Blue Pure Max filter care: replace the main filter, wash only the fabric pre-filter

Official Blueair guidance distinguishes its 6–9 month filter reminder, non-washable main filter, washable fabric pre-filter and post-replacement reset.

Not every purifier filter is washable. Blueair’s Blue Pure Max family uses a replaceable particle-and-carbon main filter and a fabric pre-filter that may be cleaned according to its label. Replacement alerts and app status are more useful than a universal calendar rule. Exact opening and installation steps vary by model.

1. Identify the exact Blue Pure Max model on the unit or in the app and get a genuine replacement filter compatible with it.
2. Watch for the red filter replacement indicator. Blueair estimates roughly six to nine months for this family, but usage, air conditions and model affect the interval.
3. Switch off and unplug before handling the filter. Open the housing and remove the old main filter only as directed by your specific model manual.
4. Do not wash, vacuum or reuse the particle-and-carbon main filter. Install the correct new one according to the manufacturer instructions.
5. Remove loose dust from the fabric pre-filter with a soft-brush vacuum attachment. If washing it, follow its care label and hang it to dry fully before fitting.
6. Reset the reminder after replacement. Blueair describes holding the fan-speed button for about 15 seconds on Blue Pure Max; verify the exact controls for your model.
