How To Choose The Best Humidifiers For Sinus Problems?
Room Dimensions
- This element is paramount when choosing the right humidifier and it must be considered first. Room dimensions are key to decide the tank capacity and humidification performance of a humidifier.
- As a basic rule of thumb, the larger the room, the bigger the tank capacity and the more powerful humidification the machine.
- Most humidifier manufacturers indicate the recommended room size for their products. Your task is to measure the room area you intend to place it in. Multiply the width and length of this room (whether in feet or meters).
- If the suggested room size on the humidifier label is in m3. Just multiply the room area with its ceiling height. For example, a room that has 10’ wide, 15’ long, and 10’ high has a volume of 10x15x10 = 1500 m3.
- Don’t go for an overly big humidifier because too much moisture in a room will lead to the risks of mold and mildew growth.
Water Tank Capacity
- It is equivalent to the amount of water the humidifier’s tank can accommodate.
- The smaller the device, the smaller the water tank, leading to a smaller amount of water it can hold. Water tank capacity is also an indirect feature affecting the runtime of your machine.
- While the room dimensions partly impact on the choice of water tank capacity, it mostly depends on your preference.
- Do you like to refill water every day or want something that can run continuously within 2-3 days before running out of water?
- You might think most people love going for the second option but in fact, the majority prefer the first one because larger water tank capacity means the higher chance for mold growth. If you still a big one, consider an additional filtration system to trap such mold and mildew.
- Remember, your goal is to increase the moisture and humidity in the air, but that “moisture and humidity” must be clean, not dirty.
Types Of Mist
- For sinus problems, the humidifiers feature two mist options: cool mist and warm mist. It is varied among different models. Some only produce cool mist while others feature two.
- Cool mist humidifiers run more quietly and are much cheaper while the warm mist provides more moisture. One notable thing that makes warm mist humidifiers superior to its counterpart is as producing steam, they can kill bacteria and mold in the air.
Other Features
Runtime
- For the best results in soothing the sinus problems, humidifiers should be run day and night or whenever you’re at home.
- However, if you are a clumsy person who usually forgets to turn off the machine whenever going out, considering a model equipped with appropriate runtime settings is essential. It is not just a convenient feature but also for your safety.
- Think about it, what would happen if your humidifier runs out of the water and it can’t automatically shut down?
- Most devices nowadays are programmed to give you 2, 4, 6, 8, or up to 12 hours of constant runtime. During this operating period of time, just make sure its water tank isn’t empty.
Light indicator & auto-shutoff function
- These two features are for souped-up safety.
- When the tank runs out of the water, an LED light indicator will change its color to tell you it’s time to refill water. The auto-shutoff function is activated after a certain amount of time if detecting no water is added to its tank.
