As an incredibly quiet and efficient air purification solution, the Blueair Classic 405 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.
The HEPASilent™ purification system used in the Classic 405 is incredibly effective against many different airborne contaminants and allergens. This includes pollen, dust, PM 2.5, pet dander, mould, bacteria and viruses. It can also be effective against smoke when used with a SmokeStop filter.
At its highest setting, the Classic 405 can complete 5 complete air changes per hour, giving it an amazing clean air delivery rate. 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 405 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 405 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 405 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 405, Blueair has worked hard to make it very efficient when in operation. As a result, at its highest level, it only uses 90 watts of power and at its lowest level, it works at a mere 15 watts.
That efficiency also allows the Classic 405 to remain very quiet when in operation. When at its lowest level it can even operate at 32 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 405 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.
