How Do I Know What Kind of Furnace Filter Is Right for Me?

To choose which furnace filter is best for you, you must first comprehend a few fundamental concepts regarding the filters under consideration.


The furnace filter is essential in keeping your apartment’s air clean and comfortable for your household. The main function of a furnace filter is always to guard the compressor fan from all of the pollen, hairs, and other junk drawn in by the returning duct. Eliminating these pollutants protects critical parts in the furnace and enhances interior air quality.

The furnace filter is evaluated using the minimum efficiency report value (MERV). The minimal efficiency reporting value is used to grade furnace filters from 1 to 16. Dirt, pet hair or fur, mold spores and mildew, viruses, smoke and fumes, bacteria, and pollen can all be protected by furnace filters. Furnace filters aren’t spectacular but selecting the correct furnace filter for your requirements is critical to the airflow comfortability of your house.

What Are Furnace Filters?

Furnace filters are usually found in the furnace’s compressor chamber. The compartment is often positioned in a tray or door on the compressor section. The air compressor is usually positioned near the air entering vents in the center of your home. The primary function of your furnace filter is to keep your system safe. The filter also improves the interior air quality of your home, which benefits your breathing health.

How to Know What Kind of Furnace Filter Is Right for Me?

Filters for furnaces and air conditioners are not all made equal. Not all filters are perfect for all furnaces and homes. You can choose custom furnace filters according to your furnace filter sizes. There are also some important factors to consider when purchasing a furnace filter. To help you make informed decisions about which type of furnace filter is best for you, here’s a quick solution:

MERV Ratings: A MERV grade is important when choosing furnace filters. Since it specifies the type of air pollutants that the filter will collect, it is very efficient. If you or anyone you live with who has sensitivities, an inflammatory condition, or other health issues that your apartment’s air quality may impact, use furnace filters having greater MERV scores.

Fiberglass Filters: The fiberglass furnace filter is cheap and disposable. The filters capture up to 80% of pollutants with 50 microns or bigger and 25% with 3 to 10 microns in size. It also enables optimum ventilation in your system but does not filter out hazardous particles that might create long-term health concerns.

Pleated Filters: The most popular furnace filter used in households is disposable pleated filters. Pleated filters are thicker than fiberglass filters and have a wavy shape that increases surface area to catch extra dust. They have better MERV scores and are more cost-efficient. Pleated furnace filters are the finest option for your system if you want low cost and good quality.

Electrostatic Filters: Electrostatic furnace filters are available in disposable and permanent configurations. They function by attracting particles from the air with self-charging natural fibers such as cotton or paper, somewhat like magnets. However, the diverse materials used to construct electrostatic filters may require your furnace to work more to move air.
