Is coronavirus worse than the flu? The short answer is yes, with COVID-19 proving to be much deadlier and contagious. The symptoms are proven to be more impactful during flu season, and the threat of being exposed to the coronavirus is higher while you’re spending more time indoors during the winter. In addition to preventing and contracting COVID, we should also be mindful of the flu, making it even more essential to take care of ourselves and our families.

Flu symptoms and coronavirus are different, but air purifiers can be part of the solution for both. The flu and COVID viruses have similar airborne particle and droplet sizes that spread through the air, and HEPA filters expertly eliminate these particles. Air purifiers clean the air from viruses, germs, and air pollution that can quickly get into your respiratory system and damage your health. With the deadly risks during flu season and coronavirus pandemic, we’re here to help and provide recommendations that will keep you and your family safe.
