Did you know that the air inside your home contains millions of small particles that include pollen, dust, pet dander and other pollutants? These indoor air pollutants have the ability to trigger sniffling, sneezing and other types of asthmatic symptoms. Fight off these symptoms with proper air filter maintenance.

Air Filters and the Air You Breathe

Reducing indoor air pollutants simply begins with basic maintenance. There are certain steps you can take to help minimize your family’s exposure to harmful indoor air particles. Maintaining your HVAC air filters is one important task that we constantly stress to all of our customers. It will not only help with cleaning the air in your home, but it is also vital to the overall efficiency of your unit. Filters are designed to prevent airborne particles from entering into your HVAC system. A HVAC system that has dirty filters reduces the airflow of your unit, and it prevents proper infiltration of air pollutants that are found in the air throughout your home.

Types of Air Filters

It is important to use the correct type of filter to ensure that your HVAC system is working at its peak performance. There are many different types of filters available. They all have different capabilities based on the density of the material used to make the filter, the size of the filter, as well as the volume of the particles being filtered.

The most common HVAC air filters today offer MERV ratings, also known as the minimum efficiency reporting value. This scale rates the effectiveness of filters based on two important factors:

  • The ability to remove large particles, also referred to as microns. Dust mite debris, pet dander, mold, spores and pollen are examples of microns.
  • The ability to remove submicrons. The particles sprayed in the air from aerosol cans are examples of submicrons. This rating is called microparticle performance rating (MPR). Sometimes you will find that filters will only contain this rating.

MERV ratings range from one to 20 based on the level of filtration desired. Examples of these ratings:

  • A MERV rating of one through four is typically used for residential air conditioner window units. It is excellent at removing contaminants such as pollen, carpet fibers, dust mites and cockroach debris.
  • A MERV rating of five through eight is considered the better option for residential homes. It removes mold, pet dander, spores, dust mites and hair spray.
  • A MERV rating of 9 through 12 is considered superior in controlling residential contaminants.
