Indoor air is often bad. Outgassing from furniture, cleaning agents, cooking or candles drive up the fine dust and VOC concentration. Open the window is essential for the supply of oxygen, but depending on the living situation (wood stoves, street, pollen), the situation even worsens after ventilation. A remedy creates Air purifiers that remove pollutants, allergens, odors, bacteria, viruses and sometimes dust fishes out of the room air.

Filter quality is crucial

The most important component of an air purifier is the filter. Good devices rely on them HEPA technology. HEPA stands for Hugh Eefficient Particulate Air (filter), translated as “highly efficient particle filter”. HEPA filters are available in different performance classes. A good overview of this and other technical terms is provided by the website Luftreinigungdepot.de. Some models also use ionizers and UV lamps.

We can only test in practice and not under laboratory conditions. We used that as a reference air quality meter Airthings View Plus (Test on connect.de).

All devices have one thing in common: They log the filter life and get in touch when it’s time to replace it (usually after a year). Unfortunately, the acquisition costs are not enough for an air purifier, and the replacement filters are quite expensive, depending on the model. Nevertheless, you should never exceed the usage time, otherwise the cleaning performance will suffer.
