Cleaner Air and Efficient HVAC Operation
The air we breathe is essential to our health and well-being. It is important to keep the air in our homes clean and free from pollutants. One way to ensure clean air in your home is to regularly clean your air filters. In this article, we will discuss the importance of cleaning air filters in your home and how it can benefit you and your family.
What are air filters?
Air filters are devices that are installed in heating, ventilation, and air conditioning (HVAC) systems to trap dust, dirt, and other pollutants. These filters help keep the air in your home clean by preventing these particles from circulating in the air.
Why is it important to clean air filters?
Over time, air filters become clogged with dirt and dust, reducing their effectiveness. A dirty air filter can cause your HVAC system to work harder than it needs to, leading to higher energy bills and potentially costly repairs. Moreover, dirty air filters can also negatively impact your health.
Health benefits of clean air filters
Clean air filters can help improve the air quality in your home, which is particularly important for people who suffer from allergies, asthma, or other respiratory conditions. Dust and other pollutants can aggravate these conditions, leading to symptoms such as coughing, sneezing, and difficulty breathing.
In addition, clean air filters can also reduce the risk of illnesses caused by bacteria and viruses. When air filters are dirty, they can become breeding grounds for these microorganisms, which can then circulate in the air and potentially cause illness.
How often should you change air filters?
The frequency with which you should change your air filters depends on several factors, including the type of filter you have, the level of pollutants in your home, and how often you use your HVAC system. As a general rule, it is recommended to change your air filters at least once every three months. However, if you have pets, smoke, or live in an area with high levels of pollution, you may need to change your filters more frequently.
What are MERV ratings?
MERV (Minimum Efficiency Reporting Value) ratings are used to measure the effectiveness of air filters in removing particles from the air. MERV ratings range from 1 to 20 and measure the ability of an air filter to capture particles of different sizes. A higher MERV rating means that the filter is able to capture smaller particles and more of them. The higher the MERV rating, the more effective the filter is at removing particles. The average
MERV ratings explained
- MERV 1-4: These are low-efficiency filters that are typically used in residential settings to protect the HVAC system from larger particles such as dust and pollen.
- MERV 5-8: These filters are capable of capturing smaller particles such as mold spores and pet dander. They are commonly used in residential settings, but may not be effective for those with allergies or respiratory conditions.
- MERV 9-12: These filters are capable of capturing even smaller particles such as lead dust and milled flour. They are commonly used in commercial and industrial settings, but can also be used in residential settings for those with allergies or respiratory conditions.
- MERV 13-16: These filters are highly efficient and can capture particles as small as bacteria and tobacco smoke. They are commonly used in hospitals and other medical settings, as well as in residential settings for those with severe allergies or respiratory conditions.
- MERV 17-20: These filters are extremely efficient and can capture particles as small as viruses. They are typically used in clean rooms and other specialized settings.
Choosing the right MERV rating
When choosing an air filter, it is important to consider your specific needs. For most residential settings, a MERV rating of 8-13 is sufficient. However, if you or someone in your household has allergies or respiratory conditions, a higher MERV rating may be necessary. It is important to note that higher MERV rated filters may also restrict airflow, leading to higher energy bills and potentially costly HVAC repairs.
Should I just get the highest MERV rating?
No. Like trying to breathe through a straw, having a higher MERV rating means having a higher restriction level. The higher the MERV rating, the harder your HVAC equipment will to work. Our inspectors change out their air filters to highest MERV ratings only during times when there is smoke in the air or pollen counts are high. Higher MERV rated filters may restrict airflow, leading to higher energy bills and potentially costly HVAC repairs.
Conclusion
Cleaning your air filters is a simple and cost-effective way to improve the air quality in your home and protect your health. By regularly cleaning your filters, you can reduce the risk of allergies, respiratory conditions, and illnesses caused by bacteria and viruses. So, make sure to add this task to your regular home maintenance routine and breathe easier knowing you have clean air in your home.
