How Often Do You Need an Air Filter Replacement?

Do you find yourself worrying about dirty filters or wondering if yours is time for a change?

An air filter replacement can be tricky if you don’t know what to look for. After all, filters perform different duties, and their lifespan depends on the type, your environment, and the manufacturer.

If you don’t keep your home air filter up to snuff, it could impact the quality of air inside your home. At the very least, this could mean that your loved ones become sneezing and hacking or even worst.

Without proper air filter replacement, it could lead to poor indoor air quality.

How Often Should Air Filters Be Replaced Generally?

Most air filters should be replaced every three months. However, if you have pets or live in a dusty area, you may need to replace your air filter more often. Some air filters like Merv 8 can be cleaned and reused. Check your air filter’s manufacturer’s instructions to see if this is an option for you.

Factors that Affect the Need for New Air Filters

Many factors affect the need for new air filters. Here are some:

Level of Air Pollution

The most important factor is the level of air pollution in the area where the air filter is located. If the air pollution is high, the air filter will need to be replaced more often.

Amount of Dust

As the amount of dust in an area increases, the need for new air filters also increases. This is because air filters remove dust from the air, and over time, they become clogged with dust and need to be replaced.

The amount of dust in an area can be affected by many factors, such as the time of year, the type of area, and the level of activity in the area. During the summer, areas with more dust may need to have their air filters replaced more often than during the winter.

The Location of Your System

If your system is located in a dusty or dirty area, it is more likely to need new air filters more often. If you have a lot of pet hair in your home, it can also clog up your filters and cause them to need to be replaced more frequently. It is important to check your air filters regularly and replace them when they become dirty or clogged.

Level of Humidity

As the level of humidity in the air increases, the need for new air filters also increases. This is because air filters are designed to remove moisture from the air, and when the air is more humid, there is more moisture for the filter to remove.

Additionally, air filters can become overloaded with moisture if the humidity is too high, which can lead to reduced effectiveness and even failure. As a result, it is important to monitor the level of humidity in your home and replace your air filters more frequently when the humidity is high.


Colder temperatures mean that the air is drier, which can cause the filter to clog more quickly. Warmer temperatures can cause the filter to become saturated with moisture, which can also lead to a shorter lifespan.
