How To Choose The Best Air Filter For Your Air Conditioning System

Your air conditioning system needs to be kept in good condition for you to stay cool and comfortable during the summer months. A dirty air filter will cause your system to work harder and heat up more often, so it’s important to choose the right filter for your needs. In this article, we’ll outline the process of choosing the right filter, as well as recommend a brand and model of air conditioning system filter that we believe will work best for you. Thanks for reading!

An introduction to air filters

Several things must be considered when choosing an air filter for your AC system. The type of filter, the size of the filter, and the potential contaminants that the filter should trap are all important factors to consider. In contrast, you can install a 14x20x1 filter to keep dust and other microparticles away from the house.

When it comes to filters, there are three main types: activated carbon filters, ozone generators, and chemical filters. Each has its advantages and disadvantages.

Activated carbon filters are already built into many air conditioners and are very popular because they are effective at trapping contaminants. However, they can become clogged over time and need to be replaced more often than other types of filters. 

Ozone generators produce ozone which can kill bacteria and other airborne agents. They are less commonly used because they require a power supply and may not be effective in all environments. 

Chemical filters work by absorbing chemical byproducts produced by contaminant particles and turning them into harmless products. They are usually more expensive than other types of filters but can be easier to clean and maintain if you have trouble with activated carbon filters clogging up or needing replacement frequently.

How often should you change your air filter?

It is always a good idea to change the air filter on your air conditioning system regularly. Depending upon the type of filter, you should replace it every 6, 12, or 18 months. Even if you do not notice an increase in your energy bill, the filter will still be doing its job and protecting your investment. Moreover, by regularly cleaning any dirt and dust that accumulates on the filter, you can prolong its life span.

The different types of filters

There are a few things to consider when choosing an air filter for your AC system. The type of filter, the size of the filter, and the type of housing will all affect the performance of your AC.

AC filters come in three basic types: pleated, electronic, and foam. Pleated filters are best for removing large debris from the air and are usually found on the system with high CFM ratings. Electronic filters use sensors to measure and adjust their operation based on particle size or pollutant levels in the air. Foam filters have been largely replaced by electronic filters due to their superior performance at reducing dust and particles down to 1/10th their original size.

Systems with filtering requirements over 1000 cm should use a foam filter while systems rated between 500-1000 Cfm can use either a pleated or electronic filter. Systems with less than 500 cm should use a pleated filter only if it has a high MERV rating (medium efficiency REAR surface). Regardless of the filtering requirement, always replace your AC filter every six months or when it starts showing signs of wear.

The difference in filters between the sealed system and disposable

Different types of air filters are available on the market, and it can be hard to decide which is the best for your specific needs. This article will help you decide by comparing two different types of air filters: sealed and disposable.

Sealed Air Filters

A sealed air filter is a more traditional type of air filter that uses a cartridge to trap particles. These filters can last between six and twelve months, but they require periodic replacement because the cartridges eventually get clogged. The upside to using a sealed air filter is that it’s effective at trapping particles and there is little risk of dust or pollen getting into your home. However, these filters must be replaced regularly, and they can be quite expensive.

Disposable Air Filters

A disposable air filter is a newer type of air filter that uses aWhen compared with sealed air filters, disposable air filters have several advantages. For one, they don’t require regular replacement as the filters are designed to last only 10-20 days max before they need to be replaced due to particle accumulation. Furthermore, this type of filter doesn’t create any dust or pollen issues because it’s not intended to trap them in the first place. Additionally, disposable air filters are cheaper than sealers and you only have to replace them when they get clogged which means you’ll avoid spending hundreds of dollars on replacements over time.

High-Efficiency Particulate Air (HEPA) filters vs other filters

There are a few key factors to consider when choosing an air filter for your air conditioning system. First, the filter should be high efficiency. This means it will trap more particles than other types of filters. Second, the filter should have a compatible size and shape for your system. Third, the filter should be easy to clean. Finally, make sure the filter is affordable and durable.


After reading this article, you should be able to better understand how to choose the best air filter for your air conditioning system. By choosing the correct filter, you will be able to prolong the life of your AC unit and reduce any potential damage that could occur. This is an important step in ensuring that your home remains comfortable year-round!
