This is by far the very best air purifier. It cleans the air in my large space quickly and has my apt always smelling clean. I love it. I plan on buying one.of the sleep collection for the bedroom.
I would recommend this to a friend!

Clicking sound

I like the shape and look however at low speeds it makes a clicking sound. I have to turn it off at night since it located in the bedroom. Annoying.
No, I would not recommend this to a friend.

Signature Model is the best Best Blue Air/LOVE!

The Blue Signature is their best model. I have 2. Love them. Stylish and quiet. Works beautifully. I work with a surgeon whose husband is a Pulmonologist. He researched air filters and said Blue Air came out on top. They have them all over their house. That’s why I bought them. I also have a small and larger Blue Air in different models but the Signature model is my favorite. Great product. The only model I didn’t like was the nighttime one with the alarm. The led light can’t be shut off and it illuminates your bedroom all night. But the Signature model is awesome!!

Amazing Results

I purchased this unit for my son a week ago just before they had their first baby. They live in a 100+ year house and the smell of old house was evident each time we entered. With a new born we wanted to provide the best breathing environment possible. This unit did not disappoint us one bit it, it simply provided amazing results. Highly recommended. Thank you.

Outstanding!! And Beautiful!

This is my favorite brand and favorite model! Beautiful, quite efficient. The only thing that would make it better is if the light could completely shut off at night so I could keep it in my bedroom at night. There is always some light emitted. Perfect for the living room though.
I would recommend this to a friend!

Beautiful, but with fatal flaws
on October 1, 2025

It looks great, I love that it tracks air quality in the app (and the app is easy to use) but it has some fatal flaws if you intend to use it in a bedroom. Firstly, the blue light cannot be turned off unless the device is in auto mode. Turning the light down in the app to ‘0’ still leaves it on. This is disturbing at nighttime if you need to use anything stronger than night mode (I.e. we crack a window open for CO2 but often get hit with sudden smoke. Secondly, there is a huge difference between fan speed 1 (very quiet) and 2. At very low speeds the device makes a mild clicking sound rather than a ‘smooth’ sound like a previous purifier I had. When turned up to 2 (and also mask this) though it’s loud enough to be disturbing. I.e. over 40 decibels. Fan speed one doesn’t seem strong enough though for smoke ingress. This is clearly a device suited only to a lounge space where lights and the noise of a medium mode don’t matter.
For the team, improvements would include the ability to turn the blue light off completely (this seems like a real design flaw) and less of a jump between fan speeds 1 and 2 to give more options at the lower end.
No, I would not recommend this to a friend.

Thank you for sharing your detailed feedback on the Blue Signature™ Nordic Fog. We’re glad to hear you enjoy the design and app experience. For nighttime use, the blue light can be dimmed or switched off by setting the unit to Night Mode, or by adjusting the display brightness in the app, which lowers both the top display and front indicator. Since the clicking sound you described isn’t expected, we’ve reached out directly to better understand what’s happening with your unit.

The air filter works well, no complaints. Unfortunately, the device is equipped with a much larger than normal wall plug, and in my situation, the plug is making a cabinet stand out from the wall a good inch farther than is desirable. An short extension cord would solve this problem, but the instructions say not to use an extension cord!! A bit of info about the plug in advance would have helped soften this otherwise rather unpleasant surprise. Even better would be advice on how to deal with this type of problem.
