Air Purifiers for Asthma: They Make A Difference

5 min read

There are many methods available to treat asthma, and one of the most proven ways of controlling symptoms is with the use of air purifiers. Many of the best air purifiers for asthma capture airborne asthma triggers before you can breathe them, helping to prevent asthma attacks before they start. Consider purchasing  air purifiers for each room in your home, as this greatly improves its effectiveness.

It is easy to be overwhelmed by the different home air purifiers available. When shopping, it is important to distinguish what makes each air purifier for asthma different and which health conditions they are best for. The best air purifiers for asthma are generally air purifiers with HEPA filtration.

HEPA Air Filters

Air purifiers with High Efficiency Particulate Air (HEPA) air filters are the some of the best asthma air purifiers. Considered the gold standard in air purification systems, HEPA filters were originally designed during World War II to prevent airborne radioactive contaminants from spreading. The air purifier filter has been commercialized since the 1950s and has evolved to serve the needs of homeowners, hospitals, high tech industries, pharmaceuticals, aerospace, and nuclear power.

Several requirements must be met in order for an air filter to meet the HEPA standard. The air purifier filter must be able to remove 98% of all particles that pass through and must satisfy the standards of the United States Department of Energy (DOE).

Although the United States Department of Energy (DOE) has very strict standards, many companies use the marketing term “True HEPA” to convince consumers that the air filters are certified. This is why it’s important to identify these from those that are labeled using other names such as “99% HEPA” or “HEPA Style”. For the most advanced filtration system in your air purifier for asthma, you can also try an “Ultra HEPA” model.

HEPA filters are able to capture smaller pollutants and particles compared to other air purifiers, making them ideal for asthma relief. In HEPA air purifiers, the particles are trapped by a combination of the following three mechanisms: interception (particles that go through the air stream adhere to the interior fiber), impaction (larger particles are not able to avoid fibers so they embed in one directly), and diffusion (which raises the probability that particles will become stopped through the interception or impaction mechanisms). This HEPA air purifier technology causes pollution particles to stick to the filter media, which makes it far more effective. Brands such as Alen air purifiers or BlueAir air purifiers meet this standard with their use of electrostaticity in the airflow and are considered to be the best air purifiers for asthma.

When choosing the best air purifiers for asthma, there are many things to consider. Important criteria, such as the number of square footage it covers or how simple it is to replace the filter, should be examined prior to purchasing. One of the best air purifiers for asthma on the market is the Alen BreatheSmart 45i Air Purifier. It covers 800 square feet and comes standard with the HEPA-Pure Filter, an easy to use replacement filter. It has an electrostatically charged HEPA filter which attracts even the most stubborn pet dander, pollen, dust, or other airborne pollutants. Another benefit of the Alen  air filter is that it is lightweight and can be wall-mounted. Conveniently, the air purifier for pet dander, pollen, dust and other irritants offers a filter change indicator and has easy-to-use controls with digital displays. The HEPA air purifier also comes with a Forever Guarantee and is Energy Star certified.

Air purifiers have been proven to be highly effective for combating asthma symptoms, per numerous studies. Using a HEPA air purification system, which is the best air purifier for asthma, can maximize the chance to achieve beneficial results.
