When I started my 30-day office air purifier testing journey, I didn’t expect to feel such a noticeable difference in my workspace. After spending eight hours daily in a corporate office with recirculated air, I began experiencing afternoon headaches and fatigue. The problem? Poor indoor air quality. Research shows that office workers spend approximately one-third of their day in environments with suboptimal air circulation, making the best air purifier for the office an essential investment.
