Air Purifiers for asthma

Almost 28 million people in the U.S. Suffer from asthma, according to Kenneth Mendez, president and CEO of the Asthma and Allergy Foundation of America (AAFA). He tells me that asthma can cause inflammation and swelling of the airways, resulting in shortness of breath, coughing, wheezing, and chest pain or tightness of the chest. Asthma symptoms can be triggered by a variety of allergens, ranging from dust and pet dander to seasonal pollen and mold spores. Can air purifiers—like our best overall, the Levoit EverestAir Smart Air Purifier—help manage asthma indoors? 

"Yes, allergists recommend air purifiers—but not specific brands—as a helpful tool for managing indoor air quality to remove common allergens, such as pollen or mold," Mendez says. "Allergic asthma is the most common type of asthma, so removing allergy triggers can also help prevent asthma episodes," he says.

That tracks with a 2018 study, which found that air purifiers improved the indoor air of patients with asthma. The Journal of Allergy and Clinical Immunology (JACI) found air purifiers were an effective tool in asthma management by reducing indoor allergens, and we consider the following to be the best air purifiers for asthma. 

How we chose the best air purifiers for asthma

We conducted extensive research, reached out to two allergy experts, and engaged in first-hand testing to compile this list of the best air purifiers for asthma. I don't suffer from this condition, but I do have smoking neighbors, and according to data from the Centers for Disease Control and Prevention (CDC), secondhand smoke is a typical asthma trigger since it contains gases and fine particles. So, I have a vested interest in finding the best air purifiers to combat secondhand and thirdhand smoke (that's the residual smoke that gets trapped in carpets, curtains, bedding, clothing, and on walls and floors). 

Every selection on this list has been thoroughly tested—sometimes for months, sometimes for years. Other factors in the selection process include peer recommendations, consumer reviews, and other criteria, including clean air delivery rate (CADR), air filter type, and user-friendliness.

The best air purifiers for asthma: Reviews & Recommendations

One thing to note: We at Popular Science pride ourselves on recommending the best products at the best price. However, asthma can be a life-threatening health issue, so the priority is to remove allergens from the air as quickly and efficiently as possible. While a small air purifier or a cheap air purifier may be a good air purifier in certain circumstances, it is unlikely to work as well as a larger model with a higher CADR. So our picks are more of an investment than the best budget lists. But an investment in your health is a wise investment.

Best overall: Levoit EverestAir Smart Air Purifier  Levoit air purifier on floor

  • Smartphone control
  • Voice commands
  • Wheels make it easy to move
  • Vent angles are adjustable
  • Reads PM1.0, PM 2.5, PM10
  • High CADR
  • Specs

  • Dimensions: 18.9 x 8.5 x 23.2 inches
  • Weight: 20 lbs
  • Recommended coverage area: 558 – 2,790 square feet
  • CADR: 360
  • Noise level: 24 – 56dB
  • We think the Levoit EverestAir is the best air purifier for asthma (and it's also one of the best air purifiers for smoke). It has a high CADR, excellent filtration system, and easy-to-operate controls. The air purifier is also sleek and stylish, and the slim design fits easily in tight spaces. The Levoit EverestAir also has wheels, making it easy to move from one room to the next. 

    The controls on top include both icons and text, and the display is easy to read. Selections include the power button, air info button, air quality indicator rings, clean air indicator, and particular matter indicator. The air info selection reads various types of particular matter: PM1.0 (like fine dust and microtoxins), PM 2.5 (like dust, pet dander, and smoke), and PM10 (pollen, ash, and airborne allergens). The display also includes settings for sleep, auto, turbo, speed, angle, and timer. Air quality indicator rings on the display turn colors: blue for very good, green for good, orange for moderate, and red for bad. There are three fan speeds, as well as a sleep mode and a turbo mode. In addition to the manual controls on top, the air purifier can be controlled via smartphone after downloading the app, and by voice control.

    I really like the 3-stage filtration system, which consists of a H13 True HEPA filter to capture small particles, like dust, smoke, pollen, and pet dander. The activated carbon filter absorbs fumes, odors, and smoke. The washable pre-filter is designed to trap large particles like dust, lint, pet fur, and hair. The washable pre-filter actually helps to extend the HEPA filter's lifespan. The pre-filter should be cleaned every 2 to 4 weeks, and the HEPA/activated filter pack should be replaced every 12 to 15 months. The magnetic front cover snaps on and comes off easily when it's time to change the filter pack. The vent is on the top of the air purifier as well. Another feature that impresses me is the ability to change the vent angle (45 degrees, 60 degrees, 75 degrees, or 90 degrees). 

    The CADR is 360, which is significantly higher than the average air purifier CADR of 200 range. 

    Best design: Alen BreatheSmart 75i Air Purifier    Alen Breathsmart 75i air purifier on the floor

    Terri Williams

    See It Pros
  • Choose from a variety of filter types
  • Swappable designer front panels
  • Advanced filter indicators
  • High CADR
  • Wheels make it easier to move
  • Specs

  • Dimensions: 27 x 18.5 x 11.5 inches
  • Weight: 27 lbs
  • Recommended coverage area: 1300 square feet
  • CADR: 350
  • Noise level: 25 – 49dBa
  • Alen makes air purifiers for small, medium, and large rooms. However, the Alen BreatheSmart 75i is our favorite because it's the most powerful model and can quickly purify the air in large rooms (1,400 sq ft every 30 minutes or 2,800 sq ft every hour). I'll admit that I'm partial to this air purifier because it was the first one I tested back in fall 2020 and tends to be the standard against which other air purifiers are measured. The only reason the Alen BreatheSmart 75i didn't take the top spot on this list is that it's several hundred dollars more expensive than the Levoit EverestAir above and has a comparable CADR. 

    However, the Alen BreathSmart has a nearly flawless design—which is why it's also one of the best smart air purifiers. The designer front panels are swappable. When I got the air purifier, I chose the graphite panel, and I later ordered the discontinued red panel. Other front panel color choices include white, weathered gray, maple, espresso, and rosewood. The magnetic front panels are a cosmetic feature; more importantly, I can choose from a variety of H13 HEPA filters. The Pure filter is best for dust and allergens, while the Fresh filter is designed for wildfire smoke and secondhand smoke, and the Odor filter neutralizes offensive smells.

    The display on top includes color rings to indicate real-time air quality: blue for very low levels of airborne particles, green for low levels, orange for medium levels, yellow for significant levels, and red for very significant levels of airborne particles detected. In addition to the power button, other selections on the control panel are for the ozone-safe ionizer (I always leave this off), timer, four fan speeds, and also a turbo mode, auto mode, and lock. 

    One feature in particular that I like is the replace filter indicator. Most air purifiers have this function. However, it only indicates when the filter actually needs to be replaced. The Alen BreatheSmart 75i has 3 different lights: one to let me know the filter is good, a second one to let me know when the filter is at the halfway mark, and then a third light when it's time to replace the filter. This helps me more effectively gauge my filter's lifespan so I won't be caught off guard. The typical filter life is 12 to 15 months. Perhaps the only negative I can find with this air purifier is that it's heavy. There is a handle on the back, and the air purifier does have wheels. However, it's still rather difficult to move around. 

    Best portable: Coway Airmega AP-1512HH Air Purifier coway air purifier on a carpeted floor

    Terri Williams

    See It Pros
  • Lightweight
  • Smartphone control
  • Voice control
  • Cons
  • Feels rather cheaply made compared to others on the list
  • Specs 

  • Dimensions: 18.3 x 9.6 x 16.8 inches
  • Weight: 12.3 lbs
  • Recommended coverage area: Up to 1,575 square feet
  • CADR: 221
  • Noise level: 24 – 53dB
  • Admittedly, many of the air purifiers on our list are quite powerful—and heavy enough that you won't want to move them more than you need to. However, the Coway Airmega AP-1522HH is an excellent choice if you need to easily transport your air purifier from one room to another. Keep in mind that an air purifier tends to work best in one room. It doesn't go around corners and under closed doors. So, it needs to be in the room that you're in for best results. 

    The filtration process includes a pre-filter (for large dust, dust mites, hair, and pet hair), True HEPA filter (for fine dust and pollen), and fresh starter deodorization filter (for VOCs, cigarette fumes, food smells, and pet odors). There are three speeds, in addition to a smart mode and an eco mode. The color-coded air indicators are blue for clean air, purplish-pink for polluted air, and red for highly polluted air. The display panel on the top also includes the selections for the on/off button, light on/off, Wi-Fi, and air quality.

    The CADR of 221 (for pollen) is pretty average and what you'd expect from a good, smaller, portable air purifier. However, this is a very popular air purifier among consumers, and many of our colleagues at other publications have rated it their best overall choice.  

    Best to heat and cool: Dyson Hot + Cold Formaldehyde Air Purifier  Dyson HotCold air purifier

    Terri Williams

    See It Pros
  • Produces warm or cool air
  • Removes formaldehyde
  • 10 speeds
  • Can control via smartphone
  • Voice control
  • Specs

  • Dimensions: 30 x 5 x 9.8 inches
  • Weight: 12.6 lbs
  • Recommended coverage area: N/A
  • CADR: N/A
  • Noise level: N/A
  • If you're like most people, your air not only needs to be purified but also cooled or heated as well. Sometimes, the temperature change isn't significant enough to warrant adjusting the HVAC thermostat. When I just need a little breeze or to slightly warm the air, the Dyson Hot + Cold Formaldehyde Air Purifier is perfect. It's not a budget-friendly air purifier, but considering it eliminates the need to purchase a separate fan and space heater (and eliminates the floor space required for all three appliances), it helps justify the price. 

    For those with asthma, the air purifier provides another bonus as well. It's designed to destroy formaldehyde, a gas that can be found in several household items, including carpets, mattresses, furniture, and even dryer sheets and air fresheners. A 2021 PLOS One review found a credible link between exposure to formaldehyde and asthma symptoms. However, the air purifier has an SCO filter that not only traps formaldehyde but also converts it into water and CO2—and, since the SCO filter self-regenerates, it doesn't have to be replaced.

    But that's not the only filter—there's also a 360 combi glass HEPA and carbon air purifier filter, which can remove gases, odors, dust, pollen, and other allergens. The HEPA/carbon filter should be replaced every 12 months. There are controls on the air purifier, along with a remote control, but the machine can also be controlled via smartphone or voice commands.

    Best splurge: IQ Air Atem X Smart Air Purifier IQ Air Atem air purifier

    Terri Williams

    See It Pros
  • Very high CADR
  • 8 fan speeds
  • Control via smartphone
  • Can be placed right up against the wall
  • Cons
  • An-arm-and-a-leg expensive
  • Specs

  • Dimensions: 10 x 27.1 x 27.1 inches
  • Weight: 28.7 lbs.
  • Recommended coverage area: 1,650 square feet
  • CADR: 422
  • Noise level: 26-55 dB
  • If you have $1,399 in your budget, the IQ Air Atem X Smart Air Purifier is the Rolls-Royce (I prefer sports cars, so it's like the Porsche) of air purifiers. The futuristic design is always a conversation starter, and most first-time guests at my home ask, "What is that?" as soon as they see it. Note: in the photo above, it's wedged between my sofa and armchair for a level of consistency among the photos since most of the other air purifiers are photographed up against a window. However, the air purifier is usually housed on one side of the kitchen island and cleans the air in the open-concept kitchen and living room setup.

    The minimalist air purifier has circular vents, and the direction of the vents can be adjusted (to flow left or right) as needed. The control panel is on the rear rim of the air purifier, although it can also be controlled via smartphone after downloading the app. The control panel includes the following buttons: power, smart mode (for automatic fan speed control). Light, and Wi-Fi. There are also air quality lights: green for good, yellow for moderate, orange for unhealthy for sensitive groups, red for unhealthy, purple for very unhealthy, and purple flashing for very hazardous.

    There are eight fan speeds, and I also appreciate that the filter replacement status has a yellow warning light when the filters need to be replaced soon and a red light when the filters actually need to be replaced. There are three circular filters in the air purifier. The air purifier is heavy, but it comes with an optional mobile base if you need to move it frequently. 

    Best for small spaces: Pure Enrichment PureZone Smart Air Purifier Pure Enrichment air purifier

    Terri Williams

    See It Pros
  • Smartphone controlled
  • Voice control
  • 5-stage filtration process
  • Specs

  • Dimensions:.1 x 11.1 x 21.7 inches
  • Weight: 11.5 pounds
  • Recommended coverage area: up to 1,050 square feet
  • CADR: 280 
  • Noise level: 27 – 54dB
  • The Pure Enrichment PureZone Smart Air Purifier has a space-saving design but still provides great filtration for a small room. In fact, it has a 5-stage purification process that includes a pre-filter (for dust, lint, pet hair, and pollen), antibacterial filter to inhibit bacterial growth, H13 Tue HEPA filter (for small allergens, tobacco and wildfire smoke, dander, and mold spores), activated charcoal filter (to absorb harmful gases, odors and smoke), and an antimicrobial UVC-light (which I don't use). The air purifier also has a higher-than-average CADR.

    The control panel displays the air quality rating and filter reset indicator. It also has icons for on/off, auto mode, four fan speeds, auto shut-off timer, sleep mode, and child lock. In addition to the controls on the top, the air purifier can also be controlled via smartphone after downloading the app and through voice commands. The air purifier does not have any type of handle or carrying strap, but weighing just 11.5 pounds, it's easy to pick up and carry from room to room. Overall, it's the best-value air purifying device we're featuring.

    These are some factors to remember to ensure your air purifier works to remove asthma triggers effectively and efficiently.

    Room size and CADR

    When selecting an air purifier, Kenneth Mendez recommends determining the size of the room where you'll be using it. "It's important to ensure the device can accommodate the size of the room it is being placed in, or else it will not be as effective," he says.

    Air purifiers have ratings that show the volume of air they can clean. Mendez says a useful way to determine this is by an air purifier's clean air delivery rate or CADR. "A CADR rating quantifies the effectiveness of an air purifier to remove smoke, dust, and pollen particles based on the size of the room," he says. If you purchase an air cleaner with a CADR rating too low for your room, Mendez warns that it will be ineffective.  

    Filter

    "HEPA, which stands for High-Efficiency Particulate Arrestance [or Air], is a high-performance filtration media designed to trap fine contaminants effectively," says Dr. John McKeon, CEO of Allergy Standards Ltd.—the international certification body that creates standards for products to be considered asthma and allergy friendly.

    "True HEPA filters can capture 99.97 percent of particles as small as 0.3 microns, including pollen, mold spores, dust mite allergen, and some pathogens, making them highly effective for individuals with allergies, asthma, or respiratory conditions," he says.

    McKeon notes that HEPA filters in air purifiers are often paired with activated carbon filters to capture both airborne particles and gaseous pollutants, including odors. "For smoke filtration or air pollution, look for models that combine true HEPA filters along with activated carbon filters to help reduce the burden of indoor contaminants," he advises.

    Smart  

    Most air purifiers have digital control panels. However, you may prefer the ability to control your air purifier from your phone. Some models can join your Wi-Fi network and have apps that can be downloaded and let you control the air purifier remotely. Voice control is another option that's available on air purifiers with smart-home features. In addition, a smart air purifier will allow you to use the auto feature, which can sense the room's air quality and automatically choose the best speed.

    Noise

    In my experience, after testing well over 50 air purifiers, they're all loud when on the highest setting. (At least the air purifiers that actually do what they're designed to do are loud on the highest setting.) Some may be a few decibels louder or quieter than competitors, but it's usually not a discernible difference.

    Portability

    Air purifiers can't clean your entire house (unless you get a whole-house air purifier). And unless you live in a completely open-concept home (with no walls—except for the bathroom), one air purifier can't clean your entire space. If you can only get one air purifier, you may need to transport it to whatever room you're in at the time. If you need to do this several times every day, portability will be a very important factor, so consider the weight and transport options of the air purifier.

    FAQs Q: Which is better for asthma, a humidifier or an air purifier?

    We posed this question to Kenneth Mendez since he's the president and CEO of the Asthma and Allergy Foundation of America. "Both air purifiers and humidifiers may offer benefits for people with asthma—it depends on the air quality and humidity level in your home," he tells me.

    An air purifier helps remove common allergens, while Mendez says controlling humidity inside your home can contribute to better indoor air quality and health. "Low humidity can cause your skin to dry out, as well as your eyes, nose, and lips," he warns. 

    Q: Are HEPA air purifiers for allergies and asthma effective?

    Mendez says air purifiers with HEPA filters can be an effective allergen reduction tool. "HEPA stands for High-Efficiency Particulate Air: These filters are media-based, meaning that they are physical filters, which capture particles as air passes through them, and HEPA filters are designed to filter out at least 99.7 percent of particles of 0.3 microns or larger diameter."  

    However, Mendez says HEPA filters won't be effective if they're not used properly. For example, if the seal around the filter is not tight enough, Mendez explains that the air might be able to bypass the filter. Also, filters should be changed when indicated since a dirty filter is not effective.   

    Q: How do air purifiers work?

    McKeon explains that air purifiers are designed to remove small particulate matter, a type of air pollution, from the air we breathe. "These small particles can vary in size and can irritate the lungs or trigger allergic reactions when inhaled," he says. "PM2.5 refers to particulate matter with a diameter of less than 2.5 microns, while PM0.1 represents ultrafine particles measuring under 0.1 microns." 

    McKeon says some larger particles are filtered through your nose hairs while smaller particles can penetrate deeper into the body. "Primary sources of particulate air pollution include cooking, automobile emissions, dust, household activities and products, fires or burning of coal and other materials." 

    Some air purifiers work by trapping particles and allergens like pollen or pet dander in their media-based filters. "Other air purifiers work by using electrostatic precipitation or ionizing technology to give particles an electrostatic charge which allows them to be removed from the air," McKeon says.

    But he warns that some air purifiers may produce ozone as a by-product. "Ozone can cause irritation and inflammation of the airways in healthy people, and it can cause more serious effects in people with asthma, so take care to choose devices that do not emit ozone above safety threshold values [0.05 ppm] indicated by the California Air Resources Board [CARB]," McKeon advises. 

    Final thoughts on the best air purifiers for asthma

    Contaminants in your indoor air quality can cause asthma flare-ups. Fortunately, there are air purifiers designed to remove allergens and remove asthma triggers—if you choose the right one. Factors to consider include a high CADR number and air transfer rate, as well as a HEPA filter—and preferably an active carbon filter as well. When used as instructed (which includes changing the filter as indicated), you can keep your home's air clean and healthy.

    Everything You Need To Know About Asthma-COPD Overlap Syndrome

    People who have symptoms of both asthma and chronic obstructive pulmonary disease (COPD) may have a condition known as asthma-COPD overlap syndrome (ACOS).

    Asthma is a chronic lung disease that causes reversible airway narrowing, inflammation in the airways, and mucus production. Some asthma symptoms are shortness of breath, tightening in the chest, and wheezing.

    Most people with asthma have exacerbations or flare-ups, which are times when their symptoms are worse than usual. There are also times when they have few or no symptoms.

    Emphysema and chronic bronchitis are the two main conditions that fall under the COPD umbrella. COPD is a progressive disease that can cause shortness of breath, chest tightening, mucus production, and an ongoing cough. People with COPD have regular symptoms and also experience flares.

    Asthma and COPD are the most commonly diagnosed chronic lung diseases. Both involve inflammation of the airways, obstruction of airflow, and other common symptoms. If you have symptoms of both of these conditions, you may have ACOS.

  • labored breathing
  • wheezing
  • wet or dry coughing
  • tightness in the chest
  • Symptoms can vary from day to day and typically include flare-ups. There are also key differences between the symptoms of asthma and COPD.

    If you only have asthma, symptoms change often, and you may not have any symptoms at first.

    Asthma often involves symptom triggers like exercise, exposure to allergens, or a respiratory illness. It can start in adulthood, but asthma usually begins in childhood. People with asthma often have allergies and eczema.

    If you only have COPD, symptoms may start for some people who are 40 years and older. Symptoms can vary daily, but they're chronic and progressive, even with treatment. Most people with COPD also have a history of smoking or smoke exposure.

    ACOS shares characteristics of both COPD and asthma. People with ACOS experience some type of ongoing airway obstruction.

    They also experience wheezing or breathing difficulties, which often respond to bronchodilators, which are medications that open the airway.

    People with ACOS are often younger and experience more shortness of breath than people with COPD alone. However, because this condition is still being studied, experts do not yet agree on a single definition of the syndrome.

    Because ACOS means you have both asthma and COPD, it's important to look at each condition.

    Researchers don't know exactly why some people develop asthma. You might be more likely to have it if you:

  • have a family history of allergies or asthma
  • smoke or are regularly exposed to irritants such as tobacco smoke
  • have a personal history of allergies, especially if they developed in early childhood
  • had respiratory infections as a child
  • COPD is caused by long-term exposure to lung irritants. In the United States, the most common cause is cigarette smoke. Cigar smoke, pipe smoke, and secondhand smoke can cause COPD, too. So can chemical fumes, cooking fumes, and air pollution. Certain genetic mutations may make you more susceptible to COPD, but this is less common.

    Having asthma doesn't mean you'll develop COPD. However, children with severe, persistent asthma may be more likely to develop COPD later in life.

    ACOS has only recently been identified as a syndrome, so it's not yet clear how many people are affected.

    ACOS means you have symptoms of both asthma and COPD. Your doctor may diagnose asthma, COPD, or ACOS.

    ACOS is a fairly new term. Exact guidelines for diagnosing ACOS haven't been established. ACOS generally involves these three features when compared with people who have COPD alone:

  • more response to inhaled bronchodilators
  • increased reversibility of airflow
  • bronchial and systemic inflammation from eosinophils, a type of white blood cell
  • Your doctor will perform a physical examination and review your clinical history to reach a diagnosis. Imaging tests such as X-rays, CT scans, or MRI may be necessary. You'll likely need a noninvasive test called spirometry, also known as a pulmonary function test, to measure your lung function.

    There's no cure for ACOS. People with ACOS tend to have more hospitalizations and higher healthcare costs. It can also affect quality of life more than those who have only asthma or COPD.

    ACOS is chronic and progressive, meaning symptoms can worsen over time. Treatment and disease management can help keep symptoms under control.

    Your doctor can offer more detailed outlook information based on your age, symptoms, and overall health.

    As far as researchers know, there is no way to prevent asthma, but you can lower your risk of developing COPD. It's unclear if lowering your risk of COPD also lowers your risk of developing ACOS.

    If you have asthma, you may be more susceptible to developing COPD if your asthma is severe and persistent. Managing your asthma is the best way to minimize the disease process. See your doctor regularly, avoid smoke and other lung irritants, and take prescribed medications as directed. Quitting smoking as soon as possible is key.

    Smoking is the leading cause of COPD, and it makes asthma more difficult to manage. If you smoke and can't quit smoking on your own, talk with your doctor about smoking cessation programs.

    From Asthma To Bronchitis, Air Pollution Can Trigger Respiratory Diseases, Here's How To Stay Safe

    As air pollution levels continue to rise, the invisible threat to respiratory health is becoming more worrisome than ever. Smog-filled skies and poor air quality are environmental concerns and also directly impact your lungs, triggering asthma, bronchitis, and other chronic respiratory diseases. Understanding the link between air pollution and lung health is important to reducing these risks and safeguarding your well-being.

    Harmful pollutants such as particulate matter (PM2.5 and PM10), ozone (O3), and nitrogen oxides (NOx) inflame the airway passages, causing difficulty in breathing and exacerbating conditions like asthma and COPD (chronic obstructive pulmonary disease).

    Persistent exposure weakens lung function, leading to shortness of breath, wheezing, and a significantly diminished quality of life, says Dr Harish Bhatia, Founder Director of Rebreathe Clinic and Senior Consultant Chest Specialist & Physician with Apollo Hospital. "The current high smog scenario in India is debilitating for the lungs. Every breath taken in such an environment introduces harmful particles that trigger inflammatory responses, making respiratory management more challenging," he explains.

    Also readManage asthma symptoms: Quit smoking, use inhalers correctly, maintain healthy diet to prevent asthma attack

    Dr Bhatia suggests the following strategies to manage respiratory illnesses in high smog areas:

    Stress management with mindfulness activities: Stress can exacerbate respiratory diseases and disrupt quality of life. Practicing mindfulness activities such as yoga, meditation, and breathing exercises helps reduce stress, promoting relaxation and lung health.

    Healthy diet and regular physical activity: A diet rich in antioxidants strengthens immune defenses while anti-inflammatory foods like walnuts, flaxseeds, and cashews help control asthma and allergic reactions. Exercise is essential, but during seasonal drifts, opt for indoor activities such as swimming, yoga, or walking to protect against outdoor pollution.

    Maintenance of indoor air quality: Clean indoor air minimises asthma and allergic triggers. Regular vacuuming to remove allergens and using air purifiers with HEPA filters to maintain a healthy air quality index (AQI) are highly effective strategies.

    Story continues below Advertisement

    Consume prescribed medications: Managing chronic respiratory diseases requires a consistent medication regimen. Inhaled corticosteroids and long-acting bronchodilators help suppress inflammation, while short-acting beta agonists, such as albuterol, provide quick relief during asthma attacks. Following your medication schedule, even when symptoms improve, prevents future flare-ups.

    Use of air masks: N95 or FFP2/FFP3 masks are highly effective, filtering out over 90 percent of particulate matter 2.5. Wearing masks minimises inhalation of irritants like pollen, dust, and industrial gases, significantly reducing the risk of asthma and bronchitis.
