On the highest speed setting, the Blueair 405 has an airflow rate of 595 m3/h which is more than the 475 m3/h of the 450E. The size, weight, overall look and the filtration technology used however, is exactly the same. One of the new features of the Blueair 405 is its Wi-Fi connectablility, allowing you to connect to the air purifier via your phone and Wi-Fi network and make adjustments to how it operates.

Blueair have specified the airflow rate of the Blueair 405 as 204 m3/h on speed setting one, 339 m3/h on speed setting two and 595 m3/h on speed setting three. This is compared to the 450E’s airflow rate of 122 m3/h on speed setting one, 270 m3/h on sped setting two and 475 m3/h on speed setting three. The Blueair 405 is able to offer 5 air changes per hour based on a (40m2) room and a standard ceiling height of 2.4 metres.

Button C, below, is the filter life indicator, which will turn orange when it is time to replace the filter.

4. Design and Durability
The Blueair 405 uses the same casing, fan and filters as the 450E. The only difference is the air inlet and outlet which have been enlarged to enable the increased airflow rates. The Blueair 405 measures (23 x 20 x 11 inches) (58 x 50 x 28cm) and weighs (15Kg). As such, it can easily be positioned next to walls and in narrow spaces to preserve space. The Blueair 405 has a metal construction with a white/grey gloss finish and has the same style Blueair units are known for.

Below is a comparison table which shows what the differences are between the Blueair 400 series range of air purifiers.

 

The Blueair 405 uses Blueair’s typical Three-Stage Progressive Filter – a filter that resembles having several filters in one. The filter is made up out of three different levels of millions of ultra thin fibers, and with its ‘lock-in’ design, captures and retains particles. The first layers of the filter capture larger particles like pollen and dust, and the later layers capture smaller particles like bacteria and exhaust particles.

Regular air purifier filters are thinner and consist of the same fiber size and material throughout. This leads to filters being loaded sooner and either losing efficiency or requiring to be replaced. However, the unique design of the Blueair 405 Three-Stage Progressive Filter requires you to replace the filter only twice a year.

When the filter of the Blueair 405 needs to be replaced, just open the side door, and take out the old filter like you would take a book out of a bookshelf, then simply replace it with a fresh filter. No screws, hooks or tools are needed and replacing the filter only takes a couple of seconds.
