Asthmatic person or hyper-sensitive to almost any allergens? While there are lot of ways to tackle this issue, the trustworthy air purifier method is what we will be focusing. In this best list we will be looking at what causes asthma, allergens that is associate with it and who is this for. We hand-picked our top choices based on their efficiency against allergens via 3 key factors: Pre-filter, HEPA filter and Carbon filter. At end of the day you should have a clear idea on which air purifier would be best to partner beside you in the ever-lasting combat against allergens.
What causes asthma?
Asthma is a long-term chronic lung disease that inflames and narrows the breathing airways. Regardless of how mild or severe it is, an untreated asthma can kill within minutes to hours if left untreated. According to study, one third of children that died of asthma had only mild disease. Symptom of asthma include coughing, wheezing, shortness of breath and chest pain/ tightness. Airborne allergens such as pollen, mold, dust mites, chemicals, smokes or even harmless odors could trigger an asthma attack. While there is no cure for asthma, it is treatable and controllable where people with asthma can still live a normal, active lives.
How do we measure?
Who is this for?First would be asthmatic person regardless of gender, age group or how severe the asthma condition is. People with skin allergies that is very sensitive to pollen. People that is hyper-sensitive to allergens, odors and chemicals would benefit from the air purifier as well. Newborn, infant, children, elderly people or recovering patient that has weaker immune system and finally, anyone that wants clean air free from airborne contaminants.
The first one needs no introduction, IQAir air purifier pretty much features in every of our best list sums up how powerful this air purifier is. Rated number 1 room air purifier for allergies & asthma, whether it is a bacteria related microorganism or asthma triggering allergies, IQAir HealthPro Plus strong airflow output together with the excellent PreMax filter, as small as 0.003 microns size HyperHEPA filter, and V5-Cell Gas & Odor filter with Pelletized chemisorption. Combining all that, IQAir HealthPro Plus will ensure no airborne allergens would be able to bypass the filter. Great for whole family or person that is sensitive to allergens as the wide purifying applicable area and 320 degree airflow distribution is perfect for it to be placed in living hall.The trade-off for such a powerful unit is of course the premium price tag that would not fit everyone budget. The bulkiness with all the extra airflow juice means IQAir HealthPro Plus might not be the best choice bedroom either. If pricing is also one of your key concern, consider the budget-friendly Honeywell HPA300.
Another premium category air purifier to go for, Blueair 405 or in fact all Blueair models is known for many good things but its multi-stage filtration against micron size allergens is what we will be focusing on. As some of asthma triggering allergens are known to be trickle to take down due to its size, Blueair 405 would eradicate all thanks to the front ionizer that does the dirty work right before the HEPA Particle/ SmokeStop filter handle the rest. The high CADR and dynamic airflow distribution that will also swiftly capture airborne allergens within its coverage. As a premium model, Blueair 405 also comes with tons of supportive features including Wi-Fi support which you could learn more via the specification button below.As with IQair, Blueair 405 is expensive, bulky and the filters is very costly to replace. If the Blueair brand is a must for you, you could always opt for the non Wi-Fi version Blueair 403 or smaller model such as Blueair 205 to save up come cost.
No surprise Honeywell HPA300 is our bang for the buck asthma air purifier despite not having the most outstanding airflow performance or filtration level. What makes it great is the cost per performance against common allergens where a brand-new HPA300 could cost a few times less than similar large category air purifiers. The combined Carbon Pre-filter would have no issue removing large particles and odors while freeing up space for the True HEPA filter to capture asthma linked allergens and other related irritants. Top it off Honeywell HPA300 also comes with added features including a 2, 4, 8 hours auto-off timer, 300+ cfm CADR, wide 465 sq. ft. purifying coverage and exceptional 5 years warranty.Nitpicking on its downside, Honeywell HPA300 could do well with an air quality sensors and digital display for better usability however given the brand reputation and price you paid, we could be asking too much.
Other than allergens, many things could also trigger Asthma. Things like food, alcohol, scented candles to the weird one such as stress and laughter. While Austin Air Allergy Machine would only handle on the allergens part, it will do a damn fine job. Out of the many variants of Austin Air purifier, we pick the low-maintenance Allergy Machine because it's great against common allergens such as dust mites, pet dander, mold and pollen that are not too kind to asthmatic person. Combining the dual pre-filter, 60 sq.ft. HEPA filter and Activated Military Carbon Cloth (HEGA) filter, no allergens in any type of forms would be able to smack pass the 4-stage filtration.There are 2 version of Allergy Machine to choose form. You could either go with the standard version which is what are reviewing or the smaller Jr model with only airflow delivery rate and purifying coverage to compromise. Both version lacks the bells and whistle of the next item in the list that could be very handy in certain situation.
The alternate, non-WiFi version to Winix HR1000, Winix HR950 is consider one of the best allergens remover thanks to the comprehensive 5-stage filtration. Airborne allergens offer travel in large particles such as dust, skin flakes and pet hair. The preliminary Pre-filter plays a vital role in trapping out large particles while filtering out initial allergens so later stage HEPA filter would have a better efficiency rate. Winix HR950 not only does that, it also comes with Anti-microbial coating on the HEPA filter that inhibit bacteria such as mold, pollen from growing on to the filters. Beside the equally important CD carbon filter and PlasmaWave, Winix HR950 also comes with air quality indicator, particles + VOC sensors, Auto mode, timer and godsend child-lock feature.Nitpicking on WInix HR950 cons, the main one would probably be the pricey annual filter replacement cost although it's still not costliest in the list. For a way cheaper asthma allergen fighter alternative coming from Winix, we highly recommend Winix 5500-2.
If you are impressed by Winix 5-stage filtration, Rabbit Air MinusA2 manage even to top it up with a 6-stage filtration that squeeze it all in a frame size body. The first stage pre-filter would stop large particles mainly airborne dust from floating back out, HEPA filter would trap micron-size bacteria and allergens such as fungi, mold, pollen. With more clean air on every breathe you take, Rabbit Air is the perfect example on how to design a beautiful air purifier that still works wonder for asthmatic person.The downside for such as slim and aesthetically outstanding air purifier is of course the cost of ownership. Everything from the air purifier base price, filter replacement cost and even design panel would cost you. If you are willing to part with 2-stage filtration less we highly recommend the cheaper Rabbit Air Biogs that is also as effective as MinusA2 in tackling allergens.
