The Pros and Cons of Air Filtration

Although many people believe that outdoor air pollution is the most damaging to the lungs, many tend to forget that indoor air can cause problems as well.

When it comes to indoor air pollutants, there are two primary sources, including:

Particulate Matter

This type of pollutant can be found in fireplaces, dust mites, tobacco smoke, pet dander, mold, pollen, heaters, water heaters and stoves.

Gaseous Pollutants

This pollutant can come from anything that can release gas, such as cooking stoves, building materials, cleaning products, pesticides, paints and personal care products.

Can Indoor Purifiers Remove Indoor Air Pollutants?

While indoor air purifiers don’t remove all pollutants in the air, it will greatly depend on what type of purifier you’re looking to buy. When it comes to the many types of purifiers on the market, each model will target specific types of pollutants. With that being said, each air purifier will be able to tackle different types of air pollutants.

The Types of Air Purifiers

1. Electronic – Using a process known as electrostatic attraction, an electronic air purifier will trap the charged particles.

2. Gas-phase – Gas-phased filters will use sorbets, like carbon, to remove any odors or gases from the air.

3. Mechanical – A mechanical air purifier will use a high-efficiency HEPA filter to remove particles by capturing them on fiber or paper.

4. Ozone Generator – An ozone generator will use a UV light to produce something known as “ozone.” This is a harmful lung irritant that can potentially cause more damage to your health. When choosing a purifier, the EPA recommends using a safer method.

5. PCO –  The average PCO cleaner will convert any gaseous pollutant into a harmless product using a UV lamp. Unlike most purifiers, this particular cleaner won’t capture the pollutants.

6. UVGI – A UVGI cleaner will destroy any bacteria or mold using an ultraviolet light. This type of cleaner is commonly used along an air filtration system.

The EPA notes that while an air purifier may reduce the pollutants in the air, it may not cut the health effects caused by the indoor air pollution. Before rushing out to buy a new air purifier, make sure that you know what kind of pollutant you’d like to get rid of.

  1. I really wish more people were aware of the dangers of air pollution. Particulate matter is definitely not a joke. I also think more people need to be aware of the different types of air purifiers that are available to them. Even a single purifier can dramatically increase the quality of indoor air. I really agree with knowing what type of pollutants you want to remove before you make a puchase. For example, dust was a huge concern in my household. This was a very informative article.
