customer review blueair 450e

My husband and I have been living in London for four years now, and enjoy it very much. However, there are some downsides, such as the high level of air pollution in the city. At first, I did not notice it, but after a little while, the pollution level became very apparent. You just have to blow your nose after taking the tube or look at the collar of your shirt at the end of the day and you will see what I mean.

I started looking for an air purifier. At first, I casually checked my local Tesco and Argos stores. I knew the quality of the air cleaner might not be the best, but I wanted to know my options. The salespeople in both stores did not know very much about the purifiers they were selling or air purifiers in general. I had to trust the manufacturers’ claims listed on the box. Most of these claims were too good to be true and often confusing. I could not shake the feeling that I could be buying just another ‘gadget’ that would not work and would end up cluttering my closet - just like the ‘reasonably priced’ iron I bought a little while ago at Argos. It was cheap, but it did not iron, and in the end, it was £25.00 wasted.

From the research I did on air purifiers, I know the unit needs to produce enough clean air to make a difference in our bedroom. Most units I saw were either too small or did not specify how much clean air they produced - which made me very sceptical. The purifier should also have a filter, ideally a HEPA filter. If the purifier does not have a filter, where does the pollution go? Another thing that was important to us was the sound level. The air purifier must be very quiet because my husband is a light sleeper.

In the end, I decided on a Blueair air purifier unit. There is a range of different models, but we thought the Blueair 450E air purifier would be the best choice for us.  It ticked all the boxes in terms of what we were looking for. It generated enough clean air for our bedroom, but also for our large living room, in case we decide to move it there. It does not have a HEPA filter but instead has a 'HEPA-like' filter, which is supposed to capture almost all particle pollution. (I was told that the difference between a HEPA filter and a HEPA-like filter is that the HEPA-like filter needs to be replaced more often - every six months and does not have the same high and consistent filtration efficiency). The unit also promised to be extra quiet. Additionally, I liked having the option of using a smoke-stop filter at a later point.

Ordering online at was very easy, and the air purifier arrived the next morning. I was very happy to see that there were no hidden costs. The purifier was very well packaged, with several layers of foam support on all sides. Besides the air purifier, the shipment came with a user manual, power cord and a manufacturer’s warranty card. The Blueair 450E has a solid grey colour down the middle and an off-white colour on the sides. I was pleased with the design and colour combination because it blended in well.

When I turned the 450E on, its electronic display came on, and the unit was already set on “Automatic” mode. When the Blueair 450E is on automatic, it assesses the pollution level in the room and chooses the appropriate speed setting. This is quite practical because we don’t have to think much about changing the settings. In the compartment next to the display, which is on top of the unit, there is a remote control. On level one, the Blueair 450E is near silent. I put my hand in front of the purifier to feel the air flow, to make sure it was running. One of the side panels opens for when it is time to exchange the filter.

The Blueair 450E is now in our bedroom and it is always on, alternating most of the time between level one and two. Sometimes we put the setting on level three. We have had the unit for four weeks now and I can truly say that we are very happy with it. My husband and I have even decided to buy a 650E for our living room. Thank you Allergy Cosmos for a great product and service!
