The website provides several drop-down menus. First, users can choose which mode they want their HVAC unit to operate in: Off, Auto, or On. Thereafter, users can select a premium or regular filter. Then, users can choose whether they have a HEPA air cleaner or not. Finally, users can then choose whether they have a nearby window open.

Based on the selections, CDC will display a meter showing whether users have poor ventilation or better ventilation indoors. The map will also display animated particles to show how far or close they are depending on the user’s selection.

The agency also posted on its website, “Small particles that people breathe may contain virus particles, including the virus that causes COVID-19.”

The CDC recommends avoiding crowded, poorly ventilated spaces if possible.

The CDC also suggests wearing a mask that fits snugly over your nose and mouth if you are in a public indoor setting and have not been fully vaccinated. Even people who have been fully vaccinated are asked to wear masks in public indoor settings in areas with sufficient to high transmission. If a member of your household has a weakened immune system, is at increased risk of serious illness, or hasn’t been vaccinated, you can choose to wear a mask regardless of the level of transmission, the agency said.

The CDC also said that the best way to reduce COVID-19 risk and keep your friends and family safe is to get vaccinated against the novel coronavirus. By receiving a vaccine, the CDC says recipients will better protect those who are not yet eligible for vaccination, such as young children under the age of 5.

The nation’s top infectious disease expert Dr. Anthony Fauci said families who have been fully vaccinated against COVID-19 should “feel good” about gathering for the holidays this year.
