Why you should buy the Dyson Purifier Cool TP4B Purifying Fan

The Dyson Purifier Cool TP4B has two primary functions, keeping you cool and keeping your air clean. Its fan half comes from Dyson’s air multiplier technology, which is a fancy way of saying this is a bladeless fan. The power of the fan is quite great and, in combination with its 350 degree oscillation pattern, it can easily cool down a whole room. You’ll also like how safe bladeless fans are for tiny-fingered humans and pets with wagging tails.

This fan technology requires taking in a ton of air and pushing it back out. That makes it a great station for air purification as well. Your Dyson Purifier Cool TP4B will also have a fully sealed HEPA H13 filtration system, capable of removing small particles and pollutants. There’s even a real time readout that tells you about your air quality, letting you know if you have PM 2.5, PM 10, VOC, and NO2 pollutants in your air.

To save $200 and get your Dyson Purifier Cool TP4B for $350 instead of the usual $550 just tap the button below. You’ll need to be an Amazon Prime member, which you might be able to do through the free trial we discussed above. If you aren’t a Prime Member, can’t get the free trial, and don’t want to sign up or just want more options, be sure to check out these Prime Day air purifier deals that we’ve also discovered. Through it all, you’re bound to find something worthy of keeping your home’s air clean at a price you can afford.

Fraimic’s E Ink art frame generates art from your voice and looks incredible doing it
Fraimic's AI art canvas is one of the most thoughtfully designed smart frames I've come across.
Indoors, Interior Design, Person

We’ve seen a lot of "smart art frames" at CES over the years. Most of them feel like glorified digital photo frames in turtlenecks. However, there’s one that feels genuinely different: Fraimic, and I say that as someone deeply skeptical of this category.

The pitch appears quite compelling at first. Speak a prompt into the device, and its built-in mic sends the command to OpenAI's GPT Image 2.0, which then generates full-color artwork that lands on a Spectra 6 E Ink display.

Version 4.20 of the Google Home app adds a handful of pre-built routines to the Automations tab, so instead of building one from scratch, you can pick one and turn it on with a tap.

Roborock brought FIFA World Cup fever to Miami and it was blast to experience
Roborock Miami Fifa World Cup event

World Cup fever has hit Miami, and I experienced a bit of it myself at the famed Aventura Mall. Robotic vacuum manufacturer Roborock hosted a pop-up event there all weekend, allowing guests to play games, win prizes, and find out about the company’s current lineup.

The installation, dubbed “Your Home, Your Stadium,” ran in collaboration with two of Roborock’s partnerships: Real Madrid and Miami Lighthouse for the Blind and Visually Impaired. So, naturally, there was plenty of Real Madrid memorabilia on display, including a shirt signed by France striker Kylian Mbappe. Real Madrid and Brazil legend Roberto Carlos was present on the last day of the installation to greet fans.
