  • Performance Specs Your Blue Pure 211+ Auto Filter Supports

    The Blue Pure 211+ Auto is certified to clean the air in a 550 ft² room 4.8 times per hour, with a CADR of 353 cfm for smoke and 380 cfm for pollen - performance figures that depend entirely on using a genuine, correctly fitted replacement filter. Fitting a non-Auto filter reduces these CADR values and voids the warranty. The 211+ Auto operates on Auto mode, using an integrated particle sensor to adjust fan speed in real time based on detected pollution levels, running from a whisper-quiet 23 dB on low to a modest 56 dB on high - roughly the volume of rainfall. Blueair's proprietary RealTrack algorithm tracks the remaining filter lifetime based on fan speed, usage time, and pollution levels, alerting you when replacement is due so CADR performance never degrades unnoticed. This Particle + Carbon filter is the only replacement certified to maintain those figures cycle after cycle.

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.

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.
