Blue Pure

The Blue air purifiers use one main filter and one pre-filter:

Main filter

• The standard main filter is a Particle filter with a Carbon mesh for particle removal and gas reduction.
• 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 gasses, smog and odors), in addition to protection against airborne particles (dust, smoke, pollen).

Pre-filter

• The pre-filter is a fabric personalizable pre-filter that can be vacuumed and washed in the washing machine regularly (washing instructions can be found on the label of the pre-filter). The pre-filter catches large particles and protects the main filter inside the air purifier.

Blueair recommends to change filter after six months of use. If you use your air purifier in a highly polluted environment, you may need to change filter more often.

A red light appears on the air purifier to indicate when it is time to change the filter, after 6 months of operation.

The Blue 411 Auto/3210, 311 Auto/3410 and 211+ Auto/3610 air purifiers have integrated particle sensors to detect and indicate the particles levels in the room

In Auto Mode, the air purifier is always running at the perfect speed needed to maintain the purity of the air:

• Automatically adjusts the airflow according to PM2.5 levels
• Allows efficient speed operation, the fan increases progressively to the right speed based on the PM2.5 readings and slows down when the air is clean again.

As with any new product, a slight odor may be noticed that is inherent to the material. While we have optimized our manufacturing processes to minimize new product smell, in rare cases some smell is still noticeable.

New Product or Replacement Filter:

• New products may emit an odor when opening the box, that is normal.
• All materials have their own smell, including filter materials. Many filters are packaged in a plastic bag and a cardboard box, and the smell from the product is accumulated inside. The smell from filter media is harmless.
• Run your air purifier and ventilate your room to air out the air purifier and its filter to reduce the new filter odor faster.
• You may also place the new filter by an open window before using it or run your air purifier in a room where you spend less of your time, just for a few days until the odor fades away.

Any questions, please reach out to our Customer Support teams.

Used Filter / Filter used in strong odor environment:

• When the filter is full and gets saturated it can start to release a smell, and we recommend replacing it.
• Blue air provides an average expected lifetime of the filter which varies between products. However, the expected filter lifetime can be highly dependent on the environment the air purifier operates in which could require more frequent replacement.

Note: it is not possible to remove all odors, ventilation in addition to running the air purifier will help get rid of new product odors.
