What Contaminants Will Air Purifiers Remove?

Having good indoor air quality is as important to your comfort and well-being as moisture control and proper temperature maintenance. A great way to achieve good indoor air quality is to install a whole-home air purifier in Angleton, TX. There are a number of air cleaning products available, and each works differently and has different capabilities when it comes to particle removal. As such, it is important to know which air cleaners are effective at removing which particles. To help understand this, the indoor air quality specialists at Switzerland Air have put together some information describing the different particles that common air purifiers remove.

Factors That Affect Particle Removal

The removal of particles by any kind of air cleaner/air purifier depends on a few factors:

  • Airflow rate
  • Filter efficiency
  • Size of the particle(s)

Mechanical Air Filters

Mechanical air filters are typically used to remove particles that cause problems for allergy sufferers. This would include:

  • Dirt
  • Dust
  • Pollen
  • Pet dander
  • Some mold and mildew spores

Depending on the MERV level of a particular mechanical air filter, some biological contaminants (in which mold and mildew are included), can be captured. The issue lay in the size of biological particles: viruses, bacteria and spores tend to be smaller than particles like allergens; as such, they can be harder to trap. If allergies are the main reason for wanting an air purifier, a mechanical air filter is a good choice.

NOTE: Mechanical HEPA filters can capture many biological particles in addition to particles that cause allergy problems, but these filters are so strong they can restrict air flow. If you are interested in installing a HEPA filter to your system, speak with a professional first.

Electronic Air Cleaners

There are two types of electronic air cleaners: ion generators and electronic precipitators. These types of air cleaners use electricity to charge particles and capture them, although each does it a little differently. Electronic air cleaners can capture many types of particles, including biological ones. However, an electronic precipitator uses metal collection plates to capture particles, and it’s necessary to clean these plates every 3 months in order for the cleaner to remain effective. With ion generators, particles land on the surfaces of your home, and are removed when these are cleaned.

UV Germicidal Lighting

UV lighting is an air purifier designed to specifically target biological contaminants. UV lights use the radiation from UV-C rays to destroy the DNA of cells, as well as the life-sustaining proteins inside them. These actions stop the cell from reproducing and surviving. UV lights do not draw contaminants to them; the particles have to come within the space of the radiation, and UV lights are not effective on particles other than biological ones.

Choosing an air purifier in Angleton, TX will depend on your needs. If you need assistance, schedule an appointment with one of the indoor air quality experts at Switzerland Air.
