10 Best Air Purifier 2025 in the United States

The LEVOIT Core 300S-P air purifier is a strong choice for anyone looking to clean the air in bedrooms or larger rooms up to about 1060 square feet. It uses a 3-stage HEPA filtration system that effectively captures tiny particles as small as 0.1 micrometers, which helps reduce dust, pet hair, allergens, smoke, and odors. Its AHAM certification guarantees reliable air cleaning performance. One of its best features is how quiet it runs—only 22 decibels in sleep mode—making it ideal for light sleepers. It also saves energy with a low-power DC motor, so it can run continuously without high electricity costs.

This filter technology is impressive because it lasts years without needing replacement, which can save you money compared to other brands that require frequent filter changes.
