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
  • Anyone interested in having and maintaining a clean indoor air standard

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.
