Air conditioning filters prevent dust and dirt from clogging the system and contaminating the air. Different types include glass fiber, pleated fiberglass, permanent mesh, electrostatic, and HEPA filters. It’s important to clean or replace filters regularly to avoid negative effects on energy consumption and system failure. HEPA filters are the most effective.
Air conditioning filters are devices that keep dust and dirt from clogging the air conditioning system and contaminating the air. In a building the filter is usually placed in the large return air duct. When air is drawn through the filter, dust and dirt get trapped in the fibers. A good filter can also be responsible for trapping allergens. All filters must be cleaned or replaced regularly.
It’s important to make sure your air conditioning filters are clean and the right size for your air conditioning unit. A filter that is too small or dirty can have several negative effects. Effects include increasing the amount of energy consumed by the drive, reducing cooling or heating, and contributing to drive failure. The right filter will help keep the air and air conditioning system clean and functioning properly.
There are different types of air conditioning filters. The first type is the glass fiber filter. It’s the cheapest and typically only traps large particles, leaving smaller particles to travel through the air. These filters are not meant to be cleaned but must be replaced. It is important to ensure that these filters are not in use while dirty as they may cause system overload.
Pleated fiberglass air conditioning filters are more efficient at trapping dirt. The material it uses is more tightly woven. Therefore, as air passes through the fibers, more dust and dirt can be trapped. The surface area of these filters is also pleated which increases the surface area. This means that a pleated filter will be able to trap more dust than a flat filter of the same size.
Permanent mesh air conditioning filters can be made from different types of material. Therefore, their effectiveness may vary. These filters, however, are washable. After washing, some need to be sprayed with adhesive to trap dust and dirt. You may even need to change them eventually due to wear.
Electrostatic air conditioning filters are made from a material that produces a charge when air passes through it. This charge draws dirt and dust from the air and holds it on the surface until it can be washed away. Electric air conditioning filters are similar, except that they use an electrical energy source to do their job. It consists of a pre-filter and main filter that work together to filter the air. The pre-filter traps large particles and the main filter traps smaller ones.
High efficiency particulate filters, or HEPA filters, are probably the most effective filters. They are said to remove 99.97% of particles that are 0.3 micrometers in diameter, smaller than the diameter of human hair. In this filter, the fibers are arranged randomly. It also contains pleats that increase the surface area, making the air filtration system more effective. HEPA filters are also used in vacuum cleaners and hospital rooms.
