Where to get Blueair Blue Pure 311 Auto Air purifier?
The Blue Pure 311 Auto has a completely new design from the rest of the Blueair family. However, we already talked about these changes in the review of the Blue Pure 411 Auto, so it’s tempting to say them again. Blueair may not have changed the look of the front of the Blue Pure 311 Auto, but the color is great. You get the Arctic Trail version by default, but you can ask Blueair for your preferred option. All of these colors are based on the nature of Scandinavia, and that’s how you can tell that they were made in Sweden.
The most important thing an air purifier does is get rid of irritating and harmful particles in the air. However, if the motor and fan make a lot of noise, it’s not worth it. The 311 is a pretty quiet device, which is good. When turned up to its highest setting, it only makes 56 decibels of noise at 6 feet. The high setting also makes a whirring sound, but because it’s not very loud, most people don’t notice it. As the speed goes down, so do the decibels and the whirring, until you reach the low/sleep setting and the 311 is almost silent.
The Blue Pure 311 Auto is recommended for medium rooms that are no bigger than 388 square feet. This room coverage has been approved by AHAM, so you can even use it in a much bigger room. Blue Pure 311 Auto has a 5X ACH. Blueair is a well-known company that makes powerful air purifiers. Its air purifiers can clean a room the size of which has been measured by AHAM 5 times per hour. The CADR (cubic feet per minute) for Blue Pure 311 Auto is 244 Dust/ 250 Smoke/ 250 Pollen. The fan power isn’t quite as strong as the Blue Pure 211, but it’s still one of the best in the low-to-mid range.
