How often to change HVAC filter

How often to change your HVAC filter depends on several factors. One important factor is the type of filter you have. Different filters have different recommended lifespans. For example, fiberglass filters typically need to be replaced every 30 days, while pleated filters can last up to 90 days.

In general, it is recommended by most air filter manufacturers and HVAC companies to change your air filter every 90 days, which is equivalent to 3 months.

How Often to Change Home Air Filters

The frequency at which you should change your home air filters depends on various factors, including the type of filter, household conditions, and personal health considerations. As a general guideline, it is recommended to change your air filters every 1 to 3 months. However, this can vary based on individual circumstances.

These filters tend to accumulate dust and debris more quickly. On the other hand, higher-quality pleated filters can last up to 90 days before needing replacement.

Does anyone in your house have allergies and/or asthma?

If anyone in your household suffers from allergies and/or asthma, it is even more crucial to pay attention to the frequency of changing your HVAC filters. Allergens and irritants in the air can exacerbate symptoms and affect the respiratory health of individuals with these conditions.

Do you have any pets?

If you have pets, it is important to change your HVAC filter more frequently, typically every 1 to 3 months, to keep your system clean and efficient. Pet hair and dander can quickly accumulate in the filter, potentially leading to clogs and decreased performance. Regular filter changes help ensure clean and healthy air for both you and your furry friends.

Do you have younger children?

If there are young children in your home, it’s important to change your HVAC filter more frequently to ensure a healthy indoor environment.

Things That Can Affect the Lifespan of your HVAC Air Filter:

How often you use your heating and cooling system

The frequency of your heating and cooling system usage impacts how often you should change your HVAC air filter. The more you use your system, the quicker the filter accumulates debris. For optimal performance and air quality, it’s advisable to monitor the filter’s condition regularly and replace it accordingly.

The size of your house

House size matters. Larger homes often have bigger HVAC systems that require more air circulation. Consequently, the air filter may get dirty more quickly, necessitating more frequent replacements. Regularly monitor and inspect the filter’s condition to ensure optimal airflow and system efficiency.

The air quality in your home

The air quality in your home affects the frequency of HVAC filter changes. Factors such as high dust levels, pollen, pets, and smokers can lead to faster clogging. Regularly check and replace the filter to ensure good indoor air quality and maintain the efficiency of your HVAC system.

How to Tell When You Need to Change Your HVAC Air Filter

To determine when you need to change your HVAC air filter, pay attention to certain signs. First, check the manufacturer’s recommendations for the specific filter type and system. However, some common indicators include reduced airflow, visible dirt or debris on the filter, increased dust accumulation in your home, and unusual odors coming from the vents. Additionally, if you or your family members experience increased allergies or respiratory issues, it may be a sign that the filter needs changing more frequently. Regular inspection and monitoring of these factors will help you determine the appropriate timing for changing your HVAC air filter.
