The air purifier calculates the remaining lifetime of the filters based on usage and sensor readings, and indicates when it is time to replace the filters.

How to reset the filter light indicator?

Press the Fan Speed button for 15 seconds to reset the filter timer

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. ​​

The firmware of my device is updating. How much time does this take?

The app notifies you every time the firmware in your device is being updated.

During the update, you must keep your air purifier connected to the Wi-Fi to have the firmware update complete. It is imperative you do not unplug the air purifier from the wall during any firmware updates.


The update should take a few minutes. Please do not disconnect your unit during the update!
If the update takes longer than a few minutes:

• Ensure your air purifier is within the router range.
• Leave your air purifier ON and connected to the WiFi. Do not unplug the air purifier during the update.
• Limit the number of connected devices or network activity while the update is in progress.

• Turn off the Wi-Fi network.
• Attempt to connect to a different Wi-Fi network or personal mobile hotspot.
• Upon connecting to a new Wi-Fi network or hotspot, the device will attempt to update again.

1. Turn off and unplug the air purifier ​​

2. Check the power cable:

​If your air purifier has a removable power cable, plug the cable firmly into the power cable socket on the air purifier. If the power cable is damaged, contact the Customer Support

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

• Inside the air purifier, on top of or directly against the air purifier​, around the air inlets and air outlets​.
• On the pre-filters, if your air purifier has pre-filters.
• Around the air quality sensors, if your air purifier has integrated sensors.

4. Check the filter: ​

• Make sure that the plastic wrapping around the filter is removed​.
• Insert the filters and make sure they are correctly inserted​​.
• Make sure the filter door is completely closed, or that the top of the air purifier is correctly attached to the bottom.​​

5. Confirm that your device is functioning:

• Plug the power cable firmly into an outlet.​
• Press the On/Off button to turn on the air purifier and select a speed level. If the air purifier does not have a On/Off button, directly select a fan speed from the control panel.​​
• Make sure that the LED indicators on the air purifier are lighting up​.​
• Make sure that the airflow is working (feel with your hands that air is coming out from the air outlet)​.

The DustMagnet air purifiers have a built-in sensor to monitor the indoor particulate matter levels (PM).

Particulate Matter (PM)* peaks are normal and expected to happen temporarily, even when the air is of good quality because your air purifier’s sensors react each time the air purifier is in contact with airborne particles or gases.

Pollution from outside coming in from open windows or ventilation may also cause high PM levels.​

​How to decrease the particulate matter (PM) and Volatile Organic Compounds (VOCs) levels and improve your indoor air quality?

• Make sure that the air purifier is used in an adapted room size with closed windows and doors. ​
• Set the highest speed of the air purifier temporarily or use the Auto Mode
• Avoid excessive use of perfumed substances, cleaning products, or other VOC contributors​
• Ventilate the room regularly and see if the PM and tVOC level lowers.
  • If the level of tVOC lowers when the windows are open and stay at the same level when windows are closed, then the device is detecting a gas that cannot be removed by the air purifier.
  • If the level of PM stays high even when you open the windows : ​Clean the sensors.on your air purifier. If the PM levels are constantly very high, there might be accumulated dust on the sensor giving a false indication.

Vacuum clean the air purifier from the outside at every filter change, especially around the sensors area (see picture)

*Examples of PM sources: candles, smoke, cooking, incense, fireplace, accumulated dust, unfiltered vacuum cleaner, pollen, pets, etc.
**Volatile organic compounds (VOCs) are gases and odors emitted from different chemicals. VOCs can be found within the air in your home; they are released by cleaning products, cosmetics, carpeting, furniture, air fresheners and many other consumer products.
