From China, a Better Design for a Range Hood
Ad 728×90
Chinese company Arspura developed an industrial technology to protect workers from toxic gases. It worked well, and the company then found a larger market: Domestic kitchens.
Your average range hood uses a simple fan, and relies on brute CFM to suck up cooking fumes. In contrast, Arspura's IQV (Inclined Quad-Vortex) technology uses a high-speed jet to generate four vortices and an "anti-leakage air curtain." This sucks up smoke and PM2.5 particles right above the cookware, preventing it from escaping into the room.
The demonstration—which the company claims isn't AI—is pretty dramatic: Furthermore, the units are designed with no filter. Instead grease is captured in a tray that you periodically wipe out.
