When deciding whether or not you need an air purifier at home, you’re not off the hook just because you don’t check The Big Boxes like having intense allergies or living in a wildfire-prone area. There are pollutants and respiratory system irritants accumulating in everyone’s home simply from living there. Like the air quality index in your weather app but for inside, the new Dyson HushJet air purifier tells you exactly how much invisible gunk is floating around in the room (then captures it).

For the past few months, I’ve noticed sporadic recurring cold symptoms, like a constant runny nose and sneezing a lot. I work from home, and while I try to go for a walk every day, there are admittedly days that I don’t go outside at all — telling me that the call is coming from inside the house. Pair that with my recent plunge down a TikTok rabbit hole about microscopic mold at home, and you’ve got yourself a full-blown spiral about needing to breathe cleaner air.

The timing lined up well with the September 2025 release of Dyson’s most powerful and quietest air purifier for small spaces. That’d make any apartment-dwelling pet owner’s ears perk up, and I had to try it and validate my own concerns. After just a week with the Dyson HushJet running 24/7 in my apartment, things are a lot less stuffy around here — both my sinuses and the air in the apartment itself.

Dust and mold spores love living rent-free in your home

Indoor air isn’t clean by default just because there aren’t giant smoke stacks puffing out gray fumes right outside your window. It’s probably common knowledge that dust forms from the dead skin cells that we shed every day, as well as pollen brought in from outside, fibers from rugs or clothes, dander and fur from pets, and other yucky, random tidbits. That’s what you’re breathing in every day, and it can build up in your lungs over time, even if the effects aren’t blatant right at this moment.

Given that I review robot vacuums for a living and given how often I get roasted for my chronic daily vacuuming habits, I’m fairly certain that I vacuum far more often than most people do. I use a cordless Dyson stick vacuum with a laser that quite literally points out where the dust is, and my floors still accumulate a layer of dust over a mere 24-hour period.

Mold spores are similarly invisible and similarly inevitable. These natural fungi thrive around moisture and tend to hang out in humid spots like AC units or near the washing machine. Different people may be more or less sensitive to mold spores, but again, not great to inhale all the time.

My apartment has particularly poor airflow due to zero windows in the kitchen, poor ventilation, and absolutely useless bathroom fans. Then, the mugginess seems to make odors linger longer than they normally would. If someone makes food, the smell hangs around. If I need to empty the drawer in the automatic litter box, you can smell it the second you walk in the door — and it’s my biggest fear to be one of those cat owners whose house smells like a litter box.

The Dyson HushJet’s 360-degree Electrostatic filter and Activated Carbon filter can deal with all of these, capturing particles as small as 0.3 microns. For reference, a strand of human hair is about 70 microns wide, while the tiniest mold spores and specks of dust can be less than 1 micron.

How is the Dyson HushJet different from other air purifiers?

The Dyson HushJet strictly projects air upwards from a funky nozzle on top, rather than from around the sides like most canister air purifiers. Like the Dyson Supersonic hair dryer, the concentrated flow of air allows for higher velocity (and subsequently, faster purification). In true Dyson fashion, the HushJet has the futuristic, mechanical vibe that its stick vacuums do. If the top reminds you of an engine, you’re right — the star-shaped design mimics jet engine hush kits to produce high-powered “wind” while dulling the roar.

Air pollutants in the room are captured from every angle, though (not just through the top). While you can personally adjust the HushJet’s settings to the noise level and purification strength that you want, you can also opt for auto mode. Dyson’s Autoreact technology adjusts airflow based on the amount of pollutants sensed every few seconds.

The cylindrical filter is nearly as big as the whole machine itself, which you can reveal by pressing the two buttons on the side to lift the top part of the purifier off. It’d be really easy to change the filter in this thing, but you won’t have to worry about that for a while — the Dyson HushJet’s Electromagnetic filter is supposed to last for five years.

Does the Dyson HushJet work?

I sensed a decrease in stuffiness very soon after plugging in the HushJet. While I developed some nose blindness to the apartment’s stale air while sitting in there all day, I definitely noticed it when coming back inside after a long walk. But even 24 hours of constant HushJet usage made it feel fresher in here. Since I’ve been trying to cut back on candle usage due to some paraffin paranoia, my home simply smelling like nothing is kind of a dream. Now, a week later, every roommate in the apartment has agreed that cooking smells and cat smells aren’t loitering like they used to. The one roommate who eats meat can make bacon without the two vegetarians (who sorely miss BLTs, BTW) having to smell bacon for the next 12 hours.

But you don’t just have to base the HushJet’s performance on vibes alone. You can see the scientific proof through the live particle tracker, both in the app and on a little LCD screen on the front of the machine. The screenshots below just reflect the progress in my living room within the HushJet’s first day.

I knew I wasn’t overreacting. I KNEW OUR AIR QUALITY WAS VERY POOR.

I also appreciate that airflow adjustment can be done from my phone or with physical buttons on the purifier, depending on which gadget I’m closer to. It’s way better than having another remote lying around.

Just how hushed is the Dyson HushJet?

To fully live up to the “hush” in HushJet, I think that the purifier should be unobtrusive during daily activities, even on full power. Because otherwise, yeah, any air purifier can technically be hushed if you leave it on the lowest setting — at $349.99, you should be able to take advantage of the machine’s full purification potential without having to put up with a constant drone in the background.

Well, Dyson wasn’t fronting with this name. The Dyson HushJet is seriously very quiet. Like, I’ve had to check and make sure it didn’t come unplugged or something.

From airflow levels one through four or five, the HushJet is essentially silent. Unless I were to put my ear directly up to the machine in a totally noise-isolated room in a completely unnatural, fabricated situation, I can barely tell a difference between the noise levels of the lower half of the spectrum. If you drag the bar in the app up to levels six through 10, a very faint hum fades in. But even level 10 is notably quieter than the highest setting on the Molekule Air Mini that I’ve tried, and a world of difference between the airplane takeoff rumble of my parents’ Coway Airmega Mighty.

I set my HushJet up in the living room corner right by the couch to see how noticeable it was while watching TV or working at my desk, which is right behind the couch. I never even noticed the noise during the day unless I was specifically listening for it. As any horror fan would during October, I watched a shit ton of scary movies from the couch during my first week with the HushJet. At airflow level five, the sound didn’t drown out any dialogue or ruin any pre-jump scare ambiance.

I also brought the HushJet into my room before bed a few times. I’m a major white noise person, and leaving the HushJet on overnight felt like a much healthier alternative to turning my wall AC unit on (and probably blowing dander and dust around) just for the noise of the fan. It’s also way better than using my phone to play thunderstorm sounds all night — I really don’t want “white noise for babies” to be my top song in Spotify Wrapped again.

The HushJet’s 10 levels of airflow offer a lot of noise level customization. I’m not a parent, but air levels one through five are genuinely so soft — dare I say soothing — that I think it’d be great for a quiet nursery.

I used the Decibel X app to measure the noise level of the Dyson HushJet compared to the dishwasher murmur. When holding my phone right up beside each, the HushJet gave off 38 decibels on level three (just slightly louder than a whisper), 45 decibels on level five (equivalent to a quiet library), and 60 decibels on level 10 (equivalent to normal conversation). The dishwasher hit 57 decibels up close. If you have a robot vacuum, those HushJet numbers are way quieter than the average roar of suction power (between 65 and 70 decibels) and a self-emptying dust bin (between 70 and 75 decibels).

And remember, these numbers just reflect how loud these devices would be if your ear was less than an inch away. You’d obviously usually be a few feet away from the HushJet.

Downsides: The HushJet just works for one room at a time

The Dyson HushJet has a relatively small coverage area for the price. The HushJet’s 203 square foot max is really only purifying a single room for $349.99. The Shark NeverChange Compact Pro that we tested can cover 250 square feet for $179.99, while the popular Levoit Core 600S can cover nearly 3,000 square feet in an hour for $319.99. Granted, more high-capacity purifiers definitely don’t have the quiet aspect going for them. The Coway Airmega Mighty sounds like a plane taking off sometimes, and it’s nice that the HushJet doesn’t make you sacrifice peace and quiet.

The Dyson HushJet is also nearly as expensive as the $379.99 Blueair Comfort Pure 3-in-1 that we tested and loved. They’re similar in size, but the Blueair can also cool or heat the room.

Since the HushJet can only tackle one room at a time, many people will probably want to move it back and forth between rooms as needed, like I did. But unlike many compact floor purifiers that have handles or a strap, there’s no great way to pick the HushJet up. You just have to lift from the bottom, but at least it’s super lightweight — it only weighs about seven pounds.

Is the Dyson HushJet worth it?

I think the Dyson HushJet is worth the splurge, especially for small spaces. I genuinely noticed fresher air in my stuffy apartment within the first day, and less sneezing for no reason after a full week of use. After giving up on the Molekule Air Mini+ for being unforgivably loud on the highest setting, the Dyson HushJet’s quiet operation has been blissful. I’d recommend it to anyone looking for an air purifier for a nursery or to double as a white noise machine overnight.

Because the HushJet’s filter lasts for up to five years, it’s the first air purifier I can see myself using long-term. If you don’t trust yourself to buy new filters every six months, the Dyson HushJet is the perfect lazy person air purifier.

How we tested

The Dyson HushJet was running 24/7 in my apartment for one week at the original time of writing. It was on level 10 airflow (the highest possible) for the first 24 hours, and then was consistently between levels four and seven for the rest of the testing time. Most of the HushJet’s time was spent in my open-concept living room area, which is definitely the max for its 203 square foot coverage. I occasionally moved it to the kitchen to neutralize litter box and cooking odor and to my bedroom overnight.

These were the main factors on my mind while testing:

**Performance in terms of air quality: **To track whether the Dyson HushJet was working, I considered the overall smell and freshness in my apartment that’s prone to litter box and musty odors due to bad airflow. I also kept an eye on the particle monitor in the MyDyson app to ensure that air quality never dropped below “very good” in whatever room the HushJet was in.

Noise level: The HushJet’s name literally revolves around its noise level (or lack thereof). I wanted to ensure that it was unobtrusive to daily activities, even while running on the more powerful airflow settings. For instance, because my HushJet was right beside the couch for most of the time, I considered whether I could comfortably watch TV or have a conversation on the couch despite its hum.

User friendliness: No one’s going to want to pay for a fancy premium air purifier if it requires too much of a learning curve. I considered how easy the MyDyson app made understanding air quality metrics, and the simplicity of adjusting air flow on physical buttons and the app versus a remote. The Dyson HushJet gets automatic points in the user friendliness category because it doesn’t require recurring purchases of replacement filters.
