Dyson's HushJet Compact Purifier is a quiet powerhouse — although it's not so mini as others

If, like me, you suffer from seasonal or dust allergies, I've found having one of the best air purifiers in my home to be a real life-saver. And when it comes to air purification and tech, Dyson has always been ahead of the game. Not just for its advanced filtration and exceptional power but for its iconic bladeless designs.

Which is why the HushJet Compact Air Purifier is a breath of fresh air (no pun intended). With its jet engine nozzle design, it boasts more power whilst claiming to be whisper-quiet, and its small footprint makes it more convenient for compact rooms, without looking like an eyesore.

But with its hefty price tag, is it really worth the hype? I put the HushJet Compact Air Purifier to work in my home for a month to find out. I tested its ease of use and how quickly it got rid of smoke, scent, and lingering cooking odors. Here's the lowdown.

Dyson HushJet Purifier Compact: The ups

While testing the Dyson HushJet Compact purifier, here are some of the key things that I loved about it.

Smaller and sleek upgraded design

Unboxing the Dyson HushJet Compact purifier was a simple task, thanks to its smaller, lightweight profile. In addition, putting it together was a breeze; you just secure the top 'jet-engine' piece on top of the body with a click.

Perhaps the most interesting thing is its upgraded, stylish design. Unlike its predecessors, the HushJet has a nozzle at the top that's inspired by jet engine (promising a more quieter operation), and a sleek, cylindrical body. In fact, the HushJet resembles more of a speaker than an air purifier, and certainly won't look out of place in any room.

It's also the smallest air purifier in the line-up (so far), with a footprint of 23 -49 cm (19 in height), which is ideal to fit in a compact room.

It's also simple to operate with just three buttons (fan speed, power, and info), and an LCD screen on the body. You can either use it manually or connect via the app, via Bluetooth, or Wi-Fi, which gives you more options at a glance.

Perhaps the only downside is that it doesn't have a cooling fan or heat function, which other Dyson air purifiers offer. However, if your sole purpose is having clean air on a regular basis, this isn't a major deal breaker.

I'm still undecided whether I prefer the iconic, bladeless Dyson design, but the HushJet's, sleek, low-profile upgrade does well to blend with any modern interior.

Quick responses to air quality changes

I decided to first put the HushJet to the test in my medium-sized living room to see how well it removed odors. Since I frequently burn scented candles and incense, this was the ideal first challenge.

Set to Auto, it didn’t take long before the power ramped up within seconds after I lit an incense stick. I was impressed by the fast response to the change in indoor air quality, where the color on the LCD screen quickly went from green (good) to red (very poor).

The readings also indicated high levels of particulate matter: a PM2.5 reading of 69g/m3 and a PM10 reading of 71g/m3, which is often linked to the removal of larger microscopic particles.

And while you wouldn't ordinarily hold a lit incense stick up close to your purifier, I was pleased to see that the color readings had returned to a green after cleaning the air in under 40 minutes — which is impressive considering how strong the aroma was. What's more, I could tell the difference in the overall air quality when I walked back into the room an hour later, which was literally refreshing.

I also replicated the same test by squirting some perfume in the air. To my surprise, it managed to filter the air in just five minutes, going from a poor (orange) quality to good. Of course, you have 10 fan speed settings to choose from, but I tend to stick to Auto as I find it to be more effective when detecting pollutants in the room, and also more eco-friendly, cutting down on energy consumption.

Since I have a somewhat open-plan living area, there's nothing I hate more than cooking smells drifting in from the kitchen. After placing it on the floor nearby my stove, it took slightly longer to remove any lingering odors. In fact, looking at my timer, it had taken precisely 52.29 minutes to completely clean the air. Compared to removing scents, this process took longer, but was still completed in under an hour, which still outperforms other air purifiers I've tested.

It's worth noting that considering both my living room and kitchen area are medium-sized , the HushJet may not be as effective in larger spaces. But, since the HushJet is designed for smaller spaces, I was very impressed at how powerful and effective it was at getting the job done well.

It really is super quiet

The HushJet isn't called 'whisper quiet' for no reason, and I was particularly impressed by how quiet it remained, especially when set to Sleep mode. According to my sound meter, it recorded a steady 27dB on Auto mode, and ramped up to 60dB at the highest dan speed of 10, which is equivalent to a conversation.

In Sleep mode however , it registered as 24dB. This reading is slightly louder than a whisper, which is typically classified as 20dB, but was significantly quieter. In fact, I didn't even notice it was on while I was sleeping, and I appreciate that the LCD light automatically switches off when set to that mode.

This makes it ideal for placing in a bedroom, nursery, or simply when you just want to relax in peace, without the usual interruptions of an air purifier.

It has a user-friendly app

Since I already have Dyson appliances pairing the HushJet purifier through the MyDyson app was simple. However, first-timers will need to download the app that allows one-touch control through its intuitive interface. In addition, if you have a smart home set-up, you can connect by using compatible voice services such as Amazon Alexa, Google Assistant, or Siri.

Besides being able to control your settings, fan, and Sleep mode, I like how the app gives you real-time insights about how good or bad your indoor air quality is, and even lets me know what the outdoor quality is like (so I can close my windows if need be). You can also customize a schedule, so you can set specific times when you want your air purifier on and off in advance.

Admittedly, I'm not a big app person, but I found it to come in handy, especially when monitoring my air quality at a glance.

Dyson HushJet Purifier Compact: The downs

While it's clear that the Dyson HushJet purifier had some great wins, there were downsides (albeit minor ones).

It's not as 'compact' as it claims

Interestingly, the HushJet air purifier claims to be compact enough to fit on a desk or tabletop, but I found this not to be case (unless you have a massive desk!). I thought its size was still too big and looked clunky on my table, despite having the word 'compact' in its name.

But, it is still smaller in comparison to other powerhouses, and if you have limited floor space, light enough to elevate. If you do want a mini air purifier however, I'd probably opt for the Shark NeverChange air purifier, which can fit snugly into a corner or on a small table.

Dyson HushJet Purifier Compact: Verdict

In a nutshell, the Dyson HushJet is a powerful, lightweight, and eye-catching purifier that works well to quickly pull in airborne particles and pollution. I was most impressed at how quickly it detects air quality changes and reacts accordingly, (especially to my extremely potent incense stick). Its filter also has a five-year lifespan, which is always a bonus. Best of all, it's super quiet — you might not notice when it's on.

While it performed well within my small to medium-sized spaces, this probably wouldn't be as effective in larger spaces. In which case, you should opt for the Blueair Signature air purifier, which came tops in our guide for the best overall.

Also, bear in mind that this doesn't include a cooling function, which you can get in other models. And considering its premium price tag, I would expect to get more versatility to make this a worthwhile investment. Still, if you do want a dual air purifier/fan, you can opt for the Dyson Purifier HP07, which also heats.

Overall, the Dyson HushJet air purifier is highly effective, particularly in smaller rooms or households. So if you need a compact, efficient air purifier, the HushJet is an excellent choice that will easily meet, and likely exceed, expectations.
