What is Asthma?

The medical definition of asthma is a reversible narrowing of the airways which can occur as a result of an asthma attack

It is characterized by wheezing, chest tightness, coughing, and shortness of breath. Once considered an adult-onset disease, it is now known that asthma can occur at any age.

As winter approaches, you might be thinking of purchasing a humidifier for yourself or your loved ones. But are you really choosing the best one for your specific needs? Learn how to select the right type of humidifiers for asthma in this easy-to-read buying guide.

Before purchasing, consider the various features you might want to be included in your device to get the most out of your purchase.


HUMIDITY CONTROL is a process of maintaining humidity levels to ensure proper moisture, and it is especially important for buildings with wooden furniture. The cost of the system depends on the size of the building and the type of humidifiers used. The most cost-effective way to maintain a proper humidity level in a home is to install a humidifiers directly in the bedroom or living room.

Type of Mist

The mist is a very good way to help your allergies and asthma. If you use a portable unit or a warm air furnace, be sure to leave it on all day during the winter months. To keep the moisture level high enough in the air of your home throughout fall and winter, one study suggests keeping a mist at that 25 millimeters per hour mark. Regardless of whether you have allergies or not, some research has even suggested that using a humidifiers can even help you With asthma.


To find the best humidifiers for your needs, it is important to look at the size of your space as well as its usage. If you need a room or space larger than two thousand square feet, make sure the humidifier is about 50% higher capacity than your area. Another consideration is how much time and money you want to spend on cleaning and maintenance. Evaporative models require more frequent water changes and mineral buildup that can clog parts and ruin motors and filters, and even cloud the humidity.

If you plan to sleep or live in a stationary environment, a large will likely work just fine as you won’t be needing to haul it around.


There are quite a few things to look for in order to find the best humidifier. A good humidifier for asthmatics should also be easy to install, use and maintain. It should be designed in a way that makes it easy to refill with water, maintain, and clean. It is also crucial that the humidifier releases no harmful bacteria into the air.

Coverage Area

Consider the size of the area it can cover when choosing your device. Large humidifiers are often able to cover over 1,000 square feet; personal humidifiers usually cover 25 square feet. Humidifiers don’t usually have a water level indicator to let you know when you need to refill them. If your humidifier doesn’t have an automatic shutoff feature, you should remember to refill it before it runs out of water or overflows.

Are you going to be using the device in your bedroom? Some people prefer to place their humidifiers in another room so they can sleep comfortably without being disturbed by noise.

Tank Capacity

The tank capacity in humidifiers tells you how many hours of operation time will last before needing to be refilled. The bigger the tank, the less work it is on your part. Think about what you plan to use the humidifier for. If you only want it for occasional use in your room, then a small model is just fine. However, if you have a large room that needs more humidity control for asthma sufferers throughout the year, get a larger one. You'll need to look for something that will last you a full day of continuous use. For this, you will need to check the running time on the humidifier tank.
