Comedes Air Purifier - Proven Good

With more than 20 years of experience, air purifiers and dehumidifiers are the passion of the German supplier Comedes. The passion for air purifiers and dehumidifiers has been confirmed in the past by various test reports. In the air purifier test of the Comedes Lavaero 900 by Technik Zuhause (issue 06/2018) or in the dehumidifier test of the Demecto 30 by Hausgeräte-Test (issue 09/2018). Whether particles, pollen, mold or humidity, Comedes has the right device to combat airborne pollutants, allergens and mold spores.

Special features of Comedes air purifiers

Air purifiers with ionizers

What is meant by clustering in the air?
. Charged ion particles are a component of air. Üblicherweise these are produced by natural radiation or also by weather events such as thunderstorms and movements of the air. Since the ions stimulate particles in the air to form clusters, they are responsible for a natural cleaning effect. In this process, negatively charged ions adhere to dust particles suspended in the air. Subsequently, other dust particles from the air can combine to form a larger cluster. "similar to how, for example, statically charged foils "stick" together. These dust clusters can be filtered out more easily by air cleaners. For this reason, most Comedes air purifiers have in addition to a HEPA or activated carbon filter ütz;ber an ionizer.

Will the ionizers of Comedes air purifiers emit ozone?
Comedes air purifiers work mainly on the principle of clustering. For this purpose, only a low amount of ions is emitted without producing ozone. The air in a room with an area of about 20m contains hardly more ions than the air outside during the use of the ionizer. All Comedes air purifiers thus comply with IEC standard 60335.2.65.
Air purifiers that produce ozone are granted the advantage of eliminating odors efficiently. This is based on the fact that the ozone also migrates into walls, furniture and ceilings, reducing odor sources there. However, the associated harmful ozone pollution in the living space and the risk of the formation of other harmful degradation products, such as formaldehyde, are the reason why Comedes does not offer air purifiers based on ozone technology.

Automatic operation with PM 2.5 sensor measurement technology

The PM2.5 sensor detects the number of particles in the room air. Comedes air purifiers additionally üve LEDs, which qualitatively indicate the measured concentration of particles in the ambient air. Some devices offer additional displays that specifically show the quantitative particle concentration.

How do optical particle sensors work?

Optical particle sensors work based on the reflection of light off particles in the air. Dust particles in the air reflect incoming sunlight. The PM2.5 sensor recreates this principle by using an infrared LED light source. This is aligned with the air intake of the sensor chamber through which the ambient air is passed. A lens and diode are mounted at right angles to the infrared beam. As the concentration of particles in the air increases, the amount of scattered light entering the photodiode through the lens increases. The thus determined contamination of the air is used by the air purifiers to adjust the cleaning effect to the prevailing air conditions and thus helps to reduce the noise level and electricity costs.

Timer

The Comedes room air purifiers have übergübergreifend über a timer function. The timer is used to set the operating time of the device üt. Times between 1 and 12 or 24 hours can be preselected in the menu. After the time has elapsed, the device switches off independently.

Night/Sleep mode

To keep the noise level as low as possible at night, the sleep mode allows the volume of Comedes air purifiers to be reduced to a minimum. In addition to operating at the lowest noise level, all displays are dimmed or switched off so that they do not disturb the noise or light of the air purifier in the bedroom or children's room. By using the timer can also be ensured that the fan of the air purifier turns itself off after a certain time.
