Having a clean office is more important than ever with the risk of being exposed to COVID when co-workers surround you. Roughly 40 percent of Americans are also working remotely, so it’s crucial to protect your home and space where you’re spending most of your time. Working indoors also poses a considerable threat, with indoor air pollution being one of the leading environmental risks for our health.

 While indoor air quality is five times worse than outdoor air, you need some methods of feeling more protected in your office. Viruses, allergens, and more harmful particles are in the air, and a HEPA filter is one of the best things to eliminate these risks that seep into the office. Air purifiers utilize HEPA filters that trap large and microscopic air particles that can get into our respiratory system and create numerous health issues. An air purifier with HEPA for the office is the best tool you have to increase productivity and create a healthy work environment, so we found the best products to keep you working hard.
