Air Filters: How To Choose A Filter For Your Air Conditioning System

For those who have an air conditioning system, the first step in keeping it running smoothly is to ensure you have a compatible filter. Here’s everything you need to know about air filters and how to choose one that fits your needs.

What is an air filter?

An air filter is an important component of your air conditioning system. It absorbs dust, pollen, and other particles from the air and helps to keep your system running smoothly. There are many types of air filters, so it’s important to choose the one that best fits your needs.

To choose the right filter for your system, you need to consider the type of air conditioning you have, the size of the filter, and the amount of pollutants in your area. Some common types of air filters are pleated filters, activated carbon filters, and foam filters.

Pleated filters are the most common type of air filter and work well for most systems. They’re made out of a series of narrow strips that trap small particles. Activated carbon filters are another popular type of filter and work well at removing harmful pollutants like smoke and gas. They’re made out of charcoal or other plant materials that absorb toxins and chemicals from the air. Foam filters are a last resort option and aren’t usually recommended for use in air conditioning systems. They’re designed to trap large particles but can also be ineffective at removing smaller pollutants.

There are a few things you need to consider when choosing an air filter for your AC unit. 

The type of air filter you need will depend on the type of AC unit you have. If you have a window or central AC unit, you will likely need a pleated or foam-type filter. If you have an AC unit that sits near the floor, like in a garage, then a pleated or foam-type filter may not be suitable because it will be blocked by debris on the floor. In this case, you may want to choose a disposable air filter or an activated carbon filter.

Another important factor to consider is the size of the air filter. The bigger the filter, the more efficient it will be at removing contaminants from the air, but it will also take up more space in your AC unit. So, if you have a small room or want to replace your current air filters often, then go for a smaller size filter.

What are some benefits of using an air filter?

There are many benefits to using an air filter in your home’s air conditioning system. Filters trap dust, pollen, mold, and other pollutants before they can reach your lungs and cause health problems. By installing a filter, you can also improve the efficiency of your air conditioning system and extend its life.

Here are some of the most common benefits of using an air filter in your home’s AC system:

  1. Air Filters Improve Air Quality 

Air filters help to improve the quality of the air that is breathed in by people living in homes with AC systems. By trapping particles such as dust, pollen, and mold before they can reach your lungs, filters can protect you from respiratory problems such as asthma. In addition, filters can also reduce the amount of noise that is produced by an AC unit.

  1. Air Filters Can Extend The Life Of Your Air Conditioning System 

Air filters can help to improve the efficiency of your home’s AC system and prolong its life. By capturing smaller particles than regular filters, pleated filters may be more effective at improving air quality while saving you money on energy costs over time. When it comes to cooling your home during hot weather conditions, a properly functioning AC unit will use less energy than one that does not have a filter installed.

How often should you change your air filter?

The American Lung Association recommends changing your air filter every six months. You can usually find the filter replacement schedule for your specific air conditioning unit on the manufacturer’s website or in the owner’s manual.

How long can it last before replacing a new one?

To choose the best air filter for your home or office AC unit, it is important to understand how filters work and how often they need to be replaced. The lifespan of an individual air filter can vary depending on the environment it is used in and the type of filter media. However, a general rule of thumb is that an air filter will last anywhere from 6 months to 2 years. If you notice that your AC unit seems to be struggling more than usual to cool your home or office, it may be time to replace your air filter.


If you’re like most people, you turn on your air conditioning unit in the summer and crank up the temperature to unbearable levels. All of a sudden, you notice your energy level dropping, asthma symptoms worsening, and even some sicknesses starting to show up. It’s time to take action! In this article, we’re going to talk about how to choose the right filter for your air conditioning system and help you get your home cooling system back under control.
