What to Look For in an Air Filter

What to Look For in an Air Filter 1

There are several things you should look at when shopping for an air filter to fit your home. In addition to the MERV rating, consider the material used and the expected life span. These characteristics will influence how well your air filter works and protect your home. For more information, please read the following. Below are the main four types of air filters that are available today. Each type has its unique characteristics. The best indoor air quality will be significantly improved by choosing the right one for you.

Rating MERV

A filter’s MERV rating measures its ability to capture certain contaminants. It is based on the efficiency of filters at capturing particles of different sizes. These particles were created in a laboratory. They measure between 50 and 400 micrometers in diameter. MERV ratings indicate the lowest percentage of particles among six sizes. For example, a MERV of 13 would capture 99% particles of that size.


The Material of Air Filter is an important consideration for the effectiveness of an HVAC system. It helps reduce particulate matter from your HVAC system. There are two types. One uses a fibrous material, the other does not. Filters made from fibrous material use mechanical blocking to keep the airborne particulate out. The particulate matter attached by the fibers narrows the path of air flow, increasing pressure differential between the inflow-outflow sides.

In order to determine the efficiency of your air filter, look for the Minimum Efficiency Reporting Values (MERVs). These numbers are used for comparing the size of particles a filter is capable of capturing. MERVs report the percentage of particles larger than 0.3 microns that are captured by a filter. However, higher MERVs are indicative of greater efficiency. The difference between them is very small. Most filters fall between MERVs 4, and 5.


Air filters have a different life expectancy. This depends on the filter’s material, thickness, pleat count, and filtration strength. The average standard air filter will last approximately three months. But, it may be necessary to inspect it more information often. However, even if you live in an area where winters are short and summers long, the general rule of thumb is every 30 to 90 days.


The MERV rating is a great indicator of the quality of an air filter. Higher MERV ratings are better as they contain more valuable materials and a tighter weave. Higher MERV ratings offer greater protection from allergens and other pollutants in your air. If the air around your home is not that clean, a higher MERV rating is the best option. You should also consider the filter’s lifetime if you are concerned with the cost.
