Looking for cleaner, fresher air at home? The Blueair Blue Signature air purifier is our top pick. It looks the part, it is powerful and it's highly effective at removing dust, pollen, smoke, and odors, making it a great choice for allergy sufferers or anyone wanting to improve indoor air quality. It's now even cheaper with this early Black Friday deal. It's especially good for animal lovers (which is why we have featured it in our best air purifiers for pet owners guide) as it eliminates the smells of 'wet dog', unwanted litter tray odors and well-worn pet bedding.

You can get the Blueair Blue Signature for $299.99 at Amazon now.

We would have scored this unit the full five stars, had it not been for the premium price tag, but with this Black Friday deal, it's definitely worth shouting about. Grab a premium, good-looking air purifier at a great price. We'd hesitate to say 'jump in' at the RRP of $499.99, but at less than $300, we think it's worth it!
