The Core 300-P is Levoit's mid-range air purifier that cleared test rooms of wildfire smoke and pollen in about 46 minutes—impressive performance for the price.
It uses three-stage filtration (pre-filter, HEPA, activated carbon) to capture 99.97% of particles 0.3 microns or larger, making it effective against dust, pet dander, smoke, and allergens. Premium features include a filter health monitor, adjustable sleep timer (2/4/6/8 hours), and an interface light for operating in the dark.
At 7.6 pounds with handles, it's easy to move between rooms and covers up to 219 square feet effectively.
