Air circulation
The amount of air that the air cooler can pass through itself in an hour.
This parameter depends on the power and the overall level of the device, but there is no strict dependence here: models with the same effective power may differ in air circulation speed. In such cases, it is worth proceeding from the fact that a higher speed contributes to more uniform mixing of air and reduces the time required to create a given microclimate; on the other hand, higher-performance devices use more power, are larger and/or cost more.
Water tank volume
The volume of the water tank installed in the air cooler. A large capacity allows you to work longer without adding water, but it affects the dimensions and weight of the device. It should be borne in mind that the cooler the water, the greater the cooling effect and frequent water changes are even beneficial. Also, do not forget that pathogenic bacteria can grow in water if there is water left in the tank and the device is not used for a long time.
Ionizer
A device for saturating the air with negatively charged ions. It is believed that the presence of such ions in the air has a beneficial effect on health and well-being, and also creates a feeling of freshness. In addition,
ionization helps to reduce the amount of flying dust — it settles faster on various surfaces.
Noise level
The maximum noise level generated by the air cooler during operation. Most of these devices are used in residential areas, so this parameter should be treated carefully. According to sanitary standards, constant noise in such rooms should not exceed 40 dB (quiet conversation) during the day and 30 dB (wall clock ticking) at night. More detailed comparison tables and recommendations can be found in special sources. It is also worth mentioning that the noise level is indicated for the maximum operating speed, so the noise level will be significantly lower in reduced mode.
