10 Best Air Purifier 2025 in the United States

The Shark Air Purifier HP153 is designed for medium to large rooms up to 650 square feet, making it a solid choice for bedrooms, home offices, or apartments. It features a HEPA-exceeding filter called NeverChange that captures 99.98% of particles down to 0.2 microns, including allergens, dust, pet dander, smoke, and odors. 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. The purifier uses 26 watts of power, which is fairly low and energy-efficient for its size. Noise levels are kept low with ultra-quiet performance and dimmable lights, ideal for sleeping or working without distraction.

It also includes a washable pre-filter (Debris Defense) that catches larger particles like hair and dust to protect the main filter and maintain performance longer. The real-time CleanSense IQ display is a helpful feature that shows you the current air quality, so you don’t have to guess if the purifier is working effectively. Controls are touch-based and straightforward. One thing to keep in mind is that while the purifier covers a large room size, it does so at one air change per hour, which is standard but may not be fast enough for very polluted environments.

This model provides strong filtration, low maintenance, and quiet operation, making it a good fit if you want reliable, long-lasting air cleaning without the hassle of frequent filter replacements.

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.

Controlling the purifier is easy and modern, with Alexa and Google Assistant compatibility plus a smartphone app for adjusting settings and monitoring air quality remotely. The device automatically adjusts fan speeds based on detected air quality, letting you set it and forget it. Maintenance is straightforward, with a pre-filter that should be vacuumed every few weeks and customizable replacement filters tailored for pets, smoke, or toxins. The filter will require regular replacement to keep performance high, which is a standard upkeep cost for HEPA purifiers. The purifier is compact and lightweight, making it easy to move between rooms.

While it is not the absolute quietest air purifier on the market, its noise level is low enough not to disturb most people during sleep. This model successfully balances strong filtration, user-friendly smart features, and energy efficiency, making it a great pick for families, allergy sufferers, or pet owners who want cleaner indoor air with minimal fuss.

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. One of its standout features is the NeverChange HEPA filter, which promises up to 5 years of usage without needing replacement, potentially saving up to $300 in filter costs over that period. This filter captures 99.98% of particles, including smoke and dust, which is slightly above standard HEPA requirements, ensuring a cleaner environment.

The unit also includes a Debris Defense filter to capture larger particles like hair and dander, which you can easily clean by vacuuming or rinsing it. Additionally, the Odor Neutralizer Technology helps to keep your home smelling fresh by reducing odors more effectively than filtration alone. A feature called Clean Sense IQ tracks air quality and automatically adjusts the purifier's power to maintain clean air, with real-time updates displayed on an LED screen.

The noise level is at 52 dB, which might be noticeable in quieter settings. It also consumes 54 watts of power, which is relatively moderate. The purifier does not require batteries and is easy to set up with no assembly required. This unit is best for users looking for minimal maintenance and extensive coverage in large living spaces.
