Today, the Dyson Purifier Cool TP07 is available at an all-time low on Amazon Prime Day: The discounted price brings the price down to $349, a staggering 46% discount from the regular $649. This is a small window of time to invest in cleaner air for your home for a price that’s hard to beat.

I spotted Dyson’s best-selling air purifier with a very good Amazon Prime Day deal this morning and immediately alerted my group chats. The best-selling model, the TP07, has a HEPA filter, automatic sensors that trap pollutants and 350-degree oscillation and is an overall great investment for anyone looking to improve their home’s air quality.

Rare Prime Day deals ahead on Dyson bestsellers, including the Airwrap, noise-canceling headphones, powerful cordless vacuums, and air purifiers.
