To answer questions such as “What is the best air purifier for asthma?” or “Which air purifier is best for asthma?”, many different factors are considered. The first is what are the symptoms of asthma you are trying to eliminate. Asthma can exhibit itself in repeated loss of breath, tightness of chest, difficulty sleeping due to coughing and wheezing, and more. A good air purifier for asthma will remove pet dander, feces, pollen, chemicals, dust smoke allergens, gases, and debris from the air and make it much more whole and easy to pass through the lungs.
Things from outside can find their way inside such as particles from trees, grass, and weeds, or even inside triggers like dust mites, mold odors dust, and secondhand smoke can all clog up the air and thus your breathing passages. Air purifiers are most useful for asthma if they can filter large and small particles alike. This means the HEPA filters are a must. These will remove 99.97% of ultrafine particles which can greatly trigger asthma. However, an activated carbon filter is also a necessity as this will capture the household cleaners and gases that are large particles but can trigger asthma attacks as well, especially to those with sensitive lungs.
Another important thing to consider is that if you are going to be using an air purifier for asthma, you most likely will want to know the quality of your air and the filters at all times. This means it is important to look out for the higher-end models that have air quality monitors that will either always light up to show you if your air is good, okay, or bad and sometimes even turn the system on when it is needed and shut it off when done. A similar monitor exists for the filters themselves so you will never accidentally leave a dirty filter in the air purifier that will limit the success in cleaning the air. This does wind up making the system more expensive, but for those with serious asthma, this is definitely worth the extra money.
It is also a good note that using an air purifier alone will not solve the problems of those with asthma. Using a good dusting and vacuuming schedule can help to bring down the density and volume of pet dander and dust in the house and the air purifier will suck up the rest that flies around in the air after regular cleaning. While this is a lot of commitment, it does really help to keep asthma and allergies in check.
The types of filters present in the model will help to show how good it will be for asthma. The HEPA filter is the first thing to check for, then activated carbon filter to help remove gases, carbon monoxide, VOCs, and odors from cigarettes and pets. The pre-filter is also useful as this will help the important HEPA filter work better and longer too. It is important to note that when using an air purifier for asthma, you will need to spend more money on replacement filters since you want them to operate efficiently.
The last thing to look for when purchasing an air purifier for asthma problems is to ensure that the model is designed for the right size room. Placing a small one in a large room is not going to do anything for that area, so finding one that is meant for the square footage of your room is ideal. Sometimes it is best to buy one for every frequently used room to ensure consistent clean air all over the work or home.

This was then measured again after a few weeks of using the various air purifiers. The ones that provided the most consistent positive decrease in asthma attacks and irritations were deemed the best. This was also based on the overall beneficial features as listed before such as the filter life indicator and the air quality monitor.
Those with asthma showed that these features were very helpful in maintaining peace of mind and could be correlated with lessened asthma symptoms. The overall price and longevity of the filters were then determined to ensure that the ones provided had a decent filter life and were affordable enough.
