Breathe easy — Save up to 40% off these top brand air purifiers for Prime Day, from Blueair, Levoit and Shark

The Blue Signature air purifier was a clear winner in our tests, due to efficiency and quickly works well in large spaces. This model provides a high CADR in terms of dust, smoke and pollen, and offers plenty of handy settings, and WiFi-enabled. Plus, the design even doubles up as a coffee table!

The Shark NeverChange may look small and compact, but it’s mighty. And during our review, it rated highly in filtering the air, and capable of tackling a large room. In addition, it comes with an anti-allergen HEPA filter designed to handle a wide range of air contaminants, and has an odor-neutralizer to keep air free from lingering smells. Perhaps the main USP of this model is its NeverChange filter, which will last up to five years – saving you a fortune in the long-run.

If you want to treat yourself to an all-in-one appliance, the Dyson Purifier HP07 Air Purifier is a great investment. Not only does it clean the air, but offers a powerful heating and cooling fan. It also comes with App control and real-time reports. If you want a high-spec purifier, and unique style, this is a good buy.

If you’re on a budget, this Clorox purifier came tops in our guide for affordability. Simple to set up, it features a touchscreen that lets you control all of its functions, and it has clear indicators for fan settings. It's worth noting that the discount is only on the medium sized purifier ( ideal for rooms up to 1,000 sq ft.), however, it’s still great value for money considering how quick it cleans the air. A great deal while it lasts.

If you’re after a small yet powerful purifier that can handle mid-large spaces, this Levoit Core smart model is ideal. It comes with a three-stage filtration, and has an auto feature that scans the air for particles and adjusts the fan speed accordingly. Plus, it sends back real-time reports to your phone, for added convenience.
