Choosing the Right Air Filter 16x20x1 for Your HVAC System

When it comes to selecting an air filter 16x20x1 for your HVAC system, there are a few important factors to consider. These filters have a good density that allows them to capture small dust particles and air pollutants such as pollen, mold spores, pet dander, and more. The thickness of the filter can range from 1 to 5 inches deep, with some options being more common than others. A 1-inch filter with less surface area will clog up quickly and need to be replaced more often than a coarser filter.

Outdoor air quality can also influence how often the air filter needs to be changed. Pleated air filters are more expensive initially, but they are more effective at trapping particles and can last up to 90 days depending on usage. To make sure you get the right size, remove the existing filter and measure it. The MERV rating is designed to provide a balance between particulate filtering and energy efficiency.

To determine how often your air filter should be changed, visually inspect it every month. When selecting an air filter 16x20x1 for your HVAC system, you should take into account the size, how often you want to change it, and the MERV rating. Fiberglass air filters are more affordable but less efficient at capturing dust and particles from the air. If you have young children at home, it's best to use high-quality pleated air filters and change them every two months.
