Will be returning to office in the next couple of months, I will be meeting with individuals in a closed door office and have weekly staff meetings with a team of about 6-7 people, and occasionally be in larger group settings in a conference room for trainings. I need a recommendation for a good air purifier for my office which is about 900 cubic feet. I intend to wear a KN95 for the individual meetings and small staff meeting and run the air purifier, and wear my 3M Aura for the conference room meetings, I’m having a lot of anxiety about this. Suggestions?
