But one thing every Blueair purifier has in common is that it makes use of the same patented HEPASilent technology. This technology charges airborne particles while they are still in the air, making it easier for the HEPA and carbon filters to capture them. increasing effectiveness and eliminating 99.99% of pollutants The Blueair Blue Pure 411 may be recognizable to you if you have previously conducted any kind of research into purchasing an air purifier. also you can check our article on Blueair Pure 411 review.

Blueair Pure 411 review: Design

The Blueair Blue Pure 411 Auto is the company’s smallest air purifier, standing 17 inches tall and weighing only 3.8 pounds. It has a kaleidoscopic, circular top that is really easy to get lost in. The skirt of the matte white plastic shell serves as a filter as you move down it. Grey, pink, blue, and green colored burlap-style pre-filters are available; they serve as the first line of defense but not the only one. There is also a deodorizing carbon filter and a HEPASilent filter, both of which, according to Blueair, can capture 99.97% of airborne particles. Because there is only one control on this air purifier—a single button on top—you won’t need to utilize any other controls. The device turns on and enters the auto mode when you press it once. This mode detects the air quality and selects the appropriate fan speed based on that. A light slit that changes from blue to orange to red can be seen on the device’s front. According to its sensors, that light provides information about the air’s quality. It continues to move slowly forward after detecting no problems at blue. If it strikes an orange or red object, it detects something in the air and works extra hard to remove any particles. By pushing the same button, you can choose between low, medium, or high, the fan’s three specific speeds. The front air quality monitor is turned off and the fan slows to a gentle hum when the fan is set to low, which also serves as the night mode. If you miss the option you’re aiming for, you’ll have to cycle through each mode to get to the previous one, which can become tedious.

Blueair Pure 411 review: Setup

There isn’t much to say either. You only need to plug in the Blue Pure 411 because the filter is already installed. If you’d want a little extra thrill, you can press the button on top. Another significant advantage of the Blue Pure 411 is how quiet it is at its usual speed setting. On full power, it’s a little noisier, but generally speaking, I don’t think you’d use it unless a terrible air-fouling incident has happened.


The controls for the Blueair are quite basic. It doesn’t have an automatic setting, an app, or a remote control. Simply tapping the top circle cycles through levels 1, 2, and 3; three white lights show which setting is active. The only thing this air purifier is really missing is smart controls, like an app or an air quality gauge. You might be okay without them because some people find this a little gimmicky in any case. The machine’s inability to automatically adjust levels, which prevents it from intuitively reacting to any changes in air quality, is a more significant drawback. In order to maintain good air quality quietly in a bedroom, you might want to turn it on briefly just before bedtime at a high setting. also you will learn our article on Blueair Pure 411 review.

Blueair Pure 411 review: Performance

The recommended room size for this air purifier is 190 square feet based on CADR numbers. When compared to other air purifiers or the Blue Pure 211+ Auto, the 411’s older sibling, that is a little underwhelming. However, given the small size of this air purifier, these findings are not unexpected. For smoke, dust, and pollen, it received CADR scores of 123, 107, and 96, respectively. The Blueair Blue Pure 411 Auto is more than capable of filtering these contaminants in small spaces, despite the fact that these numbers may seem low in comparison to those of other products we’ve tested. In comparison to many of the other air purifiers we tested, it used a respectable amount of power. It consumed.154 kWh when left in auto mode for 24 hours; for comparison, that works out to about 50 cents per day. But if you only need to clean a small room, the price might be justified for a good air purifier. And considering how small the tube was, it didn’t make much noise. At the slowest pace, its 32.5 decibel level barely registered above the room’s background noise. It achieved 51.6 decibels while blasting at maximum volume, however this was extremely low compared to other devices we tested. You can simply toss this air purifier in a corner and forget about it until it needs new filters because it is so small, quiet, and simple to use. However, we found that if you apply too much pressure when programming the device, it has a propensity to topple over.

Price and availability


One of our favorite air purifiers, the Blueair Pure 411, works best in compact apartments or workplaces. This cylindrical device looks sleek and is small and straightforward, but it eliminates airborne particles at an astounding pace. Even though it lacks some of the more advanced features found in its larger and more expensive competitors, we believe that this unit will work well for people who want to improve the air quality in small spaces or who want to travel with an air filter. Additionally, the Blueair Pure 411’s straightforward yet stylish design complements almost any decor, whether it be contemporary or traditional.
