Dyson air purifiers are a great deal.

Today only, Best Buy is offering the Dyson Pure Hot + Cool air purifier for $549. That's $100 off the original price of $649 and one of the best Dyson deals we've seen this year. With Best Buy's expedited shipping service, you can get a brand new Dyson in as little as two days.

Sophisticated, high-end design is Dyson's forte, and the Pure Hot + Cool air purifier is no exception. The smart device has a metallic finish and is shaped like a paper clip; the top of the Pure Hot + Cool draws in and purifies air throughout the house, while also acting as a fan and heater. It is also safe for pets and children.

This multifunctional device purifies a room up to 800 square feet with a HEPA air filter, a carbon filter, and a smart sensor that displays air quality on an LCD display.

Now, when it comes to the canister at the bottom of the device, this is where the magic happens. Air is sucked in and nearly 99% of allergens are removed. According to Dyson, the Pure Hot + Cool air purifier is certified asthma and allergy friendly and is Quiet Mark certified.
