Types of Air Filters to Consider

Air filters come in many types and strengths. The MERV rating determines how well a particular filter traps contamination; most residential filters have a MERV rating between 8 and 13. It’s important for you to have professionals determine the right MERV rating for your home, or else one that is too powerful could end up blocking airflow from the heater and air conditioner, running up your bills while delivering inferior comfort.

There are two broad categories of air filtration systems available:

• Mechanical filters: These are the basic air filters that consist of a mat of fibers which prevent contaminating particles from passing through. Mechanical filters work very effectively, and they require no extra power and are easy to replace when necessary.
• Electrostatic filters: These are filters that clean the air passing through them by using the power of static electricity. An electric charge moves through the fibers, and this attracts particles to them and traps them. Although not suitable for all situations, electrostatic air filters can usually do a more effective job at removing particles from the air in a home than mechanical filters.
