What Air Filter Do I Need? Here’s How To Find The Perfect Fit

Air filters are essential for maintaining good indoor air quality in your home. They trap dust, pollen, pet dander, and other particles that can aggravate allergies and asthma. But with so many different types of air filters on the market, it can be difficult to know which one is right for you.

Types of Air Filters

There are three main types of air filters:

• Fiberglass filters are the most common type of air filter. They are made of fiberglass fibers and are available in a variety of MERV ratings.
• Pleated filters are made of pleated paper or fabric. They have a higher MERV rating than fiberglass filters and are more effective at trapping smaller particles.
• HEPA filters are the most efficient type of air filter. They are made of HEPA-rated material and are capable of trapping 99.97% of particles 0.3 microns or larger.

MERV Rating

The MERV rating is a measure of how effective an air filter is at trapping particles. The higher the MERV rating, the more effective the filter.

For most homes, a MERV rating of 8 to 12 is sufficient. However, if you have allergies or asthma, you may want to choose a filter with a higher MERV rating.

Size

Air filters come in a variety of sizes. It is important to choose a filter that is the right size for your furnace or air conditioner. The filter size is usually printed on the side of the filter.

How Often to Change Your Air Filter

You should change your air filter every 30 to 90 days. However, if you have pets or allergies, you may need to change your filter more often.

Changing your air filter is a simple process.

1. Turn off the furnace or air conditioner.
2. Locate the air filter. It is usually located in the return air duct.
