10 Best Air Purifier For Cats 2025 in the United States

The Levoit Core P350-P air purifier is designed specifically with pet owners in mind, effectively tackling the common challenges that come with keeping a clean and fresh home when you have furry friends. Its 3-in-1 filtration system combines a HEPA filter and activated carbon filter, which can capture pet dander, odors, dust, and even small particles as tiny as 0.3 microns. This capability helps reduce allergens in the air, making it a great choice for those who suffer from allergies or respiratory issues related to pets.

One standout feature is its impressive odor removal capability, achieving a deodorization rate of over 92%. This is particularly beneficial for pet owners who may deal with litter box smells or general pet odors in the home. The air purifier is also quite efficient, able to clean a room of approximately 219 square feet in just 12 minutes, which means you can enjoy cleaner air quickly.

Noise level is another area where the Core P350-P shines. With a sleep mode that keeps the noise as low as 24 dB, it ensures that both pets and their owners can rest peacefully without disturbance. The unit also includes a Pet Lock feature, preventing pets or children from changing the settings, which adds an extra layer of convenience for families. The unit requires filter replacements every 6 to 8 months, which could be a consideration for some users. It is rated for larger rooms (up to 1,092 square feet), but its optimal performance is in smaller spaces. The design may also be a bit bulky for smaller apartments.

The Levoit Core P350-P air purifier is a strong option for cat owners and pet parents, providing effective air purification, low noise levels, and features tailored to households with pets.

The PuroAir HEPA Air Purifier is an efficient option for those looking to maintain clean air in larger rooms, covering up to 1,115 square feet. With a three-layer filtration system including a pre-filter, HEPA filter, and activated carbon filter, it effectively captures 99.9% of pollutants such as dust, pollen, smoke, pet dander, and VOCs. This makes it particularly suitable for homes with cats, where pet dander can be a concern.

The air purifier is backed by scientific testing and certifications from CARB, ETL, ISO, UL, and Energy Star, ensuring reliability and performance. Additionally, it features a smart particle sensor that adjusts the power based on air quality, allowing for continuous and efficient operation with minimal noise—ideal for use in bedrooms and around the clock. The sleep mode further ensures quiet operation, promoting better sleep quality.

However, at 16 pounds and with dimensions of 10.63 x 10.63 x 16.14 inches, it may be a bit bulky for some users. Maintenance involves regular filter replacements, which could add to the long-term cost. Despite these minor drawbacks, the PuroAir HEPA Air Purifier offers strong performance and peace of mind with a 2-year risk-free warranty and responsive customer support, making it a solid choice for pet owners seeking cleaner air.

The Shark NeverChange Compact Pro is a solid option for anyone looking to reduce pet dander, dust, and odors in rooms up to 250 square feet—ideal for bedrooms, nurseries, or home offices. Its HEPA-exceeding filter captures 99.98% of airborne particles, including very small allergens, which is great for cat owners concerned about air quality. Added features like the washable pre-filter help trap larger debris like pet hair, which protects the main filter and extends its life, reducing the frequency of filter replacements and potentially saving money over time.

The activated carbon odor neutralizer also helps keep unwanted smells in check, releasing a light scent that freshens the air without being overpowering. It operates quietly with dimmable lights, so it won’t disturb sleep, making it a good fit for bedrooms and nurseries. The air quality display and simple controls allow users to easily monitor performance and adjust settings.

Its coverage is best suited for smaller spaces (up to 250 sq. ft.), so larger rooms might require multiple units or a different model. While filter replacement costs are lower than many competitors, the purifier does require assembly out of the box. This Shark purifier strikes a good balance of efficient particle removal, odor control, and ease of use, making it a practical choice for cat owners wanting cleaner air in small to medium rooms.
