The Best Filters for Furnace: A Comprehensive Guide

When it comes to furnaces, the right filter can make all the difference. From disposable electrostatic filters to HEPA filters, there are a variety of options available to suit your needs. But with so many choices, it can be difficult to know which one is best for your furnace. In this comprehensive guide, we'll explore the different types of furnace filters, their features, and how to choose the right one for your home. A disposable electrostatic filter is a great option for homes with children, pets, or smokers.

These filters contain self-charging electrostatic cotton or paper fibers that attract and trap small particles. With a MERV rating of 10, these filters are affordable in standard sizes and are a good solution for most residential ovens. However, custom sizes can be expensive if replaced regularly over several years. HEPA filters are dense and can reduce the airflow entering the oven, so they are generally used only in commercial ovens or hospitals. With a MERV rating of 16-20, they block the highest level of particles in the air and provide better air quality.

However, they are not suitable for most residential ovens. Oven filters come in dozens of sizes, with the three most common sizes being 16 by 20 inches, 20 by 25 inches and 16 by 25 inches. The thickness of the filter varies from one to five inches, and in general, the thicker the filter, the more particle blocking capacity it will have. Before choosing a filter, you will need to consult the owner's manual or operating manual as not all ovens accept a thicker product. As the filter becomes thicker, the oven must work harder to draw air through it, reducing its efficiency and service life.
