The Blueair Blue Pure 311i Max Air Purifier: Designed for Any Home

Studies have found that we spend about 90 percent of our time inside. That means we should prioritize making our home a healthier space. But you don’t have to sacrifice style to do so. The Blueair Blue Pure 311i Max air purifier has a sleek Scandinavian design. Its white finish matches any aesthetic, making it a perfect addition for any room. Now, the Blueair Blue Pure 311i Max model works best in 387-square-foot spaces², cleaning it in just 12.5 minutes. In 929-square-foot rooms, it only needs 30 minutes thanks to HEPASilent™ technology. What’s more, you don’t have to worry about it disrupting your daily routines. Even little ones won’t be disturbed as they nap, as this purifier is never louder than 50dB³. At low, it runs at a soft 23dB.

Breathe Easier at Home

A comfortable home environment isn’t dependent on temperature alone. Air quality is just as important—especially if you or another household member has allergies. We love how every inhale feels like a breath of fresh air with the Blue Pure 311i Max air purifier. Its pre-filters are designed to last longer than primary filters, effectively trapping larger particles like pollen and pet hair. Keep an eye on your home’s air quality with the five-color indicator. You want to aim for blue, which means excellent. Now, you may be wondering…do you really need an air purifier? If we’re being honest, every home can benefit from one, and you can’t go wrong with the Blueair Blue Pure 311i Max model.

A Smarter, Cleaner Home

Whether you’re part of a large household or a small one, the Blueair Blue Pure 311i Max air purifier fits perfectly into your lifestyle. While you can use the top controls to adjust settings, we recommend downloading the Blueair app. Here, you can remotely change settings and pair to your smart assistant, unlocking voice commands. You’ll also gain access to Welcome Home. This feature puts the Blueair Blue Pure 311i Max into standby when you’re away. When you return, it automatically turns back on.
