Whole-House Air Filtration or Cleaning: 4 Types

Whole-House Air Filtration or Cleaning: 4 Types

The air in your Dayton-area home does carry pollen, dust and other contaminants throughout your house. A whole-house air filtration or cleaning system within your furnace’s ductwork greatly helps eliminate these before they can lodge in your family’s lungs.

Ultraviolet Cleaners

Whole-house air filtration is thought to be as powerful as ultraviolet germicidal irradiation (UVGI). Ultraviolet (UV) light disrupts the DNA of many small organisms such as viruses and bacteria. UVGI is not a filter however; it purifies your air by killing germs. Often used in medical applications and clean-room technology, UVGI is also not a do-it-yourself job. Your job? Changing the UV bulb biannually.

Electronic Cleaners

Electronic air cleaners, like UVGI, are not filters either but help to rid your household air of particulates:

  • volcanic ash
  • animal dander
  • sand
  • human skin cells
  • food crumbs
  • insect parts

Besides organics killed by UVGI, these are all a mix of the ocean of air in your Dayton home. An electrostatic precipitator (ESP) forces a high-voltage charge through the air in your ductwork, charging particles and then causing them to electrically stick to a collector. ESPs work on smoke particles, but UVGI and mechanical filters do not. While a whole-house air filtration system using ESP must be installed professionally, portable models exist at a reduced cost. The portable units, however, emit ozone, a lung irritant.

Thin Filters

The thin, rectangular filter connected with furnaces is either pleated or flat and does require monthly changing to be effective for whole-house air filtration. Your furnace is designed to operate most efficiently at a specific airflow. Clogged filters greatly affect furnace efficiency and increase fuel costs. Pleated thin filters are often better than flat filters.

Thick Filters

Imagine five or six pleated filters stacked and shoved into the airflow inside your ducts. A thick filter, some 8 inches of pleated medium that requires annual replacement at 12 times the cost of a single pleated filter, must be professionally installed into the return air plenum of your ducts. It does deliver an excellent job intercepting airborne contaminants.
