We have over 35 years of experience testing different types of products in a range of various industries, which has led us to create testing categories for more accuracy when narrowing down the top items we review. With the furnace filter 20-x-25-x-1, we created categories that include application, efficiency, and durability.
Application: The application of the furnace filter is an important category that allowed us to review how easy the product was to install in the appliance. We examined the size and if it was accurate with the description on the packaging to determine if it fit securely or was loose.
Efficiency: The efficiency of each furnace filter was an additional category that allowed us to determine the results that were delivered. We examined each filter to determine how many particles, dander, and smoke was collected before it needed to be replaced.
Durability: The construction and durability of each filter was an additional factor we reviewed to determine if it could hold up well to frequent use without falling apart. We examined the quality of the materials to ensure that it was worth its price tag and had more value compared to other filters in the industry.
