The Importance of Regularly Changing Your Air Filter

Your air filter is responsible for trapping airborne particles and keeping your home's air clean and healthy. But when it becomes dirty and clogged, it can no longer function effectively, and the quality of your indoor air can suffer. That's why it's essential to regularly change your air filter.

Here are some of the top reasons why changing your air filter is so important:

1. Improved Indoor Air Quality

When your air filter is clean, it can effectively remove pollutants like dust, pollen, pet dander, and other harmful particles from your home's air. But as it becomes clogged, it can no longer capture these contaminants, and they can circulate through your home, leading to poor indoor air quality and potential health problems.

2. Increased HVAC Efficiency

A dirty air filter can reduce the efficiency of your HVAC system, making it work harder and use more energy to heat or cool your home. By regularly changing your air filter, you can help your HVAC system operate smoothly and efficiently, reducing energy consumption and saving you money on your utility bills.

Air filters are an important, yet often overlooked component of your home's HVAC system. They may look like simple cardboard boxes full of fibers, but they play a huge role in indoor air quality and HVAC performance. Here's a quick look at what these filters do and why they are so essential.

Air filters are made up of spun fiberglass, paper, or cloth enclosed in a cardboard frame. Their purpose is to clean the air that circulates through the HVAC system, trapping and holding dust, dirt, pollen, mold, lint, fibers, and other contaminants. Then, when the air is sent back through the HVAC system after it's been conditioned, the filter removes these particles from the air.

Every single bit of air that heats or cools your home will pass through the air filter, so it's critical that it's always clean. A dirty, clogged filter can cause a number of problems, from reduced airflow to HVAC system damage to higher energy bills. That's why it's important to check and replace your air filters every month. 

Simply hold the filter up to a light source - if you can't see the light through it, it's time for a new one.

Absolutely! Indoor air quality can vary from home to home, but most of us spend around 90% of our time indoors, making it essential to ensure the air in our homes is clean. Pollutants such as particulate matter, formaldehyde, mold, and pollen are all common indoor contaminants.

So, what's the best way to improve the air inside your house? Reducing or removing pollutant sources and ventilating with clean outdoor air are the most effective strategies. However, air filtration can also be used to supplement these measures. Portable air cleaners and HVAC filters can both be used to reduce indoor air pollution and improve air quality.

These devices are designed to filter air in either a single room or throughout the entire house. While they are very useful in removing pollutants from the air, they cannot completely clear it of all contaminants. So, if you're looking to breathe easier, investing in a portable air cleaner and/or upgrading the air filter in your existing HVAC system is a great place to start!

Do you know where to locate air filters in your house? If you have a forced air heating or cooling system, then it's likely that your home has at least one air filter. This filter works to get rid of any airborne particles or debris from the air inside your home. To enjoy better indoor air quality, it's advised to replace your air filter every three months. Though, if your home has numerous occupants or pets, you should check your filter at least once a month. When you can't see through it anymore, it's time for a new one. When replacing your air filter, make sure to use the same model number as the one you just took out.

When you want to find the air handler, you'll need to look for a one to four-inch slot. It should either be covered by a removable lid or a wide-hinged lid. Once you open the lid, you should be able to spot the existing filter. Remove the old filter and insert the new one carefully - the filter should have arrows to help you make sure it's inserted correctly. The arrows should be pointing in the direction of the unit.

Homes with larger systems tend to have more than one air filter. After finding the first one at the air handler, you should see a second filter at the return vent. It will be larger than the regular vents and may either be rectangular or square. You may even find air filters in ceiling or floor return vents.
