Best Overall

Coway Airmega AP-1512HH Mighty

$100-$150

This is the air purifier I'd tell any allergy sufferer to buy first, it's the consensus pick across both expert labs and real owners, and it's hard to beat at this price.

  • Quiet operation makes it suitable for bedroom use overnight
  • Covers far larger spaces than similarly priced competitors
  • Energy-efficient, draws less power than rivals with smaller coverage
  • True HEPA filter captures dust, pollen, and fine particles

What to know

  • Design is utilitarian and not aesthetically exciting
  • Filter replacement costs add up over time
  • No built-in app or smart home integration on base model
What people say
Our Winix units really helped with my allergies, but in reality any HEPA filter will help, especially if you place them around the house in different rooms.
