The Blueair Classic 680i is an advanced air purifier designed to filter the air in rooms up to 72 m². It makes a big impact by offering unparalleled purification and auto-adjusting sensing technology while remaining incredibly quiet and efficient when in operation. It also benefits from Blueair’s HEPASilent™ filtration technology, which can comfortably remove allergens and air contaminants as small as 0.1 microns.
Sensor Technology
At a base level, the Classic 680i is very similar to the Classic 605 model. However, it’s differentiating factor is its ability to sense and analyse the air around it. As a result, it can provide feedback on the quality of the surrounding air, and if desired it can be set to automatically adjust its speed setting to quickly deal with any detected issues.
HEPASilent™ Filtration
The Classic 680i is a very capable purifier, and it can remove an incredibly wide array of allergens and air contaminants down to 0.1 microns in size. This includes pollen, dust, PM 2.5, pet dander, mould, smoke, bacteria and viruses, to name a few. At its top speed setting, it can even complete five complete air changes in an hour, ensuring its impact is quick and very effective.
Additionally, the optimised gradient structure of the ultrasonically bonded fibres in the filters allows for the removal of these 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.
Protects Against Viruses
A critical role for any good air purifier is to filter out airborne bacteria or viruses. The Classic 680i excels at this purpose, and it is not only able to effectively filter out over 99% of harmful germs, but it can also prevent their reproduction. As a result, the air in the surrounding environment is safer to breathe.
Whisper Quiet Operation
Beyond its impressive filtration abilities, the Classic 680i is very quiet when in operation. At its lowest power setting, the outputted noise level is 33 dB, which is equivalent to whispering or light snoring and at its highest setting, the noise level is 62 dB, which is more noticeable and is similar in level to street noise. Therefore, it is a great nighttime purifier that can also find a home in many larger rooms and workspaces.
Environmentally Friendly
To match its quiet operation, the Blueair Classic 680i is very efficient to run, even for long periods. When used at its lowest setting, it has an output of just 15 watts, and it caps off at 100 watts at its highest setting. As a result, the Classic 680i is Energy Star rated as one of the best in its class.
Its efficiency is all thanks to the low dense design of its filters, which require less pressure to circulate air through them. Additionally, both the Particle and SmokeStop™ filters available for use in the Classic 680i can be widely recycled.
Built to Last
As one of the more premium air purifier options available from Blueair, the Classic 680i is a well-built machine. Its housing is made of galvanised steel, for a very durable structure that can handle plenty of movement and use. Furthermore, Blueair offers a great five years of warranty cover on it, guaranteeing incredible air filtration performance over many years of use.
Remote Control
To cap off an impressive package, the Classic 680i can be controlled remotely through any smart device that is compatible with Blueair’s free app. The app will pair the smart device of choice to the purifier through a Wi-Fi connection, allowing for operation settings to be changed at will for optimal home air quality.
Alternatively, the Classic 680i has an inbuilt digital control panel with touch buttons to control these functions. That control panel is also accompanied by LED indicators to show the current operating speed and filter status in an easy to understand format.
