Choosing the right type of air conditioner filter is important for you and your family. Pollutants come in several sizes, and the type of filter you choose determines which sizes are captured and which ones will pass through. If you or someone in your home suffers from allergies, you will want to choose one that is as efficient as possible in removing pollutants from the air.
The standard air filter has a cardboard frame and is made of spun fiberglass. It is relatively inexpensive, but does not remove smaller particles from the air and will only remove about 10 percent of pollutants. This type of filter should be replaced every month, which can be a problem if the air intake is difficult to reach.
The multiple pleats in this style mean increased surface area to catch pollutants. They do a much better job than the standard air filters, but are more expensive. This style will need to be replaced about every three months. If you choose a pleated filter, you will be removing about 30-40 percent of pollutants out of the air.
This style of filter will remove about 90 percent of pollutants from the air, but they are more expensive than either standard or electrostatic filters. They last for up to three months. This type of filter is a good choice if you or someone in your home has allergies or respiratory issues.
These filters remove close to 100 percent of pollutants from the air, which makes them an ideal choice if someone in your home has allergies or asthma.
This type of filter removes up to 95 percent of pollutants in your home. If your goal is to find an economical filter, the standard or pleated filter would be your best bet. To get the cleanest air for your home, you will want to spend a bit more to buy either a HEPA or electronic filter.
