8 Best Air Purifiers Tested in Homes with Cats: Which Ones Really Work?

“Scrub pet odors and dander from your air for a fresher, cleaner home.”

Breathe Easier at Home: Best Air Purifiers for Pet Owners

Living with pets often means dealing with dander, hair, and other allergens that can irritate your sinuses and eyes. An effective air purifier can significantly reduce these airborne particles, improving indoor air quality and providing relief for allergy sufferers.

According to Melanie Carver, Chief Mission Officer of the Asthma and Allergy Foundation of America, HEPA filters are certified to remove particles as small as 0.3 microns—including pet dander, mold, dust, and bacteria—when properly maintained. This makes HEPA-equipped purifiers a top choice for homes with pets.

To help pet parents find the right solution, we tested 47 air purifiers in both controlled labs and real homes, evaluating performance, noise levels, and ease of use.

Other Options

  • Hamilton Beach TrueAir Air Purifier
    Once our top budget pick based on home testing, the Hamilton Beach TrueAir ultimately didn’t measure up in our controlled lab environment. While we appreciated its ultra-quiet performance—clocking in at just 48.1 decibels on whisper mode—its filtration power was lacking. In our PM 2.5 test, it only reduced levels to 275.7 after five minutes in a sealed greenhouse, leaving room for improvement compared to other purifiers at a similar price point.
  • Pure Enrichment PureZone Air Purifier
    Previously selected as our best portable pick, the PureZone stands out for its lightweight design and convenient handle. However, it underperformed in our lab tests. After five minutes on its lowest setting, PM 2.5 levels only dropped from 999.9 to 829.2—making it one of the least effective models we tested for reducing fine particulate matter.

What to Look for in an Air Purifier

Choosing an air purifier for your home—especially with pets—means balancing scientifically proven features with helpful (and sometimes unnecessary) tech enhancements. Some models offer app control, voice commands, or remote operation, while others keep things simple. The following guide breaks down the most essential features and terms so you can make the most informed decision.


Key Terminology

  • HEPA (High-Efficiency Particulate Air):
    Certified HEPA filters remove at least 99.97% of airborne particles as small as 0.3 microns—including dust, pollen, mold, and pet dander. According to the EPA, this is the gold standard for air filtration in residential spaces.
  • CADR (Clean Air Delivery Rate):
    This score measures how quickly an air purifier can filter dust, pollen, and smoke. A higher CADR equals faster, more efficient air cleaning. A general rule: choose a unit with a CADR that’s at least two-thirds the square footage of your room (e.g., a 100 sq ft room should have a minimum CADR of 67).
  • Activated Carbon Filter:
    These filters neutralize odors and gases, including smoke and volatile organic compounds (VOCs). Since they don’t capture fine particles like pollen or mold, they’re most effective when paired with a HEPA filter.
  • Pre-Filter:
    The first line of defense, this filter captures large particles like pet hair and dust. While helpful, pre-filters aren’t meant to replace a vacuum cleaner’s role in hair removal.
  • UV Light:
    Found in select models (like the Bionaire 360 UV), UV lights help kill airborne bacteria and germs inside the purifier’s chamber. They’re often combined with HEPA and carbon filters for maximum effectiveness.

Strength and Room Size

Power and room compatibility vary widely. Most air purifiers specify a recommended coverage area (in square or cubic feet), which is essential for matching the device to your needs.

If you have multiple pets or household members with allergies, consider models with higher CADR ratings and multi-stage filtration.


Design, Features, and Noise

  • Design & Placement:
    Choose a model that complements your space, especially if it will live in a visible area like the living room or bedroom. Many models come in different colors or finishes.
  • Smart Features:
    App control, voice commands, and auto sensors are great for convenience. Some also feature night modes that dim display lights or reduce fan speeds.
  • Noise Levels:
    Some purifiers generate soothing white noise, while others are nearly silent. Many models allow you to adjust the sound output, or switch to a quieter setting at night.

Frequently Asked Questions

How do air purifiers work?

Air purifiers typically use one or more of the following technologies:

  • HEPA Filters: Trap tiny airborne particles like pet dander, dust, and pollen.
  • Activated Carbon Filters: Absorb gases and neutralize odors.
  • UV Light: Kills airborne bacteria and viruses inside the purifier.

Do air purifiers reduce pet dander?

Yes. HEPA filters are especially effective at trapping pet dander, which ranges from 5 to 10 microns in size. HEPA filters can trap particles as small as 0.3 microns.


Do air purifiers remove pet hair?

To some extent. Air purifiers with pre-filters or HEPA filters can trap floating pet hair, but hair embedded in carpets, clothing, or upholstery will still need vacuuming.


Where is the best place to keep an air purifier?

Place your air purifier close to the pollutant source for best results—like near your pet’s bed, litter box, or a frequently used couch. Ensure there’s enough space around it for unobstructed airflow.


How do you maintain an air purifier?

Follow the manufacturer’s cleaning and filter replacement schedule:

  • Reusable filters can often be rinsed or vacuumed.
  • Replaceable filters should typically be swapped every 3 to 6 months.
  • Some units have indicator lights that alert you when it’s time to clean or replace a filter.

Do I need a HEPA filter?

Not necessarily. Some manufacturers use proprietary filtration technologies. However, HEPA filters remain the industry standard, especially if you’re targeting allergens like pet dander or pollen. For a filter to be HEPA certified, it must meet the U.S. Department of Energy standards and remove 99.97% of 0.3-micron particles.
