From China, a Better Design for a Range Hood

Based on industrial air-cleaning technology

By Rain Noe - January 30

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. The company reckons this is easier than having to buy new filters (and I agree). However, none of the marketing materials show this tray, which is a little peculiar.

The company is new in the U.S., having just debuted (and drawn a lot of eyeballs) at CES earlier this month. At present there are reviews on YouTube by U.S. influencers, which I think are always suspect; it will take some time for real-world reviews to trickle in, letting us know whether this is the real deal or not.

Restaurants typically use angled metal grates which catch soot and grease that you wipe down and wash at the end of every night. It is more effort, but a better solution than having to replace a disposable filter. A residential solution using them would be a no brainer if you truly want to have less waste coming from your house.

As for the rest of the design, it feels like Dyson's "fanless" fans: same system but hides the mechanism.

When turned on, sound like an airplane is taxing in your kitchen.
