As an incredibly quiet and efficient air purification solution, the Blueair Classic 680i offers quality throughout. Designed to be used in rooms as large as 40 m², it has been built to perform at the highest level and its HEPASilent™ technology can remove contaminants down to 0.1 microns in size.
In many ways the Classic 680i is nearly identical to the Classic 605, with the key exception of its inbuilt environment sensors. These allow it to detect and analyse the quality of the air in its surrounding environment and provide feedback based on the results.
As a result, the 680i provides a much greater depth of control, and its feedback can be used to save energy or improve performance. However, when fully utilised with the automatic operation mode, the sensors allow the Classic 680i to function independently and switch between speed settings to achieve optimal results.
The HEPASilent™ purification system used in the Classic 680i is incredibly effective against many different airborne contaminants and allergens. This includes pollen, dust, PM 2.5, pet dander, mould, bacteria and viruses. The included SmokeStop filter also allows it to be effective against smoke.
At its highest setting, the Classic 680i can complete 5 complete air changes per hour, giving it the best clean air delivery rate in its class. As a result, the impact it has on a room is almost immediate and it’s 99.7% effectiveness against allergens allows it to make a noticeable difference.
The filters used in the Classic 680i implement a gradient structure of ultrasonically bonded fibres, which allows for maximum airflow to be maintained while allergens are removed. The complex nature of this structure also prevents allergens from escaping back into the surrounding environment once they are captured.
Both the Particle and SmokeStop filters that are compatible with the Classic 680i have an expected life of 6 months or around 4,380 hours of use. As a result, they don’t need replacing too frequently and are easy to dispose of as they can be widely recycled.
Beyond its impressive purification ability, the Classic 680i is also very easy to control. Its inbuilt LED panel provides intuitive information and all of its functions can be controlled through a few touch buttons for a straightforward experience.
However, this is not the only option, as this purifier is also compatible with Blueair’s, free to download, app. This app can be installed on any smart device such as a phone or tablet and it allows the purifier to be controlled remotely once the unit has been paired.
To match the plethora of fantastic features offered by the 680i, Blueair has worked hard to make it very efficient when in operation. As a result, at its highest level, it only uses 100 watts of power and at its lowest level, it works at a mere 15 watts.
That efficiency also allows the Classic 680i to remain very quiet when in operation. When at its lowest level it can even operate at 33 dB, which is about the same as whispering in terms of volume. Therefore, this purifier is a great night-time companion that won’t impact the ease of sleep.
From a more basic perspective, the Blueair Classic 680i is also built to a very high standard. Its body is made of galvanised steel, giving it a premium feel and ensuring it is robust against continued use. It is also backed up by a 5-year warranty to ensure it can meet expectations should a fault occur.
