Some of the most common causes include:

• Colds and the flu. These are the most common causes of nasal congestion. The viruses that cause these infections can irritate and swell the lining of the nose, making it difficult to breathe through.
• Allergies. Allergies to pollen, dust, pet dander, and other allergens can also cause nasal congestion. When you come into contact with an allergen, your body releases histamine, which causes inflammation and swelling in the nose.
• Sinusitis. Sinusitis is an infection of the sinuses. The sinuses are air-filled cavities in the bones of your face. When these cavities become infected, they can swell and block the nasal passages.

When you use the inhaler, the eucalyptus and peppermint oils are vaporised and inhaled into the nose. The oils then travel to the nasal passages and begin to work their decongestant and soothing effects. Within a few minutes, you should start to feel relief from your congestion.

Here are the instructions on how to use the Numark nasal inhaler:

• Remove the cap from the inhaler
• Insert the tip of the inhaler into one nostril and close the other nostril with your finger
• Inhale deeply through your nose
• Repeat steps 2 and 3 in the other nostril
• Replace the cap on the inhaler

You can use the inhaler up to 3 times a day, as needed. If your symptoms do not improve after using the inhaler for 7 days, talk to your doctor.

The inhaler is suitable for adults and children aged 6 and over. However, there are some important things to keep in mind when using this medicine:

• Do not use the inhaler if you are allergic to any of the ingredients
• Do not use the inhaler if you have a history of nasal bleeding
• Do not use the inhaler if you are pregnant or breastfeeding
• Keep the inhaler out of the reach of children

It is also important to note that the Numark Nasal Inhaler is not a cure for a cold or other respiratory infection. It is simply a way to relieve the symptoms of congestion. If you are experiencing severe congestion or other symptoms, it is important to see a medical professional.

The Numark Nasal Inhaler clears the nasal passages by using the decongestant properties of eucalyptus oil. Eucalyptus oil works by constricting the blood vessels in the nose, which reduces the swelling and inflammation that can cause congestion. This allows the nasal passages to open up and allows for easier breathing.

The peppermint oil in the inhaler also helps to relieve congestion and soothe a sore throat. Peppermint oil has a cooling effect that can help to numb the pain and inflammation in the nose and throat.

Here are some alternative solutions for clearing nasal passages:

• Drink plenty of fluids. This will help to thin mucus and make it easier to cough up.
• Use a humidifier or take a hot shower. This will help to moisten the air and loosen mucus.
• Use saline nasal spray. This can help to flush out mucus and debris from the nasal passages.
• Get plenty of rest. This will help your body to fight off infection and heal.
