If you’re like most people, you probably don’t think too much about your air filter.

Air filters for your HVAC system play an important role in protecting your furnace or air conditioner and keeping the air in your home clean. Depending on the type of filter you have and the conditions in your home, you should change your filter at least every three months.
The Importance of Changing Your Air Filter
An air filter for your home’s forced air heating and cooling system is important for several reasons. The main purpose of the filter is to protect the inside of your HVAC system from dirt and dust buildup, which can damage the system over time. A clean filter also helps your system run more efficiently, which can save you money on your energy bill. You should check your air filter every month and change it if it looks dirty. If you have pets or someone in your home who suffers from allergies, you may need to change the filter more often. Some filters are designed to be washed and reused, while others need to be replaced each month. If you’re not sure how often to change your air filter or what type of filter you need, consult your HVAC professional.
How Often to Change Your Air Filter
You should check your air filter every month and change it when it’s dirty. If you have pets or someone in your home suffers from allergies, you may need to change it more often. Some filters can be cleaned and reused, but others need to be replaced. If your air filter is dirty, your furnace or air conditioner will have to work harder to move air through the system, which can waste energy and increase your utility bills. A dirty air filter can also cause your furnace or air conditioner to overheat and break down prematurely.
Signs That It’s Time to Change Your Air Filter
The air filter in your HVAC unit is an important part of keeping your home’s air quality clean. Depending on the type of filter you have, it should be changed every one to three months. However, there are some signs that you may need to change it more frequently. If you notice any of the following, it’s time to replace your air filter. 1. Your energy bills have increased significantly. 2. Your HVAC unit is making more noise than usual. 3. The airflow in your home is not as strong as it used to be. 4. You can see dirt and dust on your furniture and floors more often than usual. 5. You or someone in your family has been coughing or sneezing more than normal. If you notice any of these signs, don’t hesitate to change your air filter right away
The Different Types of Air Filters
Not all air filters are created equal. In fact, there are several different types of air filters that are designed for different purposes. Choosing the right air filter for your home or business is important in order to keep the air quality high and to prevent any damage to your HVAC system. The first type of air filter is the mechanical air filter. This type of air filter works by trapping particles in the mesh or webbing material that makes up the filter. The mesh or webbing is usually made out of natural fibers like cotton or polyester. Mechanical air filters are great at trapping large particles, but they do not work well at trapping smaller particles like viruses and bacteria. The second type of air filter is the activated carbon air filter. This type of air filter uses a process called adsorption to remove particles from the air. Adsorption is when a gas or liquid clings to the surface of another material. Activated carbon air filters have a very large surface area, which allows them to adsorb more particles than other types of filters. The only downside to activated carbon filters is that they need to be replaced more often than other types of filters because they can become full quickly. The third type of air filter is the electrostatic air filter. This type of air filter uses static electricity to attract and trap particles in the filter material. Electrostatic filters usually have a Lifetime Air Filters metal charged grid that helps to attract and trap particles in the filter material. The only downside to electrostatic filters is that they can require more maintenance than other types of filters because the metal grid needs to be regularly cleaned in order to prevent it from becoming clogged with dust and dirt. The fourth type of air filter is the ultraviolet (UV) germicidal air filter. This type of filter uses UV light to kill bacteria and viruses in theair. UV germicidal filters are great at removing small particulates like viruses and bacteria, but they do not work well at trapping larger particulates like dust and pollen.
How to Change Your Air Filter
It’s important to regularly change your air filter to ensure that your furnace or air conditioner is running properly and efficiently. A dirty air filter can restrict airflow, causing your system to work harder and use more energy. Most filters should be changed at least once every three months, but you may need to change them more often if you have pets or live in a dusty area. Some filters can be cleaned and reused, while others need to be replaced. Be sure to check your manufacturer’s recommendations before replacing or cleaning your filter.
The Bottom Line
We recommend that you change your air filter at least every 3 months — more often if you have pets or live in a dusty area. If you have allergies, you may want to change your filter even more frequently.

A clean air filter helps your HVAC system run more efficiently and prevents premature wear on your system. Over time, dirt and dust can build up on your air filter and restrict airflow to your furnace or air conditioner. This makes your system work harder to heat or cool your home, which can lead to expensive repairs in the future.
How often you need to change your HVAC air filter depends on a few factors, including the type of filter you have, the season, and the amount of pollutants in your home. Check out our list of resources below to learn more about changing your air filters. Type of Filter The type of filter you have in your HVAC system will affect how often you need to change it. Disposable pleated filters should be changed every 1-3 months, while reusable electrostatic filters can last up to a year before needing to be cleaned. Season The season also plays a role in how often you should change your air filters. In the spring and summer, when pollen and dust levels are higher, you may need to change your filters more frequently. In the fall and winter, when there are fewer airborne pollutants, you can change your filters less often. Amount of Pollutants in Your Home If you or someone in your home has allergies or asthma, you may need to change your air filters more frequently to prevent triggering an attack. Similarly, if you have pets that shed fur or breed chickens indoors, you may need to change your filters more often to keep the air quality high in your home.
