10 Best Air Purifiers For Odor Removal 2025 in the United States

The LEVOIT Core 300-P Air Purifier is a well-rounded option for those looking to remove odors and improve air quality in spaces up to 1095 square feet. It uses a HEPA-grade filter, which is highly effective in capturing 99.97% of airborne particles, including dust, pollen, and pet dander. The CADR of 141 CFM ensures that it can clean the air in a large room efficiently, making it suitable for bigger spaces or common areas in the home. The air purifier operates with a 45W high-torque motor, which contributes to its robust performance.

Using the official Levoit replacement filters is recommended to maintain this efficiency and avoid potential damage from off-brand filters. The product offers multiple filter choices tailored for different needs, like the Toxin Absorber and Smoke Remover filters, enhancing its versatility. One of its standout features is the extremely quiet operation, particularly in Sleep Mode, where it operates at a near-silent 24 dB, ensuring it won’t disrupt your sleep. The sleek and modern design, which has won a Red Dot award, allows it to blend seamlessly into any room's decor. It also features user-friendly controls, including a display light that can be turned off and a timer function.

On the downside, the need for official replacement filters might be a bit limiting and potentially more expensive over time. Additionally, while it covers a large area, the efficiency might drop if used with non-original filters. Maintenance is straightforward, with the filter replacement indicator helping to ensure timely changes. With its Energy Star, FCC, and ETL certifications, the Core 300-P is a reliable and safe choice for home use.

The LEVOIT Vital 100 is a solid choice for improving air quality in large rooms up to 788 square feet, effectively addressing odors alongside dust, pollen, and pet hair. It features a 3-stage filter system—including a washable pre-filter and activated carbon filter—that captures a wide range of particles and removes odors efficiently. With a Clean Air Delivery Rate (CADR) of 105 CFM, it refreshes the air at a steady pace, enabling multiple air changes per hour for medium to large rooms.

Operating at a low noise level of 24 decibels, it won’t disturb you during sleep or quiet moments. This model is AHAM verified, providing confidence in its tested performance and energy efficiency, consuming approximately $1.66 worth of electricity per week if run continuously. Maintenance is straightforward, with filter replacement recommended every 6 to 8 months and an indicator to remind you when it’s time. However, it requires original Levoit filters, which may be more expensive than generic alternatives. Its compact size and top air vents allow flexible placement near walls or corners.

The Vital 100 excels in odor removal and allergy relief for larger rooms, though it might be more than necessary for smaller spaces or users seeking ultra-quiet operation at very low fan speeds. This makes it a reliable, user-friendly air purifier that balances strong odor control, low noise, and easy upkeep, fitting well into most homes needing odor and allergen management.

The PuroAir HEPA Air Purifier is a solid choice for anyone needing to improve air quality in large rooms, covering an impressive 1,115 square feet. One of its standout features is the three-layer filtration system, which includes a pre-filter, HEPA filter, and activated carbon, allowing it to capture up to 99.9% of common pollutants like dust, smoke, and VOCs. This makes it particularly beneficial for allergy sufferers and those concerned about indoor air quality.

Another plus is its quiet operation, especially with the built-in sleep mode, making it suitable for bedrooms or other quiet spaces. The smart particle sensor adjusts the purifier's performance based on air quality, so you can set it up and let it work without constant monitoring. The product is also certified by reputable organizations, adding to its credibility and safety for use in homes.

However, while the PuroAir excels in many areas, it does have some limitations. Its coverage is optimal for larger areas, but using it in smaller spaces may result in overkill, potentially wasting energy. Additionally, depending on usage, regular maintenance and filter replacement could become a recurring expense, which some users might find burdensome. Lastly, the unit's size may not fit well in every room's decor, as it has a taller profile.
