Other Filters

Carbon activated filter is also part of the Classic Blueair 605, and that is one of the most important filters to provide an odor-free air. Carbon is proven to remove all the bad odors from the air. Prefilter in this air purifier has the same functions as pre filters in any other air purifiers, and that is to prevent clogging. By removing big pollutants with a prefilter, you are prolonging the life of the most important filter which is, in this case, HEPASilent filter.


We must agree that Blueair did not put too much of an effort into designing this air purifier to be one of the good looking air purifiers on the market. I would go so far as to say that this is one of the ugliest air purifiers you can buy. But is that what you want? A good looking air purifier or the best air purifier? I can, without a doubt, say that Blueair Classic 605 is one of the best on the market.

WiFi Enabled

There is not much to see on the box, and basically, you can not see anything interesting on the air purifier. This is not attractive air purifier with nothing to leave you breathless while watching at the device. But the good thing is that WiFi enabled air purifier has Blueair Friend App on which you can do many things.

Blueair Friend Application

Blueair Friend Application is one of the best things you can have when using Blueair air purifier. Through the application, you can remotely control the air purifier. You can turn it on or off while you are miles away from home. And not only you can manipulate the air purifier from a distance through the internet, but you are also capable of monitoring everything that is happening with the air purifier in the application on your cell phone.

With the mobile app, you can set child lock, turn on night mode, which will dim the lights for pleasant sleeping. At the same time, the air purifier will start working at a slower rate, but at the same time, it will be silent and sleeping friendly. If you like, you can also change the fan speed manually and turn it to maximum speed. This is a good option when you are at work, and you know you are coming home in one hour, then you just turn the air purifier to the maximum work and in one hour when you get home the air in the room will with at the highest possible quality.

WiFi enabled option also allows this air purifier to be used with Alexa. With Alexa, you can talk to your air purifier and do everything you can do with the app, but with Alexa, you are using your own voice at stating commands to the air purifier. I know this sounds cool and it is a good thing that this air purifier has this option because the money you pay for this device you better get something special in return. High air filtration performance is not enough when you are paying premium money for such a device.
