Air quality is a major concern for many homeowners, and one of the best ways to improve it is by replacing air filters. Air filters are designed to trap particles that are invisible to the naked eye, such as dirt, dust, and pollen. An air cleaner is an essential component of a healthy HVAC system, as it prevents dust, allergens, and other debris from entering the air you breathe. It also helps extend the lifespan of your HVAC system and minimize the need for repairs. However, most people don't change their air filter as often as they should, which can lead to a number of problems.
By understanding the consequences of using a dirty air filter and how often you should replace it, you can save money and improve your comfort and health. Here are some tips from a leading HVAC company in Anaheim. Air filters live up to their name. Not only do they keep dust and pollen out, but they are also tasked with keeping larger particles out of your HVAC system and preventing them from being damaged. Dirty, unchanged filters are a major cause of problems with your HVAC system. Air filters work by passing air through a filter that will remove particles from the air.
They act like a strainer, capturing particles that you don't want to flow through your home. Air filtration is the process of separating dispersed particles from air using porous media. The filter fibers are expected to separate and retain particles on or within the filter media. An example of the use of air filtration is as a preventive measure to protect the respiratory systems of indoor human occupants, as well as HVAC equipment. This can be done by mechanical filtration to reduce contaminant concentrations, which vary depending on the nature of the application and location.
The success of any filtration system depends on its ability to capture the right contaminants in the right amount while presenting the least resistance to airflow. The air cleaner in your HVAC system is there to prevent dust and dirt from accumulating inside the air handler and duct system. As the air filter becomes clogged, it will increasingly restrict the flow of air through the system. A dirty air filter can even interfere with temperature sensors that tell the HVAC system to start or stop. One of the easiest ways to maintain your system and preserve its useful life is to use a properly fitted air filter and change it regularly. Clogged air filters can cause overheating, restricted airflow, and fouling the entire HVAC system.
Filters with higher MERV ratings generally have a denser filter material, which means more force is required to push air through the filter. Finally, the porosity of the filter undergoes a substantial change leading to premature clogging of the filter and a shorter service life. The air filter traps dust and dirt particles before they can reach and accumulate on the internal and moving components of the unit. Other challenges faced with filter performance include lack of flow uniformity upstream and downstream of pleated filters due to various media properties, cartridge design, and filter installation. This also provides your HVAC system with a protective barrier against dirt and debris; the primary and original reason for using the household air cleaner. Air that would move freely through a clean air filter is trapped behind a dirty one, creating a high energy demand on your HVAC system.

However, it is important to note that proper selection of the air cleaner is equally important to provide the operating conditions necessary to operate as designed. Changing your air filter regularly also keeps your heating system running at full capacity, which means lower utility bills. By understanding why it's important to replace your air filters, you can save money while improving your comfort and health.
