The Different Types of Air Filters: Keeping Your Home Clean and Healthy

When it comes to keeping your home or office air clean and healthy, air filters are an essential part of any air conditioning system. There are a variety of different types of air filters available, each offering different levels of protection and efficiency. Let's take a look at some of the most common types.

Disposable Fiberglass Filters

Disposable fiberglass filters are the most commonly used type of filter. They are relatively inexpensive and easy to install, making them a popular choice for homeowners. These filters work by trapping dust, pollen, and other airborne particles as air passes through them. However, they don't offer the same level of protection as other types do and need to be replaced regularly in order to remain effective.

Pleated Filters

Pleated filters offer more efficient filtration than disposable fiberglass filters. They consist of a combination of synthetic media and paper that is pleated together to create a larger surface area for trapping particles. This design allows them to capture smaller particles than fiberglass filters can, making them more effective at filtering out airborne contaminants. Pleated filters also need to be replaced regularly in order to maintain their effectiveness.

HEPA Filters

High-efficiency particulate air (HEPA) filters are the most effective type available on the market today. They use dense material that traps even the smallest particles such as mold spores, pet dander, and smoke particles with up to 99.97% efficiency rate! HEPA filters are often used in hospitals or medical facilities due to their high level protection but need replacing every six months or so.

Activated Carbon Filters

Activated carbon filters use activated charcoal which absorbs odors and chemical vapors from the air. These kinds of filters are often used in areas where there is a lot of smoke or chemical fumes, such as near industrial plants or wood-burning stoves. Activated carbon filters can also help reduce allergens in the air by trapping pollen, pet dander, and other irritants.

Electrostatic Filters

Electrostatic filters use an electrostatic charge which attracts particles as they pass through it. This type is more efficient than traditional fiberglass or pleated filters because it can capture smaller particles that would otherwise pass through other types. Electrostatic filters also don't need replacing as often as others do.
