5. The most important questions and answers about the air purifier comparison

5.1. How long should an air purifier run?

How long the device runs every day depends on the intended use.

In fact, it's hard to make a straight recommendation. The running time of the air purifier depends on the use. A high odor pollution, for example in the case of smokers, can make it necessary to use the air purifier for up to 10 hours a day. The same applies if the pets have an extreme smell, for example on rainy days.

Air purifiers with a timer function are ideal. In this way, the device can work independently and also switches itself off at night, which also reduces the power load.

In households where an air purifier is used in the event of an allergy, a short running time of 2-3 hours is often sufficient. It is best to use the air purifier during the "allergy times".

Tip: When buying an air purifier from a test, always pay attention to the information on power consumption. The lower the wattage, the cheaper the air cleaner is in terms of consumption.

5.2. Where can I buy an air purifier cheaply?

Air purifiers are available online and in specialist shops.

If you want to buy an air purifier test winner, an air purifier test is always a good way to find out about the various criteria, but also about differences in quality and equipment. Buying an air purifier online is almost always cheaper than buying it locally.

The air purifier ball is of course particularly cheap. It is only designed for rooms of up to 50 m², but this is usually sufficient. In addition, the ball impresses with its chic and, above all, mostly inconspicuous design, so that it is hardly noticeable in small rooms and can do its work quietly.

If a small air purifier is sufficient, the balls are good recommendations and are often available as an air purifier with water, which also means that the room is not humidified - often a blessing for people with house dust allergies.

5.3. Which manufacturers are known?

The following manufacturers are particularly often represented in an air purifier test, and they have been able to convince over the years with their good quality, but mostly also the right price-performance ratio:

  • Philips
  • Comedes
  • Beurer
  • Dyson

Dyson air purifiers are best known for their unusually chic design and, despite their size, add value to almost any room! If looks are important to you in your new air purifier, you should look around for the (albeit expensive) Dyson models.

5.4. Can you build an air purifier yourself?

Building an air purifier yourself is actually possible. Countless instructions can be found on the Internet.

You just have to note that not only is a little manual skill important, but electricity must also be used. If you have any doubts here, you should rather use a real device from an ionizer test. The air purifier balls are also particularly cheap alternatives, so that from a financial point of view doing it yourself is hardly worthwhile.

5.5. How healthy are air purifiers?

Daily ventilation is sufficient if the air pollution is low.

In an ionizer test, it is often suggested that air purifiers are downright indispensable. Air purifiers for allergy sufferers or especially as a combination device with air humidifier are absolutely recommended in every household if you do not want to endanger your health. However, this is only partially true.

It is true that people with health problems (asthma, allergy sufferers) or even in apartments with a high level of pollution (cigarette smoke, exhaust gases) are less exposed to the use of a good air purifier, but this is often unimportant for healthy people.

If there is little or no pollution from the environment and the residents are healthy, it is usually sufficient to ventilate the apartment daily (several times) to let the contaminated particles (and smells) outside and clean air into the apartment. Air purifiers are healthy, but not necessary for everyone.

5.6. How often does the air cleaner have to change the filter?

Many devices indicate when it is time to change the filter. As a rule of thumb, however, there is a filter every six months should be replaced.

But before you buy, you should find out which ones running costs for the air purifier attack.

The cost of a replacement filter varies depending on the make and model, as well as the size of the room. Replacement filters for air purifiers for smaller rooms usually cost 20 euros upwards, Replacement filters for larger rooms cost 40 euros and up.
