The Blueair 450E HepaSilent Digital Air Purifier is designed for rooms approximately 365 sq. ft. in size and in a room of this size it can cycle all of the air up to five times per hour.

Exclusive SurroundAir technology draws dirty air in from all sides and gently diffuses air through an area six times greater than the average air cleaner.

The Blueair 450E uses HEPASilent technology and electrostatic technology to remove up to 99.97% of airborne particulates as small as 0.1 microns.

It is suitable for people with allergies, asthma, other respiratory conditions, or for anyone who wants cleaner, more breathable air.

This unit has four different airspeed settings and on auto mode, it will automatically adjust the operating speed according to the level of airborne particles and gaseous compounds.

The Blueair 450E air purifier is the same as the Blueair 402, except the 450E comes with a remote control and digital display system to give you instant feedback of particle detection, air purifier speed and timer operation.

So you don’t have to leave your comfortable spot at your desk, on the sofa or in bed to change the speed setting. Just point and click. Plus you can see when its time to change the filters on the electronic display.

The Blueair 450E HepaSilent Digital Air Purifier is one of the quietest operating air purifiers and features quality construction with an all metal outer casing.

There is an upgraded Model 450E that includes smokestop filter. This granulated carbon provides better odor removing capabilities compared to relying on a thin, activated carbon pre-filter.

User Reviews

When researching the Blueair 450E HepaSilent Digital Air-Purification System we found about a dozen reviews online and the reviews were quite good. One reviewer points out that this machine is not silent but it is reasonably quiet on the lowest speed but some of the other reviewers are saying that it is extremely quiet with one person saying it is so quiet in fact that sometimes we forget to switch off in the morning.

The Blueair 450E is a durable machine with an all metal case construction and a very powerful fan. It also does a great job of purifying the air. One person said that they had been suffering from a very bad sinus infection for over seven weeks and they were on three different antibiotics. After purchasing the Blueair 450E they said that it has made a huge difference and that they no longer wake up with clogged sinuses in the morning. Another reviewer says that when they are having a really bad allergy attack they can go into their room and turn on the Blueair 450E and in a couple of minutes everything clears up. They said that this thing is better and faster than taking medicine.

There are not a lot of reviews online for the Blueair 450E HepaSilent Digital Air-Purification System but the reviews that we did find were fantastic and after reading all of the reviews we can confidently recommend this air purifier.

On the negative side, there were complaints related to the remote operation and auto function. Also, while relatively quiet on low speed, the noise on the high speed might be too high for some users.
