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 from wildfires and odors. Keep in mind that ventilating with clean, outdoor air (which can be done by opening a window, for instance) is typically the best way to improve indoor air quality.

We also discuss and compare the main types of filters, including fibrous air filters (including true HEPA vs. HEPA-type filters), UVGI filters, electrostatic filters and ionizers (which are often used in personal or "wearable" air purifiers), filters for removing odors, DIY air cleaners, and humidifiers (including information about whether they can be used with air purifiers and how to avoid potential exposure to heavy metals emitted by humidifiers).
