You can also use the basic functions of the air purifier without the "beurer FreshHome" app. The additional features, such as recording the ambient air values and setting a cleaning schedule, as well as controlling and monitoring your device when you are on the go, are only available in conjunction with the "beurer FreshHome" app.
LED light ring colour | Air quality | PM 2.5 value in µg / m³ |
Blue | Good | ≤ 12 |
Yellow | Acceptable | 12.1 – 35.4 |
Orange | Poor | 35.5 – 55.4 |
Red | Very poor | ≥ 55.5 |
The air purifier has a total of four fan speeds (I, II, III, IV) and three modes (TURBO mode, AUTO mode, NIGHT mode).
I | Low fan speed |
II | Medium fan speed |
III | High fan speed |
IV | Very high fan speed (all LEDs on the fan speed indicator 11 light up) |
AUTO | (LEDs I, II and III all flash at the same time) In AUTO mode, the fan speed is automatically adjusted in line with the ambient air quality. This means that the poorer the quality of the ambient air, the higher the fan speed automatically set by the air purifier. To activate AUTO mode, press the fan speed button 10 until all LEDs on the fan speed indicator 11 flash. To deactivate AUTO mode, press the fan speed button 10 again. |
TURBO | (LEDs I, II and III and the UVC indicator 13 flash at the same time) To activate TURBO mode, press and hold the fan speed button 10. In TURBO mode, the air purifier is operated at the highest speed, and the UVC light is also switched on. The TURBO mode switches off after 15 minutes and the device then switches to AUTO mode. To deactivate TURBO Mode early, press the fan speed button 10 or the UVC/sleep button 12. |
NIGHT ![]() | (Sleep indicator 14 lights up) In NIGHT mode, the air purifier is ultra-quiet and all light sources on the control panel 1 are switched off. To switch on the NIGHT mode, press and hold the UVC/sleep button 12 while the air purifier is switched on. The sleep indicator 14 lights up. After 5 seconds, all light sources on the control panel 1 are automatically switched off and the lowest fan speed I is activated. To exit NIGHT mode again, press and hold the UVC/sleep button 12. The sleep indicator 14 goes out. |
The UVC light eliminates germs in the air. When this happens, the UVC light activates titanium oxides that break down foul-smelling odour molecules (caused by tobacco smoke, cooking smells or animals).
The air purifier features a timer function that you can use to determine the number of hours the air purifier should run for before it automatically switches itself off. You can set three different timer times (2, 4 or 8 hours) on the control panel of the air purifier 1 .
NOTE: If you have connected the air purifier to the "beurer FreshHome" app, you can set an individual timer from 1 to 24 hours in the app.
We recommend replacing the filter 8 with a new one after 4320 operating hours. The filter indicator 23 will light up automatically after 4320 operating hours. To change the filter, proceed as follows:
Before cleaning, always ensure that the mains plug of the air purifier has been properly disconnected.
Regular cleaning of the filter 8 (once a month) is required to ensure hygienic and fault-free operation. Clean the outside of the filter with the brush attachment of a vacuum cleaner or a dry cloth.
NOTE
The three-layered filter should be changed after 4320 operating hours (see "Replacing the filter" section). The three-layered filter cannot be washed.
If you wish to change the filter at specific personal intervals (e.g. every 6 months), there is a sticker on the upper edge of the filter on which a date can be entered.
Clean the housing of the air purifier with a slightly damp cloth (water or a mild cleaning solution). Do not use solvents, other aggressive cleaning/scrubbing agents or alcohol, as these could damage the surface.
Regular cleaning of the dust sensor and its associated channel (once a month) is required to ensure faultfree operation. To do this, open the sensor flap 5 on the side of the device. Use a dry cotton bud to remove coarse dust from the open channel. For even better cleaning results, you can now also run the device at the highest setting to clear the loose dust. Close the sensor flap once cleaning is complete.
NOTE
Please note that using the device in a very dirty environment (such as a workshop with large amounts of dust) can cause excessive soiling of the sensor. As this contamination can cause incorrect measurements, clean the sensor more frequently in these environments.
If you do not plan to use the device for a long period of time, we recommend that you clean it and store it in the original packaging in a dry environment, ensuring it is not weighed down by additional items.
