Why it’s Important to Regularly Change Your HVAC Air Filters The HVAC system in your home’s furnace, heat pump, or air conditioner includes an essential but frequently disregarded component: the air filter. Air filters have a significant impact on several important aspects of HVAC equipment efficiency and interior comfort. Apparently, air filters are enormous cardboard boxes filled with fibers or pleated material. Here’s a quick overview of air filters by the experts at Conejo Valley Home Services and why these parts are so important to the cooling and heating systems in your house.

What are HVAC Air Filters and What Do They Do?

HVAC filters are crucial for the proper operation and equipment longevity, for protecting indoor air quality in the homes, and for the occupants’ health. Changing your air filter is one of the well-known aspects of routine HVAC maintenance. A vast range of pollutants, including dust, dirt, dander, pollen, mold spores, hair, fibers, and much more, are present in normal air. Air filters remove pollutants to safeguard the HVAC system as these particles can prevent it from operating efficiently. To increase the surface area for collecting particles, manufacturers make filters with pleated material. Many air filters have built-in layers to trap particulate matter. Other choices include electrostatic filters, fiberglass filters, and HEPA filters.

How Do HVAC Air Filters Work?

Typically, an air filter is constructed from pleated paper or cloth, spun fiberglass material, and a cardboard frame. The primary function air filter is to clean the air that passes through your HVAC system. Filters capture and retain a wide range of pollutants and particulates, including:
  • Dirt and dust
  • Mold spores
  • Pollen
  • Lint and fiber
  • Tiny plaster, Metal, or wood particles
  • Microorganisms and bacteria
  • Animal fur or hair
Filtration often happens when used air is returned to the HVAC system for conditioning and redistribution. Filter material eliminates particles and other impurities from the air as it is driven through it. Thus, your HVAC system must have a clean air filter to function properly.

Knowing Your Filter Efficiency

Minimum Efficiency Reporting Value or MERV is used to gauge the air filter efficiency of the HVAC. This offers a consistent metric for assessing the effectiveness and performance of HVAC filters. The MERV rating scale typically ranges from 1 on the low end to 16 on the high end. The higher the MERV rating, which is typically at 16, the better the filter is at absorbing pollutants floating in the air. You may find some filters with higher ratings. If you’re looking for an HVAC air filter for a commercial building, choose the one with a higher MERV rating to get a better filtration level. The higher filtration level you require dictates the MERV rating you should get when choosing HVAC air filters for your office. You need to understand the filter efficiency of your HVAC’s air filter for improving air quality.

Importance of Replacing Your HVAC Filters

Wondering what happens when your HVAC filter doesn’t work? The filter collects dust and debris. The filthy filter lowers airflow and makes your heating and cooling system work harder. You have to spend more money because the filter consumes more energy. Additionally, it fails to maintain the ideal temperature in your house. This needs air filters to operate for a longer time, taxing the system. That means if you’re buying HVAC for allergy relief, make sure to check the efficiency of its air filter.

Benefits of Regular HVAC Air Filter Maintenance

» Improve Home Air Quality

Your home’s air quality is directly impacted by how clean the air filter of your heating and cooling system is. In actuality, the air filter’s main function is to clean the air that passes via this system. The air filter is built with fibers, typically composed of fiberglass, that capture the polluting substances present in the air in your home. These can contain bacteria, microbes, animal fur, dirt dust, pollen, and more. Impure or dirty air in the home isn’t the only effect of filthy filters. Unclean air filters can leave undesirable particles in the HVAC system. Replacing the air filter regularly allows the air to be cleaned more thoroughly. It removes the dirt and bacteria accumulated inside the filter. Furthermore, individuals typically spend around 90% of their time indoors. That means air quality inside the buildings is generally poorer compared to outside air quality. Health problems including allergies, asthma, headaches, and long-term illnesses like cardiovascular disease can result from breathing in polluted and contaminated air. That is why changing your air filters frequently is important to ensure that your family is breathing clean air.
