Air filters are an important part of your HVAC system because they trap contaminants like dust and dirt that could otherwise harm your HVAC system. If your system has been running without a filter for a long time, it may be time to replace your air filter. You should do this at least once a year, and more frequently if you have pets or live in a dusty area. If you’re in the process of installing a new HVAC system, you may want to consider purchasing a pre-filters for your ductwork and air handler. These can trap larger debris before it makes its way into the smaller filters in your HVAC system. They are also helpful if you’re doing a duct cleaning, as they can protect your HVAC equipment from debris and dust that might be kicked up while you’re working in your home.
When shopping for an air filter, look for the following features:- Size: Make sure the filter is large enough to cover the entire length of your ductwork. If it’s too small, it won’t trap enough dust.- Material: Look for a filter that is made from either polyester or fiberglass. Fiberglass filters are more effective at trapping dust and other contaminants. They may also be more expensive.- Number of layers: Look for a filter that has at least three layers.- Airflow: Make sure the filter has a large enough flow of air to prevent it from getting clogged too quickly.- Manufacturer: Make sure the filter is from a reputable manufacturer. You may want to purchase a filter with a warranty to ensure that it lasts as long as the rest of your HVAC system.
There are three main types of air filters: - Paper filters: Paper filters are the most common type of air filter. They are inexpensive and easy to replace, but they don’t trap as much dust as other types of filters.- Fiberglass filters: Fiberglass filters are more effective at trapping dust and other contaminants. They may also be more expensive.- HEPA filters: HEPA filters are the most effective type of air filter. They are usually used in hospitals and other high-risk environments, but can be used in homes as well.- These filters trap 99.97% of airborne particles and may be a good choice if you have a sensitive respiratory system.
When replacing an air filter, you should follow these steps:- Shut off the HVAC system and unplug any electrical equipment.- Open up the ductwork and inspect the filter. Make sure you can see if it is completely clean. If not, you may want to consider replacing it.- Find the filter and remove it. Make sure you put the new filter in the correct direction. Make sure you reinstall the filter in the correct location.
