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

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.

The LEVOIT Core 300-P air purifier is a strong choice for removing odors, allergens, and pet hair in medium to large rooms up to about 1,095 square feet. It uses a 3-in-1 HEPA-grade filter that captures 99.97% of tiny particles including dust, pollen, smoke, and odor-causing pollutants. Its CADR of 141 cubic feet per minute means it can quickly refresh the air, making it effective in keeping your space smelling clean. The purifier operates quietly, especially in Sleep Mode, with noise dropping as low as 24 decibels, so it won’t disturb you at night. It’s powered by a 56-watt motor, which balances strong performance with reasonable energy use, and has a sleek, compact design that fits easily in most rooms.

Maintenance is straightforward but requires using genuine Levoit filters to ensure best performance and avoid potential damage, which may add to ongoing costs. The unit is designed to cycle the air once hourly in its recommended room size. Its filter options, including specialized versions for smoke or pet odors, offer flexibility depending on your needs. The Core 300-P also includes useful features like a timer, display dimming for night use, and a filter life indicator, making it user-friendly. This purifier is an excellent pick for those needing efficient odor removal combined with allergy and pet hair filtration, with the consideration that investing in official replacement filters will help maintain its optimal performance.

The LEVOIT Air Purifier LV-H128 is a compact and efficient option for small rooms. It uses a 3-stage dual-filter system which effectively removes dust, pollen, and other airborne particles, making it suitable for those with allergies or sensitivities to odors. It can handle spaces up to 161 square feet and refresh the air in just 30 minutes, making it ideal for bedrooms, offices, or kitchens.

The device is quiet, operating at a noise level as low as 28 dB, which ensures it won't disturb sleep or daily activities. It also features a Sleep Mode for even quieter operation at night. One standout feature is the fragrance sponge, which allows you to add essential oils for a pleasant aroma, adding to the air-purifying benefits.

The one-button control system makes it user-friendly and the low energy consumption (just 10 watts) is economical, costing around $10 per year to run continuously. The compact size means it's not suitable for larger rooms. Maintenance is straightforward but requires the use of official Levoit filters to ensure optimal performance, and this could be an added expense over time. For those seeking a small, quiet, and effective air purifier for personal spaces, the Levoit LV-H128 is a good choice, particularly with its added benefit of fragrance options.
