Sorting Through Your Air Conditioning System's Filter Options

Last updated 5 years ago

Your air conditioning system is critical to ensuring your home or business stays comfortable during the hot Mid-Atlantic summers.  A properly functioning filter will help your system perform better and reduce operating costs. You can also create a healthier and safer environment for your home or business by selecting the right type of air conditioner filter for your needs. Read on to learn about the most common types of air filters and what you should consider when choosing filters for your HVAC system.

Invest in Quality
All filters are rated based on the size of the particles that they can filter out of the air. A qualified HVAC technician can explain these ratings to you and help you select the most appropriate filter to fit your air quality needs. Generally, higher-quality air filters will trap more air pollutants and last longer than less expensive options. Better-quality filters will also absorb harmful indoor air pollutants, such as smoke, pollen, pet dander, and chemicals, creating a healthier indoor environment.

Know the Basic Types of Filters
Standard air filters made of woven fiberglass with cardboard frames are the most inexpensive filters on the market. These capture roughly ten percent of the largest particles from the air. Pleated air filters have a surface that is folded like a fan. This larger surface area removes approximately 40 percent of the particles in the air. Electrostatic and electronic filters use an electric charge to attract up to 90 percent of pollutants in the air to the filter, while hospital-grade high-energy particulate air (HEPA) filters can remove virtually all harmful particles from the air.

Change Your Filter Regularly
No matter what type of filter you choose for your air conditioning system, it is essential that you replace the filter regularly. A dirty filter will block normal air flow and reduce the system’s efficiency significantly. You’ll lower your energy bills and help prevent your system from breaking down by maintaining a clean filter.
