Can air purifiers prevent the spread of disease in your home?


AThe ir filter was once the rage before COVID-19 entered our lives, and for good reason: The air inside our home can be dirtier than the air outside. But the pandemic redefined what many of us think is dirty air, because indoor air is largely believed to be pay more attention when it comes to catching viruses or bacterial infections than outdoor air. Sales companies Air purifier are currently positioning their products as being able to reduce the risk of infection in the home, which is quite a highlight. But does air purifiers really reduce the risk of viruses and other airborne diseases?

“The short answer is yes,” said Timothy Brewer, MD, professor of medicine and epidemiology at UCLA. “There is at least a lab the data to suggest that these filters are capable of removing virus-infected respiratory droplets from the air. “

Most air purifiers use a high efficiency air filter (HEPA) –Similar filter types are found on the plane. “HEPA filters choose things that are less than three microns [in size], and the virus is usually much smaller than that number, ”said Dr. Brewer. “But filters work in removing respiratory droplets containing viral particles from the air because the electrostatic force forces the particles to clump together and act on the filter.” In other words, viruses that are too small will pass through filters with particles large enough to be captured by them.

Therefore, there is a compelling argument for adding an air purifier in your home to help reduce the spread of disease among your family members. “When it comes to dealing with airborne viruses, CDC guidelines and others are helping to increase the ventilation rate in your home – so basically, dilute the air of whatever someone is bringing in, ”said Molekule CEO and Co-Founder. Jaya Rao |. “Most of us can’t really modify our Heating, Ventilation and Air Condition or HVAC systems, and while you can open windows, if you’re sitting in really cold conditions. [or hot, or fire-polluted] weather you may also be uncomfortable doing that. “

She further notes that many of us have increase the amount of cleaning products We are also using it during a pandemic, which can also leave potentially harmful chemicals suspended in the air in their homes. “Those are not good for breathing either, so you might have solved one problem but you created another,” says Jaya. “Air purifiers can also help reduce the burden of those chemical pollutants.”

With all that said, no experts have supported it forgo security protocols advocate turning on one or two air purifiers. The key word, when it comes to what air purifiers can do against the risk of infection, is “reduce” —they are not a safe substance. “[Air purifiers] is not a replacement for [pandemic safety measures]So you can’t stick a filter in the house and then invite all your friends over and have a giant party – it doesn’t work that way, ”says Dr. Brewer. “While they can offer some benefits, that doesn’t eliminate the need to maintain physical distance, cover the face, and minimize contact with people outside of the home or live nest. your.”

And if you can’t buy an existing air purifier, Dr. Brewer says you can take other steps – as Jaya also mentioned – to improve your indoor ventilation. “The first thing to do is open the window if you can, ”he said. “Placing a fan in a window and drawing air out is also a cheap way to increase ventilation to reduce dust particles. You can also wear a mask indoors [if company is present]. Those are things people can do instantly at no cost and can reduce exposure. ”
