1. Easy to Operate
The Blueair 450E air purifier offers a digital display system and a remote control.
On the digital display you can control which speed setting the unit is running on and the timer on the display lets you set the unit to run for one, two, four or eight hours or to let it run continuously. You can also change the settings of the 450E with your remote control, making operating your Blueair 450E as convenient and easy as possible.
Furthermore, the Blueair 450E’s display features an intelligent filter life indicator telling you when it is time to change the filter.

2. & 3. Ultra Quiet
The 450E uses Blueair’s patented 'HEPASilent technology'. This filtration technology is not actual HEPA filtration but is a combination of mechanical and ionisation filtration, and allows the Blueair 450E to deliver more clean air at a faster rate with less noise than other domestic air purifiers in its price range. Blueair’s HEPASilent technology allows the Blueair 450E to have exceptionally low energy consumption and run whisper quiet on setting one and two of its three speed settings.

4. Design & Durability
The Blueair 450E has a sleek and contemporary look that the Blueair air purifiers are famous for. It is built with a galvanised steel housing that is impact resistant and easy to clean. The Blueair 450E filters consist of non-toxic polypropylene media that is free of harmful triclosan fibers.

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


The Blueair 450E 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 450E Three-Stage Progressive Filter requires you to replace the filter only twice a year.

When the filter of the Blueair 450E 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 the new filter. No screws, hooks or tools are needed and replacing the filter only takes a couple of seconds. Just like picking a book out of a bookshelf and replacing it with a new one.

The Blueair 450E air purifier can also be used with the 400 Series SmokeStop replacement filters, which adds 1kg of carbon for additional odour and gas filtration.

Blueair 450E Air Purifier

I am very happy with my purifier. It does what I require by cleaning the air in my room were I keep birds. I researched air purifiers and this product rated highly. So far I have found it excellent. It was expensive so I would expect it to perform well.

Blueair 450E Air Purifier

Only used it for 2 days but great so far. The air in our bedroom feels crisp and clean. We now sleep with the window closed which cuts out noise too. Remember to switch it to no 1 at night rather than Auto - the first night I got woken by a great whirring sound at 4am when it automatically turned up the speed. On the lowest setting it is almost silent.
