If the new Dyson HushJet Purifier Compact had a movie trailer, it would cut between slow-motion leaves drifting across a sunlit room and a tiny turbine nozzle gleaming like something borrowed from a private jet. It looks aerodynamic on purpose: the star-shaped top is designed to focus streams of cleaned air into fast, narrow jets that—Dyson promises—circulate and clean a room faster than a conventional desktop purifier.

The basics first: Dyson says the HushJet will land in the U.S. on September 30th with an MSRP of $349.99. It’s a genuinely small machine—about 17.7 × 9 × 9 inches and seven pounds—and it’s aimed at bedrooms, home offices and other rooms up to roughly 203 square feet. Inside is a new “electrostatic HEPA” filter that Dyson claims captures 99.97% of particles down to 0.3 microns; the company also says the filter is more energy-efficient and should last up to five years before replacement.

Dyson’s entry into the “desktop” purifier category is interesting because it gives the company license to rethink the loud, tower-like machines that dominate shelves. Instead of the familiar loop or cone designs Dyson has used for years, the HushJet uses a star-shaped nozzle that channels airflow into concentrated jets. The idea is simple: higher exit velocity moves a larger volume of room air through the unit more quickly, which should speed up whole-room purification cycles. Dyson says aerospace-style acoustics were applied to the nozzle design to reduce turbulence and keep noise down.

If that sounds like a hair-dryer with better manners, that’s not a bad shorthand. The company frames it as “fast, focused circulation” rather than brute force. The practical benefits are twofold: faster mixing of room air (so the unit can pull more contaminated air through its filters) and a smaller overall footprint for people who don’t want a tower in their workspace. WIRED and TechRadar both note this is a deliberate move away from Dyson’s big, looped purifiers toward smaller, room-specific machines.

One of the clever bits is that Dyson keeps bringing up: the nozzle is star-shaped, not just for thrust but to tame the whoosh. In “sleep” mode, the HushJet is rated at about 24dBA—Dyson likens that to soft whispers—while maximum purification reportedly remains well below levels that would disrupt conversation or concentration. If the numbers are accurate, that’s a meaningful difference: a lot of purifiers can be annoyingly loud when asked to work hard.

“Electrostatic HEPA” is Dyson’s term here: the company combines a charged filter medium with sealed housing to capture particles like pollen, pet dander and dust—those same targets most HEPA units chase. The 99.97% at 0.3 microns claim is the same figure used by HEPA standards in many contexts (it’s the DOE/industry benchmark), and reputable filtration bodies note that HEPA capture efficiency often improves for particles smaller or larger than that most-penetrating size. Still, capture rates depend on airflow, filter condition, and real-world placement. In short, it’ll remove many allergy triggers if used correctly, but no consumer purifier replaces ventilation or clinical-grade controls when those are needed.

The HushJet is equipped with sensors that monitor air quality and adjust fan speed automatically, and it supports scheduling and voice control through the MyDyson app, Alexa or Google Assistant. In other words, it behaves like most modern “connected” purifiers—automatic, set-and-forget for most owners, but with manual controls when you want them. Dyson also touts a sealed filter system, so whatever it captures stays inside the unit, which matters if you’re worried about dust leaks during filter swaps.

If you live in a small apartment or want a compact purifier that doesn’t dominate a desk, the HushJet looks like a thoughtful engineering trade-off: smaller size, jet-inspired airflow, lower claimed noise and longer filter life. For allergy sufferers or people in high-pollution areas, a full evaluation would include CADR numbers, independent noise tests, and an examination of replacement-filter costs—Dyson’s five-year filter life could be a real win if the replacement cartridge is reasonably priced. For everyone else, it’s another neat bit of product design from a company still trying to justify premium prices with engineering that feels a little like science fiction.

The HushJet arrives Sept. 30 in the U.S. at $349.99; availability in other regions and color options vary by market.
