Protect Indoor Air Quality with an Air Filtration System

Apr 17, 2012

Air quality has become one of the highest priorities of the Environmental Protection Agency (EPA).

With the rise energy prices dramatically increasing the cost of home heating and cooling, a focus on air sealing of homes has emerged in order to contain costs. However, with more tightly sealed homes, the indoor air quality can suffer. Specific attention must be paid to keeping the air inside your home fresh and circulating regularly. This is where proper ventilation and air filtration systems come in.

Air Filtration Systems Target Different Needs

Air filtration systems can be installed to meet the needs of any home, but first you need to know what your needs are. For instance, if you live in a damp climate you would do best to purchase an air filtration system that combats mold. If you or your family members suffer from allergies, there are systems that combat pollens and pet dander.

By hiring a certified RESNET air filtration consultant to assess your home and your family’s needs, you can choose the most appropriate system for your needs. Some of the options available include:

  • Ionizers: An ionizing filter emits a small electric charge to an air stream which creates a magnetic-like attraction for particles causing them to stick to the filter.
  • Electrostatic precipitators: Creates opposite charges on metal wires or plates which attracts and holds dust, pollen, smoke and other particles as small as .0001 microns on a reusable filter.
  • Ultraviolet light purification: Passes air through an ultraviolet system that destroys bacteria, viruses, and dust mites of any size.
  • High Efficiency Particulate Air (HEPA): These filters are extremely effective at capturing any airborne pollutants .3 microns or larger, including tobacco smoke, dust, and pollens. HEPA filters remove 99.97% of the particulates that pass through the filters, but they do not remove bacteria or mold spores. The filters must be replaced regularly.
  • Ultra HEPA: A more efficient version of the HEPA, it is claimed that these filters will remove 99.9% of airborne pollutants.
