How Do I Know Which Furnace Filter to Buy?
Consider the MERV rating, which indicates the filter’s ability to trap particles. A higher MERV rating means better filtration. However, ensure your furnace can handle the airflow restriction of higher-rated filters.
Can a Dirty Furnace Filter Cause Health Problems?
Yes, a dirty filter can lead to poor indoor air quality, which may exacerbate allergies and respiratory issues. It allows dust, mold spores, and other pollutants to circulate in your home.
What Happens if You Don’t Change Your Furnace Filter?
Neglecting to change your filter can lead to reduced efficiency, higher energy costs, and potential damage to the furnace. It may also cause the system to overheat and shut down.
Are Reusable Furnace Filters Effective?
Reusable filters, like electrostatic ones, can be effective if cleaned regularly. They are environmentally friendly and can save money over time, but require maintenance to ensure performance.
How Does Changing the Furnace Filter Affect Energy Efficiency?
A clean filter allows the furnace to operate at its optimal efficiency, reducing energy consumption. This can lower your heating bills and reduce the environmental impact of your home’s energy use.
