When you think of air pollution, you probably think of smog and haze. However, indoor air pollution is actually a bigger threat than you might think. According to the EPA, more than 90% of us spend 90% of our time indoors. That means we are breathing in high levels of pollutants from our household appliances and materials every day. Indoor air pollution has been linked to a wide range of health issues such as irritation of the eyes and skin, headaches, and dryness in the throat and lungs. If you live in an apartment or house with a central air conditioning system, you may be concerned about how your filter is affecting the quality of air in your home.

Air filters can be installed in either your central air conditioning system or in your home’s ductwork to capture harmful particles and microorganisms floating in the air.Air filters are available in different sizes and shapes, and you can select the one that is best suited for your home and air conditioning system. Some filters are designed to trap both large and small particles, while others are specialized for trapping specific types of pollution.

There are two types of filters that you can use with your air conditioning system: a pre-filter and a final filter. A pre-filter is installed in the air duct before the main filter and is meant to trap large dust and debris. A final filter is installed after the pre-filter and is used to trap extremely small particles.You should use the final filter for your air conditioning system to trap extremely small particles such as dust, dander, and mold spores. A pre-filter is only suitable for central air conditioning systems because it can trap very large dust and debris.
