If you have allergies and happen to live in a place where the weather is changing greatly, you may feel the allergic symptoms more strongly. Fortunately, higher humidity air can help you breathe more smoothly and allay allergic symptoms, discomforts and medicine side effects.

In addition, the dust mites, the most important and common cause of allergies, can thrive on the house only when the humidity of the air is beyond certain minimum levels. So, maintaining a lower humidity in the air can prevent house dust and molds from thriving, which in turn can reduce the cause of allergies significantly and help to avoid asthma that is induced by perennial or severe allergies.

It’s very clear that humidify level has great impact on those who are suffering allergies. It not only can affect the treatment of allergies, but the development as well. But neither too low nor too high humidity levels are good for relieving allergies. Too low humidity can lead to great dryness in the air, which causes unhealthy discomforts, while too high humidity in the air is able to cause excessive dampness that encourages molds growth. So the key point is to maintain a proper humidity level.

What’s a proper humidity level? And how to maintain it?

Humidity, usually called the relative humidity, is expressed as a percentage to measure the amount of moisture in air. Theoretically, it can range from 0% to 100 %, or higher, but indoor humidity usually fluctuates between 20% and 70%.

Generally, how comfortable people feel is partially decided by the humidity. When the humidity is higher, people will feel warmer of the air at a specific temperature. But when the humidity is lower, people can feel cooler even at the same temperature. So it’s better for you to maintain the humidity level of your home higher than 30% in winters, which can help you feel warmer.

We know that high temperature between 75 ºC to 80 ºC and high humidity about 70% to 80% provide a wonderful condition for arthropods to thrive, such as bacteria and house mites. And eliminating these arthropods is almost impossible by manual cleaning. But it’s absolutely possible to reduce the quantity of house mites by adjusting the humidity levels. Usually, when the humidity level is below 50%, house dust mites are unable to thrive.

Thanks to modern humidifiers, maintaining a proper humidity level has become very easy. Typically, humidifiers include an integral gadget, usually a built-in hydrometer, to measure the humidity of the air. Just turn on your humidifier and regulate the setting between 40% and 48%, and then you can manage the balanced humidity levels in your home. Dust mites will be depressed substantially and you will feel more comfortable.

There are multiple types of humidifiers in the markets. Some can humidify the air of one room, while some can provide adequate humidification for several rooms. Most people prefer point-to-use humidifiers because they are often portable that does not require the installation on the air conditioning or duct system.

Among all humidifier types, perhaps, evaporative humidifiers are the most popular and common ones. This type generally is composed of a water tank, a wick and a filter and generates cool mist, so evaporative humidifiers are also known as cool mist humidifiers.

Noticeably, some humidifiers that do not require filters for running may build up minerals in the rooms, because the minerals or dusts that are present in the water can become airborne and sent into the air with mists. So these humidifiers, such as ultrasonic and impeller models, are not good choices for treating allergies.

Choosing an ideal humidifier is very critical to maintain the humidity levels easily, but the maintenance of your humidifier also plays a great role on the moisture of the air. In general, the water tank of a humidifier needs to be refilled and cleaned regularly. If your humidifier has a filter, you also need to replace it periodically to prevent molds and bacteria from growing.
