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.

The PuroAir 240 HEPA Air Purifier is designed for large rooms up to 1,000 square feet, making it a solid choice for living rooms, bedrooms, or open-plan spaces. Its three-layer filtration system—including a pre-filter, HEPA filter, and activated carbon—effectively captures up to 99.9% of pollutants like dust, pollen, smoke, and even very tiny particles. This makes it particularly helpful for people with allergies or sensitivities to smoke and pet dander.

The Shark Air Purifier HP302 is designed for powerful multi-room purification with a coverage area of up to 1400 sq. ft., making it suitable for large bedrooms, living rooms, and basements.

This filter captures 99.98% of particles, including smoke and dust, which is slightly above standard HEPA requirements, ensuring a cleaner environment.
