The Benefits of Home Air Filters: Why You Should Change Yours Regularly

An air cleaner is an essential part of a healthy HVAC system. This lightweight barrier prevents dust, allergens, and other debris from entering the air you breathe. At its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system. Not only does this improve the air quality inside your home, but it also protects your HVAC system from potential damage. 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 are generally inexpensive and changing the air filter is a simple task that does not require a professional hand. Dusty hearth: Whether from a recent home construction project or simply from dust accumulated in little-used rooms, anything that doesn't vacuum has a chance of ending up in the filter. As the filter increasingly traps natural pollution from particles in your home: dust, mold and fungal spores, pet dander, fabric fibers, etc.

The air filter works hard to minimize dust levels in the indoor air you breathe by preventing dust and debris from accumulating on the mechanical parts of your heating and air conditioning system. MERV stands for “minimum efficiency information value” and the MERV rating is a measure of how effectively a filter removes particles from the air passing through it. The air filter traps dust and dirt particles before they can reach and accumulate on the unit's internal and moving components. Failure to clean and replace the air filter on a regular basis is essentially a problem for the environment. No matter the size difference or the types available, all air filters are designed to meet these primary objectives.

All Temperature Air recommends that you change your air filter regularly to keep your home and HVAC system running smoothly. The filter prevents dirt, dust and pet hair from entering the air ducts and returning to the house, reducing air quality. If you don't change the air filters in your home, you increase the risk of your home getting sick. If you keep your air filter clean and in good condition with regular maintenance, you could save up to 15% in utility costs. Pleated filters trap and retain several grams of dust, preventing it from seeping through the duct and inevitably settling on the surfaces of your home. Compared to other DIY home improvement projects, changing air filters is a quick and painless process that can be done in less than an hour.

The Benefits of Home Air Filters

Home air filters are essential for maintaining good indoor air quality.

They help reduce allergens such as pollen, pet dander, mold spores, smoke particles, and other airborne contaminants that can cause health problems. By trapping these particles before they enter your home’s ventilation system, they help keep your family safe from respiratory illnesses. In addition to improving indoor air quality, regularly changing your home’s air filters can also help reduce energy costs. Dirty filters restrict airflow which can cause your HVAC system to work harder than necessary to maintain comfortable temperatures in your home. This can lead to higher energy bills as well as increased wear-and-tear on your HVAC system.

How Often Should You Change Your Home Air Filters?

The frequency with which you should change your home’s air filters depends on several factors including how often you use your HVAC system, how many pets you have in your home, and whether anyone in your household suffers from allergies or asthma. In general, it’s recommended that you change your home’s air filters every three months or so.

If you have pets or someone in your household suffers from allergies or asthma, it’s best to change them more frequently – every one to two months – to ensure optimal indoor air quality.
