How Does an Air Purifier Work


Believe it or not, spring is just around the corner. Along with warmer weather, spring brings another companion: allergy season. Is your home prepared to face the onslaught of dust, pollen, and plant spores that come from an unfiltered air supply?  If allergies and asthma are a concern for you, you should consider installing an air purifier into your household.

What Does an Air Purifier Do?

The air in your home is typically dirtier than the air outside. Inside your home, moisture can lead to mold growth. Forced-air heating and cooling systems move dust and bacteria particles throughout your household. Pets shed fur and give off dander. Pollen and other foreign particles can be captured in the fibers of your carpet. The inside of your house is a breeding ground for an unhealthy environment. An air purifier works to eliminate undesirable airborne particles in your home to provide a cleaner, healthier environment.

How Does it Work?

Air purifiers come in a variety of different makes and models. Some models work by having air pass through a filter to clean the air. Oftentimes, these are called air cleaners. As part of a furnace system, the filter cleans the air as well as prevents damage to the water filter, filter, carbon filter, activated carbonfurnace due to dust and dirt build-up. A filter’s efficiency is reliant on the density of the filter media. Very dense filters have smaller gaps, preventing even the smallest of particles from passing through the tiny gaps. Pleated filters have an increased surface area for catching a larger number of particles. Some types of filters are washable and renewable. These filters are effective at catching undesirable particulate in the air and preventing them from entering your indoor environment.

How Effective can an Air Purifier Really Be?

While ionization and ozone methods of air purification have gone under criticism for their effectiveness, air filters as part of an air purification system have shown to drastically improve air quality in indoor spaces. The particle-capturing nature of the filter media significantly removes unwanted particulate such as dust and pollen that can trigger allergies, asthma, and other respiratory problems from the air supply while allowing clean air to pass through with ease. Proper filtration of air can lead to increased health benefits, reduced energy costs, and crisp, clean air throughout your entire home.
