Blueair replacement filters by model

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.

The Canadian Blueair page names the Blue Pure 311i Max and states compatibility only with that purifier model. This is Canada-market evidence. It does not establish price, stock, warranty terms, or equivalent listings in other countries.

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.
