Cleaning an air purifier regularly ensures that the device continues to work efficiently and lasts longer. It is a matter of a few minutes, provided you go about it the right way.
Switch off the device first and unplug it
Before you start cleaning, turn off the air purifier and unplug it from the power outlet. This not only prevents an electrical risk, but it also prevents you from accidentally pushing dust and dirt deeper into the device while the fan is still running.
Step-by-step cleaning
- Exterior: wipe down the housing with a slightly damp, soft cloth. Do not use harsh cleaning agents or solvents, as these can damage the plastic.
- Intake grille: remove loose dust and hair with a soft brush or the brush attachment of the vacuum cleaner on a low setting.
- Pre-filter: with most air purifiers, including the AirPure Plus PA244, the pre-filter is separately removable. Shake it out, vacuum it, or rinse it with lukewarm water if the manufacturer allows it. Let it dry completely before replacing it.
- HEPA filter: this component can be carefully shaken or vacuumed out, but do not wash it. Water damages the fine fiber structure. You can read more about this in our article on cleaning a HEPA filter.
- Sensor (if present): gently wipe the air quality sensor clean with a dry cotton swab, as dust can affect the measurement.
How often cleaning is required
You can safely wipe down the intake grille and the exterior every two to four weeks. It is best to check the pre-filter monthly and clean it as soon as you see dust accumulation. Instead of continuing to clean the HEPA filter itself, you should replace it, usually after six to twelve months of use, depending on the air quality in your home and the number of operating hours.
Common mistakes
- Getting the HEPA filter wet or holding it under the tap.
- Cleaning while the device is still on or plugged in.
- Replacing a damp filter before it is completely dry; this can cause mold growth.
- Using harsh cleaning agents or alcohol on the housing.
Why this maintenance pays off
A clean grille and filter ensure better airflow, less noise, and an air purifier that actually achieves its specified capacity, such as the CADR of 260 m3/h for the AirPure Plus PA244. A neglected device has to work harder for the same result, which also increases power consumption.
Our advice: incorporate the cleaning of the grille and pre-filter into your regular monthly routine, and track the replacement of the HEPA filter separately. A suitable HEPA13 replacement filter for the AirPure Plus PA244 is immediately available so that you are never without full filtration for long.
Adjust the schedule to your situation
The frequencies mentioned above are a good starting point for an average household, but they are not set in stone. If you have pets, smoke in the house, live on a busy road, or keep the device on a high setting continuously, then more frequent cleaning and earlier replacement are advisable. If the air purifier mainly runs at night on a low setting in a quiet bedroom, you can often get by with the intervals mentioned above. So, don't just look at the calendar, but also at the actual dust and pollution you see during your inspection.
