What Are The Different Types Of AC Filters?

AC filters keep out micro particles and dust away. They maintain indoor air quality as well. Failure to clean or replace them can strain your AC’s performance, leading to air conditioning repair in Princeton, MN. There are different types of filters for the optimal performance of your AC unit, each having specific features.

Standard Fiberglass Filters

Standard fiberglass filters are the most basic type of AC filter. They are inexpensive and protect your air conditioning system from large dust particles. They are not very effective at capturing smaller particles, such as pollen, mold spores, or pet dander. 

Pleated Filters

Pleated filters are more efficient at trapping dust, pollen, and pet dander, making them a popular choice for homeowners seeking better air quality. Their polyester or cotton folds provide a larger surface area to capture particles. Regular replacement is necessary to maintain their effectiveness as part of air conditioning services.

HEPA Filters

High-Efficiency Particulate Air (HEPA) filters are the gold standard for air filtration. They capture up to 99.97% of particles as small as 0.3 microns, including dust, pollen, mold spores, and even some bacteria and viruses. They are ideal for households with allergy sufferers or those who prioritize superior air quality. Not all AC units can accommodate them, so it’s essential to consult with a professional during air conditioning maintenance.

Electrostatic Filters

Electrostatic filters use an electric charge to attract and trap particles. They come in both disposable and washable forms. These filters are effective at capturing a wide range of particles, making them a good choice for improving indoor air quality. Regular cleaning or replacement ensures their proper function.

UV Filters

UV filters use ultraviolet light to kill bacteria, viruses, and mold spores. They are often used in conjunction with other types of filters to provide an additional layer of protection. UV filters are particularly beneficial in preventing microbial growth on the coils and other parts of the AC unit.

Having the right AC filter is key for indoor air quality and optimum cooling for your AC. Call Rol Air Repair for proper cleaning and maintenance to maintain these key performance elements.
