A smoke allergy can cause various symptoms, such as coughing, breathing difficulties and congestion. Fortunately, many home remedies can ease symptoms, from simply drinking more water to eating spicy foods. 

One of the most effective solutions is an air purifier, which can convert unhealthy, smoke-filled air into cleaner, more breathable air.

Whether from exhaust fumes or second-hand smoke, we all know what breathing suddenly in a waft of smoke is like. It’s never pleasant, yet the experience can be even more problematic for people with a smoke allergy. 

You’ve come to the right place if you’re concerned about this. 

Firstly, you’ll find a bumper guide on how to deal with the symptoms, with tips including breathing exercises and applying a warm compress. Next, we’ll look at the types of smoke that can cause allergy symptoms. 

Finally, we’ll look at the importance of using an air purifier to combat the problem and recommend the best devices.

11 Tips to tackle smoke allergy symptoms right now

Scroll down a bit to discover which types of smoke might be causing your allergies to flare up, or keep reading for tips about tackling the symptoms. 

Tip 1: Use a humidifier 

Using a humidifier is one of the most effective ways to increase moisture levels in your home and therefore improve breathing, according to Dr. Kathrin Nicolacakis.


Be sure to change the water in your humidifier daily because mold and bacteria can quickly grow in standing water.

A study from Harvard reports that humid air can help to cleanse the upper respiratory tract (including the nose, mouth and sinuses), making breathing more comfortable. 

Tip 2: Use eye drops daily 

Applying one drop twice daily is generally recommended, although dosage can vary according to your response and medical condition.


Eye drops beyond the prescribed period can cause more irritation, so avoid using them for too long. 

Eye drops are particularly effective for relieving allergy-related burning and stinging eyes, according to Dr. Liji Thomas. Many contain an antihistamine, meaning they can block a substance called histamine — the chemical responsible for several allergy systems. 

Tip 3: Use a neti pot 

A neti pot will thin mucus and flush it out of your system, easing congestion. You can buy the pots in pharmacies and online. 

Here is what you need to do:

  1. Fill the pot with the saline solution.
  2. Tilt your head over a sink and place the spout into one nostril, then gently pour the solution into that nostril. The liquid will flow out through the other nostril. 
  3. Refill the pot and repeat the process on the other nostril.

Use distilled, sterile, or boiled and cooled tap water. Regular tap water contains bacteria and other harmful organisms that can remain in your nasal passages.

According to a report published in American Family Physician, saline (or saltwater) nasal irrigation can effectively treat people with upper respiratory conditions, including allergic rhinitis. 

Tip 4: Breathing exercises 

If you’re unfamiliar with pranayama, don’t worry; any slow, deep breathing exercises (especially in a warm environment) can expand your lung capacity. Try this:

  1. Sit or lie down and place your hands on your abdomen
  2. Breathe in through your nose slowly, feeling your stomach expanding
  3. Hold your breath for a few seconds
  4. Breathe slowly through your mouth

It’s a good idea to practice breathing exercises when you’re not gasping and feel at ease. This means you can turn to them as and when needed.

Breathing exercises, particularly a yogic form called pranayama, can help to relax your airways and therefore ease wheezing, according to the Cleveland Clinic

Tip 5: Drink water 

This is simple, but it’s true — just drinking more water can ease a hoarse throat. A raspy, breathy or strained voice characterizes Hoarseness. 


Drink 64 ounces (approx. 2 liters) of water daily. Alcoholic and caffeinated drinks can dry out your throat. If you drink one cup of coffee, add an extra cup of water etc. 

According to an article published in the University of Texas Southwestern Medical Center, keeping hydrated helps your body produce more mucus, which means your vocal cords stay lubricated. A

Tip 6: Apply a warm compress 

While staying hydrated and drinking water above can relieve headaches, applying a warm compress to your face can also work as the heat helps to relax tense muscles. 


Taking a warm shower or bath may also have a similarly soothing effect.

A warm, wet washcloth is one of the most common methods and The American College of Allergy, Asthma, and Immunology recommends applying it several times a day. 

Tip 7: Eat chilli 

Chilli can help reduce a runny nose, but other spicy foods will also do the trick. Is anyone up for a curry tonight? 


Spicy foods aren’t for everyone, so steam inhalation via a warm bath or using a neti pot, as previously mentioned, can also help.

Chilli contains a chemical compound called capsaicin. This has anti-inflammatory properties and can numb nerve endings in the nose. A study published in 2016 found that capsaicin could ease non-allergic rhinitis.  

Tip 8: Drink ginger tea

Try eating some crystallized ginger instead of a throat lozenge. As ginger is also a muscle relaxant, it may help loosen a tight chest.


If you are not a fan of ginger, any other hot drink will do the trick. A study published in the Rhinology Journal discovered that hot fluids might decrease pain areas in the brain. Hot, sweet drinks, such as those with honey (which also has anti-inflammatory and antioxidant properties) are the most effective.

Ginger is a well-known aid for nausea, but it also has anti-inflammatory properties and can ease coughing. A 2016 study found that ginger can suppress coughing. 

Tip 9: Eat Fruit

Vitamin C is a natural antihistamine and antioxidant found in citrus fruits like oranges and vegetables such as broccoli. 


The recommended daily allowance (RDA) is 90 mg for men and 75 mg for women. For those with allergic rhinitis, this can be increased to 200 mg (but no more, as this can create side effects).

A study published in the Journal of International Medical Research found that a high intravenous dose of vitamin C helped to reduce allergy-related symptoms, such as sneezing.

Tip 10: Get an Air Purifier

If you’re wondering what air purifiers actually do… They use fans and filters to draw in dirty air before pushing clean, healthier air out.  

A 2020 study found that they help reduce indoor allergens’ concentration and are especially beneficial for people with allergic rhinitis. 

Making your own DIY air filter is one option, but if you’re thinking of buying, look no further. We’ve tested many purifiers at HouseFresh, including ones for wildfire smoke, cigarette smoke, cigar smoke and the best budget devices.

Common types of smoke that cause allergy symptoms 

Many types of smoke exist, including weed zand incense, but let’s look at three major types that can cause allergy symptoms.

🔥 Wildfire smoke 

According to the CDC, wildfire smoke can cause lung irritation and inflammation and affect the immune system. It could also make people more prone to lung infections, including the virus that causes COVID-19. 

Yet, wildfire smoke also causes allergy symptoms like a runny nose, coughing and difficulty breathing.  

Why is it so problematic? 

Well, it’s primarily due to particle matter and gaseous pollutants — two key components of wildfire smoke. A mix of liquid droplets and solids, particulate matter can remain suspended for hours and even days in polluted air. Because the particles are so tiny, they can enter your lungs, throat and nose. 

Gaseous pollutants are invisible, toxic gases in wildfire smoke and can seriously impact allergies. The various gasses include carbon monoxide and volatile organic compounds (VOCs), including formaldehyde, benzene and nitrogen oxides. 

🚬 Cigarette smoke 

While cigarette smoke isn’t considered an allergen (such as pollen), it’s most certainly an irritant and can cause allergy-like symptoms like coughing and sneezing. 

However, the various toxic ingredients and chemicals within the smoke (over 7,000 substances) trigger symptoms rather than the smoke itself. 

The harmful chemicals in cigarette smoke can be especially problematic for people with allergic rhinitis as they may be more sensitive to this type of smoke than others. 

This is because cigarette smoke can irritate the nasal passages and cause the mucus lining in the nose to thin. The mucus lining may already be compromised for people suffering from allergic rhinitis, meaning other irritants can quickly enter their body.

🚗 Air pollution

The World Health Organization (WHO) has found that 9 out of 10 people worldwide breathe polluted air. 

The continuing growth of industrialization means that every single day, people are breathing harmful chemicals such as nitrogen dioxide and sulfur dioxide from diesel exhaust fumes and factory chimney emissions. 

This has led to a rise in allergies caused by air pollution. People with underlying allergies, such as pollen, are especially at risk and may require medical intervention. Furthermore, air pollution can also cause allergic rhinitis. 

If you’re particularly concerned about air quality in your city or state, you can check it regularly using Air Now.
