Blueair replacement filter

Blueair Blue Pure 211i Max

Blueair lists the F2MAX Particle + Carbon filter specifically for Blue Pure 211i Max. The retained Amazon option is one genuine F2MAX filter, not a filter for Blue Pure 211+ or 211+ Auto.

Models listed by the manufacturer

  • Blue Pure 211i Max

Models checked: US. Match the full code on your label.

Where is my model number?

Before you buy

  • F2MAX is not the replacement filter for Blue Pure 211+ or 211+ Auto. Check the full name on your label.
  • The fabric pre-filter and the main Particle + Carbon filter are different components. Match the complete item and pack on Amazon.
  • Our France OneLink check selected a different SmokeBlock variant. The standard-filter button stays on Amazon.com; the separate international link is a reference search, not an approved local product.
Find the complete model code
  1. Read the full model name on the purifier label.
  2. Confirm that it says 211i Max, including both the i and Max suffix.
  3. Match F2MAX on the exact product page before ordering.
Filter and fitting details
  • The i and Max suffixes are part of the model identity. This record covers Blue Pure 211i Max only.
  • F2MAX is the standard Particle + Carbon reference. AllergenBlock and other specialist variants are separate products.
  • Blueair says the main filter can last up to nine months depending on use. Its filter indicator and model instructions take priority over a universal calendar rule.
