If you're considering buying the Dyson V11 at Amazon for $399.99 this Prime Day, don't. Spend $50 more and snag the actual best Dyson deal this Prime Day: The Dyson V12 Detect Slim for $449.99 at Walmart's conveniently-timed summer sale.

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.

This Prime Day deal is exclusive to Prime members, so you’ll need a subscription to take advantage of this record-low price: The Dyson V8 Plus is now available for just $299, which is a massive 36% off its usual $469 price tag. At this price, it’s hard to justify spending two or three times more for only minor improvements found in newer models.
