If you have asthma, the advice of the Centers for Disease Control and Prevention (CDC) is to avoid your triggers. Common asthma triggers include:
Cleaning and disinfection agents
Asthma can also worsen or flare up with sinus infections, allergies, pollen, acid reflux, influenza (flu), colds, and respiratory syncytial virus (RSV).
An air purifier can be a worthy investment for the reduction of allergens and asthma triggers. It can capture particles that carry viruses and bacteria that cause cough and colds.
Air purifiers are typically placed inside the home, but there are also those that can be worn. They may not eliminate the coronavirus per se, but they can get rid of asthma triggers and likely lower the risk of infections.
What is a wearable air purifier?
Now, will a wearable air purifier clean the air? This 2015 article by the Wall Street Journal reports the device may help clear a variety of test particles from the air in lab tests. But scientists say there’s no proof they have any health benefit in real conditions.
However, wearable purifiers (typically worn in the neck) have become popular. Take the ible Airvida as an example. The Consumer Electronics Show (CES), the world's largest electronics trade show, awarded it with the Innovation Award in 2020 for providing impressive protection against airborne virus and pollutants.
Microchem Laboratory in the U.S. also said this Taiwan-made wearable ionic air purifier had a virus removal rate of 96.31% in 1 minute.

The international laboratory certification report says ible Airvida can remove up to 99.9% of air pollutants, like viruses, bacteria, pollen, and formaldehyde.
It can also eliminate PM2.5, which is considered as “the pollutant with the most health impact of all commonly measured air pollutants” because it can penetrate deep into the lungs when directly inhaled.
How does a wearable air purifier work?
When you wear a personal air purifier, a shield of healthy negative ions is created around your face. The negative ions then quickly act against the positively charged particles in the air.
What they do is attach themselves to the airborne particles, such as dust, bacteria, viruses, pollen, smoke, and pet dander. Then the airborne particles become bigger and heavier until they finally fall to the ground, and you can no longer inhale them.
Design-wise, technology has evolved, too. Gone are the chunky, bothersome devices hanging around your neck. The ible Airvida comes in patented, sleek, and low-profile designs that look like trendy neck pieces.
Just keep in mind this advisory from the Department of Health (DOH): Wearing a personal air purifier cannot replace wearing a face mask to stop catching and spreading the COVID-19 virus.
