Which air purifiers are best for reducing the spread of COVID-19?

Answer:

Some portable air cleaners (or "air purifiers") can help remove microbial particles, i.e., viruses (such as the coronavirus that causes COVID-19), bacteria and fungi. These devices can be part of a strategy for protecting people indoors when used along with other recommended practices. Many of these air cleaners can also effectively remove smoke particles and odors. Keep in mind that ventilating with clean, outdoor air (which can be done by opening a window, for instance) is always the best way to improve indoor air quality.
