Improve Indoor Air Quality This Winter With an Air Filtration System

Improve Indoor Air Quality This Winter With an Air Filtration SystemHomeowners in Grand Traverse County interested in improving indoor air quality have many options, including air filtration systems. Selecting the best option for your home is a matter of balancing expenses, benefits and maintenance requirements. 

Mechanical Filtration

Improving indoor air quality with mechanical filtration means physically blocking particulates in the airflow within your home’s ductwork. Media for these filters vary, including:

  • fiberglass
  • cotton
  • pleated synthetic fibers

These filters can be thin, like disposable fiberglass filters or very thick, such as professionally installed deep-media filters.

Electronic Filtration

Electrostatic charges can draw airborne dust and pollutants out of your home’s airstream. These particles receive an electrical charge and are attracted to oppositely charged metal plates and grounded filter material.

Electronic systems should not be confused with electrostatic filters, which generate the charge from the filter fibers. Here, one layer of material—often synthetic—imparts an electrical charge and another layer draws the pollutants to its surface, trapping them.

Effectiveness

The Minimum Efficiency Reporting Value (MERV) rating tells you how well a mechanical filter works. The ratings, from one to 20, provide a rough gauge of the types of pollutants the filtration intercepts:

  • MERV 1-4—large particles; minimal filtration; lowest quality residential protection; common in disposable filters
  • MERV 5-8—smaller particles; better quality residential protection; common in pleated filters
  • MERV 9-12—blocks almost all particulates; best quality residential protection; seen in cartridge and rigid cell filters
  • MERV 13-16—hospital grade; too obstructive for residential use (blocks airflow and robs your system of efficiency)
  • MERV 17-20—clean rooms; not practical for residential use

High Efficiency Particulate Air (HEPA) filtration is not measured under the MERV system due to its high level of efficiency.

Maintenance

Some air filters designed for improving indoor air quality require professional servicing. Disposable filters can be replaced by the homeowner. Electronic filters need to be cleaned and wiped down periodically, while HEPA filters may only need annual or biannual replacement.
