How Do HVAC Filters Work?
HVAC filters are integral to any heating, ventilation, and air conditioning system. They are designed to trap airborne particles such as dust, pollen, mold spores, and other allergens that can harm your health. By trapping these particles, HVAC filters help clean the air inside your home or office and improve the quality of your indoor environment. Regularly changing your HVAC filter is essential to ensure it continues to protect your indoor air quality adequately.
We will explain how HVAC filters work and why you should maintain them.
What Is an HVAC Filter?
An HVAC filter is a device used in heating, ventilation, and air conditioning systems to remove airborne particles from the air. These filters are typically made out of pleated paper or synthetic material and can be installed in commercial and residential settings. The purpose of an HVAC filter is to trap dust, pollen, dirt, and other airborne particles that can cause health problems or reduce air quality.
How Do HVAC Filters Work?
HVAC filters trap larger particles and block them from entering the system while allowing smaller particles to pass through. When air is drawn into the system, it passes through the filter where the larger particles, such as dust and pollen, are trapped. This helps keep the air clean and free from allergens, bacteria, and other contaminants.
MERV, or Minimum Efficiency Reporting Value rating, is used to measure the effectiveness of an air filter. The higher the MERV rating, the more efficient the filter and better it is at trapping smaller particles.
Benefits of Regularly Replacing HVAC Filters
Regularly replacing your HVAC filter is essential to maintaining a healthy and efficient system. Here are the benefits of regularly changing your filter:
1. Cleaner Air
A furnace filter helps clean the air from your HVAC system by trapping the microscopic particles, such as dust and pollen, that may cause allergic reactions. Regularly replacing the filter will ensure that the air inside your home or business is as clean as possible.
2. Improved Airflow
A clogged filter will reduce airflow over the evaporator coils, making it harder for your HVAC system to perform its job efficiently. A clean filter will allow more air and maximize performance, leading to improved cooling or heating and lower energy bills.
Some reasons for a clogged filter include dust, pet hair and dander, smoke particles, and other airborne contaminants. The best way to ensure improved air flow is to clean or replace your air filters regularly.
If you have a disposable filter that can be reused several times before needing to be replaced, clean it regularly as the manufacturer recommends.
3. Better Air Quality
Air filters improve air quality inside a home, business, or other space. Tapping dirt, dust, and other particulates out of the air, these filters help eliminate airborne contaminants from circulating throughout a building. This can help reduce allergies and asthma symptoms for those living in the space and ensure that any heating and cooling systems remain clean and in working order.
4. Reduced Energy Costs
Air filters also reduce energy costs for a space by keeping air flowing freely. When air can pass through the filter without impediment, it allows for greater efficiency from a heating or cooling system - resulting in less energy consumed overall.
