Media Filters for Allergies
Indoor air pollution can be a problem. Dust mites, mold spores, pollen, and pet dander in the air inside your home can cause problems if your family has allergies or asthma. Using Media filters can trap these pollutants and may help bring allergy relief.
Media stands for high-efficiency particulate air. A Media filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.
What is Merv Rating?
MERV means Minimum Efficiency Reporting Value which was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers – ASHRAE. MERV values vary from 1 to 16. The higher the MERV value is the value the more efficient the filter will be in trapping airborne particles going through the system and recycled through the register vents into your home.
MERV scale ranges from 1 to 16, and measures a filter’s ability to remove particles from .30 to 10 microns in size. To give you an idea of the scale of a micron, 100 microns is about the thickness of a piece of paper or a human hair. Filters with higher ratings not only remove more particles from the air, they also remove smaller particles.
