FAQ
What Blueair models are compatible with this filter?
This filter is compatible with the Blue Pure 211+ Auto model only. If used with the standard Blue Pure 211+ model the clean air delivery rate (CADR) will decline.
If the position of the main button is on the top of the air purifier, you have a 211+ Auto model and this filter is compatible.
How do I know when it’s time to change my filter?
A filter change indicator light that will alert you when it's time to replace the filter. You can also check the status via the Blueair app for models with smart capabilities.
What is a filter subscription?
Purchasing a filter subscription saves you 15% on all future replacement filter orders + free shipping. At the time of purchase, the subscription will automatically schedule filter deliveries at the recommended six months. You can always adjust this timeframe from the 'My Account' section.
Are Blueair filters HEPA?
No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency - with less energy and noise.
What is the CADR of the Blue Pure 211+ Auto?
The Blue Pure 211+ Auto achieves a CADR of 353 cfm for smoke and 380 cfm for pollen. Using a genuine replacement filter is required to maintain these AHAM-certified CADR performance levels.
Is this replacement filter compatible with the standard Blue Pure 211+?
No, this filter is designed exclusively for the Blue Pure 211+ Auto model. Using it in the standard 211+ reduces CADR performance. Confirm your model by checking if the main button is on top.
