The best air purifiers on Amazon for allergies, odours and more

Best for: Air cleaning performance

Quiet but mighty, the Coway Airmega air purifier is on the top on the market, removing up to 99.999% of particles including pollutants, dander, pollen, smoke and smell by using a four-stage filtration system. Its auto mode feature continually monitors and controls indoor pollution and its fan speed will adjust automatically based on the air quality.

Customers have commented on how the Airmega Mighty is easy to use, quiet and easily tackles airborne particles. “As someone who suffers with allergies and is constantly dusting my house, I have been considering buying an air purifier for years, but I’ve always been sceptical of how well they work. I did some research and learned this brand is highly rated so I thought I would take the plunge. Totally worth it. After about a month of use it is clear there is significantly less dust in my bedroom, and when the device is in auto mode it can detect when I am cooking or have opened a window to the outside,” wrote one reviewer who gave it five stars.
