2019 Best Air Purifier for Asthma and Allergies

Asthmatic person that is hyper-sensitive to almost anything? Stick around as we hand-picked the best air purifier for asthma and allergies currently available. In this post, we will briefly go through the preventive measures and then focus on the air cleaner method. we will also touch on the root cause of asthma, what allergens commonly associated with it and who is this for. At the end of the post, you will know which air purifier is the best to partner you in the ever-lasting battle.

What causes asthma?

Asthma AKA bronchial asthma is a chronic lung disease that inflames and narrows the breathing airways. It happens when the tubes that carry air in and out of your lungs become inflamed. It causes the surrounding muscles to become tight and swollen. As a result, the airway is narrower making it hard to breathe. Not only that, more mucus will be produced that adds to the obstruction. Those who suffer from asthma will likely have a bad reaction when inhaled to harmful substances. Most of the asthma symptoms above can be between mild to severe if the condition is persistent. If asthma is in mild status, the symptoms will likely go away on its own without any consequences. If it is in severe status (multiple symptoms), asthma will likely flare-up and can be fatal if is left untreated.

Regardless of how severe the condition is, untreated asthma can kill within minutes. One-third of children that died only have mild intermittent asthma. An asthma attack is often triggered by allergens such as pollen, mold, dust mite, smoke or even odor. While there is no permanent cure, it is controllable where people can still live a normal, active life. A HEPA air purifier would help reduce the numbers of airborne triggerers indoor.

How do we measure?
Pre-filter Believe it or not, dust and hair do trigger asthma. What's worst is the allergens i.e. dust mites, pet dander, pollen that travels along. A good pre-filter will stop large airborne particles from flowing to the next stage. It will also reduce the dependencies of HEPA and carbon filter for best efficiency. What we are looking for is a dependable pre-filter whether in the form of a permanent or 2-in-1 carbon filter.
HEPA filter HEPA or high-efficiency particulate air is the key ingredient to fight against allergies. Common allergens e.g. pollen from a tree, dust mites on mattress and chemicals from paint are what often trigger asthma. A good HEPA filter not only captures all that, it will also capture other micron size allergens. Our criteria are simple. The HEPA filter must have the capability to capture the aforementioned household allergens. Only then we will look at the compatibleness with its pre-filter and carbon filter.
Activated Carbon filter Little do people know that good or bad odors can trigger an asthma attack. Example of good odors coming from food, flower, or perfume. Bad odors such as mold musty smell, detergent fume, cigarette smoke, or VOCs. The carbon filter must be able to filter out all smoke-based particles before we inhale it to our lungs. The deodorization filter must also play nice with the previous two filters.

Who is this for?

An asthmatic person would be first in line regardless of gender, age group or race. People that are hyper-sensitive to allergens and odors would benefit from one as well. Newborn, infant, children, elderly or recovering patient that has weakened immune system. Finally, anyone that wants clean air with as little airborne contaminants as possible.

The first one needs no introduction. Rated number 1 room air purifier for allergies, IQAir features in almost every of our list. The strong airflow combines well with the excellent PreMax, HyperHEPA, and V5-Cell Gas & Odor filter. Whether is germs, smoke, and odors, nothing is impossible for the air purifier. Airborne allergens as small as 0.003 microns size (Yes you read it right) would not be able to bypass the filter. The wide purifying and 320-degree distribution also means it is great for the whole family staying with an asthmatic person. IQAir HealthPro Plus is perfect to be placed in living hall.

The trade-off for being the absolute best air purifier for asthma is the premium price tag. Not only it will not fit into everyone's budget, but the bulkiness also makes it a slight overkill for bedroom use. If pricing is one of your key concern, consider the much more budget-friendly HPA300.

What's cool:

  • Made in Switzerland with certified quality and performance.
  • HyperHEPA filter that can trap particles as small as 0.003 microns.
  • Excellent smoke removal V5-Cell MG Carbon filter with Pelletized chemisorption filter.
  • Long-lasting filter that will last between 2-4 years.
  • Exceptional purifying coverage with a 320-degree airflow distribution.
  • 10 years warranty.

What's not:

  • Flat price that cost at the range of 900 dollars.
  • Very bulky and heavy compared with other air purifiers here.
  • No auto mode or sleep mode to compliment the filtration.

Another premium air purifier for asthma and allergies to go for. Airmega is known for many things but the superb HEPA filtration is what we will be focusing on. Irritants like bacteria and viruses are tricky to take down due to their microscopic size. With a HEPA filter, none of this asthma aggravator stands a chance. The same theory applies to the carbon filter that handles smoke/ odor with ease. As a premium model, Airmega 300 also comes with tons of features like timer, Auto/ Sleep mode. All S variant gets additional Wi-Fi support for remote access.

Like IQAir, Airmega 300 is an excellent air purifier with dynamic airflow distribution. However, it will cost you a bomb in the long-run when you include the expensive replacement filter set. Since Airmega is also part of the Coway brand, you could always opt for the cheaper Coway Mighty.

What's cool:

  • Extensive 1256 sq. ft. purifying coverage with decent CADR.
  • Dual pre-filter that will trap large particles from both sides of the air purifier.
  • Outstanding Green True HEPA filter against microscopic particles.
  • Carbon filter that can target musty mold smell in your home.
  • Built-in timer, air quality display indicator, and Auto mode.

What's not:

  • Expensive despite a significant amount of online discounts.
  • Lacks autonomous sleep mode activation.
  • No ionizer.

A highly endorsed air purifier by fans all over the world. Coway Mighty might be a dark horse given its long-existing timeline, it still has plenty of say here. Why why do we think this is probably the best air purifier for children with asthma? First, it passed with flying colors for its trinity filtration (pre-filter, HEPA, and Carbon filter). Second, the air purifier decent airflow delivery provides swift allergens and odors removal. Last and perhaps more significantly, the pricing work as it’s accessible to everyone. In short, if you need a solid, dependable yet reasonably price air purifier, Coway AP-1512HH is your call.

Non-allergy related issues, since it's been in the market for a while, it does not have the techiest design. There are also few complaints about the after-service support or the lack of it. Things probably changed (improved) due to the recent branding tied back with Airmega.

What's cool:

  • Less than $150 for a proven 4-stage filtration.
  • Less than $50 for the annual filter replacement. Comes with separate HEPA and Odor filter change indicator.
  • Impressive 326 sq. ft. coverage with above 200 cfm for all CADR.
  • Pre-filter, True HEPA filter, deodorization, and ionizer all comes standard.
  • Timer, auto mode, eco mode, and sensor comes with 3 adjustable preset setting.

What's not:

  • Rather short carbon filter lifespan.
  • Awkward position on its air quality indicator.

No surprise here. Honeywell HPA300 is our bang for the buck air purifier for asthma and allergies. What makes it great is the cost per performance against common allergens. A brand-new HPA300 is priced a few times less than other large room size category air purifiers. Going inside, the carbon pre-filter would have no issue trapping large particles/ odors. At the same time, it will free up space for the True HEPA filter to capture smaller irritants. Top it off with the outstanding 300+ cfm CADR and wide 465 sq. ft. purifying coverage for any room size.

Nitpicking on its downside, HPA300 usability could be a lot better. it could do with air quality sensors and digital display for better readability. However, given the brand reputation and the price you paid, we could be asking too much from it.

What's cool:

  • Less than $200 for a very powerful air purifier with exceptional 300+ cfm.
  • Above 400 square feet purifying coverage.
  • Trio True-HEPA filter that is super effective against indoor pollutants.
  • 3 pre-set timer.

What's not:

  • Very basic features. Not even Auto mode.
  • Slightly expensive filter replacement cost (3 filters).
  • Use carbon pre-filter rather than a dedicated carbon filter.

Food, scented candles to stress, and laughter could potentially aggravate asthma. While there is no air purifier in the world able to "filter" out laughter, Allergy Machine will do a fine job handling the rest. Out of the many Austin Air variants, we pick the low-maintenance Allergy Machine as an example. From the name itself, you'll know it is effective against irritants that are not too kind to an asthmatic person. Combining the 60 sq.ft. HEPA filter and HEGA filter, no allergens would be able to bypass the 4-stage filtration.

There is 2 version of Allergy Machine to choose from. You could either go with the standard version which is what we are reviewing or the smaller Jr model. Junior model is cheaper and with only airflow delivery to compromise. What both version lack is the practicality gadget that is in the next asthma air purifier.

What's cool:

  • Very wide 1500 sq. ft purifying coverage (lowest air changes).
  • Pre-filter and medium filter to capture pet dander and dust mites.
  • Activated military-grade carbon HEGA filter for indoor chemical fumes.
  • 60 sq. ft. certified HEPA filter for asthma causing bacteria and viruses.
  • Powdered coated steel with no toxic off-gassing.

What's not:

  • Bulky and heavy body.
  • Hassle filter changes that require unscrewing.
  • Lacks auto mode, sleep mode, and air quality indicator. Not even a timer.

AOC Advanced Granular Carbon Filter

Easily one of the best air purifier for asthma around. Winix 5500-2 is one of the best allergens removers thanks to the awesome 4-stage filtration. The preliminary Pre-filter plays a vital role in removing large particles including dander. Next, the protected HEPA filter would then focus on trapping microorganisms. The carbon filter and PlasmaWave will now eliminate any leftover smoke/ odor particles. Did we mention AQ indicator, Auto mode, timer, and godsend child-lock features is in its spec sheet?

There must be a few downsides, none so than the slightly pricey annual filter replacement. Even though it's not costliest in the list, but in a short few years, the filter cost will overtake the selling price. For a way cheaper asthma fighter air purifier, consider Winix 5300-2 that has to compromise with weaker carbon filtration.

What's cool:

  • Less than $150 full-fledged console air purifier.
  • High 360 square feet coverage with respectable 200+ cfm CADR.
  • Super attractive price (after online rebate) when you consider its specification.
  • True-HEPA filter that will protect asthmatic sufferers against microbes allergens.
  • Standalone AOC carbon filter that will cigarette smoke and other toxic triggers.
  • Auto, Sleep mode, built-in timer, and remote control.

MinusA2 Charcoal-Based Activated Carbon Filter

Another regular sitter in the list. If you are impressed by Winix 5-stage filtration, Rabbit Air MinusA2 will blow your mind off. It is a 6-stage filtration squeezed it in a frame size body. The first stage pre-filter stops airborne dust, hair filled with allergens. Without the pesky large particles, microbes will now have to go through a long journey of purification. Starting with a medium filter, HEPA filter, and a customized filter (Any will do). Any uncaptured smoke will be taken care of by the Charcoal-Based activated carbon filter. Finally, the negative ion generator will charge up any particles for the next cycle. This is the prime example on how to design a beautiful air purifier that still works wonders.

Nothing makes an asthmatic person feel safe surrounded with purified, clean air. The downside for such an aesthetically outstanding air purifier is the cost. Everything from the base price, filter add-on, and even design panel would cost you top dollar. There is a cheaper non-WiFi version that will save you a couple of bucks. If you are willing to part with 2 less filtrations, we highly recommend the cheaper Rabbit Air BioGS.

What's cool:

  • Inexpensive filter replacement cost despite having so many filters.
  • Wall-mountable, square design with mood light color.
  • Complete 6-stage filtration with Pre-filter, Medium and HEPA filter, AC carbon filter, and 4 Customizable filter options.
  • Auto mode, pollen mode, light-sensitive sleep mode, and adjustable sensitivity sensors.

What's not:

  • Optional filter and front panel design available for extra cost.
  • Expensive yet with only above average CADR and airflow coverage.

Frequently Asked Questions FAQ

Do Air Purifiers Help with Asthma

An air purifier will reduce the risk of an asthma attack by capturing all indoor allergens in a room. You will breathe better without all the asthma symptoms pestering you. Smoke and odors can also aggravate asthma conditions. With a carbon filter, an air purifier will also remove the cooking smell or chemical fumes from cigarettes. Keep in mind that an air purifier needs to be running all the time to ensure any incoming irritants are captured. Also, if the irritants are not airborne e.g. dust mites on the pillow, carpet, there is nothing an air cleaner could do until the particles are disturbed.

In short, dust, pollen, mold, mildew, bacteria, and viruses will be removed from the air from triggering asthma. If you are an asthmatic person, smoker, living with a smoker or have children, an air purifier will do wonders for your lungs.

What Types Of Air Purifiers Are Best For Asthma Sufferers

There are many different types of air purifiers in the market but HEPA air purifier is proven to be the most efficient one.

You can even get models that come with extra filtration i.e. pre-filter, carbon filter, ionizer or UV-light.

Asthma Facts and Figures

Asthma is a chronic lung disease that you should not take lightly upon. Many people assume since it is a very common condition that happens among our peers and friends, an inhaler would probably do the trick. Unfortunately, there are simply too many horrid cases that lead to death even at a young stage. Most of this death is preventable is a safety-precaution is taken in the first place. Let's take a look at some of the scary asthma statistics from AAFA.

  • Asthma affects more than 25 million Americans; 6-7 million are children.
  • Asthma is the top reason for children missing school days. In 2013, about 13.8 million missed school days because of asthma.
  • There are about 6.2 million children under the age of 18 with asthma.
  • About 4,000 people die of asthma annually in the United States. Many of these deaths are avoidable with treatment and care.
  • Adults are 4 times more likely to die from asthma than children. Women are more likely to die from asthma than men and boys are more likely to die than girls.
  • 60-65% of breathing problems linked with asthma from children could be mitigated with an air purifier.
  • Asthma has been on the rise since the early 1980s in all age, sex, and racial groups. Part of the reason is due to the increasingly poor air pollutions exposure.
  • According to CDC, 1 in 13 people have asthma while 1 in 12 children has asthma.
  • Asthma is more common in adult women than adult men. However, asthma is even more common in children than in adults.
  • On the flip side, Asthma is more common in boys than in girls.
  • More than 11.4 million people with asthma including 3 million children had one or more asthma episodes or attacks.

Best Place to Place An Air Purifier In Home For Asthma

The bedroom would be the best place for an air purifier as we spend at least 6-8 hours a night or one-third of our life. If you are sure that's not the place with a higher risk of asthma kicking in, consider the living hall, kitchen, offices or even basement. When choosing a spot for the air purifier, make sure not to squeeze it in a tight corner that could block the airflow circulation. Also, never place the air purifier underneath windows or next to electronic devices to avoid damaging the machine. For optimum results, get an air purifier for every room so no airborne pollutants will be able to escape.

What Are The Early Symptoms of Asthma?

Most asthma symptoms are related to respiratory infections triggered by exposure to irritants. Children are susceptible to asthma symptoms and will show some signs before they turn 5. This is because of the bronchial tubes in infants or toddler is very small and narrow. A slight irritation will lead to the airways to be easily inflamed with symptoms that can last for days or weeks.

Sometimes it is hard to tell if the symptoms experience is cold, bronchitis or asthma. A good indication to tell if it is due to asthma is on the occurrence frequency. Asthma will tend to have several of the symptoms below and will last on a longer period of time.

Common Signs of Asthma

  • Chronic cough especially at night
  • Cough during exercise or when laughing
  • Difficulty breathing/ breathing through the mouth
  • Rapid breathing
  • Wheezing (whistling sound when breathing)
  • Chest tightness
  • Shortness of breath

6 Different Types of Asthma

According to ACAAI, there are many different types of asthma triggered by different sources. While an allergist can provide you with a diagnosis and identifying the causes, let us go through all 6 common types of asthma.

  • Adult-Onset Asthma - Asthma that is only developed in adulthood. This could be because a person has not exposed to asthma triggers throughout their childhood. Another reason is because of a respiratory infection that only unmasks the asthma symptoms in a later stage.
  • Allergic Asthma - The most common form of asthma. Allergic asthma is triggered by inhaling airborne allergens.
  • Asthma-COPD Overlap (ACO) - When you have symptoms of both asthma and chronic obstructive pulmonary disease (COPD). Less common but more severe asthma condition associated with breathing difficulty.
  • Exercise-Induced Bronchoconstriction (EIB) - Essentially the narrowing of the airways that makes it difficult to move air out of the lungs. A condition that can occur in people with or without asthma.
  • Nonallergic Asthma - The opposite of Allergic Asthma. Nonallergic Asthma is triggered by Illnesses, medications and environmental factors. It does not involve an immune-system response.
  • Occupational Asthma - In short asthma happens in the workplace. It is a lung disorder that causes the airways to swell and narrow.
