This unit does not use a filter, unlike most humidifiers. However, we do not recommend using ordinary tap water, as its high mineral content can cause the unit to release white dust. The unit also has an automatic shut-off feature that activates when the tank is empty to prevent damage. However, several customers have complained about the difficulty of cleaning this unit, so you may want to keep this in mind when shopping.

  • How can it help your cough?


How can it help your cough?

When you have a cough, your throat and nasal passages usually dry out. Most of the time, this is because the required humidity is higher than the current humidity in the room, which causes the cough. Here’s how a humidifier can help relieve cold symptoms:
They increase the humidity of the air and thus allow better breathing.
They moisten dry and sore throats.
Reduce inflammation of the nasal passages.
Relieve sinus congestion.
Features to consider when choosing a cough humidifier
Not all humidifiers are created equal, which means that you need to consider different things when buying different types of humidifiers. If you are looking to buy the best humidifier for a nagging cough, here are the most important factors to consider.

Type of mist

Humidifiers are capable of producing either a warm or cool mist. Warm mist is refreshing and pleasant in winter, but cool mist is particularly soothing in summer. Humidifiers are most often used in colder periods, during flu and cold season, so it is always good to have a device with a warm mist. Keep in mind that if you intend to use a humidifier in a fairly large office, room or flat, chances are that the air particles will be at room temperature when they arrive at your home.

In addition, warm mist humidifiers contain a heating element, so it is not advisable to leave them running without you nearby, especially if you have small children or pets.

Water tank capacity

The water tank capacity of the device determines two different things. First, keep in mind that the larger the tank size, the more fog you can disperse into the atmosphere. If your device has a large tank, it can humidify a larger area for a longer period of time. Also, a large tank means that you don’t need to refill it as often as with a smaller tank.

Fogging time

Fogging time is the length of time a humidifier is able to fog before the tank dries out. A humidifier usually comes with several settings, so if a product is advertised as having a fogging time of up to 20 hours, it may only be on the lowest setting. If you use it on a high setting, the tank may empty in just 12 hours. If you intend to use your device at night, make sure you choose a model with a misting time of at least 10 hours. This will ensure that it is still working when you wake up.

Coverage area

Each humidifier is capable of covering a specific maximum area. While the smaller units are designed for office use, the larger ones (such as oven humidifiers) can humidify a whole house. Bedroom humidifiers fall somewhere in between.

Noise level

All humidifiers make some noise, even though they are supposed to be quiet. If you have a bedroom model, it is essential that it is very quiet so that it does not disturb your sleep. In general, the larger the appliance, the louder it is. Hot steam and evaporative models also tend to be louder. If you are an extremely noise-sensitive person, look for models that operate quietly, such as the OPOLA Digital Humidifier and the Vicks Warm Steam Humidifier.

Essential oil diffuser

Essential oils are extremely popular at the moment. As well as smelling wonderful, they help to relax and calm the emotions after a stressful day. If you are interested in essential oils, buy a model with an essential oil diffuser option. This will save you space and money as you won’t need two large units in your room.

Additional features

Some of the things you should check are whether the unit has an automatic shut-off, a warranty, a timer and whether it uses a filter.

The automatic shut-off means that you can leave the unit running all night, even if your children are sleeping next door, without fear of the unit overheating. A long warranty is also essential, as humidifiers, like any other electronic device, tend to break from time to time, so it’s always good to have some sort of guarantee. A timer, as well as intensity levels, will allow you to control the unit more effectively. Models without filters are easier to maintain as they do not require extra expense, while humidifiers with filters make the water cleaner and extend the life of the unit. However, bear in mind that adding these sophisticated features may mean you have to pay more for the unit.
