As the name suggests, the primary function of an air conditioner is to improve the air quality in its surrounding. That however cannot be possible until high quality air filters are used. Using these air filters is not the only requirement though; their thorough maintenance is paramount in eliminating the contents of dirt, debris and pollen etc.
An air filter traps elements like pollen, dust, pet dander, bacteria, smog, smoke, which consequently clog it. With the passage of time this blockage increases to an extent that the air quality passing through the filter starts to suffer. Another side effect of this is the stuffing of debris in the evaporator coil which increases the energy costs, up to 15 percent.
Just remember that air filters are to air conditioners what lungs are to our own bodies, and imagine how much difficulty you will have in breathing if your lungs get clogged.
How to Replace an Air Filter in AC Unit?
Cleaning air condition filters regularly is a good way to ensure a high quality air, however these filters need to be replaced once their life is over. The procedure to do that is extremely simple.
You can start off by first finding the filters. Rather than looking for them blindly, just pick up the manufacturer’s manual and see the filters are located. Generally, they are located in home’s ductwork or furnace unit.
The filter can be accessed by removing either the metallic strip or the screws. After doing that, take out the filter gently, making sure that your hand does not touch the fabric. Now take the measurements of the filter and procure a new one with the same dimensions. You can also take the old filer to the store so that there is no chance of wrong procurement. Place the new filter in the compartment, making sure that you sort out the air in/ air out sides correctly. Now close the compartment cover and put the metallic strip or the screws back.
Types of Air Condition Filters
There are many types of air condition filters and are basically differentiated by their operational principles and the amount of pollutants they can trap.
- Standard Filters. Made of spun fiberglass and cardboard frames, standard filters are the least efficient type of air condition filters, required to be changed monthly. They are capable of removing only 10 percent of pollutants from the air and are not effective against bacteria and allergens.
- Pleated Filters. Filter surfaces are folded back and forth to increase the filtering area in this type. They can remove about 35 to 40 percent pollutants from air.
- Electrostatic and Electronic Filters. The filter material is charged and attracts the contaminants in the air, making it about 90 percent clean. Electronic filters operate on nearly the same principle and are a tad more effective.
- High Efficiency Particulate Arresting Filters. HEPA, as they are commonly known, are the most effective type of filters, and can improve the air quality up to 99.97 percent.
