Fiberglass Air Filters: The Advantages and Disadvantages of using them In Your St. Louis Area Home

5.0 Rating

small_2141235132Fiberglass air filters are some of the most commonly used filters in St. Louis area homes. Although there are some good reasons to use fiberglass filters, they aren’t always the best option for homeowners. Today we’re going to talk about what fiberglass air filters are and the advantages and disadvantages of using them with your heating and cooling system!


What are fiberglass air filters?


Fiberglass filters are the 1 inch blue filters that can be found at most hardware and large retail stores. They are made of spun glass that captures large particles from your home’s air, and typically come with a MERV rating between 1 and 4.


Fiberglass filters are often referred to as “throwaway” or “disposable” filters because they are only designed to last around 30 days before they need to be thrown away and replaced.


What are the advantages of fiberglass air filters?


The biggest advantage of using fiberglass air filters is that they are inexpensive when compared to more advanced filters like pleated filters or whole house air cleaners. You can typically buy an individual fiberglass filter for under $3, and you can find them at almost any department, grocery or large retail store.


What are the disadvantages of fiberglass air filters?




    • Not effective at removing small particles. Fiberglass filters are only designed to remove the largest particles from your home’s air. That means that they provide a minimum amount of protection for your heating and cooling system, and they do very little to protect your health (see below).



If you have any questions about fiberglass air filters, or if you’d like a heating and cooling system serviced or installed in your home, contact Jerry Kelly, your St. Charles, MO, furnace and air conditioning contractor. We service the St. Louis area, including towns like Weldon Spring, Wentzville and Winghaven, MO.
