Truth About COVID"},"content":{"rendered":"

Air purifiers are said to capture and kill viruses, such as COVID-19. Is this a fact? While the short answer is surprisingly <\/span><\/span>YES<\/span><\/span><\/strong> , we'll further dignify that answer with the following scientific basis.<\/span><\/span><\/em><\/h3>\n

A couple of things you should know first is that:<\/span><\/span><\/p>\n

The COVID-19 virus is <\/span><\/span>close to a 0.125 micron size<\/span><\/span><\/a> (125 nanometers). Viruses this small may not be easily filtered from the air through a standard filter.<\/span><\/span><\/p>\n

Hence, if you want to keep a safer indoor environment free from suspended viruses, use a <\/span><\/span>trusted air purification brand<\/span><\/span><\/a> with the right technology.<\/span><\/span><\/p>\n

Air Purifiers featuring <\/span><\/span>HEPA filters<\/span><\/span><\/strong> can filter contaminants <\/span><\/span>down to 0.3 microns<\/span><\/span><\/strong> .<\/span><\/span><\/p>\n

Furthermore, high performance UV-C LED Lamp, such as in <\/span><\/span>HisoAir<\/span><\/span><\/a> , sterilizes and eliminates organisms and viruses. Basically, the UV light unfolds the protein coating of the virus, effectively inactivating it.<\/span><\/span><\/p>\n

From here, let's elaborate.<\/span><\/span><\/p>\n

How are Airborne Diseases Transmitted?<\/span><\/span><\/h2>\n

In October 2020, the Centers for Disease Control (CDC) released its stance on <\/span><\/span>how the Covid-19 virus is transmitted<\/span><\/span><\/a> .<\/span><\/span><\/p>\n

\n

It says: \"the virus can be transmitted in particles and small droplets lingering in the air for a few minutes to even hours\".<\/span><\/span><\/p>\n<\/blockquote>\n

This means the CDC agrees with the airborne transmission of the virus through suspended aerosols or splatters.<\/span><\/span><\/p>\n

Add to that, many people today tend to work-from-home or stay indoors due to the increasing number of COVID cases, lockdowns and curfews. This may render poor ventilation and air quality as more people are cramped up in homes.<\/span><\/span><\/p>\n

And hence, the odds of spreading communicable diseases indoors increases due to poor air movement.<\/span><\/span><\/p>\n

3 Ways Covid-19 Spreads Through Airborne Transmission<\/span><\/span><\/h3>\n

There are <\/span><\/span>3 ways under which COVID-19 airborne transmission can happen<\/span><\/span><\/a> according to the CDC:<\/span><\/span><\/p>\n

    \n
  1. Enclosed areas<\/span><\/span><\/strong> - when a person is exposed in an enclosed space right after an infectious person has left that place.<\/span><\/span><\/li>\n
  2. Extended exposure with harmful particles<\/span><\/span><\/strong> - being exposed to suspended droplets in the space.<\/span><\/span><\/li>\n
  3. Poor ventilation or inadequate air handling units<\/span><\/span><\/strong> creating suspended respiratory particles and droplets.<\/span><\/span><\/li>\n<\/ol>\n

    This leads us to believe that air purification systems such as air purifiers, disinfection machines and air cleaners play a vital role in cleaning what we breathe in.<\/span><\/span><\/p>\n

     <\/p>\n

    How Do Air Purifiers Work?<\/span><\/span><\/h2>\n
    \"how
    how air purifiers work<\/figcaption><\/figure>\n

    Air purifiers are equipped with several filter technologies to sanitize and clean the air from pollutants, suspended particles, allergens and viruses.<\/span><\/span><\/p>\n

    This means it doesn't only remove the particles by filtering them, it also sanitizes and kills viruses.<\/span><\/span><\/p>\n

    Air purifiers may feature HEPA filters, activated carbon, ionizers or UV light, or a combination of all. The combination of filters determines what type of particles are exactly eliminated from the air. Some types of air cleaners only trap air contaminants, while others are designed with filters that kill and neutralize bacteria, viruses and foul smells.<\/span><\/span><\/p>\n

    HEPA Filters and the Coronavirus<\/span><\/span><\/h2>\n

    Okay, so a lot of people get really confused and misinformed whether HEPA filters can capture small particle sized viruses, such as the Coronavirus.<\/span><\/span><\/p>\n

    HEPA filters can remove 99.97% of particles in the air down to the size of 0.3 microns. The COVID-19 is between 0.06 microns to 0.14 microns in diameter.<\/span><\/span><\/p>\n

    This happens through Diffusion. <\/span><\/span>According to a scientific study from NASA<\/span><\/span><\/a> , HEPA filters can virtually capture 100% of particulates.<\/span><\/span><\/p>\n

    Turns out, the Coronavirus is so small and light that it gets bounced around when hitting gas molecules.<\/span><\/span><\/p>\n

     <\/p>\n

    \"How
    How the Coronavirus<\/figcaption><\/figure>\n

    How the Coronavirus \"fly\" in a random, zigzag pattern through the Brownian movement<\/span><\/span><\/p>\n

    Due to this zigzag motion, whenever the virus travels through the HEPA filter, they get stuck on its fibers.<\/span><\/span><\/p>\n

    This means, particles can be trapped in HEPA filters, even down to the size of 0.1 microns, including the COVID-19 virus. Once it gets trapped, the HEPA filter holds the viruses captive so they cannot be brought back in the air.<\/span><\/span><\/p>\n

    But are the viruses killed? Coronavirus on a HEPA filter may virtually last <\/span><\/span>48 to 72 hours<\/span><\/span><\/a><\/strong> before it dies or inactivated.<\/span><\/span><\/p>\n

    How Does UV light Work in Killing Viruses Like COVID-19?<\/span><\/span><\/h2>\n

    Another type of air cleaning feature is the integration of UV light. UV radiation is detrimental in killing and eliminating bacteria and living microbes. However, it also depends on:<\/span><\/span><\/p>\n
