Find the Right 3 Inch Furnace Filter For Your HVAC System

Choosing the right 3 inch furnace filter is essential to ensure you’re successfully maintaining your HVAC system and indoor air quality. 

United Filter is a premier manufacturer of quality HVAC air filters with a wide range of popular 3 inch furnace filters. 

From basic, economy-style 3 inch filters to high-performance versions that capture even more dust and allergens, there are affordable solutions you can rely on.

Our 3-inch furnace filters are designed to capture an extensive range of air pollutants, including dust, pollen, pet dander, smoke, and more. By using our furnace filters, you can breathe easily in your home or commercial space. 

A 3-inch air filter should be replaced regularly. It is one of the simplest but most impactful steps to save on energy costs due to improved flow while increasing the lifespan of your furnace and HVAC system. 

The frequency of changing a 3 inch furnace filter depends on how often your heating and cooling system is used. Also, the kind of filter you use and other environmental factors, such as the dust and allergens that are present in your area. For example, it is best to replace your 3 inch furnace filter every 1-3 months.

Ensure You Know the Size of Your 3 Inch Furnace Filter

Since there are a number of different 3 inch filter sizes out there, we highly recommend that you be sure to measure your existing filter to choose the correct size that fits your system. 

Our 3-inch furnace filters are available at the most common lengths, widths, and depths to make sure you receive the correct replacement. To find the exact length, width, and depth your filter needs to fit correctly and operate efficiently, check what is printed on your current filter. 

Alternatively, you can measure the opening where it is installed. Confirming the correct 3 inch furnace filter side that you need ensures a leak-free, airtight fit, providing optimal airflow and inlet filtration efficiency.
