If you are suffering from asthma allergies or other respiratory illnesses the air and air dryness of the air in your environment will make your condition more acute. Dust is the first factor that can cause allergies. To eliminate the dust problem it's best to keep the air around you wet. To do this you need to air humidifier. You do not need to worry about air dryness using the air humidifier. Of course it should be noted that the same amount of humidity that the problem produces the excessive amount of moisture also has its own problems. When the humidity of the air is increased it creates a good environment for the growth and replication of germs and fungi. The humidity should be between 40% and 50%. You can use a moisture meter to measure air humidity. Some air humidifier devices also have a moisture meter next to them but it is better to use a separate moisture meter to make sure. Air humidifiers can partially clean the air and clear the air from pollutants. To do this you need to have an air humidifier that in addition to increasing humidity also has the ability to clean the air. In these air humidifier there is often a filter for this task. These filters are very important because they clean the air and keep them clean regularly. Having a negative ion is an option that allows the intake device to act as an air purifier. You can also read more about negative ion performance in the "Ion Negative" article. The next tip is how to clean the device filter. It's best to use the product manual and articles in this area for the correct way. Apart from the filter the machine itself needs to be cleaned repeatedly. Failure to properly clean this device can affect its benefits. Use the refined water for the device as much as possible. The water that does not contain much salts will increase the useful life of the device and reduce the possibility of bacterial growth there too. The water that is soluble will be removed in the form of a white dust when it comes out of the machine. If you have any allergies be sure to consult your doctor about how and when to use the emulsion. The humidity level varies from one disease to another.
