10 Best Air Purifiers 2025 in the United States

The LEVOIT Vital 100 air purifier is a strong candidate for anyone needing clean air in medium to large rooms, covering about 788 square feet. Its Clean Air Delivery Rate (CADR) of 105 cubic feet per minute means it efficiently filters smoke, dust, pollen, and pet hair, making it suitable for allergy sufferers and pet owners. The 3-stage filtration system combines a washable pre-filter, an efficient fine particle filter, and an activated carbon layer, which helps remove odors and airborne particles effectively.

One of its standout features is its quiet operation; at only 24 decibels, it won’t disturb your sleep, and you can turn off the display lights for added nighttime comfort. It’s also energy efficient, costing roughly $1.66 per week to run continuously, which is budget-friendly. Filter replacement is straightforward, recommended every 6 to 8 months, with a helpful indicator to remind you when it’s time. The compact design with top air vents lets you easily place it near walls or corners without sacrificing airflow.

On the downside, this model requires using only Levoit’s original filters, which might limit options and potentially increase costs. Though the unit is well-designed for homes, it might be less ideal for very large open spaces or those requiring ultra-high CADR numbers. Also, maintenance involves regular cleaning of the outside filter surface with a brush or vacuum, but not washing the internal filters, which some users might overlook. The Vital 100 works well for bedrooms, living rooms, or offices where quiet, effective air purification is key. Its ease of use, reliable performance, and thoughtful features make it a solid choice for improving indoor air quality without complicated setup or operation.

Maintenance involves replacing the filters, and it’s recommended to use official Levoit filters for the best performance.
