Air Filters for Furnace
Your home’s furnace works by having air pumped inside and heated before redistribution. The newly heated air travels through your homes duct system before entering the various rooms of your home. The furnace heats the air until it matches the number of a thermostat and the smooth airflow ensures that there is no dip in temperature. However, the air is not cleansed free of outside pollutants and allergens by this process alone.
The air filters for a furnace are the tools used to clean the air, leaving a furnace before it enters your home. Situated behind the blower fan, the filter traps and absorbs airborne particles before they become an issue. Effective furnace filters protect your home, but they lose effectiveness over time and need maintenance.
Furnace Filter Replacement
A furnace filter keeps indoor air quality up while keeping outside contaminants and allergens out. The air cleansing process leaves the airflow entering the blowing fan cleaner but the filter dirtier. The filter will eventually become covered in so much dirt and debris that the airflow going through it becomes disrupted. A dirty filter brings problems that affect both an air system and your home’s billing.
When a furnace filter is dirty, this leads to problems with the airflow that in turn affect the air coming into your home. When a dirty filter blocks airflow, the result is a slow down or even stopping of the air. Stopped airflow leads to stagnant, dry air in your home and since the heated air is not traveling there will be temperature fluctuations. The dips in air quality become more noticeable over time along with the increase in your home billing.
When an air system encounters a blockage, then the natural reaction for it is to attempt to go past it. The air system will increase the electricity used in an attempted bypass causing a spike in home energy usage. When your home’s electrical systems are overburdened, it also sees increased energy billing at the end of the month. You may end up experiencing costs that are avoidable by replacing the old filters.
Replacing the Filter
Your air filters will need periodic replacement, the time frame of which depends on varying factors. The area around your home plays a large part in filter effectiveness. Areas with high levels of allergens and pollutants cause the filter to become dirty faster due to the constant filtration needed. The MERV rating of a filter need consideration when making a replacement schedule.
Minimum Efficiency Reporting Value (MERV) ratings are the calculated efficiency values of a filter. Furnace filters consist of a mesh weave designed to trap and absorb airborne irritants coming through the air system. The furnace filters MERV rating is dependent on the tightness of its weaving. Home furnace filters have more centered ratings in order to avoid the filter mesh weaves from being too tight and affecting airflow.

Best Furnace Filters Review
Best Furnace Filters Overview
The best air furnace filters have a MERV rating of 8 to 13. MERV means Minimum Efficiency Reporting Value and refers to how effective the filter is at trapping harmful particulates. The higher the MERV rating the better.
However, most homes, apartments, and condominiums do not need a furnace filter with a MERV rating higher than 13. The reason is that the higher rated filters have smaller pores to filter out the particulates and that restricts the airflow, which in turn makes the furnace fan work harder. That can result in a higher energy bill and possibly a broken fan that will need replacing. A top rated furnace filter in the 8 to 13 range is more than adequate for the majority of homes.
Key Features of the Best Furnace Filters
The best rated furnace filters should be able to filter out the following substances:
- MERV 8 - Pollen
- MERV 8 - Dust
- MERV 8 - Dust mites
- MERV 8 - Pet dander
- MERV 8 to 11 - Mold spores
- MERV 8 to 11 - Exhaust fumes
- MERV 8 to 13 - Tobacco smoke
- MERV 8 to 13 - Smoke
- MERV 8 to 13 - Some bacteria
- MERV 8 to 13 - Droplet nuclei (droplets from a cough or a sneeze)
Performance of the Best Furnace Filters
The best air furnace filters will provide a clean and safe breathing environment for everyone living inside the home by maintaining indoor air quality of a very high standard. According to the EPA, the air inside a home can be more polluted than the air outside of it. A top rated furnace filter will keep the air inside a home clean and help to protect the respiratory health of everyone within.
The best furnace filters for allergies will help to prevent the spread of infection and reduce the attack of allergies by preventing the spread of allergens and pollutants. The best rated furnace filters will help reduce energy costs by using less energy to draw air through the HVAC system. Efficiency in filtering dangerous particulates and efficiency in energy consumption are the two main qualities to look for in the best home furnace filters.
Recommended Users of the Best Furnace Filters
- Households that have members with severe allergy problems
- Anyone who has recently welcomed a newborn baby into their life
- Anyone with an immune system compromised by illness
- Asthmatics who want to avoid any potential triggers to their condition

The Best Furnace Filters: Conclusion
The best furnace air filters will remove nearly all of the particulates that can cause infections and trigger allergic reactions in sensitive individuals. They will help to maintain a clean indoor air environment that is perfect for anyone with sensitive lungs and airways such as babies and the immunocompromised.
Regardless of the MERV rating, furnace filters should be cleaned and changed often so that they do not get clogged and their airflow does not get restricted. That will reduce their efficiency and negate any of the positive attributes of the best rated furnace filters.
