It doesn't get the same attention as diet, exercise, and mindfulness, but air quality can have a big effect on wellbeing. Coway's Mighty purifier can keep air quality high, one room at a time. Its four-stage system consists of a pre-filter, deodorization filter, HEPA filter, and Vital Ions, all of which work together to capture up to 99.97% of airborne particles down to 0.3 microns. Those include pollen, pollutants, and other allergens. Designed for spaces up to 360 square feet, it has a colored LED for at-a-glance monitoring of air quality, multiple fan speeds with automatic shutoff, and a filter lifetime indicator.
