We created separate testing categories to ensure that we could accurately rate each furnace filter and narrow down the top choices. With our years of experience in performing tests on different types of products, we understand the necessary categories to use for a higher level of accuracy with our results. The top categories for the furnace filter tests include efficiency, durability, and application.
Efficiency: The efficiency and ease of use of each furnace filter allowed us to determine how well it worked when removing pollen and dirt in the air. We examined how well it operated and the results that it delivered, which determined its overall value.
Durability: The durability and construction of each filter was another consideration based on the quality of materials that are used to construct each product. The durability of the product influences how long it lasts and how well it filters the air after several months.
Application: Application is an additional category that determines how easy the filter is to install and if it’s an accurate size for each furnace. Filters that don’t have accurate sizes can operate poorly and can cause the panel to be difficult to close.
