In general, most air filter manufacturers and HVAC companies suggest changing the air filter every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment. The only way to be sure how often the air filter needs to be changed is to perform a visual inspection of the filter every month. After a few months, you'll get an idea of how quickly it gets dirty.
You may need to re-evaluate if you're having a new pet or if the outside air quality has been poor.
A general rule for pleated air filters
(such as those manufactured by FilterBuy) is to change them every 90 days. As the filter traps more dirt, dust and allergens from the air, its efficiency decreases. Find out below if you should replace the filter more often.Changing the air filters in your air conditioning system is an essential practice that ensures that clean air circulates throughout the house. As a general rule, lower home occupancy extends the life of an air cleaner, while higher home occupancy reduces it. The deeper the folds, the greater the surface area of the filter and the more space it has to collect airborne particles, so it may not clog as quickly as a flat filter. They also generate less air resistance, which can help the HVAC system work more effectively and reduce wear and tear on components, including the fan motor. A number of factors must be considered when deciding how often an oven filter should be changed, and many filter manufacturers recommend how often their product should be replaced.
Estimating how often an air filter should be changed can be complicated because of the many different variables involved. During periods of the year when HVAC equipment is operating frequently, air circulates more times around the house compared to times when the HVAC system is used sparingly. Air filters help clean the air in a heating and air conditioning system by removing unwanted dirt. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home. However, if replacing the air filter is simply out of the question for an extended period, going longer than 90 days won't cause irreparable damage to your air conditioning system.
Consider all factors mentioned above to determine a replacement program and decide what type and quality of filter you should use.

, changing the filter has several impacts on the HVAC system's ability to cool the house and on overall air quality. A typical manufacturer recommends replacing air filters every 30 to 90 days; however, this depends on the life of the filter and other household environmental factors. While a filter with a higher MERV rating should last longer, it can also restrict airflow in your home. However, many homeowners are unaware of how often air filters need to be replaced, making their system vulnerable to damage. For every dog that has a shed of hair, expect to replace the filter a month earlier than you would with a pet-free home. It's important to understand that air filters need to be replaced regularly.This helps keep your HVAC system running efficiently and ensures that clean air circulates throughout your home. The frequency of replacement depends on several factors such as location, pet ownership, age of system and equipment, and outside air quality. Generally speaking, pleated filters should be changed every 90 days or 3 months. However, it's best to perform a visual inspection every month so you can get an idea of how quickly it gets dirty.
If you have pets or live in an area with poor outside air quality, you may need to replace your filters more often than recommended. When deciding how often an oven filter should be changed, consider all factors mentioned above and decide what type and quality of filter you should use. A higher MERV rating will last longer but can also restrict airflow in your home. Make sure you understand how often your air filters need to be replaced in order to keep your HVAC system running efficiently and ensure that clean air circulates throughout your home.
