I totally get the struggle of dealing with pet hair, especially when you have multiple cats. One of the best air purifiers I've found for pet hair and dander is the LEVOIT Core 300. It's super affordable, has a good HEPA filter that captures pet hair and dander, and works well for spaces up to around 200 sq ft

With its quiet air cleaning abilities, capturing particulate matter, odors, and volatile organic compounds (VOCs), the Airmega 450 might be my favorite air purifier from Coway to date

Coway purifiers are top notch. i have an AirMega 400 model in the room where we keep our cat litter boxes. it's built like a tank and after a year, it still showed the filters at maybe 75% remaining

Best Budget

Coway Airmega Mighty AP-1512HH

$160-$230
$160-$230 at Amazon→

You don't need to spend $500 to get real allergy relief. This Coway proves it. For bedrooms, home offices, or smaller living rooms, it's the best bang-for-buck purifier available.

What holds up

  • True HEPA filter captures 99.97% of particles down to 0.3 microns
  • Built-in air quality sensor with color-coded light indicator

What to know

  • Air quality indicator colors don't match US AQI standards (confusing color system)
  • Loudest at high setting (53 dB), so best run at lower speeds
  • Limited to smaller rooms for optimal quiet operation
  • No smart features or app control
Expert verdict
The Mighty from air purifier stalwarts Coway might have the best bang for your buck when it comes to air purifiers. At under $200, the Mighty can clean a 361-square-foot room, exchanging the air the recommended 4.8 times per hour

You could also try the Coway Airmega AP-1512HH. You'll need to replace the filters every year. If you can wait until black friday these filters usually go on sale
