Types of home air filters

Home air filters are designed in a variety of types to cater to diverse air quality needs and HVAC system requirements. Mechanical filters, such as fiberglass and pleated filters, are widely used for trapping larger particles like dust and lint. For those concerned with smaller, more elusive particles, electronic air cleaners including electrostatic precipitators and ionizers, utilize an electrical charge to capture them effectively.

When it comes to neutralizing odors and gases, gas phase air filters and activated carbon filters stand out for their ability to adsorb unwanted smells and chemical vapors. The thickness of the filter, represented by options like 1-inch, 4-inch, and 5-inch air filters, also influences their efficiency and how often they need to be replaced. Selecting the right type of air filter is key to enhancing indoor air quality and ensuring the longevity of your HVAC system.

Mechanical filters

Mechanical filters serve as the first line of defense, capturing particles such as dust, pollen, and pet dander by physically trapping them in the filter material as air circulates.

Fiberglass filters

Fiberglass filters, a common type of mechanical filter, are constructed from spun fiberglass material and are designed to trap large airborne particles, offering a basic level of air filtration.

Pleated filters

Pleated filters feature a folded design that increases the filter’s surface area, enhancing its ability to capture more particles and improve air quality more effectively than flat-surface alternatives.

Electronic air cleaners

Electronic air cleaners employ an electrical charge to attract and trap airborne particles, significantly purifying the air as it moves through the HVAC system.

Electrostatic precipitators

As a subset of electronic air cleaners, electrostatic precipitators charge airborne particles before capturing them on oppositely charged collector plates, which require periodic cleaning to maintain efficiency.


Ionizers work by releasing ions into the air that attach to particles, increasing their weight and causing them to settle out of the air, thereby reducing airborne pollutants.

Gas phase air filters

Gas phase air filters specialize in removing gases and odors from the air through adsorption, typically using materials like activated carbon to capture these molecules effectively.

Activated carbon filters

Activated carbon filters are adept at trapping gases, odors, and volatile organic compounds (VOCs), leveraging the highly porous nature of activated carbon for superior adsorption.

1-inch Air Filters

1-inch air filters are widely used in residential settings, providing essential protection and filtration. They require regular replacement to maintain air quality and system efficiency.

4-inch and 5-inch Air Filters

4-inch and 5-inch air filters offer a thicker filtration medium, which translates to longer service intervals and enhanced efficiency in particle capture, making them a preferable choice for those seeking higher performance from their HVAC system.

Factors in choosing an air filter
