Monitoring Air Quality is Important, Too

Monitoring air quality is crucial because it helps us track the levels of pollutants in the air and identify problem areas. It can also alert us to potential health risks associated with air pollution. By monitoring air quality, we can take steps to protect our health and the environment.

Running an air purifier is important because it can help reduce the level of pollutants in the air, such as dust, smoke, pollen, and other allergens. Air purifiers work by trapping airborne particles in their filters so that they don’t enter our respiratory system when we breathe. This helps to reduce a person’s risk of experiencing health issues related to poor air quality, such as asthma or allergies.

How Air Purifiers Work

An air purifier draws in air from the surrounding environment and passes it through a multi-stage filtration system. The first stage usually consists of a pre-filter layer, which captures larger particles such as dust and pet fur. Then, the air passes through multiple additional filters, which can capture smaller particles, including allergens and contaminants. Finally, some air purifiers may also use other technology, such as activated carbon or an ozone generator, to remove odors.

Activated carbon absorbs particles and molecules that cause odors, while ozone generators produce reactive oxygen that breaks down odor-causing molecules. Combining these multiple filtration stages and technologies, an air purifier can accurately remove airborne pollutants, odors, and allergens.

The video below explains this somewhat complex process in an easy-to-understand way and is worth a watch if you’d like to learn more.

You’ll also hear much about HEPA, but what does this mean?

HEPA filtration is an air filtration system that uses high-efficiency particulate air (HEPA) filters to remove particles. HEPA filters are designed to capture at least 99.97% of airborne particles that are 0.3 microns in size or larger, making them highly effective at removing dust, pollen, mold spores, pet dander, and other types of airborne contaminants from indoor air. While more expensive, HEPA air purifiers are highly recommended for those sensitive to airborne pollutants.

Can Running An Air Purifier Protect Me From Airborne Illnesses (Like COVID)?

Running an air purifier can help reduce the risk of airborne illnesses by trapping particles and impurities, such as dust, pollen, pet dander, and other contaminants.
