HVAC systems have air filters that trap particles, such as pollutants and allergens, to stop them from spreading throughout homes. These filters help improve your indoor air quality, so it’s important to make sure you get the right one for your Indianapolis home. Learn more about different types of air filters to choose from depending on your home’s particular needs.

Ratings for Air Filters

You can tell how effective air filters are at trapping particles by looking at their MERV rating. This rating, which stands for minimum efficiency reporting value, ranges from one to 16. Lower ratings indicate fewer particles that are caught, while higher ratings indicate better effectiveness.

Different Types of Air Filters

Fiberglass Air Filters

These air filters are among the more common kinds used in residential homes. They’re inexpensive and easy to buy in local stores. Fiberglass air filters are built to catch bigger particles, though, which can be a drawback if you have allergies. Their MERV ratings of one to four indicate that they’re not made for trapping smaller particles, including pollen.

Pleated Air Filters

These HVAC filters come with varying numbers of pleats and have a MERV rating between six and eight. They’re made of polyester or cotton and can do a better job of trapping smaller particles compared to fiberglass filters.

Disposable Electrostatic Air Filters

These filters, which are made of polyester, are good for trapping pollen and other allergens. They have MERV ratings that are usually ten or higher. One drawback is that these filters can strain your HVAC system due to reduced airflow.

Washable Electrostatic Air Filters

These air filters are also effective at catching smaller particles, such as dust. They have MERV ratings of ten or higher and can be reused several times before they need to be replaced. Keep in mind that these filters can become moldy if you don’t let them dry completely before using them.
