10 Best Air Purifiers 2026 in the United States

The Winix AM90 air purifier is a strong choice for people wanting cleaner air in medium to large rooms, as it can refresh the air in spaces up to 1,740 square feet within an hour. It uses a True HEPA filter, which is excellent at capturing tiny allergens like pollen, pet dander, dust, and smoke particles down to 0.01 microns. Alongside this, it includes a carbon filter to help reduce odors from pets, cooking, and smoke, which is handy for homes with pets or smokers. The washable pre-filter helps catch larger particles and extends the life of the main HEPA filter, making maintenance more manageable.

It operates quietly, with noise levels as low as 27 decibels on the slowest setting, so it won't disturb you during sleep or work. A smart feature worth noting is its real-time air quality monitor with LED lights and automatic fan adjustments, plus a WiFi connection that lets you control and check the purifier remotely via an app. The filter replacement indicator helps you know when it's time to change filters, which is recommended about once a year.

While the unit is rated for larger rooms, the specified floor area in some specs mentions 360 square feet, which might cause confusion; however, the AHAM verification clarifies its effective accelerated cleaning area sizes. It uses 65 watts of power, which is average for this type of device but something to consider if you want very low energy use. The Winix AM90 combines powerful filtration, smart features, and quiet operation, making it a solid option for those with allergies, pets, or concerns about household odors in medium to large living spaces.

The IQAir HealthPro Plus XE Air Purifier is designed for large rooms up to 1125 sq ft, making it ideal for spacious homes or offices. Its standout feature is the advanced HyperHEPA filtration, which effectively removes 99.995% of airborne particles as small as 0.003 microns, providing significant protection against smoke, allergens, mold, and odors. This makes it particularly beneficial for individuals with asthma or allergies. The purifier is Swiss-made, which speaks to its quality and durability, and comes with a 10-year warranty when specific conditions are met, reflecting the brand's confidence in the product's longevity.

The noise level is relatively low at 35 dB, ensuring a quiet operation that won't disrupt daily activities. Its energy-efficient design, featuring a redesigned fan system, helps reduce power consumption, which is advantageous for environmentally conscious users. Incorporating smart technology, it connects with IQAir’s AirVisual app, allowing remote monitoring and control, and automatically adjusts its operation based on air quality readings to prolong filter life.

However, the initial cost and potential ongoing expenses for filter replacements could be a drawback for some users, especially given that maintaining the extended warranty requires subscription to a filter program or purchasing filters regularly. Its weight and size may also be less convenient for users who need to move it frequently. Despite its best sellers rank, users should consider these factors alongside its proven efficiency and smart features when deciding if it's the right air purifier for their needs.

The washable fine mesh pre-filter helps catch larger particles and extends the HEPA filter's life, reducing how often you’ll need replacements. Its advanced carbon filter targets odors and harmful gases from pets, cooking, and smoke, enhancing the freshness of your indoor air. The PlasmaWave technology offers an additional layer of air cleaning without producing harmful ozone. Noise levels are quite low at 27 dB, so it can run quietly in the background without disturbing daily activities or sleep. At 50 watts, its energy consumption is moderate compared to similar models, which is reasonable for a purifier covering large areas.

The smart sensors and auto mode adjust fan speed based on air quality, ensuring efficient operation without manual settings. You can also control and monitor the unit remotely via the Winix Smart App with WiFi, adding convenience. Maintenance is straightforward with filter replacement indicators and no assembly required. While the purifier is slightly heavier and larger than some compact models, this is common for units with such strong performance.
