Using a filter which is filled with dust or saturated with odours will not bring dangerous components to your home. But if the filter is full, it may be difficult for the clean air to come out, and it might damage the air purifier in the long run. For best results and to guarantee a valid warranty*, we recommend changing the filters according to the indications.

*The Blueair Limited Warranty applies only if the air purifier is installed, used, and maintained according to the instructions in the user manual.

No. Use the SmokeBlock filters in replacement of the standard Particle + Carbon filters, for extra protection against wildfire smoke and emissions.

SmokeBlock filters are compatible with the following Blue air purifiers:

Blue Pure 211+/221 Series: 211+/Blue 221 and 211+ Auto/Blue 3610.

Blue Pure 311 Auto/3410 Series: 311 Auto/Blue 3410.

Blue Pure 411 series/Joy S: 411, 411+/Joy S, and 411 Auto/Blue 3210.

SmokeBlock filters can be used as replacement filters in Blue air purifiers, instead of the standard Particle + Carbon filters. The SmokeBlock filters offer extra protection against wildfire smoke particulates and emissions (toxic gases, smog, and odours), in addition to protection against airborne particles (dust, smoke, pollen).

SmokeStop filters can be used in Pro air purifiers instead of the standard Particle filters. The SmokeStop filters offer extra protection against gas, smoke, and VOCs, in addition to the standard protection against airborne particles (dust, smoke, pollen).

DualProtection filters can be used in Classic air purifiers, instead of the standard Particle filters. The DualProtect filters offer protection against gas, smoke, and VOCs, in addition to the standard protection against airborne particles (dust, smoke, pollen).

The Blue Pure Fan and Pure Fan Auto use a main Particle filter and a fabric pre-filter.

The main Particle filter captures large particles for purifier air circulation. The fabric pre-filter comes in different colours to fit your style and can be easily vacuumed and washed in the washing machine.
