Best for Large Rooms

Whether you’re dealing with an open-concept space or a particularly large room, the Orsani Mod+ Hepa Air Filter delivers exceptional performance. It can purify up to 2,722 square feet per hour and 1,361 square feet every 30 minutes, ensuring comprehensive coverage. Its three-in-one filtration system effectively captures pet dander, pollen, dust, and activated carbon, making it a versatile choice.

Setting up the unit was incredibly straightforward, and the interface was equally intuitive. Instead of preset modes, you adjust the intensity by sliding your finger along a half-circle arc from low to high.

We observed a minor delay in the touchscreen response, which, while slightly annoying, wasn’t a major issue. The touchscreen briefly illuminates upon interaction, keeping it unobtrusive, and the noise level is low and calming. The combination of gentle sounds and a dim display makes this purifier an excellent choice for nighttime use.

Overall, this air purifier’s performance left us thoroughly impressed. It kept our apartment feeling fresh—even on smog-heavy days—and effectively neutralized the strong odor from our cat’s litter box during warmer months. After six months of use, it continues to surpass our expectations.

Given its powerful performance, it’s no surprise that this unit is quite large, which might not suit smaller spaces. However, its minimalist design allows it to blend seamlessly into any decor, and the built-in handle makes it easy to move between rooms.

Final Verdict

Our top choice is the Winix 5500-2 Air Purifier, which outperformed others in filtering pet hair, odors, and fine particles like pet dander. It can also purify up to 1,740 square feet in an hour, making it ideal for larger spaces.

Our Testing Process

We rigorously tested 61 air purifiers in both lab and home environments, assessing them on design, noise levels, performance, and value. First, we timed the assembly process for each unit, noting the clarity of the instructions. We then evaluated the design based on build quality, aesthetics, features, and size. 

Next, we used a decibel meter to measure noise levels at both the highest and lowest settings. For models with extra features like air quality indicators or Wi-Fi connectivity, we tested these functions and noted their usability and ease of operation. 

We also tested each purifier’s effectiveness in cleaning the air. To do this, we set up monitoring stations throughout the testing area and recorded baseline PM2.5 (particles 2.5 microns or smaller) and volatile organic compound (VOC) levels at each station. 

We released various contaminants at each station, such as mothballs, incense smoke, pet hair, scented room spray, and a blend of dust, dirt, and flour. We then measured PM2.5 and VOC levels again at each station and from different distances. After running each purifier on its lowest setting for 30 minutes, we recorded PM2.5 and VOC levels once more. We repeated this process with the purifier on its highest setting.

Finally, we evaluated the overall value of each air purifier based on its price and performance. We factored in the cost of replacement filters and calculated the estimated annual energy cost by averaging wattage on the highest and lowest settings, using the U.S. average of $0.16 per kilowatt-hour—assuming 24/7 operation year-round. 

After completing lab tests, we took the top-performing air purifiers home and monitored their performance over one, three, and six months of use.

More to Consider

Levoit EverestAir Smart Air Purifier: This model’s intuitive app lets you control airflow direction, and its AirSight Plus technology automatically activates when air quality drops. However, we wish there was a way to adjust the display directly on the unit.

LG PuriCare AeroTower Air Purifying Fan: Featuring 10 fan speeds and a turbo mode, this purifier impressed us with its ability to enhance air quality and eliminate odors. That said, it struggled in larger, open areas. 

How to Shop for Air Purifiers for Pets Like a Pro

Filter Type

Different filter types are engineered to capture specific pollutants, and most pet-friendly air purifiers combine two or more filters to tackle pet hair, allergens, and odors. Some filters are washable, while others require annual or semi-annual replacement, so it’s crucial to consider replacement costs when choosing a purifier. Here’s a quick guide to the filters you might encounter when shopping for a pet air purifier: 

HEPA Filters: HEPA, or high-efficiency particulate air, filters are the most effective at capturing airborne particles, including pet dander. These mechanical filters push air through a fine mesh, trapping even microscopic particles. "For pet owners, an air purifier with a HEPA filter is ideal, as it removes 99.97% of allergens and pollutants as small as 0.3 microns," says Mendez. Typically, HEPA filters should be replaced, not cleaned, every six to 12 months, but always follow the manufacturer’s recommendations.

Activated Carbon Filters: For pet odors, activated carbon (or charcoal) filters are essential. They absorb contaminants like VOCs that HEPA filters can’t capture. Often paired with HEPA filters, they tackle both allergens and odors. Generally, activated carbon filters should be replaced every three to six months.

Pre-Filters: Many purifiers include pre-filters to catch large debris and dirt. They’re especially useful for heavy shedders, as they trap hair before it reaches the HEPA filter. To maintain effectiveness, pre-filters should be cleaned regularly and dried completely—any residual moisture can lead to mold.

Strength

An air purifier’s effectiveness is measured by its Clean Air Delivery Rate (CADR), which shows how much purified air it generates at maximum speed. Some manufacturers provide a single CADR rating, while others categorize it into pollen, dust, and smoke. 

When selecting the right air purifier, consider the size and layout of your space. A smaller purifier may struggle in larger rooms, while an oversized model could consume unnecessary energy. 

For apartments or smaller spaces, consider the Kenmore 850e Air Purifier with SilentClean HEPA Technology - PM1005, which covers up to 850 square feet. For larger homes or open layouts, the Orsani Mod+ HEPA Filter is a great choice, capable of purifying up to 2,722 square feet.

Noise Level

Noise is a key factor, particularly for households with sensitive pets. Higher settings tend to be louder, but some models are quieter than others. The air purifiers we tested ranged from 20 to 60 decibels in noise levels. 

If you intend to run the purifier in a bedroom or living area continuously, opt for a quiet model. While some purifiers auto-adjust based on air quality, choose one with manual mode options for customizable speed settings. 

Some models even feature a dedicated quiet mode for nighttime use. In our tests, the Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier w/WiFi excelled with its near-silent operation, especially in silent mode.

Certifications

To save on utility costs, consider an Energy Star-certified air purifier. This certification guarantees the unit meets energy-efficiency standards set by the Environmental Protection Agency. For allergy sufferers, the Asthma & Allergy Friendly Certification Program (managed by the Asthma and Allergy Foundation of America and Allergy Standards Limited) independently tests purifiers to ensure they reduce airborne allergens effectively.

Additionally, the Association of Home Appliance Manufacturers (AHAM) Verifide label confirms the product has been independently tested for CADR and room size claims. Also, look for Intertek’s Electrical Testing Laboratories (ETL) Listed mark, indicating compliance with North American safety standards, or the Underwriters Laboratory (UL) Listed mark, which signifies adherence to its safety standards. (ETL does not create its own safety standards.)

Questions You Might Ask

How often does an air purifier filter need to be replaced?

To maintain optimal performance and prevent allergens from re-entering the air, Mendez emphasizes the need to regularly clean or replace your filters. Washable filters should be rinsed or wiped monthly, while non-washable ones can be gently vacuumed. Disposable filters typically need replacement every six to 12 months, as specified by the manufacturer. 

For a low-maintenance option, the Shark NeverChange Air Purifier MAX features filters that last up to five years, making it a convenient choice.

What filters are best for pet hair and odors?

All recommended air purifiers include multi-stage filtration systems, usually with three to six levels. Pre-filters are crucial for capturing larger debris like pet hair, while HEPA filters excel at trapping smaller particles such as pet dander. 

For odor control, prioritize purifiers with activated carbon (or charcoal) filters, which absorb pet odors and other gases. Four of our top five picks include an activated carbon filter—while the Shark NeverChange Air Purifier MAX lacks one, it uses advanced odor-neutralizing technology that leaves a pleasant scent.
