3 Types of Air Filters: Which One is Right for You?

This type of filter consists of fiberglass fibers in layers placed one on top of the other. A pleated or polyester filter is usually a significant step forward over a fiberglass filter. This disposable air filter is the most common type. The layered fiberglass fibers are placed on top of each other to form the filter media and are typically reinforced with a metal grid that supports the glass fiber to prevent failure and collapse.

These filters are similar to fiberglass filters, but generally have greater air flow resistance and a superior ability to stop dust. To measure filter efficiency, experts use the minimum efficiency reporting value (MERV). MERV is a graph that classifies filters based on their ability to capture particles. The rating ranges from 1 to 16, with 16 given to the types of air filters with the best filtering capacity.

MERV ratings for different filter types vary by quality and manufacturer. It is always mentioned on the package. Despite their popularity, these filters do not contribute much to indoor air quality. They can only filter about 20% of particles that are around 3.0 to 10.0 microns in size.

Particles of this size only include dust, carpet fibers and pollen. Pleated filters consist of a medium fabric made of polyester or cotton. The material is organized in pleats to increase the surface of the filter. Therefore, filters that have more pleats are more effective than those with fewer pleats.

These filters are slightly more expensive than fiberglass filters but they are also more effective against pollutants. They even capture smaller air pollutants, such as pollen, pet dander, and mold spores. Pleated filters are available in both reusable and disposable versions. Due to the high efficiency of these filters, they are popular with people who have allergies to air conditioning or other respiratory problems.

However, these filters are more expensive than fiberglass filters and pleated filters. UV light filters kill bacteria and viruses with short-wave UV light. The germicidal radiation from the UV lamp from these filters disinfects the air as it passes. They are also excellent for clearing the space of harmful microorganisms, such as mold spores.

Second, while UV light filters remove bacteria and viruses from the air, they do little against contaminants such as dust. As a result, these filters are generally part of a more advanced filtration mechanism, such as HEPA filters. These filters create static electricity by using a blend of cotton and paper fibers. This static then acts like a magnet and traps contaminants inside the filter screen.

As this prevents allergens from spreading in your home, electrostatic filters are ideal for people who have allergies. Electrostatic filters often also have a carbon filter to improve efficiency. This type of AC filter can be flat panel or pleated. They also come in washable and disposable versions.

Filter media filters consist of a paper-like material folded into folds inside a metal cabinet. While the filter is no larger than six inches, the pleated material can cover 75 square feet when unfolded. This larger surface area makes media filters seven times more effective than standard air filters. The large surface area also explains the extended service life of the media filters.

These filters can last up to 2 years depending on the environment. Experts recommend that people in industrial areas or with weak immune systems opt for media filters instead of other types of air conditioning filters. As a general rule, it is recommended to clean air conditioning filters every 250 hours of use. While this cleanup is essential, it can often overlook your to-do list.

We recommend using smart thermostats or smart AC controllers that send reminders when the next cleaning is due. When it comes to choosing an air filter for your home or car, there are three main types: paper, fiberglass and pleated air filters.

Paper air filters

are the most common type in cars today due to their affordable price tag but they may not be suitable for all cars as they work better for small cars and geographical areas where there is not much pollution or dust. Paper filters are not reusable and it is important to replace them regularly.

Fiberglass air filters are disposable and economical but they don't do a great job at preventing dust and other smaller contaminating particles from entering your home or car's HVAC system so if you or someone in your family has allergies or has respiratory problems this type of filter may not be powerful enough to help relieve or prevent respiratory problems. Pleated air filters provide better airflow in HVAC units and are suitable for capturing only large particles but they can remove up to 99% of airborne particles including pollen or mold which makes them ideal for people who suffer from allergies or respiratory problems. UV air filters kill bacteria, viruses, molds and other pathogens by destroying their DNA using powerful short-wave ultraviolet light while aluminum air filters have high strength and durability and can last up to 2 years depending on the environment. As you can see there are many different types of air filters available on the market today so it's important to choose one that best suits your needs whether it's for your home or car.
