10 Best Air Purifiers For Odor Removal 2026 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 IQAir Atem X air purifier is designed for large rooms up to 3,300 square feet, making it a strong choice if you need to cover a big space quickly—cleaning the air within about 30 minutes. Its HyperHEPA filters are especially good at capturing tiny particles like viruses, bacteria, allergens, and odors, including smoke and pet smells. This model also has smart features, letting you control it via a mobile app, which adds convenience.

The quick coverage claim indicates strong performance in air filtration. Maintenance involves replacing filters approximately every 12 to 15 months, which is fairly standard, and the company offers a long warranty if you register and keep up with filter purchases—showing confidence in durability. At nearly 29 pounds and with sizable dimensions, it’s not the most compact option, so it’s better suited for stationary use rather than moving around frequently.

The price point and smart app control position it as a premium product, ideal for those who want a high-performance purifier for odor and allergen removal in large living spaces, but it might be more than what’s needed for smaller rooms or lighter use.

The LEVOIT Core P350-P air purifier is a solid choice if you're looking to eliminate pet odors and general household smells. It uses a 3-in-1 filtration system including a HEPA filter and an activated carbon filter designed specifically to neutralize pet dander, cooking smoke, and other odors with a deodorization rate over 92%. Its AHAM verification ensures reliable air cleaning performance, which is reassuring. The purifier covers rooms up to 1050 sq ft and can refresh the air quickly in spaces around 217 sq ft in about 12.5 minutes, making it suitable for large rooms or open-plan homes.

Noise is very low at 24 decibels on sleep mode, so it won't disturb your rest or your pets. The pet lock feature is handy to prevent accidental changes from kids or animals. Filter replacements every 6-8 months are typical, and official replacement filters ensure the purifier keeps working efficiently. The unit weighs 7.5 pounds and is somewhat tall at over 14 inches, so it needs a stable spot.

While it excels in odor removal and allergen filtering, it does not use ionizers or sprays, which some might miss for extra air freshness but also means it's safer for pets and chemical-sensitive users. Although the CADR rating isn’t explicitly stated, the AHAM certification helps confirm solid cleaning ability. This makes it a user-friendly, effective air purifier especially suited for pet owners who want to reduce smells and allergens quietly and safely.
