This is the time of year when I think about finding the right air purifier. In this year’s tests, we’ve reaffirmed that the [Coway AP-1512HH Mighty]( is the best for most people, thanks to its good performance and economical running costs. We also finally tested the Molekule air purifier, which everyone gets social media ads for, and we found in our tests that it “turned in the worst performance on particulates of any purifier, of any size, of any price, that we have tested in the seven years that we have been producing this guide.” We found that on its auto setting, which is its medium setting, the Molekule reduced 0.3-micron particulates by (in the best case) only 26.4 percent over the course of half an hour. Compare that with the 87.6 percent reduction the Coway Mighty achieved on its medium setting. [Check out our results]( and let us know what your experience with the Molekule has been. Here’s the latest on new, upcoming, and updated guides: - Did you get a new iPhone 11? Our case recommendations are going to be the [Smartish Kung Fu Grip]( for most, the [Apple Leather Case]( for leather lovers, and the [Smartish Wallet Slayer Vol. 1]( for those seeking a wallet case. If you need extra protection (from, say, a kid who loves to chuck your phone across the room, or if you have butterfingers), [Speck’s Presidio Pro]( has extra air pockets for damage control. And if you want a folio case (think a book cover with card slots), go for [Speck’s Presidio Folio](. [Spigen’s Liquid Crystal]( is the best of the clear cases, and the [Caudabe Veil]( is the best of the ultrathin covers. Protect your investment! - We also have a new [dash cam]( pick: the [Nextbase 522GW](. It produced the sharpest video we’ve seen, and it can automatically notify emergency services for you after a crash. It also has a powered magnetic mount, which means there’s less fiddling when you hide the camera or move it from car to car. - Printers are a tricky category because there are a lot of lemons out there, but after new testing, we have a new high-end upgrade pick in our [printers guide]( the [HP Color LaserJet Pro MFP M479fdw](. ‌ [New this week at the Wirecutter] ‌ Our newest and recently updated reviews ‌ ‌ CARS ‌ [The Best Dash Cam]( ‌ Our pick: [Nextbase 522GW]( ‌ Updated September 30 ‌ ‌ BLOG ‌ [Don’t Buy an Electric Scooter]( ‌ After researching dozens of electric scooters and riding five, for a total of 100 miles, we’ve concluded that you shouldn’t buy one.
