Blueair Blue Pure 411 Air Purifier
The Blueair Blue Pure 411 is a compact and sleek air purifier designed to filter the air in rooms up to 15 m². Its greatest strength lies in its versatility and design, but it also packs a fantastic combination filter to remove a wide array of air contaminants. Those advantages have also been paired with whisper-quiet and efficient operation levels to create an impressive package.
Despite its size, the Blue Pure 411 is one of the most capable purifiers on the market. This is mainly thanks to its combination filter, which can remove a wide array of allergens and air contaminants. This includes pollen, dust, PM 2.5, pet dander, mould, smoke, bacteria and viruses, to name a few. Additionally, since the combination filter has an active carbon section, the 411 is also able to remove smoke, odours, gases and VOC’s, which can’t be achieved with a standard particle filter on its own.
The combination filter used in the Blue Pure 411 also features an optimised gradient structure, which allows for the removal of allergens and contaminants while maintaining maximum airflow. That structure also prevents the release of captured contaminants back into the environment, including bacteria and moulds. Each filter has a life of 6 months or around 4,380 hours when used to its maximum limits.
Beyond its filtration ability, the Blue Pure 411 is also quite aesthetically pleasing, which is the result of its clean and modern design. Its compact nature also allows it to fit effectively in many different environments. Therefore, to ensure it matches the style of any room it is placed in, Blueair has built the 411 to adapt. By default, it is supplied with a blue fabric pre-filter, but this can be swapped for other optional colours such as red and grey.
One flaw of many air purifiers is that they can be complicated to use and understand. However, with the Blue Pure 411, this certainly won’t be the case as just one button is used to activate it and to cycle through settings. The button also indicates when the current filter needs to be replaced.
Whisper Quiet Operation
Above all else the Blue Pure 411 is insanely quiet when in operation. At its lowest power setting, the outputted noise level is a mere 17 dB, which is about as loud as breathing, and even at its highest setting, the noise level is only 46 dB, which is similar to moderate snoring. Therefore, it is one of the greatest nighttime companions around when it needs to be.
To match its quiet operation, the Blueair Blue Pure 411 is unbelievable efficient. When used at its lowest setting, it has an output of just 1.5 watts. To put that in perspective, that’s less than your average small LED light. Even at its highest setting it only uses 10 watts of power. Therefore, it is no surprise that the 411 is Energy Star rated as one of the best in its class. As a bonus, its filters are fully recyclable, keeping its footprint very small.
