Beat Colds and Flu at Home: The Science of Air Purifiers in Illness Prevention

As we navigate through seasons of illness, the need for cleaner indoor air becomes even more crucial. Enter air purifiers—a beacon of hope for improving air quality and an aid against respiratory illnesses. This blog post aims to shed light on the pivotal role air purifiers can play in not only enhancing indoor air quality but also in supporting our health when we're under the weather. 

The Science Behind Air Purifiers and Illness Prevention

How Air Purifiers Work

Air purifiers draw its surrounding air into the unit. This air is then trapped and passed through a series of filters filtering out harmful particles from the air. Most air purifiers use High Efficiency Particulate Air (HEPA) filters, which trap a  wide range of particles, including pollen, dust mites, and pet dander, which are common triggers for allergies and respiratory issues. The key to HEPA's effectiveness lies in its dense, multi-layered mesh of fibers that capture particles as air flows through the filter. Airdog’s Two-pole Active Filtration (TPA) technology not only traps the smallest of particles, but also destroys these airborne contaminants. This process not only removes harmful substances from the air but also prevents them from recirculating back into the room.

The Role of air purifiers in Trapping Illness-Causing Particles

• Viruses: Depending on the air purifier's filtration process, most air purifiers are able to capture particles as small as 0.3 microns. Higher quality air purifiers such as Airdog’s, are able to capture particles as small as 0.0146 microns. Air purifiers are particularly pertinent for individuals who are sick, as it can also minimize the risk of virus particles spreading to others in the home.

• Bacteria and Mold Spores: These particles, which can exacerbate or even cause illness, are effectively trapped by most air purifiers.By reducing the concentration of these particles in the air, air purifiers can help lower the likelihood of respiratory infections and mitigate symptoms for those already sick.

Reducing Exposure to Fine Particles and Improving Lung Health

A study by the Cleveland Clinic highlights the significant impact air purifiers have on lung health. By filtering out fine particles from the air, purifiers play a crucial role in maintaining a healthy respiratory system. This is especially important for individuals with pre-existing conditions such as asthma or chronic obstructive pulmonary disease (COPD), as well as those currently battling an illness. The reduction of fine particles in the indoor environment can lead to:

• Improved breathing comfort
• Decreased likelihood of respiratory flare-ups
• Enhanced overall lung function

Moreover, the removal of fine particulate matter contributes to a cleaner indoor environment, lessening the burden on the immune system and supporting the body's natural healing processes when sick.

In essence, the science behind air purifiers and their role in illness prevention is rooted in their ability to significantly improve indoor air quality. Air purifiers capture a broad spectrum of harmful particles, including viruses, bacteria, and mold spores, thereby reducing the risk of airborne diseases. The Cleveland Clinic study further emphasizes the positive impact of purified air on lung health, underlining the importance of air purifiers in both preventative health measures and as a supplementary aid during illness recovery periods.
