How often to change pleated air filters

Pleated air filters are an essential component of your HVAC system, ensuring that the air you breathe is clean and free from pollutants. However, many people are unsure about how often they should change their pleated air filters. In this article, we will discuss what pleated air filters are, the factors that affect how often they should be changed, and provide some tips for changing them.

What is a pleated air filter?

A pleated air filter is a type of air filter that is made of a synthetic or cotton material, pleated to increase the surface area and capture more contaminants. These filters are more efficient than traditional flat filters and can trap smaller particles, including dust, pollen, pet dander, and mold spores. Pleated air filters are available in various MERV (Minimum Efficiency Reporting Value) ratings, with higher ratings indicating better filtration performance.

Factors that affect how often to change your pleated air filter:

Several factors can influence the frequency of changing your pleated air filter. These include:

• Household size: A larger household generates more dust and dirt, which can clog the air filter more quickly.

• Presence of pets: Pets shed dander and hair, which can accumulate in the air filter and reduce its efficiency.

• Air quality: If you live in an area with poor air quality, your pleated air filter may need to be changed more frequently.

• MERV rating: Higher MERV-rated pleated air filters can capture more contaminants but may also need to be replaced more often.

• System usage: If your HVAC system is used frequently, the air filter will need to be changed more often.

How often to change your pleated air filter:

The general recommendation for changing pleated air filters is every 90 days or more frequently, depending on the factors mentioned above. However, this is just a guideline, and you may need to adjust the replacement frequency based on your specific circumstances. Here are some suggestions:

1. For a standard household without pets: Change the pleated air filter every 90 days.

2. For households with one pet: Change the filter every 60 days.

3. For households with multiple pets or people with allergies: Change the filter every 30-45 days.

4. For high-traffic areas or areas with poor air quality: Change the filter every 60 days.

Tips for changing your pleated air filter:

Changing your pleated air filter is a straightforward process. Here are some tips to make it easier:

1. Purchase the correct size: Before buying a new pleated air filter, measure the dimensions of your existing filter or check your HVAC system’s manual for the recommended size.

2. Turn off the HVAC system: Before replacing the filter, turn off the HVAC system to ensure safety.

3. Remove the old filter: Carefully remove the old filter from its housing, taking note of the direction of the airflow arrow.

4. Insert the new filter: Insert the new pleated air filter into the housing, making sure the airflow arrow points in the same direction as the old filter.

5. Set a reminder: To avoid forgetting to change your pleated air filter, set a reminder on your phone or calendar.

Conclusion:

Replacing your pleated air filter regularly is crucial for maintaining a clean and healthy indoor environment. By considering the factors that affect replacement frequency and following the tips provided, you can ensure that your HVAC system operates efficiently and effectively. Remember to check your pleated air filter monthly and replace it as needed to enjoy clean, fresh air in your home.
