Pleated Filters

HVAC Filters

Pleated filters are one of the most common types of mechanical filters. They are generally used in air conditioning and heating systems. They can also be found in many other applications such as water filters in our homes, oil filters in our automobiles, process filtration etc.

Material and Construction
The pleated filters are generally made with a cardboard frame that is bonded together with some glue.

Thickness
Pleated filters are found in a wide range of thicknesses from 1 to 6 inches.

Efficiency of Mechanical Filters

The most convenient and effective way to increment the particle collection efficiency of mechanical filters is to increase the filter media density using small denier fibers. This makes the penetrations even smaller and increases the screening or straining mesh size. But one of the main problems with it is that any increment in filter density significantly increases resistance to airflow thus decreasing the airflow through the filter. The most efficient way to overcome this problem is to extend the surface area by pleating the filter medium.

• It reduces the airflow velocity through the filter and decreases overall resistance to airflow so that pressure drop is reduced.
  
  
• In addition to that, pleating of filter media enhances the total area available for filtration and, thus, extends the useful life of the filter.
  
  
• Their (pleated media filters) efficiency is much higher than for other dry-type filters.

Benefits of Pleated Filters

The pleated filters serve better than the flat surface filters. The flat surface materials, without being pleated, would clog with dust in a matter of days. It can be problematic for the system and would lead to a decay in the performance and even equipment failure. Pleating increases the surface area of a filter and extends the useful life of the filter. They require monitoring and need to be changed so that they do not become plugged with too much dust and limit the airflow through cooling/heating equipment. Some pleated air filters are provided with a wire mesh on one side. It helps the filter maintain its shape and prevent from collapsing under the pressure from air passing through it.

Buying Guide
Before you select any pleated air filters, you should consider certain points, which would prove beneficial in the long run of your filters.

• The first thing you should plan that how much money you are willing to set aside for these filters.
  
  
• After it has been decided, then you should look for an air filter company that will provide you with the air filter that you need.
  
  
• There are a number of pleated air filters available in the market. You should do some research and try to find out the specifications of each one.
  
  
• Once you get an idea of different types of pleated filters and their uses, then your selection will be much easier to accomplish.
  
  
• You must know their efficiency rate and also that how they will perform inside your various appliances.
  
  
• Pleated air filters are used for different types of applications. It will be good to see that whether the specifications, that are needed for your item, are available or not. e.g. Air conditioners work differently than furnace filters.
  
  
• The entire process will take some time to choose a perfect pleated air filter, but they will provide you with many years of excellent service.
