Three layers of ultra-advanced filtration

An outer fabric washable pre-filter starts the process by removing larger particles. This also extends the life of the main filter. 

The main particle filter removes everything from pollen, dust and pet dander to viruses and bacteria.² 

Then a layer of activated carbon goes to work, ridding households of light odors from pets, cooking and smoking.

Pre-filter for extended filter life

While the colorful fabric of the washable pre-filter looks great, it also extends the life of its primary filter by catching large particles. Its fabric can be vaccummed or put in a washing machine for easy cleaning.

Blueair Blue Pure 411+ unit specifications

Guarantee clean air for years to come with up to 2-years of warranty coverage when you register your air purifier.

How does this model differ from the Blue 411?

The Blue Pure 411+ builds on the functional design and performance efficiency of the original Blue Pure 411 model with an increased Clean Air Delivery Rate (CADR) and room size capacity (185 ft²), at relatively the same compact size as the original.

I've replaced my filters, now how do I reset the filter replacement indicator?​

Press and hold down the LED button for 10 seconds to reset the replacement filter indicator. ​​

How do I register for warranty?

To extend the Limited Warranty from one year to two (2) years, simply complete the product registration form in the 'Warranty' section of your customer account, within (60) days of purchase or register through the Blueair mobile app.​

Can I place the Blue Pure 411+ on my desk at the office?

Yes! The Blue Pure 411+ is compact and lightweight making it easy to place anywhere including your desk or countertop. However, to get the most out of your air purifier and effectively clean the air you're breathing, an air purifier’s performance should be based on the total square footage the space you will be in – not just the immediately surrounding area. Be sure to purchase based on the total size of the space you'll be in. We offer business solutions for larger office spaces, which you can suggest to your office management to consider. 

Why is my LED yellow?

The LED indicator will turn yellow after 5 months of operation to warn that it's almost time to change the filter. When the indicator light turns red (one month later), it’s time to change the main filter.

Where should I place my Blue Pure 411+?

The Blue Pure 411+ is compact and lightweight in size, and sleek in design, making it easy to place anywhere – ideally in a more central, open location of the room you're using it in. This way, it's able to most effectively capture the airborne particles in your space and let out clean, fresh air in return.
