When deciding what kind of HVAC air filter you want to use, there are a number of factors to consider. Some are designed to be cleaned more frequently than others while some are more efficient. Here are five of the most common types of air filters for use in the Tulsa and Broken Arrow region.Disposable FiltersThese are the most common air filters that are used because of their economical pricing and ease of use. They should be replaced every six to eight weeks for maximum efficiency. They are not designed to be washed. This will only create holes which will make them less efficient. As for efficiency, these are what is described as "boulder catchers". They can only filter the extremely large particles flowing throughout your system, for instance, many can't stop salt when sprinkled on top of them.Permanent FiltersThese come in various sizes to fit your needs and do not need to be replaced. They are easily removable to allow the user to clean them. It is recommended that you clean them every 30 to 60 days to keep them operating at full power. These are normally the most restrictive type air filters due to the long lasting fiber the filter is made out of. This can put a major strain on airflow, causing increased dust, reduced comfort, and potential harm to the system.Hammock FiltersThese come in a 20-foot roll, allowing you to cut the filter to the appropriate size for a your hammock frame. Once cut, you simply place them in the frame and trim any excess. They should be disposed and replaced every 60 days. This is similair to the disposable in efficiency. Most homeowners are bothered by the time it takes to maintain these.Electrostatic Air CleanerThese use electrostatic attraction to trap charged particles in the air and are very efficient at arresting dust, pollen, bacteria and other airborne pollutants. They are permanent and can be easily washed every month. Again, these type of filters are extremely restrictive to air flow.Large Pleated Media FiltersThis type of filter is popular because of the low maintenance required to keep them lasting for at least five years. They tend to have very high efficiency levels and use a media cartridge that has to be replaced only every six months. There are several different "levels" of pleated media. You don't have to get the most expensive! Usually those are very restrictive as well.If you are wondering what type of filtration system is best for your and your family, just ask your technician.
