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.
