Which Air Filtration Systems Work Best in Your House?

While we typically think of air quality in terms of outdoor levels of mold, pollen, or ragweed, indoor air quality (IAQ) is even more important. That’s because most Americans spend up to 90% of their time indoors. Factoring in those people with allergies or other respiratory complications makes that percentage even higher. Given this, if you’re going to invest in an air filtration system, you need to make the best choice for you and your family.

3 Types of Air Filtration Systems

In our opinion, a whole-house system is always your best option. Smaller, portable units are only effective in limited areas, you’ll need to buy multiple units to use throughout your house, and it will be difficult to maintain uniform air quality throughout your home.

In addition, you’ll want to contact your local air filtration systems experts to make sure the installation and follow-up maintenance are done right.

1. High-Efficiency Particulate Air (HEPA) Technology

HEPA filters collect incredibly small particles: 99.7% of all particles larger than three microns. (The human eye can only see objects as small as ten microns.) Larger particles are immediately trapped by HEPA filter fibers which overlay each other like an accordion. Smaller particles are captured by either interception, impaction, or diffusion. These filters depend upon airflow to trap particles, so once the filter is “full,” it will need to be replaced, but this will take two to three years.

These filters do not remove odors, however, and are typically used in conjunction with a carbon filter.

2. Activated Carbon Technology

These filters consist of carbon sheets containing molecular-sized pores which trap gasses, smoke, and chemical emissions. In fact, this technology dates to WWII when it was developed for gas masks.

Most people are more sensitive to the particulates captured by HEPA filters, but activated carbon technology is especially effective for people who have Multiple Chemical Sensitivity (MCS). Formaldehyde, perfumes, and other pungent odors are removed which is especially beneficial for the elderly and children who may have respiratory issues.

3. Ultraviolet (UV) Technology

UV systems are often used in conjunction with HEPA or activated carbon filters as they don’t collect particulates. These systems do, however, kill mold, germs, viruses, and bacteria. Another reason for using a particulate system in conjunction with a UV system is because too many particles in the air will keep organisms from receiving enough direct UV light to be destroyed. This system’s effectiveness is determined by the strength of the UV light as well as the length of exposure organisms receive.
