One of the easiest things that you can do to maintain your HVAC system is to replace the air filter regularly. This vital part of the system is what keeps all dust and debris from traveling through your home when the HVAC system is in use. While replacing the air filter is a relatively simple process, you may not be aware of all the options you have when selecting one. Here are 4 types of air filters you'll find at your local home improvement store.


The cheapest air filter that you'll find are the ones constructed with fiberglass. Their low quality means that they typically last about a month, and have to be replaced often to keep the HVAC system running properly. The filters are also less effective at trapping dust and debris, so your air quality will suffer as a result of this cheaper filter.


A pleated filter is a very popular filter type for homeowners. That is because they're known for being strong, effective, and durable. They have no problems trapping pollutants in the air, such as pet dander, pollen, or dust mites. When you hear recommendations to change your air filter every 3 months, this is referring to using a filter like the pleated variety.


Many homeowners like having a washable air filter because they are less wasteful than the types that are thrown out after being used. In addition, not needing to have an extra air filter on hand means that it is more likely that the filter is cared for. You'll be saving money over the years by not needing to replace the filter so often. That said, expect to replace a washable air filter every 3-5 years.


A high-efficiency air filter is also referred to as a deep-pleated filter. While this type of filter is typically used for commercial buildings, they can be used in a home if the HVAC system supports it. They are much thicker than the typical air filter, but effective at removing 25% of the particles in the air, which is much better than any of the previous filters.

Replacing the air filter is only one part of maintaining an HVAC system. When a problem does occur, you'll need professional help to fix it. Know the contact information for a local HVAC service company for air conditioning repair in your area so you can call for more help
