Blueair replacement filters by model

Blueair's page says this filter is compatible with Blue Pure 211+ and explicitly not compatible with Blue Pure 211+ Auto. The Auto exclusion is material. Do not strip 'Auto' or treat the two similar names as aliases.

The US Blueair product page FAQ names both Blue Pure 211 and Blue Pure 211+ as compatible with this filter. Its product details separately say it is not compatible with Blue Pure 211+ Auto. This record uses the US source only. Match the exact label: original 211, 211+, 211+ Auto, and 211i Max are distinct entries. The Canadian catalog does not establish fit or current availability for the original 211.

Blueair states this replacement filter is compatible only with the Blue Pure 311 Auto air purifier. This fit claim is specific to the Auto model. A similar 311 name is not enough to establish compatibility.

Blueair states the filter fits only the Blue Pure 211i Max and offers several filtration variants under the same model-specific family. This is a separate Max model from Blue Pure 211+ and 211+ Auto. Check the purifier's label and select the OEM filter variant deliberately.

Blueair's US page names 411i Max and 411i+ Max; the official Canada catalog also lists 411a Max in the 411 Max filter family. Regional series wording varies. Confirm the complete purifier label and check the corresponding US or Canadian manufacturer listing; do not infer across older 411 / 411 Auto generations.

Blueair's official catalog lists several dedicated filter variants under the Blue Pure 511i Max name; the product family listing is used here as series-level evidence. A catalog family record is less specific than a standalone part page. Check the current filter product detail and purifier label for the exact variant before purchase.
