10 Best Hepa Purifiers 2025 in the United States

The LEVOIT Vital 100 is a solid choice for a HEPA air purifier covering a fairly large room—up to about 788 square feet. Its AHAM verified 105 CFM CADR rating means it effectively cleans the air of dust, pollen, smoke, and pet hair with its 3-stage filtration system, which includes a washable pre-filter, a true HEPA filter, and an activated carbon filter for odors. It operates quietly, producing only 24 decibels on the lowest setting, so it’s unlikely to disturb your sleep. The compact design with top-facing vents lets you place it conveniently without needing much space. It also features user-friendly controls like a timer and a filter change indicator to help you maintain it easily.

The filters need to be replaced every 6 to 8 months, and original Levoit filters must be used, which can be somewhat costly over time. While energy efficient, consuming about $1.66 worth of electricity per week if run continuously, the purifier does not include smart features such as app control or air quality sensors available on some competitors.

The Vital 100 is well suited for anyone seeking a reliable, quiet purifier for a large bedroom, living room, or pet-friendly space, particularly if straightforward operation and effective allergen removal are priorities.

The LEVOIT LV-H132 is a solid choice for anyone looking to improve air quality in small to medium rooms, covering about 263 square feet. It uses a true HEPA filter combined with a pre-filter and activated carbon layer, which effectively traps common pollutants like dust, pollen, smoke, and odors. Certified by AHAM and other safety organizations, you can trust its performance and reliability.

One of its standout features is how quietly it runs, at just 28 dB, making it suitable for bedrooms or nurseries without disturbing sleep. The added night light with adjustable brightness is a nice touch for nighttime use, giving you some flexibility in ambiance. The unit is compact and energy-efficient, consuming only 11 watts.

This model is designed for smaller spaces and may struggle in larger rooms. While the filter replacement uses official Levoit parts to ensure performance, replacements can add to the running cost over time. This purifier suits users seeking a quiet, trustworthy solution for personal or small room use, especially for managing allergens and mild odors.

One of its standout features is the smart particle sensor which adjusts the purifier's power based on the air quality, ensuring continuous and optimal performance. It also features a quiet sleep mode, making it ideal for 24/7 use in bedrooms without disturbing your rest.
