Choosing the Right Air Filter for Your Alabama Heater and AC System

Published on: February 23, 2012

If you have just purchased a new heating unit or air conditioner for your Alabama home, the first question you face is which type of filter to purchase. A professional heater and air conditioning repair or installation company in Alabama should be able to provide you with some guidance. You can also go to a home improvement store to purchase a filter, unless the manufacturer has not made them available to the general public. In that case, you will have to look for a heater and air conditioning repair or installation provider that is an authorized dealer for the manufacturer to order a new filter.


Standard air filters are the most common and the least expensive, but they trap only up to 10 percent of pollutants in the air. A standard filter is made with fiberglass and cardboard. It needs to be changed monthly in order to remain effective. If someone in your home has asthma or is an allergy sufferer, you may want to consider a filter that is able to catch more of the microscopic pollutants in the air that you can’t even see.

A pleated air filter is slightly more expensive because it can trap up to 40 percent of airborne pollutants. It has a wider surface area and is folded in a fashion similar to a paper fan. If you have not used pleated air filters in the past, ask an Alabama heater and air conditioning repair or installation company to show you how to install it.


An electrostatic filter attracts dirt particles to it using an electric charge. They cost up to $100, but only need to be changed on an annual basis. Electrostatic filters go over an opening in your furnace. They also help the furnace to run more efficiently all year long.

If you have tried all of these filter types and still have issues with allergies or asthma in your home, contact a heater and air conditioning repair or installation company to discuss your options. You may benefit from installing an air purifier or dehumidifier in your home to reduce symptoms.
