Canton, MI: Guide to Filters: What is MERV rating?

What is a MERV Rating?

What is MERV? MERV stands for Minimum Efficiency Reporting Value. This rating measures how much matter can pass through your air filter. These values vary and you may have seen this on the side of your filter, possibly a MERV 8 at your home or business. A MERV 8 will trap things such as mold spores, pet dander, dust mites, aerosol sprays, etc. This filter type is the most popular, and what Expert suggests to all of our homeowners.

When looking at a MERV rating you may think that the higher the number the better. However, that is not the case. The higher the MERV rating, the smaller the pores on the filter are. Higher MERV can cause restricted airflow to your furnace. When airflow is restricted this can cause the system to use more energy.

Replacing your furnace filter should be a task that you should always keep on your to-do list. Expert chooses to refer to the replacement track that depending on the width of your filter is when you should replace it. One-inch filters should be replaced monthly, while four-inch filters should be replaced every three to four months depending on the conditions of your home. If you have allergies or pets you should consider changing your filter more often. Expert has a wide variety of filter stocked at our location in Taylor.

If you are worried about filtering your air, there other items that can be considered. Such as the i-Wave R. The iWave is an air purifying device that installs in any system. When air passes over the iWave, ions produced by the device reduce pathogens, allergens, particles, smoke, and orders in the air. By removing these your still will create a healthy environment without producing any harmful byproducts.
