Benefits of Changing Your Furnace Filter Regularly
Regularly changing the furnace filter can provide numerous benefits to a home. One of the main advantages is improved airflow, which helps keep the air flow moving effectively through the vents and ducts in a house. This ensures that all rooms are receiving adequate amounts of heated or cooled air, depending on the temperature outside.
Additionally, regular filter changes can also help improve indoor air quality by trapping dust particles and other allergens before they can be circulated in a home. Furnace filters are designed to capture many airborne contaminants, such as pet dander, pollen, mold spores, smoke particles, and bacteria. By changing your furnace filter regularly, these pollutants are unable to get trapped in the HVAC system and circulate around the home, potentially causing health issues for occupants.
Furthermore, when replacing with new filters, it is important to choose one based on its MERV rating; this will determine how effective it will be at capturing small contaminants from entering your living environment.
The frequency that you should change your furnace filter depends on several factors, including whether you have pets or allergies in your household, as well as what type of filter is being used. If you don't have any pets or allergies, then generally speaking, most manufacturers recommend monthly changes during peak heating/cooling season, while others suggest every three months regardless of other factors present in a home environment.
In instances where there are multiple pets or people with severe allergies, then more frequent changes may be necessary; typically every 30 days instead of 90 days for optimal protection from harmful particles circulating through an HVAC system. It is important to remember that even if you do not have any pets, it is still beneficial to change out filters frequently, since they do become clogged over time due to dust accumulation trapped within them over time, which reduces their efficacy at filtering out unwanted particles from circulating throughout an area.
Replacing your furnace filter regularly is one of the easiest ways to ensure that your HVAC system runs efficiently and provides cleaner air quality throughout a living space while protecting those who occupy it from potential health issues caused by airborne contaminants, both large and small, getting circulated into living areas of a house due to inadequate filtration systems installed within them.
It is essential to follow manufacturer instructions regarding recommended changes, but generally speaking, it is best practice to replace them periodically - usually every 3 months - regardless if other factors such as allergies or pets are present, as dirty filters will decrease airflow efficiency, leading to higher energy bills over time, so proper maintenance should be performed accordingly.
Types of Furnace Filters
The selection of an appropriate furnace filter is critical to maintaining efficient, cost-effective operation of the heating system.
