA filters-also known as air purifiers-definitely help reduce the risk of Covid-19 airborne. 

Dr. Gregory Poland, an infectious disease expert at the Mayo Clinic, said that indeed, air purifiers can often help. "The more the air exchange, the cleaner the air, the lower the risk," said Dr. Poland. “On its own, it’s not satisfactory, so what we’re doing, as we’ve discussed for months [during the pandemic], is layered protection. Let’s ensure the air at home if We have someone coming over, as safe as possible. This means HEPA (High Efficiency Particulate Air) filters."

In the opinion of the Polish doctor, it does not need to spend a lot of money to buy high-quality and high-efficiency particulate air filters. Portable air filters are designed to filter only the air in a single room. However, they cannot remove all air pollutants. 

"The virus does not pass out of the body on its own. The virus must be attached to something. Tiny mucus, a piece of dust in the environment-this is how it spreads. The HEPA filter captures these and fixes them there. It does. It means that you have to replace the filter at appropriate intervals," said Dr. Poland. The filter does not kill the virus, but exchanges clean air more quickly to remove the virus. 

"For the HEPA filter, it is electrostatically connected to the filter itself, so it cannot circulate in the air, which is why it is so important to replace the filters and replace them correctly," said Dr. Poland.

indeed. Dr. Poland reminded us that the use of air purifiers and filters may be another tool to reduce the risk of Covid-19, while continuing to wear masks, maintain social distancing and use hand sanitizers when with others or in public places. Every layer of protection adds to our safety. 

Here are some tips on how to use a portable air filter:

Place the air purifier in the room where you spend the most time, or where disadvantaged groups spend the most time 

In order to reduce the risk of airborne transmission, please direct the airflow of the air purifier so that it does not directly blow from one person to another

Dr. Poland also recommends flu vaccination during this season, which is particularly important as part of the Covid-19 protection plan. "The flu vaccine is very safe and the effect is moderate," he said. “It will reduce your anxiety about what these respiratory symptoms might mean. It will prevent you from entering the quarantine area. It will prevent a surge in demand for the medical system, which is more likely than flu for those who may actually have Covid-19. "

The working principle or operating efficiency of an air purifier is not obvious, simply because it is not visible. Both portable and wearable air purifiers work by emitting charged molecules or atoms (called ions).

These ions transfer charge to particles, such as those that carry influenza viruses. These invisible particles are located in the human breathing zone. The charged particles repel each other, and the infected particles are eventually pushed out of the breathing zone.  

Let's take a closer look at the physics behind ion formation and the intangible health benefits of air purifiers. 

To understand the working principle of air purifiers, we first need to understand the effects of positive and negative ions on human health. The most important benefit of negative ions is that they can remove allergens in the air, such as pollen, mold spores, bacteria and viruses. In addition, they can remove dust, pet dander and cigarette smoke from the air.

The harm of positive ions to human health is called ion poisoning. Atmospheric ions have a negative impact on human health, happiness, efficiency, mood and mentality.

On the other hand, the positive effects of increased levels of negative ions in the air on human health include enhancing relaxation, reducing stress levels, reducing fatigue, reducing irritability and depression, and enhancing the immune system. A strengthened immune system helps fight Covid-19.  

It is easy to make negative ions at home. Burning beeswax candles help clean the air, generate negative ions, and help reduce allergies and asthma. Running the indoor fountain will generate force or energy, and the falling water will cause the neutral particles in the air to split, thereby releasing electrons to attach to other air molecules, thereby generating negative ions. The candles and fountain are beautiful, calm and relaxing. 

This air purifier is very suitable for desktop computers. It is equipped with a HEPA filter and a micro USB cable. According to the manufacturer, it can filter 99.97% of dust, pollen, cigarette smoke, odors, mold spores and pet dander.

It can filter particles as small as 0.3 microns and larger, and filter PM 2.5 (pollution rate) air pollution to help improve overall health and improve air quality in small rooms.

It is portable and weighs 550 grams. It can easily cover an area of ​​about 10 square meters. It will automatically shut down after 8 hours of use. It has a blue LED night light. Negative ions bring efficient air filtration.

Through the use of pulse cutting-edge technology, the wearable purifier releases a large amount of negative oxygen ions. Negative ions kill harmful bacteria, viruses, molds, and decompose harmful gases such as cigarette smoke, peculiar smell, and formaldehyde and benzene released from auto parts. Negative ions promote metabolism, activate cells, refresh the brain, and relieve motion sickness. 

Unlike portable air purifiers, wearable mini air purifiers are designed in the form of a necklace and do not require filters, which is very convenient. They come with a USB cable and can be easily replaced anywhere.

They are stylish, portable, and easy to operate with just an on/off button. Wearable air purifiers are designed to clean the air in your personal space by releasing millions of negative ions.

This is a small sample of my favorite wearable air purifier:  

GHmarine portable mini USB air purifier is a personalized and wearable air purifier necklace. It emits more than 6 million negative ions, which can capture pollutants in your personal space, including second-hand smoke, bacteria, or allergy-causing particles.

When you take public transportation, airplanes, elevators, offices or other enclosed places with poor air quality, you can wear it as a necklace to create a cleaner area for the air around you.

You can also place it flat on your desk to create fresh air bubbles around you. Putting negative ions on the bedside table can improve the quality of sleep. According to the manufacturer, it can be charged for half an hour and kept charged for about 20 hours. This product is suitable for adults and children.

This unique blue heart design is completely different from other wearable air purifiers. According to the manufacturer, this air purifier necklace can reduce the harm of PM2.5, second-hand smoke, formaldehyde, and various germs and bacteria.

It can be used for public transportation, crowded tourist places, restaurants, bars, elevators and any other enclosed spaces. Enough to replace any other necklace.

This USB portable wearable air purifier can be worn as a necklace or placed on a desk. It weighs only 30 grams, which is as small as the AA battery. It helps clean up your personal space through negative ion purification.

At night, it can stand on the bedside table to purify the personal space of about one square meter around you, just like other personal wearable air purifiers. This is why they are "personal." 

From above, a small white light will be displayed when it is turned on, a red light will be displayed when it needs to be charged, and a green light will be displayed when it is fully charged. The on/off button is located at the device button and charging port. 

This portable wearable air purifier uses advanced negative ion technology. In addition to purifying pollen, bacteria, and second-hand smoke, it can also continuously release healthy negative ion airflow.

It can clean your personal space and protect it from surrounding bacteria, mold and other pollutants that are harmful to your health. It produces 300 million negative ions per cubic centimeter, allowing you to breathe fresh air wherever you go. It also looks good.

Using air purifiers and filters may be another tool to reduce the risk of Covid-19, while continuing to wear a mask when you are with others, maintain social distancing, wash your hands frequently, and use hand sanitizer.
