LG has officially unveiled a new portable air purifier face mask. The PuriCare Wearable Air Purifier is the first of its kind smart face mask that is touted to help address the shortage of disposable masks which resulted due to the ongoing COVID-19 pandemic.

According to LG, the new wearable air purifier is also designed to replace inconsistent or less effective homemade masks worn by some people.

LG’s new wearable air purifier will be showcased at IFA 2020 in September. The South Korea-based tech giant will make the PuriCare available by the fourth quarter of 2020, with details of pricing to be revealed at the time of its launch.

LG first announced the smart mask back in July, with The Korea Herald reporting that the company would donate 2,000 wearable air purifiers to a university hospital in Seoul. A company executive claimed that LG hoped that the mask would make it easier for first responders and medical staff to wear masks for prolonged periods.

LG’s wearable air purifier uses two H13 HEPA filters to purify the air, similar to how a regular air purifier operates. The face mask features dual fans with three-speed levels that automatically speed up or slow down to assists with air intake and reduce resistance while exhaling, respectively. Additionally, LG claims that the PuriCare’s respiratory sensor can detect the cycle and volume of the wearer’s breath and adjust the fans accordingly.

COVID-19 Vaccine

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
