Does your exact model share this filter?

Dyson labels several versions of the Purifier Big+Quiet Formaldehyde BP04. Check the label on your unit.

  • Purifier Big+Quiet Formaldehyde BP04 takes 972132-01
  • BP04 same filter · Dyson model code
  • BP03 same filter · Named on the HEPA filter page; not on the K-Carbon page
  • BP02 not confirmed by Dyson · In the same demand entry; no Dyson filter page read names it

Look-alike models that take a different filter

The small Pure Cool Me (BP01) takes the TP01/TP02 glass HEPA filter, not the Big+Quiet filters.
