Blueair Blue Signature: two-minute review
The Blueair Blue Signature is a furniture-inspired air purifier for extra-large rooms, available from Blueair, Amazon, and different third-party retailers.
You should buy the Blueair Blue Signature for an inventory worth of $449.99 / £369, nevertheless it’s value protecting an eye fixed out for reductions to maximise the worth. I’ve not noticed any within the UK to this point, however on the time of writing, US prospects can get a $50 low cost at Blueair, bringing the worth all the way down to an much more cheap $399.99.
Whereas the mid-gray Gentle mannequin is extra to my desire, the navy blue Darkish mannequin I’ve been testing does a terrific job of mixing into the room, fairly than standing out like different white plastic air purifiers usually do.
Like many of Blueair’s purifiers, the Blue Signature features an easy-to-clean fabric pre-filter, which is available in a range of colors to help it blend in with your decor.
At 15.5 inches / 39.4cm in diameter, there’s plenty of room to plonk down the remote or a magazine, but as I learned from my experience, you’ll need to be mindful about placing anything that could scratch the tabletop.
The Blue Signature is satisfyingly lightweight considering its size, making it easy to unbox and set up. I found it to be a little low for my liking, but this may well be down to personal preference.
There are two bases that can be purchased separately, a chrome ring or some wooden legs, that’ll increase its height and enhance its furniture-style aesthetic. Their prices are a hard pill to swallow, however, at a cost of $99.99 / £99.99 and $79.99 / £79.99, respectively.
The motion-activated controls on the top of the Blue Signature are responsive and easy to use, and remote controlling the purifier is straightforward on the well-designed Blueair app.
The app contains a host of useful features, including controls, automations, settings, and color-coded air quality graphs for up to a month of PM1, PM2.5, and PM10 readings.
In addition to the four fan speeds, there are three modes available. These are Auto mode, which sets the Blue Signature to purify at speed one until contamination is detected, Eco mode, which operates the same as Auto, but the purifier remains idle, and Night mode, which lowers the purifier to its lowest speed and turns off most of the lights.
There’s a useful AirSense automation that provides a quick freshen up twice a day when the Blue Signature is in Auto or Eco mode, which runs regardless of the ambient air quality, though it can be turned off if desired.
In terms of performance, I was very pleased with the Blue Signature’s efforts. It promptly detected and cleared the contamination caused as a result of my spraying dry shampoo from a couple of feet away, and displayed the readings in the graphs on the app.
It appears that the Blue Signature does a better job of tackling odors than other purifiers I’ve tested, as it made short work of removing the fragrance from the dry shampoo following my testing.
The Blue Signature operates satisfyingly quietly despite its power, maxing out at just 55dB at top speed, and giving readings as low as 27dB on speed one, which is quieter than a whisper.
As the brand makes some of the best air purifiers, it hasn’t come as a shock that there’s a lot to like concerning the Blueair Blue Signature. It has many helpful options and performs nicely at a pleasingly low quantity for the worth, making it the proper selection for bigger areas, with out being conspicuous.
Blueair Blue Signature review: price & availability
- List price: $449.99 / £369
- Launch date: Mid 2025
- Available now in the US and UK
The Blueair Blue Signature has a list price of $449.99 / £369, and is available to purchase directly from Blueair or at Amazon.
This is a pretty good price considering it’s designed for large rooms, supports WiFi connectivity, and can detect and react to PM1, PM2.5, and PM10, meaning it’ll jump into action whether ultra-fine or coarse particles are present.
What’s more, I’m already seeing some great deals appearing in the US, with Blueair offering a $50 off the price at the time of writing, so you can pick the Blue Signature up for just $399.99. I’m yet to spot a deal in the UK just yet, but you never know.
Blue Signature 4.0 replacement filters look a little pricey at $99.99 / £99.99 each, but Blueair states that these filters can last up to a year, and their RealTrack algorithm calculates the lifetime left on your filter based on the fan speed, usage time, and pollution levels, meaning it should offer a more accurate expiry date compared to other models.
It’s worth noting that while the all-singing-all-dancing 7-stage filter uses Blueair’s HEPASilent technology, it’s not a true HEPA filter, although Blueair has insisted that their filters are literally simpler and function at decrease volumes.
I examined the Blueair Blue Signature with none equipment, however there’s the choice of two completely different stand codecs if you wish to make it look extra like a chunk of furnishings.
These don’t come low cost, nonetheless, with the picket legs, known as the Leg Base in Wooden, costing $79.99 / £79.99, and the Ring Base in Chrome costing an eye-watering $99.99 / £99.99. As good an addition as these would make, I have to admit that I think about these grossly overpriced, which is a disgrace, as they might vastly enhance the aesthetic.
Equipment apart, contemplating the Blue Signature’s dependable efficiency, straightforward filter alternative, and easy controls, this Blueair air purifier provides loads of bang in your buck, even on the full listing worth, making it nicely value your consideration.

Blueair Blue Signature review: design and features
- Pleasantly lightweight for the size
- Four fan speeds, three purifying modes
- The material of the tabletop surface could be better
The furniture-inspired design of the Blueair Blue Signature makes it pleasingly subtle for an extra-large room air purifier.
The Blue Signature comes in a choice of Light and Dark models, the former being a mid-gray color, and the latter being a navy blue, which is the model I’ve tested.
Both models come with a color-coordinated machine-washable pre-filter, a Nordic Fog with the Light, and a Midnight for the dark. At the time of writing, the Blue Signature Light model doesn’t appear to be available at Blueair in the UK, but it can be purchased from Amazon.
If you feel like mixing things up, there are four other pre-filter colors to choose from, which include a couple of neutral colors, a blue, and a green. Each pre-filter has a list price of $24.99 / £24.99, so it’s not too much of an outlay if you want to change up the color, or have a spare to put on while the other is in the wash.
Although rather large, at 15.5 inches / 39.4cm in diameter, the Blue Signature is surprisingly easy to maneuver, as it weighs only 13.2lb / 6kg, and I could use the gap between the pre-filter and the top section to carry it about.
The Blue Signature’s 17.2 inches / 43.7cm height might prove a little low to use as a side table for some, but it’s not inconveniently short. The wooden legs would definitely prove beneficial here, but I think I’d rather prop it up on something than pay that price for the four-legged base.
The smooth matte plastic on the top of the air purifier makes it look like what it is, the top of an appliance, rather than an item of furniture. I would have liked to have seen a slightly more premium finish, but it offers plenty of surface area for placing mugs, books, and remote controls.
Speaking of controls, the touch controls on the top of the Blue Signature are pretty nifty, as the motion-activation means they disappear along with the display. They’re pleasingly simple to use, and include buttons for power, Auto mode, night mode, a display lock, and cycling through the four fan speeds. It’s quick and easy to change the settings on the app, too, so I could switch modes without needing to move out of my comfy spot on the sofa.
There’s a steady blue light under the top surface of the air purifier when the air quality is rated as excellent. It changes color depending on the level of contamination, and is automatically dimmed when the Blue Signature is put into Night mode.
When Auto mode is enabled, the Blue Signature fan runs at speed one consistently, increasing the speed to suit whenever the Blue Signature detects PM1, PM2.5, or PM10 contamination.
I appreciate that the air purifier continues to purify at a low speed despite the air quality registering at a good level, as many air purifiers simply idle on Auto mode, so they fail to react and purify the surrounding air of contaminants they aren’t capable of detecting, such as VOCs.
Lastly, there’s an Eco mode, which works much the same as Auto mode, except it sits dormant until contamination is detected, thereby conserving energy.

Blueair Blue Signature review: app
- Quick and easy device syncing
- Simple and straightforward interface
- Provides access to air quality graphs, settings, and automations
Adding a new device can be a headache in some cases, but as the Blueair app detected the Blue Signature straight away, I simply needed to select it and follow the instructions to connect it to my WiFi, which it did with no issues.
The Blueair app is simple to navigate, and the settings are easy to access and adjust on the dashboard for the Blue Signature. For day-to-day control, there’s a simple slider to amend the fan speed, buttons to enable each of the three modes, and the display lock function.
There’s a useful feature linked to the Auto and Eco modes called AirSense, which means that my air purifier would stir into action for ten minutes at 10am and 6pm every day, though it can run for as long as twenty-five minutes if the air quality is a little lower.
This is particularly helpful if you plan to keep your air purifier set to Eco mode, as the air will still get a little freshen up twice a day. If you’d rather it didn’t embark on these mini cleaning sprees, it’s easy to turn off in the device settings.
There’s also a schedule feature, which can be used to set the air purifier to power on in a chosen mode at set times on your choice of days, before turning off at an allotted time.
Another nifty automation is the Welcome Home feature, which powers on the Blue Signature when you’re approximately fifteen minutes away from home, based on your location and specified transport method.
A color-coded graph makes it easy to review the collected air quality data on the Blueair app. There’s a different graph for PM1, PM2.5, and PM10, with the option to view the readings over the course of a day, week, or month.
Overall, the app provides all the essentials in an easy-to-navigate interface, and all functions appeared responsive, bar the few moments it can take for the graph to update and reflect the real-time air quality readings.
Blueair Blue Signature review: performance
- Quick and easy setup
- Prompt detection and contamination clearing
- The dark tabletop appears to scratch easily
Getting the Blueair Blue Signature setup was a quick and simple process, as it was just a case of plugging it in and setting it up on the Blueair app.
I didn’t feel quite as comfortable using the Blue Signature as a side table as I did with the SwitchBot Air Purifier Table, because it felt a bit mistaken placing issues down instantly on prime of an air air purifier, and the fabric seems to be prefer it’d mark and scratch simply.
Whereas the darkish blue desk prime collected fingerprints simply, they wiped off with out a lot effort. This was a reduction, as some darker-colored matte surfaces can show notoriously tough to take away fingerprints from.
Sadly, it acquired a bit scratched not lengthy into my testing. Presumably, this was from me balancing the plug on it as I pulled it out of the field, although it was solely the plastic a part of the plug in touch with the floor, which is a priority contemplating it’s meant for use as a tabletop.
These scratches have been solely actually seen when caught within the gentle nonetheless, and sure extra noticeable as a result of darkish coloring of the plastic. Both method, I’d positively suggest implementing the coaster rule in your home when you plan to make use of it as a desk.
All the modes labored as anticipated. Evening mode decreased the fan to its lowest pace and extinguished the indicator gentle, the show, and many of the contact controls, although curiously, the Evening mode and energy button stay illuminated.
By way of purifying efficiency, I used to be happy to seek out that the Blue Signature solely took round sixteen seconds to detect the dry shampoo I’d sprayed round two toes away.
After detecting the contamination, the air high quality ranking was up to date to “very polluted”, and so the Blue Signature ramped up the fan pace. The air high quality returned to “good” ranges round twenty seconds from detection, and was again to “wonderful” after an extra minute, at which level the fan pace was decreased again to its lowest setting.
The Blue Signature appeared to clear odors higher than different air purifiers I’ve examined. Whereas the robust odor of the dry shampoo normally lingers lengthy after the air air purifier I’m testing has handled the particulate contamination, it was cleared pretty shortly by the Blue Signature.
This might be all the way down to the truth that the Blue Signature runs at its lowest fan pace in Auto mode, fairly than merely idling, which means it may show possibility if lowering ambient odors is in your listing of priorities.
I used to be impressed by the Blue Signature’s low quantity too, discovering that it operated quieter total than nearly all of the air purifiers I’ve examined up to now. The loudest studying I recorded was 55dB when it was working at prime pace, making it no louder than a dialog, and it operated at simply 27dB on fan pace one, which is quieter than a whisper.
Whereas the tabletop might depart just a little to be desired, all in all, the Blueair Blue Signature carried out very well. Its capability to purify an extra-large room’s value of air, in-app options, fast detection, and contamination tackling make this a terrific air air purifier for the worth, and, ignoring my private preferences on its suitability as a desk, it seems to be a complete lot extra enticing than any large-scale air air purifier I’ve come throughout up to now.

How I tested the Blueair Blue Signature
- I tested the Blueair Blue Signature over a few weeks
- I explored the Blueair app and tested the modes and features
- I tested the purifier’s detection and reaction speeds
After assembling the Blueair Blue Signature and syncing it to the Blueair app, I tried out the onboard touch controls and app-based controls before having a good explore of the different settings and features.
Along with using the Blueair Blue Signature passively in my home, I also conducted our standard testing procedure of spraying dry shampoo from around two feet away to assess its performance. I then assessed the air quality readings on the app to ensure they were aligned.
I measured the sound levels emitted from different fan speeds and modes, and compared these readings to the measurements I’ve taken from other air purifiers.
