Blue Product Family Troubleshooting

Why is there a red light on my air purifier?

A red filter replacement indicator appears on the air purifier when it is time to change filter. 

The unit will show 3 red lights if the air purifier is on Auto Mode, or 1 red light if another fan mode is selected.

Reset the red light(s)

Press down the button until the red light(s) disappears (Usually takes 7-10 seconds and may take up to 30 seconds depending on the model).

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. 

How is Filter Lifetime Calculated?

The filter lifetime is calculated on the usage of the air purifier. The filter indicator light turns red after 6 months of operation.

The filter light indicator turns red after 6 months of operation of the air purifier to indicate to change filter. Press down the filter light or the button until the red light disappears (Usually takes 7-10 seconds and may take up to 30 seconds depending on the model).

In some Blue models, the filter light turns yellow after 5 months of continual use. This indicates that it will be time for your filter change in one month and it is time to order a new filter  Press down the control button until the yellow light disappears (Usually takes 7-10 seconds and may take up to 30 seconds depending on the model).

What type of filters are used in the air purifier?

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.

What is the recommended maintenance for the air purifier and the filters? 

• Vacuum the air purifier and its pre-filter
• Clean the fabric pre-filter in the washing machine
• Clean sensors according to the instruction in the user manual
• Replace the main filter when your air purifier indicates it is time to change it. To reset the filter light indicator, press down the control button until the red light disappears (Usually takes 7-10 seconds and may take up to 30 seconds depending on the model).

For more information, see the user manual.

My filter has a smell...

New filter​​:

• New products may emit an odor when opening the box, that is normal.​
• All materials have their own smell, including filter materials. The filter is enclosed by 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 starting 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. ​
• The average expected lifetime of the filter is stated for each Blueair product.​ However, the expected filter lifetime can be highly dependent on the environment the air purifier is in which could require more frequent replacement.​

Note: it is not possible to remove all odors, ventilation in addition to using air purifiers will help get rid of strong odors.​

The air purifier makes an unexpected noise​.

Expected noise with air purifiers​

High speed level: Air purifiers that are set on a high-speed level produce more noise because they function at faster rates. On low fan speed, the air purifier should be quieter.​ ​

Dirty filters and pre-filters: If the main filter(s) or pre-filter(s) are very clogged or dirty, the engine might not get sufficient airflow, which may result in increased noise levels. ​

Room environment: In an empty room with high ceilings and hard material there may be increased sound with the echo, compared to room with carpet and other furniture which may help absorb noise created by the device.​

If your air purifier makes an unusual sound ​

1.Turn off and unplug your air purifier​

2. Remove the main filter(s) according to the instructions in the user manual and make sure that you have removed the plastic cover from the filter (not applicable to all models and filters).​​

3. Make sure that there are no objects or dust: ​

• Inside the air purifier (for Blue air purifiers, look through the top of the unit).​
• Around the air inlets and air outlets​​
• On top of or directly against the air purifier​​
• On the pre-filters, if your air purifier has pre-filters​

4.Re-install the filter and pre-filters correctly.​

5.Ensure that the air purifier is with at least 10 cm from any objects or wall.​​

6.Make sure that the air purifier is standing stable on an even surface. ​​

If the noise continues​ please contact the Blueair Customer Support to get help. ​If you notice any damage on the device, please contact the Blueair Customer Support.
