Once the Indicator turns red, there is nothing more to think about other, than to replace the filter as soon as possible. If the Indicator lights up in yellow, you should get about one month before your air purifier’s filter becomes inevitably useless.
Well, both Blueair 211+ and Blueair 411 have it, and you won’t have to keep diary notes. You know about that dot that lights up, and you know it’s time to replace the filter in your favorite new little helper? Yes, the Filter Reset Indicator. Blueair 211+ and Blueair Blue Pure 411 – Control ButtonsĪnother interesting and useful feature, that makes both air purifiers compatible with smart plug devices is the ability to remember the last chosen working mode in case the power is off for some reason. It is quite easy to use any of these air purifiers since their button can only switch between gears and reset the Filter Reset Indicator. You can find this button on the front side of a Blueair 211+ and the upper side of Blueair 411. With both air purifiers, you will be offered a single button that does it all, with the slightest touch. Like I previously mentioned, having multiple advanced features is just not a Blueair’s thing. Still, both air purifiers have some quite interesting features, out of which many are in common. This is what Blueair 211+ and Blueair 411 are based on, simplicity and convenience. Sometimes, you just need something simple that’ll work. I have to admit that having way too many buttons and options can sometimes be tiring and annoying because, in many cases, you simply do not have the time to try out all that’s been offered to you by the manufacturer. The more advanced features they had, the more difficult it was for me to call my last verdict. I’ve been testing a lot of air purifiers by now and giving my best to compare them in real-time challenges.
