Air filters play a big role in the air quality of your home. These filters collect dust, dirt and other debris, preventing it from circulating around the house. Additionally, changing out these air filters on a three month basis (although you may want to lean towards two with the amount of dust and dirt in the air here in Oklahoma) reduces the monthly energy bills. However, when you go to the store, you’ve probably noticed a handful of different filter options within the size perimeters you need. Which option is right for you? It depends on what you’re looking to spend and your particular needs. Understanding the difference can go a long way in selecting the right cooling and heating features of your home.

The MERV Rating

Whenever working with an HVAC cooling and heating specialist, they may talk to you about a filter’s MERV rating. The rating is designed to show how a filter reduces particles form the air, assists in airflow and the operating life of the filter. The lower the rating, the lower quality the filter is (meaning more particles tend to fly through and the operating life is stunted). The American Society of Heating, Refrigerating and Air=Conditioning Engineers (ASHRAE) designed the MERV rating system.

Fiberglass Flat-Paneled

This is a base level air filter with a rating running anywhere from 1 to 4. There is a thin metal grating that reinforces the filter and prevents it from collapsing. These are the least expensive options you’ll find at the store, but the filters do a poor job at removing dust, dander and bacteria.

Pleated Media Filter

With a rating from 5 to 13, these filters offer a nice step up. It is a low price point and does a fine job removing larger debris, but isn’t great with dust.

With a rating between 17 and 20, these home filters can block anything larger than .3 microns.
